Preventive Maintenance Strategies for Pavement and Gravel Roads

Instructor Sam Gregory presented two separate workshops: Pavement Preventive Maintenance on May 4 in Lynchburg and Maintenance of Gravel Roads on May 5 in Lynchburg. At each separate workshop, he reviewed maintenance techniques and provided examples of current best practices from across the country. Intended for public works directors, supervisors, road masters, crew foremen and equipment operators, the workshops provided a solid background for planning and executing important preservation techniques.
“Anybody can manage public works projects when funds are readily available,” explained Gregory. “But when funds are limited, we need every tool to keep roads in the best shape possible. Think of it as putting oil in your vehicle to extend the life of your engine. It’s the same with roadways. We need to do preventive maintenance to extend the life of the surface.”
The FHWA’s Every Day Counts (EDC-4) program promotes proven innovations and strategies to address the challenges of limited budgets. The aim is to provide greater efficiencies in delivering projects that are better, faster and safer. One of its primary focuses is on innovations in pavement preservation – activities and technologies that do not generally add capacity or structural value, but restore the overall condition of roadways.
In support of the EDC-4 mission, the Pavement Preventive Maintenance workshop provided participants with information on selecting the correct treatment for the appropriate pavement, including requirements of sample specifications, proper pavement selection and operational oversight. The session covered the uses, benefits and applications of a variety of different innovative techniques including:
  • Micro-Surfacing
  • Ultra-Thin Friction Course
  • Slurry Seal
  • Liquid Bituminous Seal Coat.
Participants gained valuable insight about asset management, project planning, asphalt distress identification, inspection and quality control.

This half-day Maintenance of Gravel Roads session provided basic maintenance techniques for unpaved and gravel roads, including minor maintenance to major repairs and improvements. Topics included the importance of proper drainage, surface aggregate materials and operational techniques such as blading, reshaping and re-graveling. Gregory provided examples of successful approaches and materials used by agencies across the country, including Driving Surface Aggregate (DSA), an innovative material that packs tightly resulting in less breakdown and dust.
Factors used to determine when to upgrade a gravel road by paving or seal coating was also reviewed. The discussion included a cost comparison of maintaining gravel and paved surfaces.
Sam Gregory has worked for over 36 years in the transportation community. Currently providing LTAP training, course development and technical assistance support for local government agencies, he also works with the North East Center of Excellence of Pavement Technology (NECEPT) at Penn State University. He is past chairman of the Maintenance Technical Advisory Group for the Pennsylvania State Transportation Innovation Council (STIC).

Gregory spent much of his career with Penn DOT. Prior to retiring, he was the Highway Maintenance Manager in charge of Mifflin/Juniata and Perry County Maintenance Organizations, responsible for multi-year strategic plan preparation and oversight of 585 roadway miles, 582 bridges, a $12 million budget and over 110 employees.

VDOT’s Roadway Departure Crash Countermeasure Tool Gets Test-Driven

The Roadway Departure Crash Countermeasure Tool (RDCCT) was developed by VDOT in conjunction with Kimley-Horn and Associates. This decision tree tool helps users apply a decision matrix to existing roadway departure crash patterns to identify potential low-cost improvements that can be further considered along an identified roadway corridor.  The RDCCT provides a decision algorithm that considers both crash and roadway facility data in a user-friendly format, enabling transportation planners and traffic engineers to identify systemic low-cost improvements along high-risk roadways.

Roadway departure related crashes occur when a vehicle departs its travel lane, resulting in a collision with another vehicle, curb, or other roadside features (i.e. trees, utility poles, drainage structures, etc.).  There are three categories of potential low-cost countermeasures that the RDCCT considers.  The first category includes countermeasures that aim to keep vehicles on the roadway (i.e. rumble strips, wider line markings, etc.).  The second category includes countermeasures that aim to provide for a safe recovery back onto the roadway (i.e. pavement wedge, shoulder widening, etc.).  The third category of countermeasures aims to reduce the potential severity of collisions occurring on the roadside (i.e. tree removal, barriers, etc.).

Together, these three categories provide a comprehensive and strategic approach to addressing roadway departure related crash patterns.  Although several potential countermeasures are available for consideration, the applicability and feasibility for each is dependent on existing roadway geometry, pavement condition, roadway type (i.e. tangent or horizontal curve) and crash patterns.  The RDCCT was developed to consider these constraints, such that only countermeasures that are applicable to the corridor are being identified for further consideration.

UVA TTA/VA LTAP contracted with Kimley-Horn to conduct two training sessions with City of Charlottesville and City of Richmond engineering staff to test-drive the RDCCT with existing roadways having roadway departure related crash patterns. Travis Bridewell, Operations Manager for the City of Richmond, and Brennen Duncan, City Traffic Engineer for the City of Charlottesville, participated in one-on-one sessions with Ben Reim, a transportation engineer with Kimley-Horn. At each session, they reviewed the tool and its available resources, analyzed actual crash data for their specific locale, and interpreted preliminary results from the RDCCT.

The Charlottesville session focused on a segment of Barracks Road where crash data revealed a significant number of roadway departures, some of which included overturned vehicles.  Several potential countermeasures were identified for further consideration from the RDCCT, including pavement marking improvements and horizontal curve signing.

The Richmond session focused on two sections of Cherokee Road, located between Huguenot Road and Forest Hill Avenue.  Crash data revealed several crashes which involved vehicles leaving the roadway and striking roadside objects.  The RDCCT identified several potential countermeasures for further consideration, including pavement wedge application, tree removal, and the installation of object markers.

Importantly, Bridewell and Duncan provided input to guide future implementation of the tool in other localities. “Travis and Brennen were invaluable in providing key insights from the transportation professional’s point of view,” explained Reim. “They helped shape possible iterations of the tool as it relates to the RDCCT being incorporated into potential safety funding applications, as well as potential adaptations that could assist in addressing roadway departure related crashes at intersections.”

Henrico County Employees Improve Snow Plow Operations: Win Virginia LTAP’s 2017 ‘Build a Better Mousetrap Competition’

Henrico County is a large county in the Commonwealth of Virginia, with a population of nearly 350,000 people and covering over 245 square miles. Different regions of the county often experience different weather events at the same time such as rain in the east and snow in the west. As a result, public works crews are responsible for reacting in real time to the changing status of 167 subdivision routes, ranging from snow and ice removal, flooding and standing water, downed trees and power lines, and malfunctioning traffic lights.

As the manager of the county’s GIS office, Jason Collins often meets with colleagues throughout the county to discuss problems that might be rectified by GIS (geographic information system). Three years ago, he met with Steve Clark, Drainage Manager for the county, who described problems documenting when, by whom, and the type of work performed on subdivision roads. Clark described difficulties deploying crews quickly in response to citizen complaints, especially when provided with incomplete or inaccurate location information. Collins and Clark agreed that GIS might be a good way to track complaints and prevent duplication of responses. As well, they brainstormed how GIS could provide shift foremen with information about changing roadway conditions so they could make real-time adjustments in plowing strategies.

Together, they created a mobile GIS system that uses mobile devices (such as ipads and smart phones) along with ArcGIS Online (a collaborative web GIS for sharing maps, scenes, analytics and data) and the ESRI Collector app (collects, updates and logs data from the field). Data is easily transmitted between administrative offices and foremen, creating real-time information as well as graphical visualizations of the plowing status of subdivision routes at a glance. The system creates record-keeping capabilities for all snow-related activities so historical information, before and after pictures, and special notes for crews can be compiled.

Clark reports the system has been in limited use for three years with expansion to the entire county planned for next season. The program will leverage the county’s enterprise licensing agreement with ESRI, a GIS mapping software platform, and mobile devices already issued to public works staff for work-related purposes. As a result, the county will incur no additional expense to implement the new GIS system while eliminating paper records for complaints and work orders, and realizing significant potential savings by reducing re-treatments and damage complaints.

He suggested this technology could be used for additional applications such as mosquito control, leaf collection and debris in waterways. “It’s proving to be a great tool for documenting who, where, when and what was performed. It’s eliminating the need for paper records and is helping us be accountable to private citizens,” explained Clark. “Perhaps most importantly, it’s helping us to coordinate the 15 foremen, 57 city trucks, 11 hired trucks and 10 push trucks that are deployed to lay down chemicals and remove snow every time there is a snow event. That’s a massive coordination project and the GIS app can handle it with ease.”

The ‘Build a Better Mousetrap’ competition recognizes the most innovative solutions to common transportation problems, focusing on the development of tools, equipment modifications or processes that increase safety, reduce cost, and improve efficiency and the quality of transportation.  As the winner of the regional competition, the Henrico Department of Public Works’ mobile GIS entry will represent Virginia’s LTAP at the National LTAP/TTAP annual conference to be held July 17-20 in Portsmouth-Norfolk, Virginia.

“Our goal was to improve communications so quick decisions could be made about where and when to send road crews to address poor conditions or downed hazards,” said Collins. “It’s an extraordinary bonus to have our solution recognized among those of our peers and colleagues at the national level.”

Offering Transit Incentives Is A Way To Avoid Costly Infrastructure Spending

In the department of “Where Are They Now?,” Chris Hamilton is a prominent face around Mobility Lab, as one of our contributors and the former bureau chief of Arlington County Commuter Services, of which Mobility Lab is a part. He just appeared as a guest on the excellent GovLove podcast.

Host Ben Kittelson asks to learn more about transportation demand management – Mobility Lab’s bread-and-butter – and Hamilton answers: “Transportation tends to revolve around adding supply and adding infrastructure. And TDM is all about changing the behavior of people so that you better meet the demand.”
Hamilton gives the TDM example of “if the roads are clogged, rather than widen the road, which is really expensive and in tons of places we can’t even do that anymore, what if we could get more people to ride the bus if there’s not a lot of people [already doing that]? Or what if we could get more people on bikes or even walking?

Traffic: Which Boston-area Neighborhoods Are To Blame?

In rush-hour traffic, a single driver blocking the box can ruin everyone’s afternoon. But when you’re sitting on a backed-up road, cars stretching into the distance, the source of the gridlock is more of a mystery: Where’s the problem coming from? 

What’s true at a single intersection turns out to apply on a larger scale: It’s just a few drivers, relatively speaking, who jam things up for the rest of us. 

That’s the conclusion of a team of engineers from the Massachusetts Institute of Technology and the University of California, Berkeley, who have produced one of the most detailed maps of urban traffic patterns ever constructed. They did it by analyzing the cellphone records of 680,000 Boston-area commuters (they perform a similar analysis for the Bay Area). The call logs—which identify the towers used to transmit calls—allowed the researchers to trace each individual’s commute, anonymously, from origin to destination.

Judge Protects Bike Lane With Restraining Order

An increasingly unusual situation in Baltimore has led to a dubious milestone: A circuit court judge has issued a restraining order to stop a U.S. city from removing a new protected bike lane.
It's only the latest in a string of odd events, beginning with the city's decision to scrap an already-completed public process and tear out a four-week-old post-protected bike lane under construction on Potomac Street. From Streetsblog USA:
The city has already spent $775,000 designing and installing the bike lane, which had been included in city planning documents for the past five years. The project received federal funds distributed by the state and met design guidelines set by the Federal Highway Administration and the National Association of City Transportation Officials.
The local city councilperson and some neighbors are in favor of the bike lane, but other neighbors aren't — and after construction began, the neighbors who don't like the plan persuaded the mayor to reverse the public process on the grounds that the International Fire Code requires streets to have 20 feet of clearance.

FHWA Issues Record of Decision for Hampton Roads Crossing Study

SUFFOLK -- A project to expand the Hampton Roads Bridge-Tunnel and widen Interstate 64 between Hampton and Norfolk reached a major milestone this week with the conclusion of a nearly two-year environmental study. 
The Federal Highway Administration (FHWA) issued a Record of Decision (ROD) for the Hampton Roads Crossing Study on June 12. The signature of the document concludes the National Environmental Policy Act process for the study and allows VDOT to proceed with more detailed procurement and design of the project.
In its Record of Decision, the FHWA selected Alternative A as the Preferred Alternative to relieve congestion in the I-64/Hampton Roads Bridge-Tunnel corridor. Alternative A expands I-64 and the Hampton Roads Bridge-Tunnel to a consistent six-lane facility from I-664 in Hampton to I-564 in Norfolk. The expansion includes a new bridge-tunnel at the existing HRBT.
The document, a copy of which may be found here, presents the basis for the study decision, per 40 CFR 1505.2, and summarizes the mitigation measures to be incorporated in the project.
The next step in the procurement process is the anticipated release in late 2017 of a Request for Qualifications (RFQ) to potential proposers who wish to compete for a contract to design and build the project. Many details, including the final lane configuration and construction method of the new tunnel, will be determined as design and procurement advances.
Future updates on the I-64 Hampton Roads Bridge-Tunnel Expansion will be posted to the new project website at

Jim’s Journeys … Traveling the TTA Highway

Hey fans!  I gotta tell you, I'm super exhausted.  I've been all over this great state running workshops for all our great transportation employees!

Since my last update I've been to Charlottesville, Fairfax (twice) Arlington and Thornburg, putting tons of miles on my car, listening to a bunch of podcasts and eating way more bagels than I should.

The look that says
"I've been on the road
 A LOT lately."
But it has been worth it seeing class after class of students getting their work zone certification- yes, all of these class have been for Basic, Intermediate and Advanced work zone training.

Just because I've been in workshops every week doesn't mean I don't want to visit with all our great Public Works and VDOT employees.  If you want me to come down and talk about TTA and all of our awesome classes just shoot me an email- and we'll see about setting up a visit.  

If you need training and just want to set up a class contact Robin Carpenter at 434-982-2897 and she will get you what you need!

Be safe out there this summer and I'll see you on the TTA Highway!

How Does Your City's Bike Network Rank?

It takes many things to build a good city for biking, but one of them is indisputably a nice mellow network.
Just as the car boom of the 1920s was made possible by new continuous networks of paved roads, the growth of biking in the next decade will depend on building continuous networks of wide or protected bike lanes, off-street paths and low-traffic streets.
Just as importantly, bike networks need to go places — they need to connect people to each other, to jobs, to public recreation and services, to private businesses.

The Need for Safe Speeds: 4 Surprising Ways Slower Driving Creates Better Cities

This week is UN Global Road Safety Week, focused on the theme “Slow Down, Save Lives.” WRI works to make cities around the world safer and more sustainable by implementing street design and regulations that reduce vehicle speeds while supporting walking and cycling. There is a growing body of evidence on the impacts and wider benefits of such efforts, which we’ll explore in blog posts this week. 
Traffic crashes kill 1.25 million people every year and cause permanent disability to millions more. No matter the location, speed is frequently a factor.
Deaths and serious injuries are the painful and highly visible result of a lack of road safety, but we have lost more to high car speeds than we realize. What about fear of children playing on sidewalks, walking to school, or learning to ride a bike? What about people who struggle to pay high transport costs, but don’t feel safe commuting by bike?
Speeding cars can limit physical activity, use of public space and quality of life, and the impacts are felt most by the least advantaged. Lower-income residents often live in close proximity to roads with dangerously fast-moving traffic. They are also more dependent on walking, biking or public transport, which are most exposed to the danger of speeding cars. These negative impacts are even more dramatic in developing countries, where a rapid increase in car and motorcycle ownership is taking place on roads with little speed regulation.

Avoid I-95 In Northern Virginia During Weekend Road Work

Avoid I-95 During Upcoming Maintenance
Second weekend of southbound bridge deck repair; Drivers urged to use alternate routes
NOTE: Bridge work has been scheduled for this weekend, from 10 p.m. Friday, June 2 to 6 a.m. Monday, June 5.
DALE CITY – Drivers are urged to avoid I-95 in northern Virginia this weekend as lanes will be closed southbound in Dale City for bridge deck repair. Congestion and delays are expected to be extensive in both directions. After several weekends of rain cancelled the second segment of work, crews will work Friday through Sunday to complete the repairs.
  • Southbound I-95 will be reduced from three to two lanes over Neabsco Creek (mile marker 156) from 10 p.m. Friday, June 2 to 6 a.m. Monday, June 5.
  • Ramps from eastbound and westbound Dale Boulevard to southbound I-95 will also be closed to all except emergency vehicles.
  • The southbound car-only safety rest area will also be closed.
During the repairs, the 95 Express Lanes will remain open with toll pricing in effect and free travel for HOV-3 vehicles with E-ZPass Flex set to HOV mode. The lanes will be southbound beginning at 1 p.m. Friday to help alleviate backups, and will be monitored to change direction if needed. Drivers planning to head northbound this weekend are asked to be aware of this, and to plan trips accordingly for heavier-than-usual return traffic, particularly on Sunday.
The bridge, originally built in 1963, has been regularly inspected and maintained, and remains safe, but is in need of large-scale repairs to sections of the deck. The needed work will include saw-cutting and jackhammering out three bridge sections, the largest being 10 feet by 33 feet, replacing the reinforcing rebar, and pouring new concrete. Work will affect the bridge deck, joint, and abutment.
Due to the time needed to cut the large sections and set the concrete, completing this work over two weekends is necessary (as opposed to multiple overnight closures). The first segment of work was completed on April 30. Several weekends of rain postponed the remaining work until this weekend.
Drivers are urged to avoid I-95 in both directions, and to expect significant delays on all of the usual alternate routes.
Some alternate routes can be found at and are listed below.
Local drivers in Prince William County:
  • East side: Route 1 southbound to Route 234 or Joplin Road northbound to I-95
  • West side: Minnieville Road westbound to Spriggs Road southbound to Route 234 southbound to I-95
Regional drivers:
  • East side: I-495 to Route 5 (Branch Avenue) southbound to Route 301 southbound to Route 206/218 westbound to I-95 southbound
  • West side: I-495 to I-66 westbound to Route 29/15 to Route 17 southbound to I-95 southbound
