As budgets for public works stagnate or even dwindle, transportation professionals are faced with difficult decisions about the condition of their roadways. Preventive maintenance strategies can provide cost effective options, helping to slow structural deterioration and extend the useful life of road surfaces.

Instructor Sam Gregory will present 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 will review maintenance techniques and provide examples of current best practices from across the country. Intended for public works directors, supervisors, road masters, crew foremen and equipment operators, the workshops will provide 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.”

Pavement Preventive Maintenance: May 4, 2017 (Lynchburg)

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, this one-day workshop will provide 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 will cover 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 will gain valuable insight about asset management, project planning, asphalt distress identification, inspection and quality control.

Maintenance of Gravel Roads: May 5, 2017 (Lynchburg)

This half-day session will provide basic maintenance techniques for unpaved and gravel roads, including minor maintenance to major repairs and improvements. Topics include the importance of proper drainage, surface aggregate materials and operational techniques such as blading, reshaping and re-graveling. Gregory will provide 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 will also be reviewed. The discussion will include 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.
