Best Practices for Asphalt Longitudinal Joints Webinar Recording

(2 hrs., 2 PDHs)


Register online to view this webinar recording


A chain is only as strong as its weakest link and for asphalt pavement that link is often the longitudinal joint.  Despite much research, trials, studies and training, joint deterioration continues to be the most cited cause of premature pavement failure.  Improving joint construction, which in turn improves density and decreases permeability at the joint, is probably the single most important thing the asphalt industry can do to improve its pavements’ performance.

This webinar will cover the results of a recent project of longitudinal joints conducted by the Asphalt Institute and Federal Highway Administration that examined how longitudinal joints are specified and constructed across the United States.  The project included a review of literature, in-depth interviews with 19 paving experts, and site visits to various States.  A goal was to search for consensus on the best practices possible for achieving overall joint performance equal to that of the mat.  This 2-hour webinar will focus on those best practices or steps for constructing longitudinal joints, as well as contractor and agency considerations for improving longitudinal joint durability.   Uses of alternative non-traditional approaches on roadways are also covered.  Topics covered include:

  • Design and planning considerations
  • Density and permeability considerations
  • Butt versus notched wedge joints
  • Best paving lay-down and rolling practices
  • Equipment options
  • Alternative techniques and products

Who Should Attend
The webinar is targeted for: 1) paving contractors responsible for adopting and executing best practices, 2) inspectors responsible for the quality assurance of paving projects, 3) federal, state and local governments responsible for specifications and evaluating new technologies/products to improve overall longevity of asphalt pavements.
