Best Practices for Asphalt Longitudinal Joints Asphalt

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

FHWA and AI release longitudinal joints best practices

FHWA and AI release longitudinal joints best practices. By Mark Buncher, Ph.D., P.E. A long-standing challenge in keeping an asphalt pavement from reaching its potential life is its longitudinal joints. Debate, research, opinion and innovation have all had their place in getting us to where we are today.

Longitudinal Joint Information Asphalt

With the overall goal being to improve longitudinal joint performance nationwide, the Federal Highway Administration FHWA and the Asphalt Institute recently completed an effort to review past studies and research and to examine current state-of-the-practice for both specifying and constructing longitudinal joints.

Best Practices for Longitudinal Joint Construction

Clemson University has released a report that evaluates different joint construction techniques used in South Carolina to compare the effects of multiple variables on the quality and performance of longitudinal joints. Joints are the weakest area of an asphalt pavement and longitudinal joint cracking occurs for a number of reasons that lead to low density, low indirect tensile strength,
