A long-standing challenge in keeping an asphalt pavement from reaching its potential life is its longitudinal joints. Premature joint failures are the result of a combination of low density, permeability, segregation and lack of adhesion at the interface. Improving this component of our flexible pavement systems is one of the most important things we can do to improve performance.
Below is a list of downloadable products/documents covering longitudinal joints, including a webinar recording on Best Practices for Longitudinal Joints.
