Abstract:

The Louisiana Department of Transportation and Development (DOTD) revised its asphalt pavement specifications based upon research conducted at the Louisiana Transportation Research Center (LTRC). These changes introduced performance-based specifications in the form of the semi-circular bending (SCB) and the loaded wheel tracking (LWT) tests. Additionally, there were revisions made to the volumetric and compaction criteria during the pavement design process. The intent of this research was to analyze and compare the performance of asphalt pavements constructed using specifications from the 2006 specifications to pavements built with the 2016 specifications. The project evaluated the density, volumetric, and performance data for various pavement sections. The research found that the new mixtures passed the performance-based criteria as well as the volumetric criteria, and the new specifications enhanced field rutting and cracking performance and have the potential to increase pavement service life by one to three years.
