Abstract:

In recent years, asphalt pavements built with acceptable levels of quality required in the Louisiana Standard Specifications for Roads and Bridges have started to experience premature failures more frequently than before. Primary causes of the frequent premature failures can be attributed to the increased traffic volume on highways. Adaptation of unconventional asphalt paving technologies, such as the use of high percentage recycling materials, polymer modified asphalt cements, warm-mix asphalt technologies, etc., can also make it challenging to adequately guarantee the longterm performance of pavements with conventional quality requirements such as voids filled with asphalt (VFA), air voids (AV), roadway density, international roughness index (IRI), etc. Coupled with the rapid decline of experienced QC/QA personnel, this lack of effective QC/QA methodologies pose a tremendous challenge to ensure long-term performance of asphalt pavement in Louisiana.
