Abstract: During the last two decades, several test methods and performance-based test specifications have been developed to select asphalt binders for use under different traffic and environmental conditions. The test equipment and ...

Abstract: A field and laboratory study was carried out to study the effect of pressure and temperature on the compaction of asphalt pavements. Density, temperature, number of passes, and type of roller were recorded in the field at ...

Abstract: During the last two decades, several research efforts have focused on the thermal cracking behavior of asphalt binders. Recently, important low-temperature cracking models have been introduced to include the failure ...

Abstract: Most of the techniques used today to evaluate practically moisture damage in asphalt pavements are involved in compacted asphalt mixtures. These tests generally simulate field conditions, and provide a performance-related ...

Abstract: The objective of this study is to experimentally and theoretically estimate the strain distribution in an asphalt binder as it exists in hot mix asphalt (HMA). This is important to evaluate whether the strain magnitudes ...

Abstract: Current Superpave performance grade (PG) grading specification utilizes a dynamic shear rheometer (DSR) at a gap height of 1-mm to determine the high-temperature performance grade of asphalt binders. It has been anticipated ...
