Abstract: The size of an asphalt concrete test specimen has been traditionally determined based on experience and practical purposes. This study discusses theoretical considerations for selecting the minimum dimensions so that the ...

Abstract: The performance of asphalt concrete (AC) mixtures is influenced by the arrangement of aggregates and their associated air voids. Parameters to measure aggregate orientation, aggregate gradation, and air void distribution ...

Abstract: This study describes experimental and analytical methods to quantify the structure of air voids in asphalt mixes. An x-ray computed tomography system along with image analysis techniques were used to measure air void sizes ...
