Influence of aggregate packing structure and bitumen-aggregate binding characteristic on the mechanistic performance of hot-mix asphalt concrete

Numerous trials and samples were conducted in the selection of a favourable aggregate blend for a Hot-Mix Asphalt (HMA) which is a time consuming process. Hence, a method was developed as a tool to effectively analyse and evaluate HMA in the laboratory and relate it to the field performance. Aggrega...
