Asphalt Pavement Thickness and Mix Design - Asphalt ...

Mix temperature is dependent on the grade of asphalt used in the mix. Less viscous the asphalt requires lower the temperatures, while more viscous asphalt requires higher temperatures.At the start of a mix design project, target temperatures are specified for proper mixing and compaction.

Effects of Asphalt Mix Design Properties on Pavement ...

2016-7-4 · The main objective of this study was to investigate the effects of hot mix asphalt material properties on the performance of flexible pavements via mechanistic approach. 3D Move Analysis software was utilized to determine rutting and cracking distresses in an asphalt concrete (AC) layer. Fourteen different Superpave mixes were evaluated by utilizing results of the Dynamic Modulus Test …
