WebThe major factors affecting time available for compaction are (Roberts et al., 1996 [3] ): Initial mat temperature . Higher initial mat temperatures require more time to cool down to cessation temperature, thus increasing the time available for compaction. However, overheating the HMA will damage the asphalt binder and cause emissions. WebTypical values for theoretical maximum specific gravity range from approximately 2.400 to 2.700 depending on the aggregate specific gravity and asphalt binder content. Unusually light or heavy aggregates may result in a value outside this typical range. Calculations (Interactive Equation) Calculate and report Gmm to the nearest thousandth.
