Abstract A new strength test method for asphalt mixture at low temperature is presented in this paper. The method uses a modified Bending Beam Rheometer (BBR), capable of applying loads at different rates. Two major factors that can significantly affect strength were analyzed: cooling medium and specimen size.

For AC-13 (SBS) asphalt mixture used in this test, the change of strength with temperature has obvious stages. The inflection point of the strength change with temperature is 40°C. In the range of 5–40°C, the strength decreases rapidly with temperature, and the relationship between them is linear.

Asphalt Mixture typically weighs from 142 to 148 pounds per cubic foot (PCF) in-place. Use 148 PCF. Calculate the tonnage needed. (remember to convert from pounds to tons; 2000 pounds per ton). 83.3 cubic feet x 148 PCF = 12328 pounds of mix = …

 · Additionally, Meocci et al. [] noted that the commonly used accelerated curing process (72 h at 40°C) did not allow the definitive mixture strength and stiffness to be reached, obtaining higher values after 10 days, a behavior that should also be evaluated in this research with a variation in the curing time.The same authors also observed an …
