Field Verification of Superpave Dynamic Modulus [PDF]

Journal of Materials in Civil Engineering, 2010
In the mechanistic-empirical pavement design guide, prediction of flexible pavement response and performance needs an input of dynamic modulus of hot-mix asphalt at all three levels of hierarchical inputs. This study was intended to find the best way to predict/derive this input.

Rutting as a Function of Dynamic Modulus and Gradation [PDF]

Journal of Materials in Civil Engineering, 2011
This study was conducted to investigate rutting resistance of asphalt concrete (AC) mixtures as a function of dynamic modulus and gradation. The Flow number (FN) test, the (NCHRP 9-19) recommended procedure for evaluating rutting resistance of AC mixtures, was used to simulate rutting in the laboratory.
