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.

Young’s modulus of graphene: A molecular dynamics study [PDF]
Physical Review B, 2009 The Young's modulus of graphene is investigated through the intrinsic thermal vibration in graphene which is `observed' by molecular dynamics, and the results agree quite well with the recent experiment [Science \textbf{321}, 385 (2008)]. This method is further applied to show that the Young's modulus of graphene: 1.
