Development of a Thickness Design System for Portland Cement Concrete Pavements
, 1983 This report covers the merger of criteria used in the Portland Cement Association\u27s and MSHTO\u27s pavement thickness design systems. The combined criteria is coupled with the principle of equal work as defined in classical physics to produce ...

Chemistry – A European Journal, EarlyView.Several γ$\gamma$‐belite(010)–water interfaces have been studied by molecular dynamics simulations using a high‐dimensional neural network potential. The structure and reactivity of interfacial water have been analyzed and two types of surface defects could be identified, which indicate the possible existence of a wide range of surface structures ...
