Abstract: Graphene oxide (GO) has the potential to increase the service life of asphalt binders and asphalt mixtures, but there are concerns about its high cost. The purpose of this work is to provide a methodology to perform a ...

Abstract: The light weight deflectometer (LWD) is a portable, nondestructive testing device that can estimate pavement layer parameters, namely moduli. Conventional backcalculation of layer parameters from LWD deflections is formulated ...

Abstract: The lightweight deflectometer (LWD) is a portable device that measures surface deflections and applied force, from which dynamic stiffness and elastic modulus can be estimated. The inclusion of radial offset sensors with ...

Abstract: This paper presents results of structural analyses and a preliminary design of a precast, prestressed concrete lunar base subjected to one atmosphere internal pressure. The proposed infrastructure measures 120 ft in diameter ...
