Study of the relationship of asphalt modulus to the height of the laboratory LWD

Abstract

Abstract In the construction of the transportation network, road infrastructure is being developed intensively. Quality assurance is needed to prevent failure and ensure long performance. To measure the quality of road works, especially asphalt, can now use the laboratory version of the Lightweight deflectometer (LWD) tool developed by DGH. Lightweight deflectometer (LWD); which has been developed for evaluation of surface stiffness can be used to estimate the degree of compaction and produce modulus of elasticity. This a laboratory-based study aims to analyze the effect of asphalt mixture density (AC-WC) on deflection values and modulus of elasticity using laboratory version of the LWD and find the correlation between the modulus of elasticity of asphalt against variations in the height of the mashing load.
