Determination of coefficient of thermal contraction of asphalt concrete using indirect tensile test hardware

摘要

The indirect tension(IDT)test, as developed during the Strategic Highway Research Program(SHRP)is a technique or determining the Creep compliance and strength of asphalt concrete mixtures in tension. These data can be used in thermo-viscoelastic analysis to evaluate the ability of the mixture to resist thermal cracking in a given application. An essential piece of information in performing the calculation of Thermal stress using IDT creep data is the coefficient of thermal Contraction(α)of the mixture.
