Simulation on the MicroDeval test for the aggregate wear

Aug 20, 2018 · It was found that the MicroDeval abrasion value increased exponentially rather than linear growth with the increase of the rotation times. The CoreLok multifunction aggregate density test equipment was adopted to measure the aggregate apparent density. The modulus of elasticity and Poisson ratio were measured by uniaxial compression test.
