Simple Abrasion Test Equipment for Evaluation of Abrasion Resistance of Pavement Concrete

Abstract

This paper discusses the utility of simple abrasion test equipment that was designed on the basis of Chinese National Standards GB/T 16926-1997, to measure the abrasion resistance of pavement concrete. Main characteristics of this equipment are smaller number of rotating balls, lower speed, and variable pressure (0-120N). To access the practicability of the equipment, abrasion tests were conducted on mortar and concrete specimens cured under different conditions and at different curing age. Results confirmed the performance and importance of measuring the abrasion resistance of pavement concrete by trundle abrasion method.
