Study on the Method of Pavement Quality Test and Device Design

Abstract

This paper presents a practical method for engineering test on the base of mechanical eccentricity principle, and a new vibration test equipment for testing the quality of pavement is designed. A sensor was installed on the exciting bar for measuring the exciting force and frequency which generated by the equipment. The mechanical performance could be detected according to the deformation of object. The equipment has the merits such as small volume, light weight and compact conformation. It can be used not only in laboratorybut also in field and has great practical value.
