Abstract

The recognition of vehicle load in motion has always been an important problem to be solved in pavement. In this paper, an improved fiber Bragg grating (FBG) based sensor has been developed to measure the vehicle load transferred pressure in the asphalt pavement structures. Cyclic loading tests have been conducted to calibrate the structural and sensing properties of the FBG sensors. The proposed sensors have been further used in ZhangBian highway to measure the vehicle load induced pressures in asphalt pavement. The results indicate that the improved sensors own high survival rate to resist the harsh construction condition in pavements and the quick recovery speed validates the feasibility of the proposed sensors to recognize the vehicle load in motion.
