Abstract

The measurement of dynamic strain of asphalt pavement helps to effectively reveal the real mechanical state within the pavement structure. In this paper, a three-direction strain measurement method at a single testing point, which is different from the traditional unilateral measurement at a single point, is proposed. Then, the in-situ layout scheme for Fiber Bragg Grating (FBG) strain sensors is presented, and the measured three-direction dynamic strain in different loading conditions are compared and analyzed. The results show that the three-direction strain measurement provides more useful information about the observable viscoelastic characteristics of asphalt pavement, and that the strain response of pavement varying with loading conditions basically decreases with the increase of vehicle speed. Some suggestions for the field strain measurement and its further development are finally offered in this paper.
