沥青层反算模量的温度修正系数
Temperature Adjustment Factor for Backcalculated Modulus of Asphalt Pavement Layer
摘要
Abstract
Falling weight deflectometer (FWD) tests were conducted at the pavements in Shanghai. The collected data were used to back-calculate the modulus of asphalt pavement layer. There was a good exponential relationship between the pavement layer modulus and the asphalt layer temperature. The equation of temperature and modulus was developed for the pavements in Shanghai. The temperature adjustment factors were proposed to correct the back-calculated modulus at any temperature to reference temperature modulus. Comparisons were made between the temperature corrected modulus and indoor and outdoor modulus. Results indicate that the temperature adjustment factor is of a high degree of reliability.关键词
