Title: A Nondestructive Evaluation Method for Semirigid Base Cracking Condition
Accession Number: 01624310
Record Type: Component
Abstract: The cracking status and development trend of semi-rigid base course have significant influence on the reflective cracking in pavement overlay structure. Before the asphalt layer is milled and moved, the semi-rigid base cracking condition cannot be obtained through visual surveys. Therefore, this paper develops a nondestructive falling weight deflectometer (FWD)-based evaluation model to evaluate the semi-rigid base cracking condition. It is found that the normalized back-calculated base modulus and the semi-rigid base cracking condition was linear relationship on log-log coordinates, and the normalized back-calculated base modulus would be a reasonable indicator for the evaluation of semi-rigid base damage (cracking) condition. Based on the comparison of measured data and back-calculated modulus in 2 freeways, the evaluation criterion is given.
