| 摘要： | This project evaluated the ability of interlayer systems used in HMA overlays to retard reflective cracking. Field crack surveys and forensic investigation, including video imaging and ground penetrating radar surveys as well as laboratory testing of cored specimens, were conducted to examine the behavior of reflective cracking and reflective cracking control systems applied in Illinois. Crack extent and severity were recorded at 24 locations across Illinois. The performance evaluation focused on five types of interlayer systems: area- and strip-type non-woven fabric; two strip-type composite; and a fine, high polymer content HMA interlayer system. Two reflective cracking indices were developed to characterize the condition of HMA overlays regarding reflective cracking as well as transverse cracking. In addition, a performance benefit ratio parameter, PBR, was developed to assess the performance of treated pavements relative to control sections. The study provided a quantitative assessment for various types of reflective cracking interlayer systems. In addition, it provides a means to predict the performance of several interlayer systems under various vehicular and environmental loading conditions through a simple ESALs-T(sub L)chart. A companion report (volume 2), PB2010-115003, provides tools for the selection of appropriate reflective crack control treatments based upon traffic, climate, and life cycle costs using a user-friendly life cycle cost analysis program (CIND: Cost-effective INnterlayer system Decision program). |
