FACTORS IN PAVING FABRIC FAILURES

This paper examines the findings of sixty-five investigations into the unsatisfactory performance of pavements containing paving fabric interlayer systems. The investigations were performed over a period of more than 15 years on projects scattered across the United States. Based on the results of the failure investigations, a variety of factors are examined for their impact on the performance of the paving fabric system. Paving fabric installation reports are also evaluated to give additional insights into the causes of failures and areas for careful monitoring during installation. Based on the results of the investigations several common characteristics can be observed. The most significant factor found to affect the performance of the system is the amount and uniformity of asphalt tack coat used in installation. Based on the findings of the complaint investigations examined, conclusions are made and recommendations are given on issues requiring attention both during installation and for future research.
