Evaluation of Fabric Interlayers - A Condition Survey Report

摘要

Field installations consisting of eight to thirteen 1/4-mile pavement test sections in districts 4, 7, 10 and 21 were constructed in 1979-80. The purpose of these pavements was to evaluate fabric interlayers. Research Report 261-2, published in 1982, presented the initial field evaluation and properties of the construction materials. The supplement gives a field evaluation after up to five years in service. Based on the data collected, there is no evidence to indicate that one fabric performs better than another or that any fabric performs better than none at all in reducing reflection cracking.
