| 摘要： | In 2001, the Wisconsin Department of Transportation (WisDOT) initiated this Federal Experimental Project to evaluate the effectiveness of Strata Reflective Crack Relief System, an interlayer designed to delay cracks from reflecting through hot mix asphalt (HMA) overlays placed on concrete pavements. Test sections were constructed in Racine County in 2001 and in St. Croix County in 2002. After the existing HMA pavements were milled off, the existing underlying concrete pavement was repaired. A tack coat was applied prior to paving a one-inch thick Strata interlayer. The interlayer was then overlaid with HMA. Crack surveys were conducted annually for several years. The results from the Racine County project showed that the Strata interlayer delayed reflective cracking in an HMA overlay, over a concrete pavement with doweled full-depth patches, for two years. However, there was no conclusive evidence that Strata would reduce reflective cracking longer than two years. / NOTE: Final rept. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
