Abstract:

Reflective cracking due to shrinkage and brittleness in asphalt pavements can seriously degrade an asphalt overlay ; before it is near the end of its design life. Geosynthetics have been used to impede the reflection of existing ; transverse cracking to the new overlay. The geosynthetics are intended to minimize the tension transferred to the ; overlay from the existing pavement. The Oregon Department of Transportation (ODOT) installed a test section ; consisting of 98 transverse cracks treated with five different geosynthetic types, 22 transverse cracks treated with ; crack filling only and a control section of 20 untreated transverse cracks. ; The test and control sections were monitored from 1999 to 2007. Each of the 140 test sites were revisited once each ; year to determine if the cracks had reflected, and if they had, measure their length and width. At the end of the study ; comparisons were made to determine if the geosynthetic materials were effective at controlling (by preventing or ; lessening the return of) reflective cracking.
