Abstract

The purpose of this study is to evaluate the durability of anti-reflective cracking systems that have a geosynthetic, geotextile or SAMI layer in the interlayer zone. For this purpose, a dynamic test has been designed that simulates the passing of traffic loads on the road surface. Stresses are applied to a two-layer test piece, which represents the pavement structure, with an anti-crack reflection system between the lower part, which is to be reinforced, and the upper part, which is the new pavement. In the lower layer, a longitudinal groove has been made that simulates an initial crack. All interlayer systems delay crack reflection. The test procedure is sensitive to the kind of interlayer system and helps to determine the optimal dosage of tack coat. Moreover, it has been verified that geogrids show higher resistance to repeated loading cycles, and geogrids with a higher stiffness modulus show better behaviour.
