Abstract

In the past extensive testing was performed at BRRC to determine the laboratory performance of anti-cracking interfaces in case of stresses induced by thermal variations. Several experimental sites were followed during that period to set up correct laying procedures for the different types of products and to give recommendations when applying these products. Recently this study was completed by a four year research project. Important objectives of this project were: the setup of a new test to simulate the vertical movements induced by traffic on overlaid cement concrete slabs, the evaluation of the performance of different anti-cracking interface systems with this new test and the validation of these results by experimental field trials. In this article this new laboratory test to simulate the vertical movement is described in detail and the performances of a reference and four types of anti-cracking interface systems, being a stress absorbing membrane interlayer (SAMI), a geogrid, a geocomposite and a steel reinforcing netting, are compared.
