Van de Ven, M.F.C. Wu, S.P. Woldekidan, M.F. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2012-05-23 Abstract Thin surfaces are specially designed to provide significant additional surface properties to pavements without affecting other qualities of the surface such as ride quality and durability. In addition to economic benefits, thin surfaces can protect pavements against deterioration caused by traffic and weather. One of the most important properties of thin surfaces is their adhesion to the substrate layer. In order to avoid bond failure and/or slippage between the thin surface and the pavement layer, a strong adhesive strength is required. Different equipment and methods, such as a Torque Bond test and the UTEP (University of Texas at El Paso) Pull-Off test, are used to determine this adhesive strength. However, these bonding tests have no loading speed control system and are not easily to be placed in a climate room for a constant temperature test. An advanced pull test method was designed and introduced in this paper for determine the adhesive strength at the interface between a thin surface layer and the substrate layer. In a climate chamber, a displacement/force controlled test was developed, in which the load-displacement curve till failure can be measured. The possible failure paths in the thin surface, at the interface between thin surface and in the asphalt mixture layer below are discussed. A Finite Element Model (FEM) was used to simulate the boundary effect due to the different sample preparation procedures, which includes with and without cut through thin surfaces into asphalt layer. Test results indicate that this advanced pull test can be used to determine the adhesion strength at the interface between the thin surface layer and substrate layer.
