LABORATORY TESTING OF FABRIC INTERLAYERS FOR ASPHALT CONCRETE PAVING: INTERIM REPORT

Because of the proliferation of paving products being presented as reflection crack retarders, the need developed for laboratory tests that can be used as a screening device to avoid the extensive costs and delays associated with full-scale field tests of all of these products. This need resulted in an FHWA-financed research project to generate laboratory tests for estimating the effect of various fabric interlayers on asphalt concrete (AC) overlay properties such as (a) water permeability, (b) susceptibility to flexural fatigue reflection cracking, (c) susceptibility to vertical shear fatigue reflection cracking, and (d) to horizontal shear failure (slipping). Testing was also done to characterize popular fabrics in terms of physical and mechanical properties such as tensile strength, elongation, modulus, weight, thickness, and heat resistance. Possible correlations between these fabric properties and the above four overlay properties were investigated. In addition, methods for estimating the optimum asphalt tackcoat application rate for fabrics were developed. These research efforts have led to a more educated and selective use of fabrics in AC paving. (Author)
