Asphalt-Rubber Binder Laboratory Performance
Three experimental test roads containing asphalt-rubber interlayers were constructed. Test pavements were designed as statistical experiments such that future performance analysis could be obtained. Precondition surveys were conducted prior to rehabilitation to provide documentation for future condition surveys. Samples of asphalt-rubber were obtained during field mixing of asphalt and rubber for laboratory characterization. Samples of asphalt and rubber were obtained for mixing in the laboratory. A comparison was made between laboratory test results of field and laboratory prepared asphalt-rubber. Three new laboratory tests were used to evaluate asphalt-rubber engineering properties. These included force ductility, double ball softening point, and torque fork viscosity. Results of these laboratory tests indicate engineering properties of field prepared asphalt-rubber can be duplicated by laboratory prepared mixtures. This means future mixtures of asphalt-rubber can be designed in the laboratory prior to construction.
