Abstract: This paper discusses the results obtained from small scale accelerated pavement testing in the laboratory. The small scale loading equipment has been used in the laboratory to perform fatigue tests on HMA test slabs compacted using vibratory compactor in the laboratory. The real time analysis of data obtained from strain gauges and thermocouples indicated the effect of loading and temperature on the strain response. The fatigue characteristic equation has been developed and compared with the standard fatigue equation.
