STRENGTH EVALUATION OF PAVEMENT LAYERS BY DIFFERENT TESTING TECHNIQUES

This paper deals with the in-place evaluation of pavement layers using three different methods such as plate bearing tests, Benkelman beam deflection tests and vibration method based on wave propagation principle. The data pertaining to granular layers has been presented and analysed in this paper. Amongst the three methods deflection method using Benkelman beam is quicker and reliable whereas the wave propagation technique is suitable for quicker qualitative evaluation only. Good correlation is found to exist between elastic deflection from plate bearing tests and beam deflection tests. It has been observed that edyn values obtained from wave propagation technique are higher than the elastic moduli obtained from plate bearing tests. (Author/TRRL)
