Seismic Pavement Analyzer and a portable version of it have been extensively used for quality control and monitoring the structural condition of pavements. With them, a pavement can be tested at closely spaced points and at a fraction of the cost and time of coring. The main tests used are the impact echo for determining the thickness of the slab, ultrasonic body wave and ultrasonic surface wave for determining the moduli of top layer, impulse response for determining the condition of subgrade, and SASW method for determining the modulus profile of pavement. Based on extensive field testing on numerous types of base and subgrade,the techniques in general, and the two devices in particular are quite suitable for many quality and pavement evaluation projects.
