ABSTRACT RAP (reclaimed asphalt pavement) produced from the reconstruction of asphalt road pavements is one of the alternative material proposed. Rap can be used as an alternative material for both fine and coarse aggregate, it is conventionally used as coarse aggregate in asphalt pavement. In this experimental study, Performance of Pavement Quality Cement Concrete(PQCC) is studied when virgin aggregates are replaced by RAP by conducting experimental study in laboratory and also performing numerical analysis on RAP concrete model cube by using ANSYS to find out stress value at different percentage of RAP and age of concrete under loading. Fine aggregate is replaced with RAP by 0%, 15%, 30%, 45%, 60% and Coarse aggregate with RAP by 0%, 15%, 30%, 45%, and 60%.Experimental results are validated with numerical results. It is observed that RAP will reduce the performance of concrete and affects mechanical properties of concrete like compressive and flexural strength, density on increasing the percentage in concrete. But for 15 % replacement, RAP concrete has fulfilled the requirements of M30 concrete and for 30%replacement compressive strength of concrete is 28.456 N/mm² which is very near to the minimum strength value of M30 concrete. For all mix proportion of concrete flexural strength is more than minimum required strength of M30 concrete. The results indicated that RAP can be used as an aggregate in PQCC up to limited percentage. Key words: RAP, ANSYS, PQCC, M30 concrete.

INTRODUCTION Recycling of asphalt pavements is one of the most effective and proved and also approved recycling processes. It has been organized and being used successfully for rehabilitation processes in many countries across the globe. The reuse of removed asphalt pavement in India has not given more importance in 20thcentury, because of the poor economic conditions and lack of updated, new technologies. The cost of
