Laboratory Investigation on utilization of maximum percentage of Reclaimed Asphalt pavement material in Bituminous concrete mix (BC Grading-1) with VG-30 Grade bitumen.
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 9
Abstract
RAP is old bituminous pavement that is milled up or ripped off the roadway . This material can be reused in new bituminous mixtures because the components of the mix (the bitumen binder and aggregate) still have value. The main objective of this study aims to determine the maximum amount of reclaimed asphalt pavement material percent that can be used in BC mix with Virgin VG-30 Grade bitumen. The present laboratory investigation carried out on Bituminous Concrete (BC) mixes prepared with control mix with virgin material, and Mixes with variable % of RAP from 10 % to 80% with VG-30 Grade bitumen. The experimental process involves determination of characteristics of the materials procured. All the characteristics were found to be within specified specifications as per MoRT&H and IS standards. Firstly, the quantity of RAP and virgin aggregates are to be blended in such a way that the resultant gradation of aggregates conforms to the BC Grading-1 as per MoRT&H. The optimum Bitumen content is the percentage of bitumen corresponding to 4% of Air Voids was determined from Marshal graphs. Volumetric analysis, Marshall Stability, flow and water sensitivity tests were carried out on the specimens prepared at OBC in all mixes. Inclusion of maximum upto30% of RAP in BC with VG-30 Grade bitumen was found to be suitable for construction and rehabilitation of flexible pavement, without compromising specifications and standards as specified.
