Laboratory based performance evaluation of high content reclaimed asphalt pavement in hot mix


Author(s): Kefale Adefris, Dr. Avinash Mpotdar and Dr Sisay Demeku

Abstract: During maintenance, rehabilitation, or reconstruction operations removing existing asphalt pavement materials are common. This practice produces a large amount of reclaimed asphalt pavement (RAP), which contains valuable asphalt binder and aggregate. The road construction and maintenance works depend on the utilization of natural and industrial materials which is limited and scarce. As existing pavement diminishes, obtaining quarry sites is difficult.The objective of this study is to conduct laboratory based- research that investigates and evaluates the performance of hot mix asphalt mixtures containing different amounts of RAP for binder course construction.Quality test for all materials used in the mix was done separately. Marshall Parameter was done for control mix and mix containing RAP to evaluate the mechanical properties of the asphalt binder mixture containing RAP and control mix. To predict the field condition performance test such as moisture susceptibility, indirect tensile strength, and Humberg wheel tracking test was conducted.The obtained result for all mixes is in terms of Marshall Parameter criteria and the performance test proves that the asphalt binder course mix can be successfully produced using RAP material within the specification limit. The study concluded that, using RAP in HMA up to 40% is possible to design a mix that satisfied the required specification for Marshall Property and performance test with low cost than the control mix.
