![]() So, the engineers are forced to use the available waste materials like recycled asphalt pavement (RAP) through proper processing in pavement construction. There is a shortage for the available of natural resources of virgin aggregates for the construction. The laboratory results indicate that the bituminous mixes with RAP and recycling agent provide better performance compared to virgin mixes.Ī good road network infrastructure is required due to increased urbanization. This paper presents the results of performance tests carried out on bituminous mixes with RAP and virgin mixes and their result. Various performance tests such as Retained Stability, Indirect Tensile Strength (ITS) and Tensile Strength Ratio (TSR), Resilient Modulus test has been carried out to compare the performance of RAP modified mixes and virgin mixes. The paper describes the comparison of properties of mixture with recycling agents, which has been prepared in laboratory and commercially available on the RAP material, and their performance has been compared with virgin mixes. Recycling agent has also been used in this study and the dosage of the recycling agent has been found as 10% by the weight of the bitumen present in RAP. In the present study, RAP samples have been collected and laboratory studies have been carried out to optimize the percentage of usable RAP. Therefore, restoration of physico-chemical deficiencies of oxidized bitumen by incorporation of appropriate dose of recycling agent is essential for desired performance of pavement. ![]() Napthene aromatics are converted to polar aromatics and these in turn to asphaltenes those are responsible for brittleness of bitumen in Recycled Asphalt Pavement (RAP). During the aging process, its composition changes with passage of time. The composition of bitumen plays a vital role in deciding durability of bituminous roads. ![]()
