Parametric characterization of semi-rigid asphalt skeleton using recycled materials

Concrete Pavement with significantly good resistance to wear and tear is expensive while asphalt pavement can easily be constructed and repaired but is not durable. In considerations to cost-benefit, modification in pavement construction plays a vibrant role. Exploration in semi-rigid pavement construction is getting common. This paper signifies the viable solutions of similar pavement using recycled materials. The methodology is based on detailed analysis of laboratory experimentations within the combinations of fresh aggregates, Reclaimed Asphalt Pavement (RAP) and Construction waste (CW). Focusing blend grading, clear differences are obtained between the stabilities of grouted and un-grouted samples. Likewise in the case of 100% RAP with minimum air voids and curing time, about 300% increase in stability observed in grouted sample. The paper corresponds to save the cost of 100% fresh aggregates identifying the need of the research. Possible combinations of RAP and CW reveal the passing of certain limits through grouting.
