摘要

Recycling is the running trend through all over the world. To save money and keep environment pollution free recycling of waste materials is the best way. Reclaimed Asphalt Pavement (RAP) is such type of waste materials, which are obtained huge amount from spoiled pavement. During this investigation an attempt is made to study the behavior of RAP materials for reuse in road construction. Aggregate Crushing Value, Aggregate Impact Value, Loss Angeles Abrasion Value and Ten percent fine value tests are also performed to determine the strength properties of coarse aggregate. Standard Marshall Mix Design procedure is followed in the design and testing of those mixes. The study reveals that untreated RAP materials are not good as a bituminous mix, but it can be acceptable with additional 1% bitumen content for use in the surface course of bituminous pavement. The investigation also indicates the possibility of adding coarse aggregate from RAP materials in the bituminous mixes with fresh aggregates, which gives satisfactory results. In our Indian subcontinent like Bangladesh, the rate of using RAP materials is very low. For that reason, the findings of the study will help in the development of sustainable road infrastructure for recycling in Indian Subcontinent.
