Abstract Recycling road making material has the potential to save money, energy and scarce resources; these advantages can be realised provided the in-service performance of recycled material is similar to that of comparable new material, in this Report the performance and cost of in-situ wearing course replacement by the Repave and Remix processes have been investigated and information is. Mix Development Wearing Course Basecourse trials using recycled glass have been undertaken previously in Ireland, therefore it was decided to investigate another use and try a finer glass as a sand replacement in a wearing course mix. Skid resistance was not considered a problem as pre-coated chippings will be rolled into the surface. Praticò FG et al. studied about permeable wearing courses from recycling reclaimed asphalt pavement for low-volume roads. They focused on obtaining permeable pavements by recycling high .

Nikolaides, E. Manthos. James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, Reclaimed Asphalt Pavement. The use of reclaimed asphalt pavement (also known as recycled asphalt pavement, RAP) material is increasing as local, state, and federal transportation agencies make more efficient use of their material is generated when old, damaged pavement materials are .

Owing to the shift in road construction activities from new construction to maintenance construction measures, the need for asphalt base courses will continue to fall and, as a result, recycling for the purpose of obtai-ning asphalt binder course and asphalt wearing course mixtures will increase in. Permeable Wearing Courses from Recycling Reclaimed Asphalt Pavement for Low-Volume Roads: Optimization Procedures. The recycling of reclaimed asphalt pavement (RAP) in hot-mix asphalt (HMA) is an important opportunity in regard to transportation infrastructure construction and maintenance because it helps to achieve more sustainable road transport systems (reduction of waste production . The current research involves: multiple recycling, how many times can an asphalt mix be recycled?: Does the old oxidized and hardened asphalt remain "mobilizable" in the form of a binder, (adhesion, elasticity, cohesion)? It is an inert material or not? For the wearing courses does the agreggate retain the friction/adhesion properties?
