Crushing is used to break apart large RAP particles. Screening prevents overly large RAP conglomerations from entering the plant-mixing process. How much RAP can I use? The amount of RAP you can use in a mixture depends on local/VDOT specifications, the quality of RAP, the design of the asphalt plant and availability of RAP.
Recycled Asphalt Driveway Pros. Many homeowners have fallen in love with their recycled asphalt driveways.

Sep 28, 2010 · Commercial Asphalt tested the new RAS and said it noticed no difference in the mix. Large quantities of ground asphalt were placed on conveyor belts and carried into the plant and mixed with HMA. Kuehborn believes the time is now for MnDOT to consider using asphalt shingle scrap.
4/17/2019 · Recycled Asphalt Shingles. Using recycled asphalt shingles has several benefits in the production of Hot-Mix Asphalt (HMA). By reusing asphalt from shingles, asphalt manufacturers can reduce costs and improve the quality of asphalt pavement. Using recycled shingles provides a source of aggregate, which reduces the need for mined aggregate.
Asphalt made partly of recycled plastic bags has already been trialled successfully in Victoria and Sydney but it is yet to be widely used. Downer General Manager Pavements Stuart Billing said the new plant would have the capability to use “significant quantities” of recycled materials.
The asphalt cement in the shingles is usually air-blown and is substantially harder than the normal asphalt binder used in a standard HMA mix. So the HMA plant operator may use softer asphalt, such as a PG58-28 versus a PG64-22, to offset the harder asphalt contained in the shingles.
