Reclaimed asphalt pavement (RAP) can be used as granular base or subbase material in virtually all pavement types, including paved and unpaved roadways, parking areas, bicycle paths, gravel road rehabilitation, shoulders, residential driveways, trench backfill, engineered fill, pipe bedding, and culvert backfill.
The workability of mixes made with RCA can be improved by limiting the use of recycled fine aggregate, adding fly as a partial cement replacement and using water reducing agents. Limiting the amount of recycled fine aggregate also improves the durability and strength of concrete made with RCA.
Screening in aggregates production. The crushers are the muscle in the process, but the screens are the brains of the rock processing circuit. Crushing equipment selection is often carefully considered due to high capital and operating costs, but because screens control the product quality and specifiions, they have a very large impact on a plant''s profitability.
