Characterization and Best Use of Recycled Asphalt Shingles in

Recycled asphalt shingles (RAS) often containing more than 20 percent asphalt binder has become another black gold in the asphalt industry. There are two basic types of RAS scraps in the market: tear-off asphalt shingles (TOAS) and manufacture waste asphalt shingles (MWAS). Both TOAS and MWAS have been used in hot-mix asphalt (HMA) paving in Texas.

Methods of Rehabilitating Pavements with Moisture Damaged Asphalt

Moisture damage to old hot mix asphalt layers can result in surface cracking and greatly reduce the life of any new asphalt overlay. Buried moisture damage, generally called stripping, in asphalt layers can often go undetected, resulting in new overlays not reaching their design life. Conventional wisdom is to mill down to solid HMA and then place full depth new HMA. This strategy is costly and means that …

Chapter V – Recycling

4. Historical development of hot mix asphalt recycling (Batch Plants) In most countries, the development of hot mix asphalt recycling started after the energy crisis in 1973. Recycling was limited to a maximum of 15 to 20% RA. In this partial recycling process the RA was added cold, into the batch plant mixer, filled with overheated virgin materials.
