PDF Characterization and Best Use of Recycled Asphalt Shingles

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.

Save Money By Using Recycled Asphalt

Laying Down Recycled Asphalt as a New Asphalt Surface Area. Using recycled asphalt is a cost-saving alternative to using new asphalt, and many asphalt professionals are now offering it as an option. Here are two things you need to know before you buy. The biggest concern about recycled asphalt is whether or not it is as durable as new asphalt.

How to Lay Recycled Asphalt | Hunker

The recycled asphalt will be laid down just like a traditional gravel driveway and should stand up well for a few years. Step 4 Roll over the asphalt layer with a steam roller. The steam roller will further compress and heat the recycled asphalt so it essentially melts together and then sets up to form a hardened surface as durable as new asphalt.
