Asphalt Rubber Chip Sealing Technology Transfer

Technology Transfer| Concrete Construction Magazine

In 1964, Phoenix began using rubberized asphalt and gravel as a chip seal for city streets. Though successful in preserving the pavement, the program was discontinued in 1989 because of potential damage to cars by loose gravel. So the city began using an asphalt rubber hot mix to add a 1-inch overlay to streets.

These projects will include reacted rubber for both the hot rubber chip seal (HRCS) and in the hot rubber thin overlay (HRTO) based on the research development. The HRCS is an innovative technology with capability the to maximize the pavement service life in relative high traffic volume roads. This type of chip seal will use over 30% of edreact rubber in the asphalt emulsion, instead of …

CHIP SEAL - cttp

A chip seal is a surface treatment that can be applied to a paved surface or primed based course. For this treatment, a rapid setting asphalt emulsion or other bituminous material is sprayed onto the roadway surface, and then immediately covered by a layer of mineral aggregate.

Asphalt Seal-Coat Treatments

Asphalt seal coats are surface treatments designed to seal and protect the asphalt pavement from harmful environmental conditions such as sunlight, rain, and snow. Surface treatments are also applied to enhance the wearing properties and improve the traction between the pavement and vehicle tires.

Asphalt Crack Filling and Sealing | Crack Filling

Sealcoating and crack filling is a fraction of the cost of repairing or replacing asphalt pavement. The key to effective crack filling and sealing is to repair and fill the cracks while they are small, as crack filling inhibits crack growth and keeps new cracks from forming.


1. Loose stones shortly after application could crack windshields. Utilization of the rubber application drastically reduces this possibility as the chip seal can be swept in as little as 1 hour with a 10% minimum rubber chip seal.
