As part of the City’s Three Year Pavement Preservation and Rehabilitation Program, the City recently completed 6.8 miles of preservation utilizing an Ashpalt Rubber Aggregate Membrane (ARAM) technique. This method not only provides a cost effective way to extend the useful life of the street but also promotes recycling markets by utilizing a resurfacing product derived from waste tires generated in California.
The City of Riverside Public Works Department (City) acknowledges the Department of Resources Recycling and Recovery (CalRecycle) for providing a portion of the project funding through their Rubberized Pavement Grant Program.
The California Tire Recycling Act of 1989 and Senate Bill 876 enacted in 2000 require CalRecycle, to regulate and manage the 40 million reusable and waste tires generated in the state every year. To minimize the stockpiling and disposal of waste tires in landfills, CalRecycle offers grants of up to $250,000 through the grant program to local agencies for street rehabilitation projects that use a rubberized chip seal.
This project utilized the Calrecycle rubberized grant funds and the City’s local Gas Tax funds, on the following eight local streets within the City’s Green Belt. See the above location map for the locations of the streets indicated below. The final construction cost was $570,374.94 of which $92,700 was paid for by the CalRecycle Grant program.

The ARAM process applies a thick layer of
rubberized asphalt followed by a 3/8 inch
stone chip that is then covered with a
traditional slurry seal. Cost analysis
demonstrated that the ARAM method can reduce
rehabilitation cost by approximately 50%
while providing a superior membrane to
prevent oxidation and water infiltration. On
low volume roads, the ARAM is expected to
have a life span similar to a traditional
street resurfacing. See the above
photographs indicating the typical roadway
conditions of the existing roadways as well
as sample locations photographs of the
roadways after the application of the ARAM
The total number of tires utilized for the completion of the ARAM project is approximately 6,677, of which 100% of the tire rubber purchased and used in the project was from California. To find out more about RAC and the State's Recycling Programs, please check out the CalRecycle website.
