Presentation on the use of Cold-in-Place asphalt recycling in the City of Corona, Calif. Presentation delivered at the CalAPA Spring Asphalt Pavement Conference, held March 20-21, 2019 in Ontario, CA.

1. City of Corona
Cold-in-Place Recycling Project
Location: Ontario Avenue from California Avenue to Magnolia Avenue
Description: The Ontario Avenue Street Improvements consisted of the
rehabilitation of Ontario Avenue using a Cold-In-Place Recycling
(CIR) method from Magnolia Avenue to California Avenue. The
project recycled the top 3 inches of existing asphalt surface, mixed the
crushed asphalt with an asphalt recycling agent, and placed it back
down with a paver. Other ancillary improvements included minor
Americans with Disability Act (ADA) upgrades to the existing concrete
improvements, traffic signal modifications, and thermoplastic street
striping.
Schedule: Construction started in May 2018 and was completed in
November 2018.
Project Cost: $ 1,500,617.41
Funding: Measure A, Gas Tax, and Public Works Transportation Grant

The long road segments and busy commercial centers made CIR
an ideal alternative to conventional grinding and an AC overlay

Replacing 3” of pavement while maintaining traffic would have
been very difficult adjacent to busy commercial centers
