California Pavement Preservation Center

Pavement Preservation Academy

As part of the Senate Bill 1 (SB-1) funding through the California State University, CSU, Transportation Consortium headed up by Mineta Transportation Institute (MTI) in San Jose State University, the California Pavement Preservation Center (CP2C) is pleased to announce a certificate program in pavement preservation, via The Pavement Preservation Academy (PPA). The purpose of the program is to help state and local agencies improve the design and construction of pavement preservation treatments. The effort began in 2018 with the publication of technical manuals for chip seals, slurry surfacing, Cape seals, and thin hot mix overlays. The first PPA was held in March 2021; the second PPA was held in March 2022; the third PPA was held on April 3-7, 2023. The following is the fourth Academy registration site:
