Project Summary/Scope:

One of the challenges facing municipalities is improving the quality and reliability of local streets while minimizing the amount of costly and aggravating maintenance and repair. Dana Point has become the leader in the adoption and use of innovative materials and technologies that enhance the performance of local roads and streets.

The city’s goal was to exceed a PCI rating of 80 on all streets. Since 2010, the City of Dana Point has utilized a pavement interlayer, the GlasPave paving mat, great success. The interlayer provides waterproofing capabilities and extends the crack-free life of asphalt roadways up to six-times longer by adding consistent, uniform high-strength tensile elements to asphalt pavements.

To date, the City has added GlasPave paving mats to 86 streets, arterial and collector roads and local highways. This has reduced asphalt cracking, extended maintenance cycles and improved roadway surfaces and ride quality. The has also resulted in an improvement to the overall safety of local commuters. The use of pavement interlayers have helped Dana Point achieve a Good Pavement Condition Index (PCI 71-100) from the 2016 California Statewide Local Streets and Roads Needs Assessment report, far exceeding the Statewide average.
