Project Description
The City of Orinda needed to fix their failed pavements (PCI=41) with a sustainable and smart process. It was a big project with 92.7 miles of pavement. The City passed measures J & L that allowed the program to be funded. The next step was to implement the best and most sustainable technology available to fix their roads. The only solution was Full Depth Reclamation (FDR). FDR pulverizes the existing pavement section, then adds cement, water and recompacts the stabilized section into a perfect base section. It’s stronger and essentially impermeable to water intrusion. The finished product is a perpetual pavement section that only needs the wearing surfaced maintained. No need for new aggregates along with no trucking out the old material makes FDR the fastest growing process for rebuilding failed roads. FDR projects reduce energy consumption by 28% and GHG reduction by 48% on average. The City of Orinda’s Pavement Rehabilitation Program, funded by it’s own residents through Measure J & L performed complete reconstruction of 63 failed residential roads (11.4 lane miles) in 2017. FDR is the sustainable recycling of the existing pavement and road section that provides immediate benefits as well as future advantages during the road lifecycle. Never before has a Bay Area public agency undertook such an aggressive road rehabilitation program using FDR. The City of Orinda has a network of 92.7 miles of paved roads, most of which have been constructed over the past 50 plus years. The FDR reconstruction will raise the PCI rating of Orinda’s road from 41 to 88 in 2019 using sustainable technology.
