Project Description

The County of Riverside recently completed a 9.25-mile resurfacing project along Ramona Expressway between Rider St and Warren Road. The project used various treatment strategies which were efficient and sustainable to help restore or extend the life of the existing pavement.

The first treatment used was a direct overlay between Rider St and Lakeview Ave, with only the severely distressed areas receiving a localized dig out. The second treatment occurred between Lakeview Ave and 5th St and between 0.5 miles west of Warren Rd to Warren Rd and consisted of pulverizing the existing asphalt and reusing it as a cement-stabilized base before overlaying with new HMA. The final treatment was a microsurface between 5th St and 0.5 miles west of Warren Rd.

The cement-stabilized base, which reused pulverized grinding, was highly efficient and sustainable. Through this treatment option, the project could reuse existing asphalt material already on site and turn it into a new base material. The cement-stabilized base provided the added benefit of being a sturdy driveable surface shortly after applying the cement, which was a critical factor for this highly used commuter route.

In addition to the various pavement strategies, the project also installed spring-loaded channelizers between a new painted median with rumble stripes for additional safety. The spring-loaded channelizers can reset into their original position if they are ever hit by a vehicle, as opposed to standard channelizers which typically result in a broken post and need to be replaced after every incident. The combination of painted median with rumble stripes and channelizers has proven effective in reducing crossover collisions. The ability for the channelizer to reset after an incident has also increased the safety of our maintenance workers, who do not need to replace the channelizers as often as standard channelizers on this high-speed road.
