King City Capital Preventative Maintenance

proposed

Caltrans proposes to preserve the pavement on an 8-mile section of U.S. 101 near King City, between Jolon Road and Lagomarsino Avenue, in Monterey County. The project would implement preventative maintenance strategies to maintain the roadbed and improve ride quality as part of the 2020 State Highway Operation and Protection Program (SHOPP). The scope of work includes cold-planing the existing open grade friction course pavement and placing a 0.15-foot rubberized hot mix asphalt overlay, replacing or rehabilitating three drainage culverts, adding three new street lights at the Jolon Road interchange, and replacing a weigh-in-motion station (in Greenfield) and traffic census stations. Other improvements include upgrading guardrail and guardrail end treatments, vegetation control, and doing minor concrete, shoulder backing and pavement dig outs. The existing pavement was constructed in 1956. Since then, pavement rehabilitation improvement projects have been limited to repair with thin, new wear courses, most recently in 2011. The pavement wear course, if not replaced, will degrade to a point where water intrusion would result in failure of the underlying layers, leading to more costly reconstruction.
