Title

Interstate 40 Minor Pavement Rehabilitation Project

Description

The California Department of Transportation (Caltrans) proposes to install 0.15-ft thick Rubberized Hot Mix Asphalt (RHMA-G) overlay on the I-40 mainline and shoulders; construct 0.4-ft thick localized digouts (10% of total Asphalt Concrete[AC]); replace AC dikes; upgrade existing metal beam guardrail to Midwest Guardrail System (MGS); replace rock slope protection under two bridges at Gas Line Wash due to inadequate rock type and size; replace traffic sign panels with type XI retro-reflective sheeting to meet federal requirements, and replace four culverts in poor or fair condition under Drainage Restoration program in order to protect the embankment and roadway from potential failure. The pavement grinding would include the removal of thermoplastic traffic stripes. Lane closure would be required to minimize traffic impact during construction and to ensure the safety of the traveling public and construction workers. Construction is expected in the night time and 8 hours a night. The new MGS at the bridge locations will be connected to a new concrete barrier transition at the beginning and the end of each bridge railing. The concrete barrier transition will be attached through drilling and bonding into the existing bridge railing. Asbestos testing may be required for the existing bridge railing. No other bridge work is planned. Below is the list of all bridges that require concrete barrier transition: Gas Line Wash-Bridge No. 54-0715 R/L, Twin Hills Wash-Bridge No. 54-0716 R/L, Crest Wash-Bridge No. 54-0717 R/L, W Newberry Road Undercrossing-Bridge No. 54-0708 R/L, Newberry Road Overcrossing-Bridge No. 54-0709, Fort Cady Overcrossing-Bridge No 54-0710. All work is expected to be performed within the existing Caltrans right of way.
