2014 Slurry Seal Project 

City Project No. 2014-04

Slurry seal treatment is a cost effective maintenance procedure that extends the life of City streets. Treated streets receive pavement section repairs as needed, typically four to six inches deep, followed by slurry seal treatment consisting of a 1/4-inch to 3/8-inch layer of asphalt material and fine aggregate. The work also includes installation of striping and pavement markings. The 2014 Slurry Seal Project will rehabilitate approximately 9 centerline miles of residential, industrial, collector and arterial streets and selected the City parking lots.  The project will also reconfigure the intersection of Murrieta and Stanley in response to shifting traffic patterns.  On July 14, 2014 the Livermore City Council approved a contract with American Asphalt for construction of this project.  Construction started in August 2014 and is now complete.

2014 Resurfacing Project

City Project No. 2014-01

Street resurfacing (asphalt overlay) consists of a 1½ to 2 inch thick layer of asphalt concrete applied to existing streets that are in need of rehabilitation.  Depending on the condition of the street, various types of treatments may be specified.  Some treatment options include base repairs, surface milling, application of an asphalt concrete leveling course, stabilizing fabric and a final layer of new asphalt.  New striping is then applied to the resurfaced streets.

The 2014 Street Resurfacing Project will resurface approximately 2.8 centerline miles of Livermore Streets.  The project includes the construction of ADA accessible curb ramps and repair of sidewalk, curb, gutter and valley gutter within the limits of the project.  The project also includes reconstruction of Preston Avenue west of Southfront Road.  On September 8, 2014 the Livermore City Council awarded the contract for this project to Top Grade Construction.  Top Grade Construction has their headquarters here in Livermore.  Construction will begin in mid-September and should be complete in mid-December.
