Based on these surveys, various City streets <br />were recommended for rehabilitation or reconstruction based on the following: 1) pavement <br />condition; 2) amount of project funds available; 3) proximity to future land development <br />projects; and 4) other engineering considerations. <br />Road rehabilitation will be done through two methods. 1) Heavily weathered pavement with a <br />stable base will have the top two inches of asphalt concrete (AC) removed and replaced. 2) <br />Pavement with depressions from wheel loads will have four inches of AC removed and <br />replaced. The AC will be installed in two lifts of two inches each with a layer of pavement <br />reinforcement mesh in between. The mesh helps dissipate vertical crack stresses and <br />prolongs the life of the pavement by mitigating crack propagation. <br />Reconstruction will be done by installing a new pavement section consisting of AC on top of a <br />cement stabilized base. This process involves demolishing the existing AC pavement, mixing <br />cement into the road base to provide a stable foundation, and installing a surface course of <br />new AC. This method of rehabilitation costs significantly less than traditional road <br />Page 1 City of San Leandro Printed on 4/30/2013
