Page 3 of 6 <br /> <br />Preventative Maintenance <br />The project's second component consisted of preparatory work for slurry sealing, which was <br />performed under a separate contract. The preparatory work included isolated full-depth <br />pavement repair and crack sealing. A total of 45,000 square feet of distressed pavement area <br />was removed, 4 to 6 inches from the pavement’s surface, down to the roadway aggregate <br />base material, and replaced with new asphalt concrete with the same thickness as removed. <br />This was done when the pavement failed in isolated areas and before the street surface was <br />slurry sealed. This is the same repair method performed on the reconstructed streets, as <br />described above. A total of 5,500 pounds of crack sealant was applied to the roadway <br />pavement as part of preparatory work. Crack sealing involved cleaning the pavement cracks <br />to prepare them for a sealant, which was then smoothed to flush the material with the existing <br />asphalt concrete surface. <br /> <br />After the preparatory work, 0.60 million square feet of roadway surface slurry seal was placed <br />on the streets listed in Table 2 below. <br /> <br />Page 110 of 264
