Todd Blomstrom, PE <br />May 6, 2020 <br />Page 5 <br />Summary and Recommendations <br />Jerrold Avenue and Edgewater Avenue <br />The cores obtained along Jerrold Avenue and Edgewater Avenue had bituminous depths ranging <br />from 4 inches to 6.75 inches, with at least 3 inches of underlying aggregate base. All the cores <br />were in fair to poor condition, exhibiting distresses such as delamination or deterioration. <br /> <br />Due to the poor condition of the cores, it is recommended to perform a full depth reclamation <br />(FDR). This rehabilitation method would remove all the existing distresses, and re-blend the <br />bituminous and a portion of the aggregate as a base to re-pave over, essentially creating a new <br />roadway section. Another alternative is to perf orm a full depth bituminous removal and <br />replacement on these roadways. This type of pavement preservation would also completely <br />remove the crack pattern within the existing pavement. <br /> <br />Lake Valentine Road <br />Four cores obtained along Lake Valentine Road had bituminous thicknesses from 5 inches to 6 <br />inches, with a top lift of 2 inches. All the cores were observed to be in good condition. The <br />surface of the street was observed to be in good condition with low severity cracking. There was <br />at least 7 inches of underlying aggregate base, which was found to be recycled material. The <br />recycled material may be the root cause of the formation of the cracking pattern as well as the <br />tenting of the transverse cracks. <br /> <br />It is recommended to perform an FDR as a long-term fix on Lake Valentine Road. By grinding the <br />existing bituminous together with the underlying recycled material, this rehabilitation method will <br />help to mitigate the crack pattern from surfacing through the new bituminous pavement. <br /> <br /> <br /> <br /> <br /> <br />
