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 /> 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 perform 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 /> 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 /> 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 />
