BACKGROUND:
The City Council awarded Contract 20-005 to K-Five Construction Corporation on June 2, 2020, with a completion date of October 31, 2020. The purpose of this contract is to resurface and reconstruct various city streets as part of the annual street maintenance program.
DISCUSSION:
This change order is requested to add a pay item of Longitudinal Joint Sealant. Longitudinal joint deterioration of Hot Mix Asphalt pavement has been overserved as a problem through Illinois. For any resurfaced/reconstructed asphalt roadway, longitudinal joint cracks usually first develop before any other cracks appear. Water and air will infiltrate through the longitudinal joint crack, which affects the durability of the pavement and leads to additional cracking and raveling. In the past, different joint seals have been investigated to evaluate the effectiveness of the different type of product. During a recent study released by Illinois Department of Transportation (IDOT), two products, the Emulsicoat Jband and the Quick Pave Products QuickSeam, were evaluated to determine the potential in minimizing joint deterioration. Based on the long-term field performance study, both products have shown to significantly decrease joint permeability, and therefore could extend the life of the roadway. We would like to use it on Gartner Road and compare it with other streets without using the sealant for effectiveness.
The amount of this change order exceeds the original contract amount by $9,800.00 and no change to the original contract expiration date.
