Abstract:
This report contains a product evaluation of Ruscoe's 983 joint sealant. Ruscoe 983 is an asphalt base single compound joint sealant. It contains an aluminum fortified adhesive and is designed for use on highway expansion joints, bridge joints, and random cracks in both flexible pavement and portland cement concrete. Two different test sections of Ruscoe 983 were placed in Phoenix. One section was placed to evaluate the sealant capability in concrete joints. The other test section was asphalt cracks and asphalt to concrete joints. Both sections were placed using tubes of sealant and a caulking gun. The Ruscoe 983 joint sealant did not perform satisfactorily in any of the applications. The sealant didn't adhere well to either concrete or asphalt. Portions of the joint sealant were completely torn out. Based on field performance the Arizona Transportation Research Center recommends not using Ruscoe 983 joint sealant in Arizona pavement. /Abstract from report summary page/
