Evaluation of stripseal for use in expansion joints

The expansion joints in the bridge deck are provided to accommodate the structural movements due to a number of internal and external factors, such as variations in temperature, imposition of life loads, earthquake and shrinkage. These expansion joints malfunction due to various reasons and cause discomfort to users. The strip seal expansion joints are provided with a special shaped seal of elastomeric material, such as chloroprene, to span the joint opening. This important component of the expansion joint assembly deteriorates with age or due to improper vulcanization of the rubber during its conversion to chloroprene or due to the use of poor quality rubber to make it cost-effective. There are various tests that are required to be qualified by the chloroprenestrip seal. This paper highlights the tests to be performed on the raw material of strip seal to ascertain the functional performance. Also, a comparison of physical properties of chloroprene and ordinary rubber is presented for the benefit of bridge engineers.
