Abstract
Joint sealing materials, which are joint sealant and joint filler, are used to prevent the rainwater from intruding through the joints. However, the present standards for joint sealing materials might not reflect their required performance because the standard values are different, depending on their ingredients, and test methods for the materials are not specified. Therefore, the rational standards of joint sealing materials are required to reduce the cost for maintenance of airport concrete pavements. This paper describes the results of performance evaluation of joint sealing materials. As the result, it is clarified that temperature, environmental condition and cyclic compression affect on the performance of joint sealing materials.
