Download or read book Evaluation of Joint Sealants of Concrete Pavements written by Ashok H. Gurjar and published by . This book was released on 1997 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project 0-187 task 15 continued investigative efforts of project 1371. The project completed laboratory tests including relaxation tests, bond-strength tests, and fatigue tests for various sealant materials, and also established a field test site of a variety of joint sealants to monitor performance. The researchers constructed a material behavior model based on finite-deformation viscoelasticity as a function of temperature, deformation, and age effects. They studied the correlation between natural and artificial weathering and proposed a sealant performance model. Based on this model, this report provides a procedure for estimation of the service life of a sealant in concrete pavement joints. This report also proposes a specification and a test protocol for joint sealant materials, which incorporate performance prediction procedure.
