Book Synopsis Performance Evaluation of Portland Cement Concrete Pavement Joint Sealants by : Sylvester A. Kalevela

This book was released on 1994 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July 1986, the Arizona Transportation Research Center (ATRC) coordinated the installation of a joint sealant test site near Flagstaff, between mile posts 331.5 and 332.2, on the southbound lanes of Interstate 17. The original project was constructed in 1974, with 8 in. (20 cm) of portland cement concrete pavement (PCCP) over 6 in. (15 cm) of cement treated base (CTB). The test site consisted of 200 transverse joints sawed 2 in. (5 cm) deep, skewed 1:6, and spaced at a repeating sequence of 17, 15, 13, and 15 ft (5.2, 4.6, 4.0, and 4.6 m). The objective of the project was to evaluate the performance of five joint sealants: Dow Corning 888, Superseal 888, Allied Koch 9005, Crafco Roadsaver 231, and W.R. Meadows Sof-Seal. The highway sections abutting this test site were also rehabilitated and their pavement joints were sealed with Superseal 444 which, at that time, was a specified sealant in the Arizona Department of Transportation (ADOT) standards. Field evaluations of the joint sealants were performed at nine months, one year, 1.5 years, 3 years, and 8 years after construction. The evaluations were based on: (i) sealant flexibility, (ii) length of joint with missing sealant, (iii) adhesive and cohesive failure of sealant, (iv) joint width and sealant depth, (v) joint spalling, (vi) sealant recess, (vii) Falling Weight Deflectometer testing, and (viii) slab faulting. Generally, it appeared that after about eight years of service all five sealants had exhibited comparable performance level. Clearly, all test sealants performed better than Superseal 444 which was an ADOT specified joint sealant when the test site was installed in 1986.

Lynch and published by . This book was released on 1993 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the field evaluation phase of the joint effort research program conducted by Crafco, Incorporated, and the U.S. Army Engineer Waterways Experiment Station. The project was funded under the auspices of the FY 89 Construction Productivity Advancement Research (CPAR) Program. The objectives of the research effort were to (a) develop specification limits for a hot-applied, jet-fuel-resistant (JFR) sealant with improved performance characteristics as compared to current Federal Specification (FS) SS-S-1614A type materials, (b) develop specification limits for a hot-applied, non-jet- fuel-resistant (non-JFR) sealant with improved low temperature performance characteristics as compared to current FS SS-S-1401C type materials, (c) develop specification limits for a primer system that will minimize the bubbling tendencies associated with hot-applied sealants and improve adhesion characteristics to portland cement concrete (PCC), and (d) develop field data to determine performance characteristics of flush fill sealant application geometry versus 1/8 to 1/4 in. recess application techniques. The objectives were expanded to include field comparisons of the laboratory developed JFR and non- JFR sealants versus commercially available sealant materials and to verify that the developed primer system minimized bubbling tendencies of hot-applied sealants.

Book Synopsis Transverse Joint Sealing with Improved Sealants by : Gary Harris
Download or read book Transverse Joint Sealing with Improved Sealants written by Gary Harris and published by . This book was released on 1991 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about premature joint sealant failures occurring in portland cement concrete (PCC) pavements gave impetus to initiating this research project. Eight sealants, including three silicone sealants, were evaluated and tested in the lab as well as incorporated in approximately 700 joints in the field and evaluated over a six-year period. The preliminary data show that among the silicone sealants, Dow Corning 888 rated the highest. However, this was rated third overall behind the W.R. Meadows cold-applied Sof Seal and Crafco #231 hot pour sealants. The W.R. Meadows and Crafco sealants cost approximately 30% and 50% less to furnish and place than the Dow Corning product. All joint sealants will continue to be evaluated.

Book Synopsis Evaluation of Joint Sealant Materials, US-36, Doniphan County, Kansas by : Rodney A. Montney
Download or read book Evaluation of Joint Sealant Materials, US-36, Doniphan County, Kansas written by Rodney A. Montney and published by . This book was released on 2009 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Kansas Department of Transportation began using silicone joint sealant on Portland Cement Concrete Pavement (PCCP) almost exclusively in 1983. During the next 6 years there was widespread failure of these products. A project was constructed in 1990 to evaluate several different types of joint sealants available. While most of the silicone products in this study appeared to outperform the other types, KDOT could not ignore the failure rate of the previously installed silicone sealants. During the course of this investigation, KDOT issued a policy on sealing new PCCP joints. The policy requires preformed neoprene seals in all transverse joints, and allows longitudinal joints to be filled full depth with either hot or cold pour sealants.

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.
