Book excerpt: Portland cement concrete (PCC) pavement joint sealing material technology has evolved in recent decades, and the effect of current joint sealant practice has not been well documented. Therefore, it is necessary to establish a standardized approach to joint sealant evaluation as well as to investigate the practice of joint sealant in PCC pavement design. The TRB National Cooperative Highway Research Program's NCHRP Synthesis 568: Portland Cement Concrete Pavement Joint Sealant Practices and Performance compiles and documents information regarding the current state of practice of joint sealing PCC by state departments of transportation.

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.

This book was released on 2015-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete pavements represent a large portion of the transportation infrastructure. While the vast majority of concrete pavements provide excellent long-term performance, a portion of these pavements have recently shown premature joint deterioration. Substantial interest has developed in understanding why premature joint deterioration is being observed in jointed portland cement concrete pavements (PCCP). While some have attributed this damage to insufficient air void systems, poor mixture design, or chemical reaction between the salt and the paste, it is the hypothesis of this work that a component of this damage can be attributed to fluid absorption at the joints and chemical reactions between the salt and chemistry of the matrix. This paper discusses the role of soy methyl ester - polystyrene blends (SME-PS) as a potential method to extend the service life of concrete pavements by limiting the ingress of salt solutions. The report discusses field application of the SME-PS blends for field investigation in Lafayette and Fishers. Low temperature-differential scanning calorimetry (LT-DSC) techniques identified noticeable differences between plain mortar samples and mortar treated with SME-PS. The report also discusses the development of a test to assess chloride solution ingress during temperature cycling. The aim of this work is to provide background on some aspects that can lead to joint deterioration and provide early documentation showing that sealers may help to reduce the impact of deicers on joint damage, thereby extending the life of the concrete pavement. It should be noted that these sites as well as others are still ongoing and should be monitored for long term performance. Application procedure for SME-PS should follow manufacturer's recommendation.

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.

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.

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.
