Available in PDF, EPUB and Kindle. Book excerpt: This synthesis document will be of interest to materials, maintenance, and bridge engineers, and others responsible for protecting and maintaining portland cement concrete (PCC) roadway surfaces. It will be of special interest to materials research and testing officials, as well as to manufacturers who are concerned with developing and evaluating sealers for PCC highway facilities. The information in this Synthesis is limited to surface-applied liquid sealers that are primarily intended to retard the transmission of water and ions below the roadway surface. This report of the Transportation Research Board provides detailed information on generic concrete sealing materials that may be considered a primer on the topic, describing the various classes of sealers, their chemical characteristics, application to specific needs, and practice and performance characteristics. In addition, information is provided on evaluation and testing, application and costs, and the safety and environmental issues of concern with their use. Also included is a glossary of terms, extensive references, and an appendix that includes materials on a procedure for the estimation of service life and a model sealer specification.

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.

This book was released on 1959 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: The performance of sealing materials for sawed joints is being studied by a laboratory test in which the joints are opened and closed at speeds of the order of 1/32 inch per hour. The sealers are applied to sawed joints which are initially 1/8 or 3/16 inch wide and which are usually opened an additional 1/8 inch at 0 F during the tests. Paper 2: 16 laboratories were asked to participate in the evaluation of bond-ductility, flow, and penetration tests for joint sealing compounds. three hot-poured type rubber -asphalt sealants were used in this testing program. the material samples, together with special mortar test blocks for the bond-ductility test, were sent to all participants from one centralized source, the federal specification SS-R-406C procedure was used, emphasizing certain details in order to have the test better controlled.

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.
