Book Description
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 Description
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.

Pages : 132
Book Description
This report presents the results of laboratory tests, field studies, and literature searches which pertain to the behavior of concrete pavement joints, slabs, and joint sealing materials. A review of common pavement joint and pavement slab failures is presented. The properties of several commonly used joint sealant materials are also discussed. Results of a field test of the silicone and polysulfide are presented. Observations of existing joints at various places in Texas and Oklahoma are also presented. Results of field tests reported in the literature on silicones, polysulfides, polyurethanes, rubberized asphalts, and preformed neoprene rubber seals are summarized.

Pages : 204
Book Description
In conducting this investigation, detailed surveys on 85 pavement projects in 7 States were made. These pavements were generally under 15 years old, and reinforced and continuously reinforced pavements. The results of this investigation are contained in the report as prepared by PCA. Some of the aspects of Portland Cement Concrete pavements covered include: 1) Categories and characteristics of PCC pavements; 2) Pavement problems, their causes and required maintenance; 3) A pavement performance and condition survey; 4) A charted summary, design, and construction practices of the states (available separately on request); 5) Construction and maintenance costs, and 6) Design and construction recommendations.

Modeling of Portland Cement Concrete Pavement Longitudinal Joint Distress

ISBN:
Category : Pavements, Concrete
Languages : en
Pages : 174
Book Description
Longitudinal joints of concrete pavements constitute essential elements in the overall functionality and performance of the pavement system. The noticeable deterioration of these joints on some of Kansas highways lead to performing a preliminary study in order to determine the severity of the problem and analyze the design and construction issues that might have contributed to the observed damage. Data was collected from 31 sections of interstate highway in the Kansas City, Kansas metropolitan area. Parameters such as the age of the pavement and sealant, accumulated volumes of total and heavy traffic, type of joint, slab length, slab thickness, concrete strength, steel reinforcement, etc. were analyzed in relation to the observed spalling of the longitudinal joints. The variation of these parameters, with the spalling measures presented in this report, was studied.
