Book Synopsis Longitudinal Joint Specifications and Performance by : Rebecca S. McDaniel
Download or read book Longitudinal Joint Specifications and Performance written by Rebecca S. McDaniel and published by Purdue University Press. This book was released on 2012-12 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deterioration of longitudinal joints is widely recognized as one of the major factors contributing to failure of asphalt pavements. Finding ways to improve the durability of longitudinal joints will lead to improved service lives and lower life cycle costs. Research and field trials have been directed towards improving joint performance since at least the 1960s. Most of that work was addressed improving the density at and around the joint. This report summarizes an extensive review of the pertinent literature, a review of state specifications and inspection of several trial projects in Indiana related to longitudinal joint construction and performance. Recommendations are given for new and continuing efforts to encourage or require the construction of durable longitudinal joints.

Book Synopsis Fog Seal Performance on Asphalt Mixture Longitudinal Joints by : Sharlan Montgomery
Download or read book Fog Seal Performance on Asphalt Mixture Longitudinal Joints written by Sharlan Montgomery and published by . This book was released on 2018-05-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the nature of construction, it is common for longitudinal joints in asphalt pavements to have lower densities and higher permeabilities than the main portions of the pavement lanes. To address this concern, many states employ joint sealant techniques such as fog seals or void reducing asphalt membranes (VRAM). Qualitative evidence in Indiana appears to indicate that longitudinal joint lives have been improved by the use of joint sealers and adhesives, but the specific materials and application rates used to treat longitudinal joints has not been quantitatively investigated. This research aims to specifically investigate the fog seal materials and application rates specified for use on longitudinal joints in Indiana and to compare the performance of fog seal and VRAM treatments in order to provide guidelines for future joint sealant treatments. These objectives were accomplished by employing laboratory testing of both laboratory prepared specimens and field samples.The research performed on the laboratory specimens found the application of fog seals can improve the performance of the longitudinal joints with respect to permeability. While the permeability was affected by the presence of a fog seal treatment, the benefits were irrespective of the specific fog seal material. The results also indicate that the fog seal should be reapplied at 5-7 year intervals.The data from the field samples indicated that the VRAM samples had on average higher air void contents than did the SS-1h fog seal samples. Additionally, the VRAM samples had permeability coefficients that were statistically higher than the SS-1h fog seal samples. These differences may be attributable to the lack of VRAM migration up into the asphalt surface mixture. While the SS-1h fog seal treatment appears to have better performance than the VRAM, the effectiveness of the treatments over time is not known.

Available in PDF, EPUB and Kindle. Book excerpt: Construction of durable longitudinal joints is a critical element in the longevity of Hot Mix Asphalt (HMA) pavements. Achieving uniform density both longitudinally and transversely on the pavement will assist in meeting the goal of high-performance HMA pavements. A variety of techniques have been successfully used to construct good longitudinal joints. The objective of this document is to identify proper techniques for the various procedures, not to recommend a single technique.
Book Synopsis Use of J-band to Improve the Performance of the HMA Longitudinal Joint by : R.Christopher Williams
Download or read book Use of J-band to Improve the Performance of the HMA Longitudinal Joint written by R.Christopher Williams and published by . This book was released on 2020 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The density and air void content of asphalt mixtures affect the durability and performance of asphalt pavements. Pavement longitudinal joints typically have a lower density than the mat because they receive less compaction than the center section of the mat for various reasons. The higher air void percentages resulting from lower densities can lead to high permeability and allow water infiltration, which in turn can cause moisture-induced damage and decrease base and subbase support to the pavement, reducing pavement life. Void-reducing asphalt membrane (VRAM) has been used at the longitudinal joints of asphalt pavements to achieve higher densities and prevent moisture infiltration, thereby reducing deterioration at the longitudinal joints. VRAM is applied before the hot-mix asphalt (HMA) layer is placed and migrates into the HMA to fill 50% to 70% of the air voids. This research evaluated the extent to which J-Band, a VRAM product, increases density and improves performance. Field cores were collected from two sections, one with and one without VRAM. Asphalt mixture performance tests, including disk compact tension and semi-circular bend tests, and push-pull tests were carried out in the laboratory on the field-collected specimens. Volumetric measurements were also taken, and ground penetrating radar was used in the field. It was determined that the pavement sections with VRAM had a lower permeability, higher bond energy, and higher fracture energy than the pavement sections without VRAM.
Book Synopsis Construction of Longitudinal Joints in Flexible Pavements by : Steven McInnis
Download or read book Construction of Longitudinal Joints in Flexible Pavements written by Steven McInnis and published by . This book was released on 2008 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Improving the durability of asphalt pavements is an on-going goal to the Ontario Ministry of Transportation and the hot-mix industry. One way to achieve this goal is to construct proper longitudinal joints. While proper construction techniques are important in contributing to the quality of a longitudinal joint, increased awareness of the issues which should be considered during the planning and design of projects plays an equally important role in producing desirable joint quality. This report presents a holistic approach to improving the quality of the longitudinal joints which are expected to increase the durability of asphalt pavements."--Document.

Book Synopsis Best Practices for Concrete Pavement Transition Design and Construction by : Youn su Jung
Download or read book Best Practices for Concrete Pavement Transition Design and Construction written by Youn su Jung and published by . This book was released on 2007 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project conducted a survey of Texas Department of Transportation (TxDOT) and other state highway association (SHA) practices and identified the best practices toward incorporating them into guidelines for design and construction of transition areas that will enable TxDOT engineers and designers to avoid the inappropriate practices. The types of transitions that were addressed in this report covered a variety of concrete pavement combinations. Where possible, observed performances were documented based on survey results of many district practices and the findings of field visits. Based on these findings, improvements of various transition types were suggested to enhance the design standard for different transition types. Guidelines address the design of concrete pavements in transition areas with the joints and related details. The study of specific joint configurations associated with transitions was conducted with respect to stiffness of the joint, potential for permanent deformation, and slab restraint to translational movement at the joint. The 11 most frequently constructed types of concrete pavement transitions are introduced in this paper, and some of them have alternative designs as more options in the design guide.

Download or read book Asphalt Cement Concrete Longitudinal Joint Adhesive CRAFCO PN 34524 (Iowa DOT New Product C-98-7) written by Robert F. Steffes and published by . This book was released on 2000 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The joint between two lanes of asphalt pavement is often the first area of a roadway which shows signs of deterioration and requires maintenance. As the final lift of hot asphalt is being placed in a construction project, it is being forced up against the adjoining lane of cold asphalt, forming the longitudinal joint. The mating of the two lanes, to form a high quality seal, is often not fully successful and later results in premature stripping or raveling as water enters the unsealed joint. The application of a hot poured rubberized asphaltic joint sealant along the joint face in the final stage of construction should help to form a watertight joint seal. A new product, especially formulated for the longitudinal joint in asphalt pavements was proposed to improve joint sealing. The following describes the experimental application of the new product, Crafco, PN 34524.
