Longitudinal Joint Specifications and Performance

Abstract

Joint tranSportation reSearcH programThe Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction, operation, management and economic efficiency of the Indiana transportation infrastructure. https://engineering.purdue.edu/JTRP/index_html AbstractDeterioration 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 at 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 and possible future steps.17.

Specification Limits and Pay Adjustment for Longitudinal Joint Density of Asphalt Pavements: Case Study in New Jersey

“…State agencies vary widely in how they address joints in their specs. Table 1 summarizes the pavement mat and joint density specifications used by several state agencies (7)(8)(9)(10).…”

Fog Seal Performance on Asphalt Mixture Longitudinal Joints

“…To improve the performance of longitudinal joints, several construction methods have been implemented with varying degrees of success. Such methods include joint sealants, joint makers, joint heaters, wedge construction, edge restraint, and cutting wheels (Brown, 2006;Kandhal, Ramirez, & Ingram, 2002;McDaniel, Shah, & Olek, 2012;Prowell, 2009;Zinke, Mahone, Jackson, & Shaffer, 2008). Because application of joint sealants is easy, does not delay construction, and requires less labor and heavy equipment than other construction techniques, many types of joint sealants have been used on longitudinal joints with the primary intention of preventing the entrance of air and water, thus preserving joint integrity (Williams, 2011a).…”

Performance evaluation of a HMA pavement longitudinal joint containing a void reducing asphalt membrane (VRAM)

“…However, implementing these specifications requires some means of testing the quality of the joint. Density near the joint has been used as a measure of pavement performance (McDaniel et al, 2012). Other performance tests, such as joint crack resistance and bonding, have not been explored, especially in regions experiencing lowtemperature climates.…”
