Longitudinal joints are discontinuities in the asphalt pavement structures, often missing good interlock between the aggregates, strong binder adhesion and sufficient treatment of the joint during construction with bonding agents. Furthermore, the density of the asphalt near the joint is generally lower than in the rest of the pavement. Therefore, joints are usually the weakest location in the structure and the effect of traffic loading and environment can cause premature failure at these locations. This study evaluates the durability of a novel type of joints constructed with induction heating using asphalt concrete with metallic additives. Previous laboratory tests suggest that these types of joints could outperform traditional construction methods. Four slabs with artificial longitudinal joints were prepared in the laboratory and loaded until failure with the downscaled model mobile load simulator MMLS3. In two of these slabs, the joints were built without any treatment and with a self-adhesive tape, accounting for standard joint construction procedures. In the other two slabs, metallic additives were locally added to the asphalt mixture close to the each joint and induction heating was used for improving the interlock and bond between the neighboring sides. For trafficking, the MMLS3 was placed on the slabs, such that footprint of the tires was just beside each joint. A comparative analysis of the fatigue performance of the different slabs shows that the novel designs could last two to six times longer than traditional joints.

“…The extent of heating decreased with depth and distance from the joint, as would be expected. The details of the temperature instrumentation and further analysis are given elsewhere (9,10). The finding from this study showed that the infrared heaters increased the temperature of the material near the joint to a range of 55°C to 65°C during compaction, with the highest temperatures seen during the initial compaction stage.…”

Longitudinal joint cracking is one of the most prevalent forms of distress in asphalt concrete pavements. The joint area does not achieve the same density as the mat because of an unconfined edge on the initial pass and a cold joint during the second pass. The lower density allows water to penetrate, and the material cracks, usually within a year of construction. There are many techniques for constructing longitudinal joints; one is to preheat the joint before paving the second lane. A field study conducted in New Hampshire used an infrared joint heater on the base, binder, and surface layers of a full-depth hot-mix asphalt pavement. Thermocouples were embedded in the pavement to determine the extent of heat penetration from the infrared heaters. Cores were taken along the joint and in the travel lanes for both control and infrared test sections. Density and strength measurements taken on the cores show some statistically significant improvements in the joint constructed by using the infrared heater. Permeability measurements along the control and test joints were performed and show average differences between the two sections. Cracking surveys on the binder and surface layers performed 1 year after construction showed that the section of pavement where the infrared heater was used has significantly less cracking than the control section.

“…In summary, the results were promising and showed that the joint heater did improve joint properties and performance. In a paper related to the study above (Daniel 2006), Daniel and Real discussed construction issues related to the use of joint heaters. Safety was one of the issues noted.…”

“…Another option to promote good joint performance is the use of infrared heaters to heat the edge of the cold mat before placing hot material beside it (2,9,10,(18)(19)(20). The goal is to reheat the pavement enough that it will adhere well to the adjacent lane, similar to a hot joint formed during echelon or tandem paving.…”

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.
