Book Description
The objective of this research project was to conduct a literature review on longitudinal joint construction for hot- mix asphalt pavements. The review covered the issues related to the principles of hotmix asphalt paving and compaction for longitudinal joint construction, longitudinal joint problems, and some longitudinal joint construction techniques and specifications from different studies. Specific recommendations have also been made for application in the State of Kansas.

Book Description
"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 Description
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.

Book Description
The construction of longitudinal joints in an asphalt pavement is typically the most difficult to achieve high density due to viscosity of pavements at high temperatures. Thus, deterioration of longitudinal joints is one of the major distresses facing agencies. The goal of this Tech Transfer would be to compile research and specifications from the NRRA states and others into a synthesis for publication.
