Abstract
This paper provides a wide range of information related to longitudinal joints of asphalt pavement, such as types of longitudinal joints, performance evaluations, factors of failure, and selection of the best practice in constructing longitudinal joints. Additionally, this synthesis provides an overview of construction methods which are typically used in constructing longitudinal joints, along with guides and approaches implemented by different road builders or authorities to attain a better longitudinal joint. It was found that difficulties during compaction of the asphalt pavement at the center line resulted in poor joint density. This has reduced the performance and durability of pavement that is associated with cracks and degradations due to moisture damage, such as raveling. Results from previous field studies and laboratory evaluations have been summarized to understand the factors of failure of the adjacent joint. The Michigan joint technique was found to be the best method in constructing longitudinal joints of HMA. The cutting wheel and the edge restraining device techniques are also recommended by the asphalt technologists however are dependent on the machine operator to obtain consistent results.
