Title: Construction of Durable Longitudinal Joints
Accession Number: 01033779
Record Type: Component
Availability: Find a library where document is available Abstract: The durability of longitudinal joints in asphalt concrete pavements is a major problem at many locations across New Jersey. After a short period of time under traffic, these joints tend to ravel. In some cases the raveling is severe enough to completely erode the mix at the joint leaving a gap between the lanes. There are a number of factors during construction that directly affect the durability of a longitudinal joint. The first is the compaction of the unsupported edge of the first lane of mix placed. The second is the amount of overlap of mix on the second lane over the top of the first lane. The third factor is related to the raking of the mix at the joint. The final primary factor is the compaction of the mix at the joint when the second lane is placed adjacent to the first lane. The construction of a longitudinal wedge joint is also discussed. Construction of a durable longitudinal joint is a question of good workmanship by the contractor using proper construction techniques.
