Evaluation of Longitudinal Joint Density
Record Type: DOT
The longitudinal joint between asphalt mats is a major area of pavement distress. During the placement of asphalt pavement it is difficult to compact the unconfined edge, which typically results in lower densities than in the remainder of the asphalt mat. To address the problem, a Colorado Department of Transportation (CDOT) task force developed an end result specification based on longitudinal joint density. Seven projects constructed under the new longitudinal joint density specification in 2004 will be compared to seven projects that were constructed, monitored, and documented in 2000.
