Maryland Method Longitudinal Joint Compaction

The process of creating the optimal asphalt joint aside a previously created joint follows a few simple rules. First overlap the adjoining lap 1.5″. Second, lock and consolidate the pavement a foot off the new joint. This creates an area of resistance which confines the mix during the second step and forces mix towards the existing joint. The third step uses the full force provided by the compactor to compress the asphalt pavement into a confined space filling voids which could lead to premature joint failure.
