Longitudinal Joint in Asphalt Pavement

Longitudinal Joint in Asphalt Pavement A longitudinal joint occurs in an asphalt pavement when a fresh batch of hot-mix asphalt (HMA) is laid adjacent to an existing lane. It is required to pave the width of a road in multiple lanes because paving the full width of the pavement in a single pass is usually impossible. It is the interface between the two HMA mats. Most often, differences in the ...

ELIMINATE COLD JOINTS PERMANENTLY

joints are an inherent weak area of the pavement surface. A cold joint is created when asphalt paved in the first paver pass has cooled to a temperature (probably below approximately 50C). The adjoining paver pass will install asphalt at its normal hot temperature but the temperature difference between the two mats / paver runs is such that the two surfaces will not bind cohesively together ...

LONGITUDINAL JOINT CONSTRUCTION TECHNIQUES FOR ASPHALT

FOR ASPHALT PAVEMENTS BACKGROUND Cracking and raveling are the two main distress conditions which are commonly encountered at the longitudinal joints of multilane hot mix asphalt (HMA) pavements. These distresses are caused by relatively low density and surface irregularity at the joints. A density gradient also exists across a typical longitudinal joint. Such a density gradient is caused by ...

A look at longitudinal joint ... - Asphalt magazine

In an asphalt pavement, longitudinal joints occur where one paving lane (also called a “mat”) is placed adjacent to an earlier placed paving lane. The localized area of the longitudinal joint is more difficult to compact and, as a result, has higher in-place air voids compared to the interior of the mat. While in-place void levels at the interior of the mat are typically 6-8 percent (92-94 ...
