Longitudinal Joint in Asphalt Pavement

of the fresh HMA with the older asphalt lane and this subsequently causes the longitudinal joint to possess a significantly lower density than the rest of the pavement. Over time, a longitudinal crack usually occurs between the asphalt mats, permitting the intrusion of water, increasing roughness, and potentially limiting the life of the pavement.

Crack Routing. For crack sealing, route cracks to be sealed by forming a reservoir with a width between 0.5 in. to 1.5 in and a depth of 3/4 in. Perform routing in such a way that the pavement does not spall. Do not perform routing on longitudinal joint cracks unless otherwise directed. 510.03.06 Weather Restrictions.

Pavement Distress Summary - Asphalt Institute

Dry Surface/Cracking: Old and dried out mix; Mix was placed too dry. Fog seal, slurry seal or overlay. Edge Cracks: Lack of lateral support; Settlement of underlying material; Shrinkage of drying out soil. Improve drainage. Remove trees, shrubs etc., close to edge. Fill cracks with asphalt emulsion slurry or emulsified asphalt. Edge Joint Cracks

Longitudinal and Transverse (L&T) Cracking

Longitudinal and Transverse (L&T) Cracking. Longitudinal cracks are parallel to the pavement's center line or lay down direction. They may be caused by (1) a poorly constructed paving lane joint, (2) shrinkage of the AC surface due to low temperatures or hardening of the asphalt, or (3) a reflective crack caused by cracks beneath the surface course, including cracks in PCC …

NS-647 - Mitigation of tenting of transverse cracks and ...

transverse cracking compared to the AC mix. This finding is validated using the field survey data. It is found that OGFC prevents the low -temperature transverse crack growth in asphalt pavement. Therefore, OGFC can be considered a good potential material to resist low-temperature transverse cracking, especially in cold regions.

Joint Reflection Cracking (7)

Joint Reflection Cracking (7) Description. This distress occurs only on pavements having an asphalt or tar surface over a PCC slab. This category does not include reflection cracking from any other type of base (that is, cement stabilized, lime stabilized). Such cracks are listed as longitudinal and transverse cracks.

Longitudinal Joint Construction – Pavement Interactive

A longitudinal joint is the interface between two adjacent and parallel HMA mats. Improperly constructed longitudinal joints can cause premature deterioration of multilane HMA pavements in the form of cracking and raveling (Figures 1 and 2). These distresses, caused by relatively low density (high air voids) and surface irregularity at the joints, can largely be avoided through …
