Description
Displacement of the HMA mixture in a longitudinal direction while compacting. Shoving under traffic loading is covered in a seperate article.
Problem
Mats that shove under compaction loading are generally unstable and are likely to continue to deform under traffic loading leading to roughness problems. If a mat is not adequately compacted because it is shoving, the resulting low density can cause the mat to be susceptible to decreased stiffness, reduced fatigue life, accelerated aging/decreased durability, rutting, raveling, and moisture damage (Hughes, 19841; Hughes, 19892).
Possible Causes
Solutions
Eliminate the causes for tender mixes or develop a compaction sequence and pattern to accommodate the tender mix. Compaction sequence and patterns will depend upon the type of mix tenderness.
