Stop being premature

摘要

Once in a while, especially in cold-weather states, joints in concrete pavements have shown signs of deterioration relatively soon after pavement construction (five to 10 years). The phenomenon, known as premature joint distress, usually presents as shadowing, microcracking and flaking. These tell-tale signs can progress to joint spalling and significant loss of material along the joint. Unless the damage is repaired and the underlying causes are addressed, premature joint distress can reduce a pavement's service life.
