Description
Low temperature cracking occurs when cold weather temperatures cause the upper part of a pavement section to contract, while the pavement’s bottom section is held in place by its granular base and prevented from contracting. To relieve stress, cracks are formed at semi-regular intervals, thus degrading the pavement and reducing riding comfort. Low temperature cracking is the main cause of pavement roughness and reduced service life in northern climates.
