Although joints will usually be the first thing to deteriorate in asphalt, improper paver operation can cause excessively weak joints that separate prematurely.

Transverse Cracking Study of Asphalt Pavement

Initially, a transverse crack does not adversely affect the riding quality of a pavement. Water action in the transverse crack causes stripping of the asphalt cement and with time results in a void. (figure 2) This void then allows settlement, sloughing and results in a badly deteriorated type 4 joint.
