Most highway agencies have established policies that specify the type of Crack Sealing Machine maintenance to be performed on cracked pavements and when to perform it. The policies are often based on an assessment of the overall pavement condition (extent of cracking) or specific crack characteristics(type and width) before Crack Sealing Machine prepare working.
On occasion, cracks may have other types of deficiencies. In particular, crack edges may exhibit vertical distresses, such as cupping, lipping, or faulting or may undergo significant vertical deflections or movements under traffic loading. Such deficiencies can add significantly to overall pavement roughness and can deteriorate rapidly.
Normally, repair alternatives such as patching or milling are appropriate for correcting these deficiencies. However, if the amount of vertical deflection and the severity of the distress are not too high, a temporary fix with crack treatment by using Crack Sealing Machine may be adequate.
