There are usually three types of bitumen damage: surface, coating and structural damage. If the surface is damaged, problems with transverse or longitudinal cracks can occur. Raveling is the loss of aggregate from the surface due to wheel abrasion.

A broken joint is usually a slide between two layers of soil, causing a crack in the top layer. In some cases, the combination of bonding and crack damage causes the top layer to peel off.

The most serious defects are structural cracks, which can include cracking and fatigue. Tiring cracks are the result of surfaces bent up and down due to heavy load trajectories. The cracks are very close together and look like crocodile skin. This damage occurs when the main part of the road can no longer support the loads placed on the sidewalk.

One heavy truck can bend and damage the roads of more than a thousand cars passing through the same location. The knee is a hollow in the highway in a bicycle lane and is usually continuous over the highway. It can appear only on asphalt layers or across asphalt, base and ground infrastructure.

Types of treatment:- Different types of measures to choose from depending on the defect and the degree of damage to the road surface. Possible solutions may include surface densification coatings, crack filling, suspension seals, touch and selective digging, or full coatings.
