Understanding asphalt pavement distresses – five distresses

A pavement surface can become flushed with asphalt and lose its skid resistance. Bleeding can be caused by too much asphalt in the mix, excess tack or bond coat, or by poor construction of a sealcoat. Traffic can also over-compact an unstable mix and force asphalt to the surface. #5 Surface Treatment Distress

Bituminous pavement distress : cracks, causes and treatment

Cracking in the bituminous pavement is the most common distress. These cracks may be load associated (Bottom-Up cracks ) or Nonload associated (Top Down cracks ). In many cases, we can identify the cause of cracks from the pattern of the cracks. Ingress of water through wide cracks is harmful to the pavement structure. Type of road damage
