Alligator Cracks Alligatored asphalt is characterized by interconnected cracks forming small pieces that range in size from about 1” to 6” and appear much like alligator skin. This damage is caused by failure of the surfacing due to traffic loading and often due to inadequate base or deficient subgrade support. If the subsurface is not [...]

Asphalt Damage, Part 6, Block Cracks
Block cracking is identified by interconnected cracks joining to form large blocks. The cracks usually intersect at nearly right angles. Blocks range from one foot to nearly ten feet or more across. The closer-spaced blocks indicate more advanced aging caused by shrinking and hardening of the asphalt over time. Repair with sealcoating during early stages to reduce weathering [...]
Asphalt Damage, Part 5 and 6
Because these Paser descriptions were so short, I’m including two asphalt damage suggestions in today’s blog. Reflection cracks Cracks in overlays reflect the crack pattern in the pavement underneath. They are difficult to prevent but not hard to correct. A quick overlays with FloMix will solve the problem with no digout or removal. Slippage [...]
Transverse Cracks in Asphalt
A crack forming at an approximate right angle to the center line is a transverse crack. They are often regularly spaced. They are caused by movement due to temperature changes and aging, hardening asphalt. Transverse cracks will initially be widely spaced (over 50’). Additional cracking will occur as they age until they are closely spaced [...]
Asphalt Damage, Part 4, Distortion
Shoving or rippling is caused by surfacing material displacing crossways to the direction of traffic. It can develop into washboarding when the asphalt mixture is unstable because of poor-quality aggregate or improper mix design. Very large repairs can be handled by milling smooth and overlaying with stable asphalt mix. This may not last for a [...]
Asphalt Rutting
Rutting is displacement of material, creating channels in wheelpaths. It is caused by traffic compaction or displacement of unstable material. Severe rutting (over 2”) may be caused by base or subgrade consolidation. Repair minor rutting with a thin layer of FloMix. Severe rutting may require some preplacement of BlakRok before completing the repair with FloMix.
Asphalt Damage, Part 1, Raveling
This week I begin detailing the types of asphalt damage as described in the Paser Manual.

It describes 12 types of defects and provides a simple system to visually rate pavement conditions. The rating procedure is used as condition [...]
