FREQUENTLY ASKED QUESTIONS

What are Alligator Cracks?

Alligator Cracks are interconnected cracks forming a series of small blocks of asphalt resembling alligator skin or chicken-wire, and caused by excessive deflection of the surface over unstable sub-grade or lower courses of the pavement.

Is R/R Necessary?

A general rule in regards to whether or not you need to R/R (Remove and Replace) asphalt that has for example developed alligator cracking, is that if the alligator cracking has created sections of asphalt smaller than the palm of your hand, then it may be best to completely remove and replace that effected area of asphalt. Another option may be to grind the damaged pavement down and add a Fabric Interlayer, such as Petromat, with 1.5" of hot asphalt on top. These appropriate repairs are better able to fight against reflective cracking and last longer than solely adding an inch of hot asphalt. Count on United Paving to assess the deterioration of your asphalt and explain which treatments should perform the best.
