• Abstract:
  No current pavement rehabilitation techniques have been shown to prevent reflective cracking. However, several techniques have demonstrated the ability to reduce reflective cracking. Application of geosynthetics is only one of a number of techniques. Available methods usually fall under one or more of three categories, shown in Figure 1. Other methods to address reflection cracking might include: a seal coat applied to the existing pavement, thick large stone open-graded asphalt stabilized layer (Arkansas mix), saw and seal the HMA overlay, and cracking and seating or rubblizing of concrete pavements. These guidelines will deal strictly with geosynthetics for reducing reflection cracking.
