• Abstract:
  When new asphalt is placed over concrete or ; asphalt pavement, cracks or joints in the old ; layer can appear in the new overlay; this is ; called reflective cracking (RC). In current Florida ; practice, an asphalt rubber membrane interlayer ; (ARMI) is placed between old and new pavements ; to reduce reflective cracking. However, ARMI has ; shown inconsistent performance and a recent ; accelerated pavement testing (APT) study found ; that ARMI can initiate instability rutting when ; subjected to slow moving truck loads and elevated ; summer temperatures. Therefore, the Florida ; Department of Transportation (FDOT) is seeking ; alternatives to prevent and mitigate RC.
