Abstract:

Reflective cracking in hot-mix asphalt (HMA) overlays on existing jointed concrete airfield and highway pavements is a significant issue. The complexity of reflective cracking arises from the combined effects of temperature changes and vehicular loads, which increase stresses in the overlays. Current FAA structural design guidelines for overlays do not address reflective cracking, highlighting the need for fundamental fracture-based design models for airfield HMA overlays to be included in the FAA’s FAARFIELD pavement design software. The proposed research involves developing advanced 3-D fracture simulations to understand the reflective cracking mechanism in airfield pavements to develop a mechanistic-empirical model for asphalt concrete overlay design.
