rehabilitation method for composite pavements and to evaluate the influence of different factors on reflective crack development. Four rehabilitation methods, including mill and fill, overlay, heater scarification (SCR), and rubblization, were analyzed using three performance indicators: reflective cracking, international. MINIMIZING REFLECTION CRACKING. OF PAVEMENT OVERLAYS. RESEARCH SPONSORED BY THE AMERICAN. ASSOCIATION OF STATE HIGHWAY AND. TRANSPORTATION OFFICIALS IN COOPERATION. WITH THE FEDERAL HIGHWAY ADMINISTRATION. TRANSPORTATION RESEARCH BOARD. IIlATIONAL. A Reflective crack is a type of failure in asphalt pavement, one of the most popular road surface types. Asphalt pavement is impacted by traffic and thermal loading. Due to loading, cracks can appear on pavement surface that can reduce the Pavement Condition Index(PCI) dramatically. The pavement can be maintained by. CRACKING SOLUTIONS FOR CRACKING PROBLEMS. Reduction and avoidance of reflective cracking and deformation of pavement surfaces is achievable with the use of the GlasGrid® range of geosynthetic and geogrid products from Asphalt Reinforcement Services. Formation of cracks in asphalt pavement overlays is. The primary objective of this field phase of the research project was to evaluate geosynthetic products placed under or within hot mix asphalt overlays to reduce the severity or delay the appearance of reflection cracks and to calibrate and validate FPS-19 Design Check. Multiple end-to-end test pavements incorporating. reflection cracks, as they coincided with the loca tions of construction joints in. it displayed pronounced scaling, erosion, crack ing, and spalling. Further, freezingandthawing. Fig. 1: Ruskin Dam and 105 MW generating station. The spillway. (inset) has undergone. the overlay and substrate were deemed sound (Fig. 5(a)).
