INFLUENCE OF RELATIVE RIGIDITY ON THE PROBLEM OF REFLECTION CRACKING.
Reflection cracking of bituminous overlays on rigid pavements has been studied on a basis of theoretical and experimental investigations. As a result a number of solutions were tried, but in most cases performance was reported as poor to fair. A recent investigation oriented toward the use of a plastic mesh to reinforce asphalt pavements resulted in the development of a new analytical approach that helps explain the actual causes of reflection cracking in bituminous overlays. The new approach adopts the principle of 'relative rigidity' to analyze the pavement structure at the time of construction. Results of the analysis have indicated that the critical interface is the one at the top surface of the softer hot asphalt layer.
