Anti-Reflective Cracking Design of (Reinforced) Asphaltic Overlays
Reflective cracking in asphaltic overlays can be caused by traffic, temperature variations (daily or seasonal) and/or uneven soil movements; the latter can be of a downwards (settlements), upwards (frost heave) or of a horizontal nature (shrinkage of clay). During the design of new pavement structures the so-called reflective cracking potential has to be taken into account by selecting a proper crack or joint pattern in the base layers. Smaller distances between cracks and joints imply, that the movements at the edges of the slabs decrease (vertical as well as horizontal) however, the flexural stiffness f the total structure will become less, with a larger deflection due to passing wheel load as a consequence. To delay or arrest reflective cracking in asphaltic overlays, which are to e constructed on existing cracked pavement structures, either optimized/modified asphaltic mixtures and/or stress-relieving/reinforcing systems can be utilized.
