Preventions of Reflection Cracking in Asphalt Overlays ...

2015-6-1  Prevention of Reflection Cracking in Asphalt Overlays With Structofors, Petromat, and Cerex INTRODUCTION One of the most persistent problems with asphaltic concrete resurfacing is that cracks almost always appear in an overlay wherever cracks existed in the underlying pavement. This is generally ref erred to as reflection cracking.

Prediction of Reflection Cracking in Hot-Mix Asphalt

2010-1-1  Abstract. Reflection cracking is one of the main distresses in hot-mix asphalt (HMA) overlays. It has been a serious concern since the early 20th century. Until now, only limited research has been performed to predict reflection cracking. Mechanistic-based models were calibrated to field data to produce a design process for predicting reflection ...

Prediction of Reflection Cracking in Hot Mix Asphalt

In this dissertation, mechanistic-based models are calibrated to field data of over 400 overlay test sections to produce a design process for predicting reflection cracks. Three cracking mechanisms: bending, shearing traffic stresses, and thermal stress are taken into account to evaluate the rate of growth of the three increasing levels of distress severity: low, medium, and high.

There is then shifting or movement of the old pavement. These cracks or joints can reflect from that pavement to the surface. Crack sealant can sometimes fix low severity cracks.

Effects of an Asphalt Rubber Membrane Interlayer on ...

When hot mix asphalt (HMA) overlays are placed on distressed flexible or rigid pavement, it is only a matter of time before cracks in existing pavement reflect to the new overlay surface. Asphalt rubber membrane interlayer (ARMI) is one type of interlayer system that has been suggested to mitigate reflective cracking in HMA overlay.
