Mitigation of Reflection Cracking in Asphalt Concrete Overlay on Rigid Pavements

Concrete Overlays as a Rehabilitation Option for Distressed Asphalt Pavements

Rut Resistant Asphalt Pavements

The three major distress conditions affecting the performance of asphalt pavements are permanent deformation or rutting, fatigue or load associated cracking, and low temperature or thermal cracking. In an earlier technical topics article (Fall, 1998), we examined the causes of fatigue cracking and the importance of good compaction during construction to help minimize this type of distress. In t...

Non-destructive evaluation of in-place rehabilitated concrete pavements

Several in-place rehabilitation techniques have been used before placing an Asphalt Concrete (AC) overlay on Portland Cement Concrete (PCC) pavements in attempts to minimize reflection cracking. Among these techniques, "rubblization" of PCC has been recognized to be the most utilized procedure for the mitigation of reflection cracking in US. This paper presents the practices on the use of rubbl...

This report provides a summary of the results of the various studies completed in the Partnered Pavement Research Program (PPRC) during the period 2000–2004. In addition, preliminary findings of investigations, initiated but not yet implemented during this period, are included. The results are based on the combined results of analytical developments, laboratory testing of pavement materials, an...

effects of geosynthetic reinforcement on the propagation of reflection cracking in asphalt overlays

an experimental program was conducted to determine the effects of geosynthetic reinforcement on mitigating reflection cracking in asphalt overlays. the objectives of this study were to asses the effects of geosynthetics inclusion and its placement location on the accumulation of permanent deformation. to simulate an asphalt pavement overlaid on top of a crack in a concrete or asphalt pavement, ...
