Rutting Resistance Potential of High Modulus Asphalt Concrete Pavements

rutting performance of polypropylene modified asphalt concrete

rutting in asphalt concrete is a very common form of distress in asphalt concrete pavement which unfortunately has been incurable to date. one of the prime reasons of rutting is attributed to the behaviour of asphalt binder at elevated temperature. this study has investigated the performance of polypropylene fibres modified asphalt concrete mix against rutting. two types of asphalt concrete sam...

Concrete Overlays as a Rehabilitation Option for Distressed Asphalt Pavements

ERDC/GSL TR-17-10 "Rutting Performance of Cold-Applied Asphalt Repair Materials for Airfield Pavements"

Cold-applied asphalt mixtures are often used for pavement repair, primarily because of the small quantities involved and/or the unavailability of hotmixed asphalt. These cold-applied mixtures have poorer rutting resistance than hot mix asphalt because additives, often solvent, are required to provide adequate workability for them to be placed at ambient temperatures. This study primarily evalua...

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...

Rutting Based Evaluation of Asphalt Mixes

Pavement rutting is one of the most common and destructive pavement distresses being observed in flexible pavements, which is primarily due to axle loads that exceed legal limit and high ambient temperatures, and also poor mix design is one of the cause of rutting. The drastic increase in traffic volume during last few decades has resulted in premature pavement failures of almost the whole road...
