February 8-12, 2016 GRANADA Winter School Long term performance of low temperature asphalt mixtures containing reclaimed asphalt ESR3 Miguel Perez Martinez Supervisor: Paul MARSAC February 8-12, 2016 GRANADA Winter School

Figures from Google/images Introduction Asphalt is a mixture of aggregates, binder and filler, used for constructing and maintaining all kind of roads, parking areas but also play- and sport areas. Aggregates used for asphalt mixtures could be crushed rock, sand, gravel or slags. In order to bind the aggregates into a cohesive mixture a binder is used. Most commonly, bitumen is used as a binder. An average asphalt pavement consists of the road structure above the formation level which includes unbound and bituminous-bound materials. This gives the pavement the ability to distribute the loads of the traffic before it arrives at the formation level. Normally, pavements are made of different layers Figures from Google/images
