Comparison between various bituminous binders modified with crumb tyre rubber

2009

The aim of this paper is to show how the rheology, the performance and the storage stability of different bituminous binders, obtained from two bitumens with different asphaltenes content, change their properties when they are modified with recycled tyre crumb rubber. Physical, chemical and performance characterisation followed by rheological and storage stability analyses have been undertaken as the basis for the comparison. The results of the investigation indicate that bitumen with lower asphaltenes content is more influenced by the modification with the rubber. However, the modification of the bitumen with the higher asphaltenes content gives a binder with better performance and storage…

Quality-control procedure for dry-process rubberised asphalt mastics

2019

Crumb Rubber (CR) can be incorporated into asphalt mixes via the dry process by directly adding CR into the mixer together with other asphalt mixture’s components, or with the wet process where the CR is used as a bitumen modifier. While the wet process allows an accurate monitoring of the interaction between CR and bitumen, the lack of control represents a main issue in the dry process. In fact, in the latter the CR particles keep swelling during hauling and possibly also after paving operations, often causing workability issues and premature failures. This study wants to provide a methodology that could help quality control procedures of bitumen/filler/rubber systems during mixing, haulin…
