Investigating the Effect of Artificial Ageing on the Creep and Recovery of SBS-Modified Bitumen [PDF]

MATEC Web of Conferences, 2019
Polymer additives are widely used to improve the performances of road bitumen and mixtures including their oxidative resistance. However, their effect on the oxidative mechanism remains unclear. This study includes the investigation of the changes in the

Bitumens modified with recycled polymers [PDF]

Materials and Structures, 2000
Increasing traffic loading and volumes on roads has led to the use of polymer modified binders to improve the performance of bitumen in terms of additional strength, durability and increased resistance to rutting and fatigue cracking. Generally those modifiers currently in use are virgin polymers but the research investigates the possibility of using ...

Analysis of the Effects of Ageing on the Cohesive Strength of Polymer-Modified Bitumen at Low Temperatures

The Baltic Journal of Road and Bridge Engineering, 2018
The decay law on the ageing process of the cohesive strength of styrene-butadiene-styrene(SBS)- and polyethylene(PE)-modified bitumens at low temperatures was investigated. The rotated-thin-film oven test was used to age the two types of polymer-modified
