Crumb Rubber in cold recycled bituminous mixes: Comparison between Traditional Crumb Rubber and Cryogenic Crumb Rubber

Effect of crumb rubber gradation on a rubberized cold recycled mixture for road pavements

“…Furthermore a comparison study has been completed in order to understand the different effects of introducing cryogenic or ambient grinding rubber in a cold recycled mixture. The study confirmed that size distribution of the crumb rubber sample plays a significant role in the workability and mechanical properties [15].…”

Alternative Fillers for the Production of Bituminous Mixtures: A Screening Investigation on Waste Powders

“…The fillers used in this test are three different waste materials and one traditional limestone filler ( Figure 1). Within the current new awareness about ensuring better use of natural resources and recycling waste materials, a number of new experimentations have been carried out, over the past 20 years, to look at the possibility of replacing some of the natural components in the materials used in road construction with industrial by-products and waste materials from recycling processes [14][15][16][17][18][19].…”

Combining performance based lab tests and finite element modeling to predict life-time of bituminous bound pavements

“…Fatigue testing of asphalt mixes has been a major topic in pavement engineering in the last three decades [14,21,7,19,12,24]. Presently, a European Standard specifies the methods for characterizing the fatigue behavior of asphalt mixes by alternative tests, including bending tests and direct and indirect tensile tests, but without imposing a particular type of testing device.…”
