Due to their environmental advantages, crumb rubber modified asphalt binders constitute an interesting alternative conventional for road surfaces of a more durable and sustainable nature. However, in practice, they remain less commonly used than polymer binders. This research aims study the real ageing during service lives when exposed various factors, including temperature gradients, presence ...

In this investigation, rheological properties of three different polymer-modified bitumen compounds containing recycled polyethylene terephthalate (R-PET), crumb rubber (CR) and poly (styrene-butadiene-styrene) (SBS) are evaluated and compared. The modified samples were tested by a dynamic shear rheometer (DSR) where complex modulus (G*), phase angle (δ) and rutting resistance (G*/Sinδ) of spec...

Cereal Chem. 69(5):495-501 Sodium stearoyl lactylate, sucrose monopalmitate, diacetyl tartaric acid the height of the plateau before the viscosity onset. The plateau was esters of monoand diglycerides, monoglycerides, and petroleum etherformed by progressive lowering of the initial viscosity, presumably caused extracted flour lipids were added to a bread formula at the 0.5% level by amylopectin...

The utilization of reclaimed asphalt pavement (RAP) contributes significantly to reducing resource waste and protecting the environment. However, due performance rejuvenator, fatigue cracking has always been one important constraint on development pavements. Based studies previously conducted by our group, this paper investigated properties rubber/oil (WRO) rejuvenated common dynamic shear rheo...

This paper presents the results of a study strength and thermal properties concrete in which part fine coarse aggregate was replaced with crumb rubber from used tyres up to 2.4% weight concrete. Twelve series w/c = 0.45 0.55 were tested. A decrease compressive linear dependence relation amount observed. At same time, insulating material improved, also depended linearly on dosage range applied. ...

Crumb rubber (CR) derived from grinding of end-of-life tyres (ELTs) may be successfully used as a bitumen modifier or as a supplementary component in the production of bituminous mixtures employed for the construction and maintenance of road pavements. However, CRs deriving from different sources and production processes yield effects on performance of corresponding paving mixtures under traffi...

Background The modification of asphalt binder to improve performance properties has grown significantly since the implementation of the Strategic Highway Research Program (SHRP) binder specifications. There has been increased use of polymers, crumb rubber modifier and Polyphosphoric Acid (PPA). There has been concern by many highway agencies about the performance characteristics of PPA modifica...

In this research, the efficiency of Recycled Glass Powder (RGP) is evaluated for improvement of polymer-modified bitumen and asphalt mixture performance. An extensive laboratory programm was undertaken for polymer-modified bitumen including Crumb Rubber (CR), Styrene Butadiene Styrene (SBS) and Styrene Butadiene Rubber (SBR). Rheological and mechanical proper...
