Asphalt crumb rubber is a type of pavement material formed by mixing asphalt cement with that derived from recycled tires. This eco-friendly approach aids in waste reduction and promotes environmental preservation incorporating materials into construction. The study aimed to examine the behavior mixtures modified rubber, made blending tire-derived cement. Adding improved performance mixtures, 8...

Abstract In present day scenario the human activities have led to environmental degradation with increased urbanization contributing many fold increase in constructing activities, which uses limited natural resources. Therefore, prevention of resource over-utilization and recycling waste is utmost priority construction sector. Waste tires rubber one such potential material can be used concrete ...

The influence of different additives: high density polyethylene (HDPE), low density polyethylene (LDPE) and TiO2 nanoparticles on the polyethylene terephthalate (PET)–rubber nanocomposite interface was investigated. The composites obtained by compression moulding from tire rubber and PET bottles’ waste were partially heterogeneous and partially compatible, as confirmed by the FTIRmeasurements. ...

OBJECTIVES Workers in the rubber industry are exposed to a complex mixture of hazardous substances and have increased risk of developing several diseases. However, there is no up to date survey examining the exposure in the Swedish rubber industry. One of the toxic compounds in the industry is carbon disulfide (CS(2)), which is biotransformed to 2-thiothiazolidine-4-carboxylic acid (TTCA). TTCA...

We present a hybrid physical-dynamic tire/road friction model for applications of vehicle motion simulation and control. We extend the LuGre dynamic friction model by considering the physical model-based adhesion/sliding partition of the tire/road contact patch. Comparison and model parameters relationship are presented between the physical and the LuGre dynamic friction models. We show that th...

NONLINEAR DYNAMICS OF LONGITUDINAL GROUND VEHICLE TRACTION By Brian John Olson The purpose of this study is to investigate and understand the nonlinear dynamics of longitudinal ground vehicle traction. Specifically, the performance of rubber-tired automobiles under straight-ahead braking and acceleration conditions is discussed in detail. Two vehicle-traction models are considered—a quarter-car...
