This study presents an alternative for the combined revalorization of two wastes with high volumes generation, such as end-of-life tyres and glass. The experimental grid considered analysis joint use crumb rubber glass powder in mortars. Crumb is analysed a sand replacement at 10% 15% percentages, while is'. cement, considering effect maximum size particles (38 μm 45 μm). results obtained show ...

Tests have been carried out to evaluate the performance, emission, and combustion characteristics of a single cylinder direct injection diesel engine fueled with 10%, 30%, and 50% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tyres through vacuum pyrolysis. The combustion parameters such as heat release rate, cylinder peak pressure, and max...

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...

Rubber friction is critical in many applications ranging from automotive tyres to cylinder seals. The process where a static rubber sample transitions to frictional sliding is particularly poorly understood. The experimental and simulation results in this paper show a completely different detachment process from the static situation to sliding motion under dry and lubricated conditions. The res...

In this paper the three dimensional dynamic analysis of vehicle motions is presented on the basis of the finite element method, therefore the distribution of elasticity and mass of the chassis and vehicle body is taken into account accurately. The mode superposition method is improved on the description of large horizontal displacements (in longitudinal and lateral directions), while the effect...

In this paper we propose a solution for the minimum-time control of a two-wheeled differentially driven mobile robot in the presence of slip between the wheels and the ground. Starting from the Lagrangian equations of the system a Newton-Eulerian model of the robot is obtained by adding longitudinal and lateral forces between the tyres and the ground, expressed by means of the Pacejka equation....

Recently, there has been much interest in using lubricated surfaces to achieve extreme liquid repellency: a foreign droplet immiscible with the underlying lubricant layer was shown to slide o at a small tilt angle<5. This behaviour was hypothesized to arise from a thin lubricant overlayer film sandwiched between the droplet and solid substrate, but this has not been observed experimentally. Her...
