This paper proposes a simple mathematical tyre model that estimates tyre cornering stiffness. The model is derived by considering the tyre to be a combination of two independent systems. The sidewalls are assumed to be negligibly stiff in the lateral direction, and hence their influence on the lateral dynamics of the tyre will be ignored. The belt and tread area of the tyre will be considered t...

There are three types of adhesion difficulties faced by the Babylon Tyre manufactured: bonding the inner liner to the fabric cord, bonding the tread to the breaker bandage, and bonding the sidewall to the bead apex. We have investigated the adhesion between layers of tyre by using maleic anhydride (MA) in an elastomer while using phenolic resin, resorcinol, or novolak in another elastomer to un...

To provide an eco-friendly disposal way of increasingly accumulated waste tyres and reduce the environmental impact caused by production industrial fibres, this study explores feasibility using recycled tyre materials as substitutes for natural fine aggregates manufactured fibres in cementitious mortar. The effects crumb rubber (CR) replacement ratio (5%–15% volume aggregates), steel (RTS) fibr...

Roadways are considered one of the most important elements of infrastructure and they play an essential role in our daily lives. In road pavement construction, the use of crumb rubber in the modification of bitumen binder is considered as a smart solution for sustainable development by reusing waste materials. It is believed that crumb rubber modifier (CRM) could be one of the alternative polym...

background: production of solid waste is the result of the human’s different activities that today has changed a lot in comparison to the past due to the changing life styles and pervasive expansion. in isfahan province lots of wastes are produced daily. due to the importance of the waste and its recycling, the purpose is determining the production scopes of different wastes in order to find a ...

Lightweight concrete (LWC) is used in the construction of partition and panel walls framed structures because it reduces dead load acting on structure. Rubberized lightweight aggregate made by using waste rubber tyre chips as a partial replacement coarse which increases ductility, toughness minimizes impact effect concrete. The presence content decreases compressive strength bond strength, affe...

Recovery of fat-and-oil production wastes will reduce the technogenic impact on environment, as well involve them in a new cycle secondary material resource. As part solving this problem, possibilities using tyre reclaim and modified are considered. In course studies, industry wastes’ sorption characteristics determined, relation to oils static dynamic conditions, spent reagent reclamation ways...

The possible contribution to urinary mutagenicity of occupational exposures in the rubber industry was studied by assaying the urine concentrates of 72 workmen (44 smokers) employed in a tyre plant. Twenty three clerks (16 smokers) engaged in the administrative department of the same factory served as presumptive unexposed controls. XAD-2 resin concentrates of urine samples were assayed in the ...
