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. ...

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...

After 1860’s the railway systems has started to be used in urban transportation in the world. However, especially after the 1950’s, automobile usage has been increased quickly. Thus the dense of transportation has started to move from railway systems to the ones with rubber tire vehicles in Istanbul. Traffic density in urban transportation has started to be experienced since 1950 with the incre...

DEFINITIONS NOTE: These definitions are for your general use and may differ from those applied by various recyclers. Verify the meaning of terms with the respective recycler. APPLIANCES/WHITE GOODS: Refrigerators, washers and dryers, and other household machinery with mostly metal content. Scrap metal dealers are not interested in appliances primarily composed of plastic. BALE: A densified and ...

For the design of an antenna that will be directly attached to a car tire, the proximity effects due to the tire have to be considered. Measurements are performed on a dipole antenna that is mounted at the inside of the tire tread to determine the change in input impedance and resonant frequency caused by the dielectric rubber material and the metal reinforcement of the tire. A differential mea...

The major chemical changes during the processing of rubber occur with the breakdown in mastication and during vulcanization of the molded tire. There is little chemical change during the compounding, calendering, extrusion, and molding steps. Reclaiming is the process of converting scrap rubber into an unsaturated, processible product that can be vulcanized with sulfur. Pyrolysis of scrap rubbe...

Because tires contain approximately 1-2% zinc by weight, zinc leaching is an environmental concern associated with civil engineering applications of tire crumb rubber. An assessment of zinc leaching data from 14 studies in the published literature indicates that increasing zinc leaching is associated with lower pH and longer leaching times, but the data display a wide range of zinc concentratio...

Materials such as waste tire chips were widely used to improve the strength of soil. The objective of this study is to discuss the residual strength or steady-state behavior of sand-waste tire chip mixtures. A series of undrained monotonic triaxial compression tests were conducted on reconstituted saturated specimens of sand and sand-tire chip mixtures with variation in the tire-chip contents f...
