The feasibility of using large rubber chunks from shredded tires as aggregates in coldmixes for road construction was investigated in this study. The research was directed toward development of a chunk rubber asphalt concrete mix design for low volume road construction using local aggregate, shredded tire rubber chunks and a cationic emulsion. A set of mixes using different combinations of chun...

This paper reports the pyrolytic treatment of granulated scrap tires (GST) in a pilot distillation unit at moderate temperature (550°C) and atmospheric pressure, to produce oil, char and gas products. Tire-derived oil is a complex mixture of organic C(5)-C(24) compounds, including a very large proportion of aromatic compounds. This oil has a high gross calorific value (∼ 43 MJ kg(-1)) and N and...

waste tires, rubbers, plastic and steel materials, normally produced in every society, enter the environment and cause serious problems. these problems may, to some extent, be reduced by finding applications for them in engineering, for example, they can be used for geotechnical applications as backfill material and solving problems with low shear strength soils. such materials may be subjected...

There are different types of pollutants that harmful to the environment, including smog, chemicals dumped into rivers, scrap tires, etc. The latter have particularity it is not possible recycle them manufacture new tires. In present work, hydraulic concrete plates added with waste tire rubber were manufactured modify their sound absorption capacity. It was found additions produce changes in den...

This paper discusses the recognition of raised alphanumeric markings on rubber tires for their classification. The main subject of this paper is the finding, separating, and recognizing the characters raised on rubber tires, which is different from the recognition of printed characters. The complter simulation result shows that the proposed system can be successfully applied to the industrial a...

Accumulations of unused plastic waste and wast tires pose a great threat to humanity. Despite the convenience benefits that products from these materials bring, their pollutes soils water bodies, atmosphere, poses human health. The problem is have long decomposition time, recycling requires significant economic resources well-established logistics. For example, more than 8 million tons enter oc...

Parachlorophenol has an extended usage in refineries, petrochemical industries, insecticide, and herbicide manufacturing industries. Tire a solid waste, which is disposed in large amounts each year, a large number of them in landfills can cause irreparable environmental impacts. Consequently lots of efforts were done to produce activated carbon from used tires. Activated carbon was made in labo...
