Feasibility of using waste Molecular sieve and Ceramic ball in hot asphalt mixtures

Environmental awareness about problems of industrial waste landfills has resulted in industrial waste management to be high on the agenda with an emphasis on the recovery of materials and energy. One of the methods of waste recycling in the oil and gas industry is the use of generated waste in civil activities. The main objective of this research is to assess the feasibility of using gas refineries industrial waste produced in dehydration unit in hot asphalt mixtures.
Material and The ICP and XRF analyses were carried out to determine the concentrations of heavy metals and composing elements of waste Molecular Sieve and Ceramic ¬ball. Sieve and and quality analyses were thence done on these wastes and materials. All stages of this research were conducted ethically.
Both types of wastes were classified as non-dangerous waste. Absorption of water in waste Molecular Sieve was at least 10 times the permissible level for aggregates according to the standards of Journal 234. Waste molecular sieve was not therefore replaceable with aggregates in asphalt mixtures since they may cause cracking in the winter season., Moreover, the existence of many pores in Molecular Sieve significantly increase the use of bitumen.
Waste Molecular Sieve is not recommend to be uses as an alternative to aggregates due to significant absorption of water.Furthermore, the comparison of results obtained from physical tests performed on the waste ceramics ball with standard limit of Journal 234 indicate the potential of this waste as an alternative to the aggregates in asphalt mixtures.
