Petrocoke and extract-doped modified bitumen composition for use in production of asphalt and method of producing the same

摘要

A modified bitumen composition used in asphalt-coated roads as a binding raw material having petrocoke, a derivative of carbon based crude oil, and extract, a base oil unit by-product, as additives, and to a method of producing the same. The modified bitumen composition of the invention contains at least 55% by weight of bitumen with a penetration in the range of 40 to 110 as per EN 1426 standard, and 1%-40% by weight of petrocoke with a particle size preferably less than 300 micrometers, and 2% to 5% by weight of extract, a base oil unit by-product, as additives. Determination of the amount of the additives petrocoke and extract to be added to the bitumen, optimum values of such parameters as mixing temperature and mixing rate to distribute in the bitumen homogenously and the conditions at which the modified bitumen may be stored and/or transported without losing its improved properties.
