Dilbit is a relatively clean bitumen (containing less than 0.5% water and solids) diluted with condensate, in the order of 20 to 40% by volume. Dilbit can only be processed through a high-conversion refinery, and is too heavy/sour for a simple refinery.
The grade of the bitumen depends on the amount of volatile material that remains in the product: the smaller the amount of volatiles, the harder the residual bitumen. Specialists in bitumen view bitumen as an advanced and complex construction material, not as a mere by-product of the oil refining process. Standard Bitumen Production Scheme
It can be used instead of 60/70 penetration bitumen grade. VG-40 BITUMEN. VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots instead of 30/40 penetration grade. Because of higher viscosity, stiffer Bitumen mixes can be produced to amend resistance to shoving and other problems related to higher temperature and heavy traffic loads.
Bitumen Penetration Grade 30/40 General description of Bitumen Penetration Grade 30/40. GJPco Bitumen Penetration Grade 30/40 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification.
Bitumen can be used in asphalt mix designs which result in the manufacture of cohesive asphalt mix with good elasticity suitable for type of heavy traffic intensity in terms of commercial vehicles. Further, optimum quality raw material and sophisticated manufacturing techniques is used in the production process of this range.

as pure bitumen sample, coarse aggregate mix, and fine aggregate mix were prepared. The effects of aging and curing process on compression strength of bitublock were found out by compacting the samples at 8-12 MPa pressure. The range of compressive strength during heat curing indicates the behavior of bitumen binder.
As the asphaltenes content reduces, the viscosity of bitumen also decreases. Aggregation is the factor that governs the viscosity of gel type bitumen. Gel type bitumen have a higher viscosity. Bitumen Structure Influence on Viscosity. Bitumen consist of resins, aromatics and some form of saturated oil after their manufacture.

BITUMEN BY-PRODUCTS Bitumen Bitumen is an oil based substance. It is a semi-solid hydrocarbon product produced by removing the lighter fractions (such as liquid petroleum gas, petrol and diesel) from heavy crude oil during the refining process.
Aug 06, 2018 · To making bitumen 90/15 or 85/25 distilled used oil or crude oil should be injected to product according to 20-25 % otherwise fragility in bitumen lead to inferior production. Increasing the heating temperature, air injection amount, time and tower pressure increase speed of production process reaction. Fine production temperature is 265-270°C.
