Bitumen 10.5 is also known as Boscan 10.9 in a high-quality heavy crude highly known and demanded in the world market for its high properties to be used as an asphalt base, with an APY of 10.5 and WT content with 5.4% average in widely used in Europe and Asia. The physical properties that distinguish this Bitumen, which is a Passed Crude, are its higher viscosity and density, as well as its molecular weight composition. Heavy Crude Bitumen from the Orinoco region of Venezuela has a viscosity of over 48,000 centipoise (10 Pa s) at 15�°C. A diluent is usually added at regular distances from a pipeline to facilitate its removal, circulation. In 2011, in the Orinoco Belt, a pilot project for alternating steam injection was started to improve the viscosity of crude oil, a technique that has increased the recovery rate to 40 percent, which was previously 20%.

Air blowing Bitumen is an extensively used process to upgrade and achieve specifications of final bitumen product. The air blowing process is accompanied by hardening of bitumen, with corresponding changes in chemical composition thereby yielding product having acceptable consistency and temperature susceptibility.
Gilsonite or Natural Bitumen by Monamorco is also known as Natural Asphalt, Asphalting, and is soluble in petroleum asphalt solvents. Gilsonite is used in the hardening of oil products and it is easily converted to powder form.Gilsonite Natural Asphalt , Natural Bitumen , Hard Asphalt or Hard Asphaltum is used as a performance-enhancing agent for asphalt mixes. Gilsonite-modified paving mixes achieve higher PG grades and incorporate perfectly into the asphalt blend with no need for high shear milling as is the case with many other modifiers.
Bitumen emulsions are usually dispersions of minute droplets of bitumen in water and are examples of oil-in-water emulsions.
The bitumen content can be varied to suit different requirements and is typically between 30% and 70%. The primary objective of emulsifying bitumen is to obtain a product that can be used without the heating normally required when using cutbacks and paving grade bitumen.
In the manufacture of bitumen emulsions, hot bitumen is sheared rapidly in water containing an emulsifying chemical (emulsifier). This produces very small particles of bitumen (the dispersed phase) dispersed in water (the continuous phase). The bitumen particles are stabilized in suspension and do not readily coalesce due to the presence of the emulsifier, which is concentrated on the surface of the bitumen particles.
During application, the water in a bitumen emulsion is either lost by evaporation, or it may separate from the bitumen because of the chemical nature of the surface to which the emulsion is applied. This process is referred to as breaking. Because bitumen has a density only slightly higher than water, sedimentation of the bitumen droplets in an emulsion during storage is very slow. Emulsions can usually be regenerated after long storage times by gentle stirring to re-disperse the bitumen droplets.
Standard Viscosity Grade Bitumen (AC-Grades), in which the Viscosity of the standard bitumen (asphalt) is measured at 60 C (140 F). RTFOT Viscosity Grade Bitumen (AR-Grades), in which the Viscosity of bitumen (asphalt) is measured at 60 C (140 F) after the roll on thin film oven test.
Viscosity grade bitumen have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen. In the Viscosity Graded Bitumen specifications further special emphasizes is placed on the Bitumen ductility.
Performance Grade (PG) bitumen is bitumen which is graded based on its performance at different temperatures. The Long-Term Pavement Performance(LTPP) has given certain algorithm to calculate the temperature of the pavement based on the temperature of the air above. From this, the highest and the lowest temperatures of the pavement is calculated and the bitumen that performs well in that temperature range is selected.
Penetration grading and viscosity grading are somewhat limited in their ability to fully characterize asphalt binder for use in Hot Mix Asphalt(HMA) pavement. Therefore, as part of the Superpave research effort new binder tests and specifications were developed to more accurately and fully characterize asphalt binders for use in HMA pavements. These tests and specifications are specifically designed to address HMA pavement performance parameters such as rutting, fatigue cracking and thermal cracking.
