Bitumen known as asphalt in parts of the world, is a hydrocarbon material. It has high viscosity and colloidal structure, and black to dark brown color. It's dissolvable in carbon disulfide and carbon tetrachloride.
It is impenetrable to moisture and water, electrical insulation, elasticity, moderate resistance against acids, bases and salts. Its adhesions to other materials are the most important features of bitumen.
Bitumen 60/70 is used for road construction projects in temperate regions. It can be used to produce some of the basic layers of asphalt and insulation.
Technical and grades specification are available upon request.

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.
Oxidized Bitumen is a type of Bitumen that obtains from blowing air to the Pure VB (vacuum bottom) Bitumen. Oxidized Bitumen has a lower penetration point and more softening point in comparison to VB. Based on its softening point and penetration points, it classifies into three types of low, medium and hard Oxidized Bitumen.
Oxidized Bitumen is well known by other names also as Blown Bitumen, Hard Bitumen, Blown Asphalt, and Oxidized Asphalt.
Process of Production of Oxidized Bitumen by Air Blowing
Process for the oxidation of bitumen, according to which a feed stream of bitumen and a stream of air or of another gaseous oxidizing agent are sent to a pressurized reactor, said reactor being a so-called rotary apparatus . The reaction between the gaseous oxidizing agent and the bitumen or other in the reactor is improved by generating turbulence by means of rotor-stator type mixing devices which produce shear forces making it possible to obtain a good dispersion of the oxidizing agent.
The Oxidized Bitumen is defined as follows: bitumen whose rheological properties have been substantially modified by reaction with air at elevated temperatures. Preferably, the oxidized bitumen has a softening point (ball and ring temperature) comprised between 85 and 95 C. The oxidized bitumen having a penetration at 25 C. of 5 to 15 mm are preferentially used.

Paint-like mixtures of gilsonite, solvents, and other additives are used to coat and seal asphalt pavements like driveways and parking lots. Gilsonite is also used as an adhesive and waterproofing agent in the manufacture of roofing felt. Addition of gilsonite makes some paint and wood stain formulations more durable.
