Introduction Sulfonated asphalt, a chemical modification of bitumen, has great importance in the oil and gas industries, particularly in the formulation of drilling fluid. Its role is manifold: enhancing shale stabilization reducing fluid loss providing lubricity Starting with oxidized bitumen, the chemical and physical transformations through which such desired properties are developed are explained in […]
Descrição do betume oxidado Os graus de betume oxidado ou betume soprado são produzidos pela passagem de ar pelos graus de penetração. Isso dá ao betume mais propriedades de borracha, tornando-o mais duro. Além disso, sob condições controladas de temperatura, o betume duro é usado como camada antiderrapante na indústria de estacas, na produção de […]
Australian Grade Bitumen C600 Description Australian Grade Bitumen C600 is a highly rigid bitumen grade with the ability to resist extreme stress and high temperatures. It is ideal for very severe environments such as major highways, industrial roads, and areas exposed to high-intensity heat and heavy traffic because of its stiffness, which provides superior resistance […]
Description Australian Grade Bitumen C450 is specifically engineered for high-stress areas and regions with intense heat. Engineers use this bitumen to construct asphalt pavements for roads, crossings, and industrial zones. Due to its high viscosity, C450 resists softening and deformation. As a result, it performs exceptionally well in areas with heavy traffic and high temperatures. […]
Australian Grade Bitumen C320 Description Australian Grade Bitumen C320 is commonly used in high-traffic asphalt pavements due to its high viscosity and tolerance to fatigue, making it suitable for high temperatures and traffic loads. Because of its high viscosity, Bitumen C320 is used in the construction of highways and expressways with heavy traffic. In compared […]
Description Australian Grade Bitumen C240 boasts excellent weather resistance, accompanied by strong adhesion. Also, bitumen grade C240, when compared with grade C170, demonstrates the excellent behavior of bitumen against being squeezed in hot asphalt pavement mix for roads carrying medium to low traffic volumes in areas experiencing higher ambient temperatures. Conclusively, such a high viscosity […]
Description Australian Grade Bitumen C170 is a standard viscosity-grade bitumen used in road construction and other applications of asphalt. It is produced according to Australian Standards (AS 2008-2020) and is intended for applications that require moderate stiffness. C170 bitumen has a penetration value of about 60-80 (measured in tenths of a millimeter) and a viscosity […]
Description of Cutback Bitumen SC-3000 Cutback Bitumen SC-3000 is an SC anionic bituminous product which is primarily employed in road surfacing and surface treatments like chip seals and dust control for unpaved roads. It is produced by blending a heavy industrial solvent (such as black oil or diesel) with pure bitumen, reducing its viscosity and […]
Description of Cutback Bitumen SC-800 Cutback Bitumen SC-800 is a slow curing cutback bitumen, made by dissolving penetration grade bitumen in a petroleum solvent, typically kerosene or diesel. This reduces the bitumen’s viscosity, making it easier to handle and apply. Cutback Bitumen SC800 has a kinematic viscosity ranging from 800 to 1600 centistokes (CST) at […]
Description of Cutback Bitumen SC-250 Cutback Bitumen SC-250 is a slow-curing asphalt used in pavement construction and treatment. It is composed of penetration grade asphalt cement and a slow-volatility diluent or cutter, meeting ASTM D2028-97 specifications. SC-250 and SC-70 are cutback asphalts that resemble residual refinery products, commonly used as heavy fuel oils. They are […]
