Introduction Cold asphalt is one of the major materials for road construction and repair works, especially in the case of relatively low traffic or under temporary repair conditions. Unlike the traditional hot mix asphalt, cold asphalt can be laid without heating or any specialized equipment at ambient temperatures. One of the most critical components in […]
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 […]
Description of Cutback Bitumen SC-70 Cutback bitumen SC-70 is a mixture of bitumen and kerosene, used to reduce the viscosity of bitumen in road pavements. This reduces the bitumen’s viscosity, aiding in the construction of seal coats. The cutback agent evaporates from the seal coat, becoming a negligible component a few months after application. However, […]
