Description of Bitumen Penetration 60/70 Bitumen 60/70 in UAE is one of the most widely used penetration-grade bitumen grades, which has an excellent compromise between hardness and flexibility. It is produced by air-blowing vacuum bottom residues in the refinery and has a penetration value of 60 to 70 deci-millimeters (dmm) according to the ASTM D946M […]
Introduction Bitumen Penetration Grade 40/50 is a semi-hard penetration bitumen used extensively in heavy-duty road construction and infrastructural projects. Classified under ASTM D946M specifications, the grade penetrates between 40 to 50 dmm and has improved viscosity and deformation resistance. Because of its thermoplastic nature, Bitumen 40/50 melts at high temperatures and freezes at low temperatures, […]
General Description Bitumen 30/40 Bitumen 30/40 is a semi-hard penetration bitumen of grade bitumen that is derived from vacuum distillation of crude oil. It is viscous and durable and is primarily used in road construction and asphalt pavement manufacturing, especially where there is heavy traffic and high stress. This penetration grade bitumen softens at elevated […]
Description Slow Curing (SC) Cutback Bitumen is also referred to as a blend of asphalt cement and low-volatility petroleum solvents such as fuel oil or diesel. The blend reduces the viscosity of the bitumen, which is easier to use in cold weather or cold mix operations. “Slow curing” refers to the slow evaporation of the […]
Description of MC Medium Curing (MC) Medium Curing cutback bitumen is a solvent bitumen blend with a moderately volatile solvent, typically kerosene. It has widespread usage in flexible pavements for surface dressing, prime coating, tack coating, and cold mix asphalt. It possesses a medium evaporation rate with a balance between setting time and workability, which […]
What is Rapid Curing Cutback Bitumen? Rapid curing cutback bitumen is asphalt cement mixed with light, very volatile solvents such as gasoline or naphtha. The solvents reduce the viscosity of the bitumen, making it easier to apply at low temperatures. The most commonly applied grades of rapid curing cutback bitumen are RC-70, RC-250, RC-800, and […]
What is Anionic Bitumen Emulsion? Anionic bitumen emulsion is a water-born bitumen product with negatively charged stabilizers. Anionic bitumen emulsion is generally utilized in road building and maintenance due to the fact that it is eco-friendly, convenient to apply, and also compatible with alkaline aggregates. How Does Anionic Bitumen Emulsion Work? This emulsion is formed […]
What is Cationic Bitumen Emulsion? Cationic bitumen emulsion is a stable water dispersion of bitumen droplets with a positive electric charge. The positively charged emulsifying agents (e.g., NH₃⁺ groups) cause them to move towards the cathode when under an electric field, hence the term “cationic.”They repel one another due to the charge and stay suspended […]
General Description Polymer Modified bitumen (PMB) is one of the specially designed and engineered bitumen grades that are used in making pavement, roads for heavy-duty traffic, and home roofing solutions to withstand extreme weather conditions. This material is also used as a sealant in residential roofing applications. consists of bitumen blended with a synthetic polymer […]
