Cutback Bitumen SC30
Rapid Curing 30 (SC30) combination of penetration grade asphalt cement and a diluent or cutter highly rapid in its volatility making it easier to apply. Cutback SC30is compliant with ASTM standard for cut back asphalt
Uses of Bitumen SC30
SC30 grade is used in the construction of roads and highways and for treatment for pavements in compliance with ASTM.SC30is also commonly used in spraying and for applications of mixing.
It is widely utilized in various construction applications due to its ease of use and effectiveness.
Priming Road Surfaces
The primary uses is for priming road surfaces before asphalt paving. It enhances adhesion between layers, improving the overall structural integrity of the pavement.
Packaging
SC30 is available in 1mm thickness steel drums or PE drums 200 KG Net Weight and 210 KG Gross Weight. It is also available in IBC containers
Cutback Bitumen – Slow Curing
SC-30, SC-70, SC-250, SC-800 and SC-3000
Slow Curing (SC) asphalt cement and oils of low volatility generally in the heavy distillate range (SC-30, SC-70, SC-250, SC-800 and SC-3000). The degree of liquidity developed in each case depends principally on the proportion of solvent to asphalt cement. To a minor degree, the liquidity of the Cutback may be affected by the hardness of the base asphalt from which the Cutback is made. The degree of fluidity results in several Grades of Cutback asphalt—some quite fluid at ordinary temperatures and others somewhat more viscous. The more viscous grades may require a small amount of heating to make them fluid enough for construction operations.
Slow Curing (SC) Cutback asphalts are often called road oils and are used primarily in road-mixing and dust-laying applications. This term originated in earlier days when asphalt residual oil was used to give roads a low-cost, all-weather surface. SC Cutback asphalts are also used for stockpile patching mixes, plant-mixed with graded aggregates and occasionally for priming.
What is Cutback Bitumen SC30
Cutback asphalt SC30 is a specialized type of bitumen dissolved in kerosene, extensively used in construction for its viscosity-reducing properties. This article will delve into the properties, uses, packaging, pricing, handling, and quality assurance of Cutback Asphalt SC30, providing a comprehensive overview for construction professionals and enthusiasts alike.
Properties of Cutback Asphalt SC30
Cutback asphalt SC-30 possesses several key properties that make it invaluable in construction projects.
Viscosity Reduction
The primary characteristics is its significant reduction in viscosity. This property makes it easier to handle and apply, especially when lower viscosity is necessary for optimal performance.
Adhesion to Chips
It enhances adhesion to chips in road pavements, improving bonding between asphalt layers and surfaces. This leads to a more durable and resilient road structure over time.
Durability
The volatile components in SC-30 evaporate gradually, leaving behind a durable surface that can withstand heavy traffic loads and environmental challenges.
Waterproofing Applications
SC-30’s waterproofing capabilities make it suitable for protecting structures such as bridges and parking decks, extending their lifespan by preventing water infiltration.
Filling Capillary Voids
Due to its low viscosity and excellent flow properties, SC-30 is ideal for filling capillary voids in asphalt surfaces, reducing moisture penetration and pavement deterioration risks.
Packaging and Quality Assurance
Typically packaged in thick steel drums to ensure safe transportation and storage. Rigorous inspections and testing maintain compliance with international quality and performance standards.
Pricing and Handling
Cost Factors
The pricing of SC-30 depends on factors such as market demand, raw material costs, and transportation expenses. Contractors often procure it in bulk to benefit from economies of scale.
Safety Precautions
When handling Asphalt SC-30, safety precautions must be followed, including wearing protective gear such as gloves and goggles, ensuring adequate ventilation, and avoiding direct skin contact or inhalation of fumes.
