CUTBACK BITUMEN RC-70

INTRODUCTION OF CUTBACK BITUMEN RC-70

Cutback bitumen RC-70 is a widely used product in road construction and maintenance. It is a type of bitumen that has been dissolved in a petroleum solvent, making it easier to handle and apply. This page will explore various aspects of cutback bitumen RC70, including its history, production, chemical formula, properties, advantages, safety tips, factors affecting its price, applications, packaging, transportation, and storage.

Cutback bitumen RC-70 Brief Description

Cutback bitumen RC-70 is a black, semi-solid material that is used in road construction and maintenance. It is made by dissolving bitumen in a petroleum solvent, such as kerosene or diesel oil, to create a liquid that can be sprayed or poured onto road surfaces. The solvent then evaporates, leaving a solid layer of bitumen that adheres to the road surface. Cutback bitumen RC 70 is commonly used in warm climates where rapid evaporation of the solvent is required.

What is the Cutback bitumen RC-70?

Cutback bitumen RC-70 is a type of bitumen that has been mixed with a petroleum solvent to make it easier to handle and apply. Bitumen is a sticky, black, and highly viscous liquid that is a byproduct of crude oil distillation. It is commonly used in road construction and maintenance to provide a durable, waterproof, and skid-resistant surface. However, bitumen is difficult to handle and apply in its pure form, so it is often mixed with a solvent to create cutback bitumen.

Cutback bitumen RC-70 History

The use of bitumen in road construction dates back to ancient times, when it was used as a binding material for stone pavements. The first modern road constructed with bitumen was built in Paris in 1852. Over time, the use of bitumen in road construction became more widespread, and different types of bitumen were developed to meet specific needs. Cutback bitumen was first developed in the early 1900s as a way to make bitumen easier to handle and apply. The use of cutback bitumen became more widespread in the mid-20th century, with the development of new production techniques and the growth of the road construction industry.

Cutback bitumen RC-70 Other Names

Cutback bitumen RC-70 is also known as rapid-curing cutback asphalt or cutback asphalt RC-70. It is sometimes referred to simply as RC70 or cutback bitumen.

Cutback bitumen RC-70 Production

Cutback bitumen RC-70 is produced by mixing bitumen with a petroleum solvent, such as kerosene or diesel oil. The ratio of bitumen to solvent can vary, depending on the desired viscosity and curing time. The mixture is typically heated to around 150-180°C to facilitate mixing, and then allowed to cool to room temperature. The resulting product is a liquid that can be sprayed or poured onto road surfaces. Once the solvent evaporates, a solid layer of bitumen remains.

Cutback bitumen RC-70 Specifications

Cutback bitumen RC-70 Chemical Formula, CAS Number, and HS Code

The chemical formula for bitumen is CnH2n+2, where n is typically in the range of 20-40. Cutback bitumen RC-70 is a mixture of bitumen and a petroleum solvent, so it does not have a specific chemical formula. However, the solvent used in its production can vary, and may include kerosene, diesel oil, or other petroleum distillates. The CAS number for bitumen is 8052-42-4, and the HS code for cutback bitumen is 2714.10.00.
