Asphalt Oil

Asphalt Oil Definition

Asphalt-Base Oil is crude oil that has asphaltum in large amounts making it highly viscous and heavy in nature. Such type of crude oil contains 2% less wax in the residue obtained after the distillation process. This crude oil is sticky and in a semi-solid or liquid state. Asphalt-base oil is separated from the crude oil through a distillation process whereby it is removed from the higher-boiling hydrocarbons. The byproducts of such crude oil are bitumen, petroleum asphalt or asphalt.
Other Name: Bitumen Oil

Iran is a big producer of Asphalt oil in Middle East and ZUMRUT has a big share of this production.

Asphalt oil, also known as asphalt cement or bitumen, is a highly viscous, black, sticky substance derived from the distillation of crude oil. It is primarily used in road construction and roofing due to its excellent adhesive and waterproofing properties.

Characteristics of Asphalt Oil

  1. Viscosity : It is highly viscous, making it an effective binder for aggregates in road construction.
  2. Adhesive Properties : Asphalt oil strongly adheres to surfaces, which is crucial for its use in paving and roofing.
  3. Waterproofing : It provides an effective barrier against water, making it ideal for waterproofing applications.
  4. Temperature Sensitivity : Its viscosity decreases with increasing temperature, allowing it to be easily applied when heated.
  5. Durability : It is resistant to weathering and can withstand the stress of heavy traffic and environmental conditions.

Applications of Asphalt Oil

  1. Road Construction : Used as a binder in asphalt concrete for paving roads, highways, and runways.
  2. Roofing : Utilized in the production of roofing felt and shingles, providing waterproofing and weather resistance.
  3. Waterproofing : Applied in various waterproofing systems, such as foundations, basements, and reservoirs.
  4. Sealants : Used in the manufacture of sealants for pavements, joints, and other construction applications.
  5. Protective Coatings : Employed as a protective coating for pipelines and other structures to prevent corrosion and water infiltration.

Asphalt oil is a vital material in construction and infrastructure projects, offering a combination of adhesive strength, durability, and waterproofing capabilities.

Safety & Health

People can be exposed to asphalt in the workplace by breathing in fumes or skin absorption. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit of 5 mg/m3 over a 15-minute period.

Asphalt is basically an inert material that must be heated or diluted to a point where it becomes workable for the production of materials for paving, roofing, and other applications. In examining the potential health hazards associated with asphalt, the International Agency for Research on Cancer (IARC) determined that it is the application parameters, predominantly temperature, that affect occupational exposure and the potential bioavailable carcinogenic hazard/risk of the asphalt emissions. In particular, temperatures greater than 199 °C (390 °F), were shown to produce a greater exposure risk than when asphalt was heated to lower temperatures, such as those typically used in asphalt pavement mix production and placement. IARC has classified asphalt as a Class 2B possible carcinogen.
