Bitumen 60/70, 85/100, 40/50
Bitumen is one of the derivatives of oil in black and pasty form, which has many applications in asphalt, road construction, insulation and roof waterproofing. This material has many types of its own and each one of them is used in different industries according to its unique physical characteristics. It varies as a hydrocarbon from black to brown and is completely soluble in carbon sulfide and carbon tetra chloride. This material is in solid shape in room temperature and ambient conditions and by increasing temperature, its shape will change to liquid and paste form. One of the main reasons for the diversity in its types is due to the existence of two significant properties in this material, including its permeability and adhesion.
Sulfur (Sulphur) Granule & Lump
Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and Egypt.
Natural Bitumen (Gilsonite)
This type of bitumen is a naturally occurring hydrocarbon that was first found in the Bonita River in northeastern Utah, which is hardened crude oil known as asphalt and euthanasia. This type can be soluble in aliphatic and aromatic solvents and is also used as a diluent for dilute petroleum derivatives due to its high compatibility
The emulsion contains a two-phase mixture in which the inner phase is dispersed in the form of fine particles in the outer phase. The diameter of these particles is between 0.1 and 5 microns and the diameter of the particles is larger than the true solution and colloidal state. The amount of emulsifier material used is between 0.3 to 0.5 percent by weight of Bitumen and the amount of water used is 30 to 50 percent. The emulsifier is usually an alkaline salt of organic acid or ammonium salt, which has a great effect on the charge of its particles
Cutback type is used in road construction because it is not possible to use it in solid form. This type is obtained by dissolving pure bitumen with oil and petroleum solvents. The quality depends on the quality of the pure bitumen, the amount and type of solvent. The degree of lubrication of this type depends on the amount of petroleum solvent in them, and the higher this amount, the higher its lubricity, and typically the amount of these solvents is between 10 and 50 percent.
