Iso Gam, Waterproofing of buildings, which was traditionally done with asphalt and bitumen until the last forty years, with the advent of waterproofing and the advantages of this type of insulation, these insulations gradually gave way to these. Today, in most buildings, whether in the foundation stage or in the insulation of walls, services, and roofs, insulation is done with a layer of iso gum waterproofing.
According to zinc testers (or viscosity), it means: the penetration of a standard needle with a certain shape in millimeters under the effect of a load of 100 grams in 5 seconds in bitumen Which takes place at a temperature of 25 ° C. The obtained number indicates the permeability of bitumen
Bitumen production in according to three standard method (Blowing method ,Straight run method and Blending method) in Iran and other countries
The Air Blowing Bitumen is produced by process of vacuum Bottom (VB) and air in the reactor. and due to the control of the process conditions, different grades are produced.
Bitumen clasification according to various specification such as Penetration, Viscosity, Performane of bitumen in the road and ....
Bitumen Emulsions are Basically an O/W – Oil on Water Solution – A Dispersion of Bitumen Particles on Water, Stabilized with the Addition of Surfactants – Surface Active Agents – or Most Commonly known as Emulsifiers, that Will Permit the Bitumen to De Diluted in Water. They are Primarily Used for Tack Coats for use in Between Hot Mix Asphalt Lyers and Prime Coats for Thin Hot Mix Surfacing Layers or a Chip Seal Pavements.
Whatever the end use, application conditions usually require bitumen to behave as a mobile liquid. In principle, there are three ways to make highly-viscous bitumen into a low-viscosity liquid:
- Heat it
- Dissolve it in solvents
- Emulsify it
- Cationic emulsions
- Anionic emulsions
- Non-ionic emulsions
- Clay-stabilized emulsions
- Rapid-setting (RS)
- Medium-setting (MS)
- Slow-setting (SS)
CSS-1 emulsion bitumen is a cationic emulsion. CSS-1 bitumen emulsion is usually made by passing a mixture of hot bitumen and water phase between a rotating disk, cone or wheel and a stator. Asphalt CSS1 emulsion is a cation retardant bitumen emulsion containing 57% black bitumen and is made exactly according to ASTM D 2397M-13 standard.
