bitumen CRS1 CRS2 CRS producer and exporter in drum IBC tank

Bitumen K class like is similar to other ASTM grade Bitumen K170 (CRS1) Bitumen K160 (CRS) and bitumen K140 K 3 ( CSS) K2 (SMH1H) are equal emulsion bitumen.

One of the method for modifying bitumen is emulsification with water which enhance bitumen properties incredibly. Another advantages of modification is that it can be applied cold (80°C).

Emulsion bituminous asphalt consist of two immiscible liquids which are stabilized by emulsifier. They usually used for tack coats, hot-mixed asphalt, prime coats, chip seal. Firstly Anionic emulsion were developed and because cationic emulsion has more adhesion properties they are more favored especially in tack coating.

The type (chemistry) of the emulsifying agent used, determines the designation. During application, the water in a bitumen emulsion is either lost by evaporation, or it may separate from the bitumen because of the chemical nature of the surface to which the emulsion is applied. This process is referred to as breaking.

Depending on the type of emulsifier the bitumen particles can be both positive and negative. Emulsions in which the bitumen droplets are negatively charged are called anionic emulsions.   While, Emulsions in which the particles are positively charged are called cationic emulsions.

Bituminous asphalt emulsion K 170 , 160 ,140 ,  is a rapid setting cationic asphalt, which has positive charge leading reaction between the emulsion and pavement. It contains 67% bitumen . 1 denoted as rapid braking. The primer bitumen which is used for emulsification is obtained from crude oil.

The main applications asphalt emulsion K170 are surface treatment, sand seal and tack coat.

Dust control and base stabilizing by K140

bitumen emulsion is safe to use in dust and erosion control.

It is important to interrogate the life cycle of products used in dust and erosion control which starts by questioning the cradle-to-cradle journey of bitumen k140 emulsion from crude oil to application in dust and erosion control. To understand and fixate on the matter at hand we first need to understand what exactly bitumen emulsion is. But wait, the key word is bitumen so maybe we need to rewind and understand first what bitumen is. Indeed, without understanding the fingerprint of a material we might get oblivious of its post-use effect which we strongly believe is the case to those blindly using bitumen emulsion for dust and erosion control.

Uses of Cationic Bitumen Emulsion K160

Treatments and seals:

  • Single surface treatment
  • Multiple surface treatment
  • Sand seal

Penetration macadam

  • Small voids

* Bitumen K160 may be used as a tack coat in special cases where night construction or high humidity exists.

Cationic emulsions may be used at ambient temperatures with aggregates, which need not be completely dry. Emulsions are less hazardous to use and can be applied in a wider range of conditions.

Application of Cationic Emulsion Bitumen K170 (CRS1) K160 (CRS) K 140 K 3 ( CSS) K2 (SMH1H)

Emulsion Bitumen K160 cationic bitumen emulsion can be used at the ambient temperature at the spray rate of 0.25 to 0.70 litre per square meter (0.05 to 0.15 gallon per square yard)

Packing of Cationic Emulsion Bitumen K160

Bitumen Emulsion K160 is available in:

  • Bulk as IBC Tank, Flexi Tank
  • Reconditioned steel drums 200 lit.
  • New steel drums 200 lit.

Bitumen Emulsion is made up of three basic ingredients which include Bitumen, an emulsifying agent and water. Bitumen K 170 (CRS1) K 160 (CRS) K 140 K 3 ( CSS) K2 (SMH1H) containing minimum different percent of Bitumen, is commonly used for Tack-Coating. It is a medium viscosity cationic rapid-set bitumen emulsion used mainly for tack coating in normal overlay and patching work. Bitumen K 170 bitumen emulsion can also be used in grouting. Bitumen Emulsion K160 cationic bitumen emulsion is made according to KS 02-769: 1990 standard.
