This technical data sheet provides information on Emulsion Bitumen Medium Setting 57%-K2. It is an asphalt emulsion where asphalt is milled into microscopic particles and suspended in water using an emulsifier. The emulsion has applications in surface dressing, tack coats, slurry sealing, and cold mixing. It has properties such as 57% residue by evaporation and positive particle charge. Safety precautions are outlined such as keeping it away from fire and cleaning skin contact with soap and water.

TECHNICAL DATA SHEET
Emulsion Bitumen Medium Setting 57%-K2
Description
When asphalt is milled into microscopic particles and dispersed in water with a chemical emulsifier, it
becomes an asphalt emulsion. The tiny droplets of asphalt remain uniformly suspended until the
emulsion is used for its intended purpose. In the emulsion state, the emulsifier molecules orient
themselves in and around droplets of asphalt. The chemistry of the emulsifier/asphalt/water system
determines the dispersion and the stability of the suspension. When emulsions are used in the field, the
water evaporates into the atmosphere, and the chemical emulsifier is retained with the asphalt.

Applications
 The four main application areas are surface dressing, tack coats, slurry sealing, and cold mixing.
 Surface Dressing Road maintenance technique, that involves the restoration of a
deteriorating road wearing course, before the main fabric of the road foundations are
irreparably destroyed
 Tack Coats Provide a thin adhesive film of bitumen between an existing road pavement and
overlay, or between courses in road construction.
 Overlay materials include hot rolled asphalt wearing courses and slurry seal. Tack coats are
also used in patching and inlay work, where further functions of priming and waterproofing
are necessary.
 Tack coat forms an adhesive and cohesive bond between the bituminous overlay and the
existing pavement, reducing the risks of slippage between the two courses, and allowing
traffic stresses to be distributed uniformly.
