Types of Bitumen Emulsion The bitumen emulsion is classified into two types: 1. Based on Setting Time When the bitumen emulsion is applied on the aggregate for the road works the water evaporates leaving behind the bitumen droplets. These droplets spread on the aggregate and bind with each other and gains strength eventually.

2 hot bitumen emulsion at a temperature between 70 and 80 °c is applied by the spray paver. 3 Paving of a binder or surface course starts. The bitumen emulsion "breaks" immediately as the hot asphalt causes the water to evaporate, leaving a firmly adhering film of bitumen.

tack coat, penetration coat or cover spray. The only provision was that the spray rate be critical to a certain type of texture depth by considering the recommended spray rates as given in Section 1. This, however, did not include prime coats, because a bitumen emulsion does not usually seep through the pores of a finished base course.

seize or shear the asphalt emulsion. • DO NOT apply severe heat to pump packing glands or pump casing. The pump may be damaged and the asphalt may become even harder. • DO NOT dilute rapid-setting grades of emulsified asphalt with water. Medium and slow setting grades may be diluted, but always add water slowly to the asphalt emulsion.
