TIKI EMULSIFIED BITUMEN

IS : 8887 : 2004 (ISI MARKED)

TikiBitumen Emulsion is available as Anionic,Cationic and Nonionic types. Usually, it is the type of aggregate and climate that defines what type of Bitumen Emulsion should be used. Cationic Emulsion represents more than 95% of the world Consumption today.

The technology for the emulsion chemistry and type of application equipment make it the most logical class of emulsion to use, especially in case of tropical countries and countries with extreme climatic conditions.

The application advantages of Cationic Bitumen Emulsion depend on coalescence of the Bitumen droplets when they contact aggregate or road surfaces. Such coalescence is called breaking.Emulsions are broadly classified according to the speed with which they break when contacted with aggregate.

Rapid Setting Emulsion (RS}:

Break is rapid even with coarse aggregate of relatively low surface area. Rapid setting Emulsion is further sub divided into RS-1 and RS-2 types.

Medium Setting Emulsion (MS}:

Break is sufficiently slow that the emulsion can be mixed with coarse aggregate containing a high proportion of fine material.

Slow Setting Emulsion (SS}:

Break is sufficiently slow to allow mixing with aggregate containing fine material of relatively high surface area.Slow setting emulsion is further sub divided into SS-1 and SS-2 types.
