1. BACKGROUND During the late 1960’s and early 1970’s German scientists began experimenting with emulsion/aggregate mixes to find a way to use stable, thicker applications which could be applied in narrow courses to fill wheel ruts, without destroying expensive road marking lines on the autobahns. They found that if carefully selected aggregate was combined with […]

BITUMEN EMULSIONS Background of bitumen emulsion development On 9 May, 1922, an English chemist, Hugh Alan Mackay, filed a patent for the production of bitumen emulsion. He claimed in his patent application that a stable dispersion of bitumen in water can be obtained if the bitumen is dispersed with high shear in water containing a […]

THE BASICS OF COLDMIX
Cold premixes can conveniently be prepared with bitumen emulsion because the binder is already in a highly dispersed state. This property also renders emulsions very suitable for the preparation of premixes with simple equipment such as concrete mixers and even a shovel and a staging board. The following range of emulsions is available: Anionic Stable […]
