BITUMINOUS EMULSIONS (RAPID SETTING, MEDIUM SETTING & SLOW SETTING)
[CODE NO. 3127]
Bitumen is the general them applied to any block, tarry substance occuring in nature or produced by heat
from petroleum coal, natural gas or certain other organic substances. the term `asphalt' refers specifically
to the black, solid or semi solid bitumens obtained from petroleum. Asphalts occur as natural deposits
or are obtained as a residue in the distillation of crude petroleum. This asphaltic residue is called pitch.
Natural deposits of asphalt were first used by ancient civilizations the waterproofing, preservation and
cementing properties of asphalt were well known, and asphalt was an important article of commerce in
the earliest known civilization that developed in Mesopotania, Egypt and the Indus valley with the passing
of these early civilizations, the use of asphalt tended to diminsh. However often 1900, due to the
discovery of large amounts of asphalt-base crude petroleum asphalt was obtained as a by-product of petroleum
refining.
Most bituminous binders used in the construction of roads are viscous semi solids at normal
temperatures. For surface dressing, therefore, they must be brought to a fluid state by heating before
being applied in this films to road surfaces. Similarly, in the preparation of coated macadam, both the
binder and the aggregate require heating to enable good coating of the stone to take place. The lack of
adequate heating facilities in remote areas led to a demand for binders which could be used cold. When,
for this purpose, volatile solvents were added to the binder, apart from their high cost, such binders
suffered the disadvantage that they had to be applied only to dry surfaces. The introduction of emulsions
over came this difficulty as these not only flow readily at atmospheric temperatures but can also be applied
to damp road surfaces and used for coating damp aggregate. Road emulsions are particularly,
suitable for the preparation of coated macadam in small batches, no preheating of the aggregate being
required.
