The failure of bonding between asphalt and aggregate is called stripping. Loss of
bonding results in lowered performance.
The following five primary mechanisms that either individually or together cause the debonding
of asphalt from aggregate.
1. Detachment which is the separation caused by water of the asphalt film from the aggregate
without any visual break in the asphalt firm.
2. Displacement which results from the intrusion of water to the aggregate surface through a
break in the asphalt film or through the film itself.
3. Spontaneous emulsion which is the formation of a inverted reversible emulsion at the
aggregate.
4. Pore pressure which is the increased pressure caused by circulation of trapped water
through the void structure of the aggregate.
5. Hydraulic scouring which occurs on surface courses because of a compression tension
cycle caused by the interaction of tire pressure with surface water.

Of the different ways to minimize the effect of water on the pavement liquid
Antistripping agents are frequently used.
It has been observed that the natural stone aggregate normally used for road construction and
surface treatment generally do not conform to the stripping requirements viz. 5% (maximum)
specified by Indian Roads Congress – Most of the stones in Indian States have been found to show
a very high stripping value ranging from 20% 90% when tested by standard methods. The fact
further necessitates the adoption of suitable measure to reduce the stripping to at least permissible
limits, when exposed to moist conditions. Incorporation of 0.3 to 1% BITUBUILD in the bitumen
binder used for coating such defective stones reduces the stripping not only to permissible limits
but to almost nil.

Advantages of using BITUBUILD are.

• BITUBUILD lowers the surface tension of bitumen and makes the binder stick firmly even to wet aggregate and resistant to stripping action of water. It, therefore, makes it possible to paint the wet the road surface immediately after the construction of Water Bound Macadam.
• BITUBUILD improves the workability and spreading/penetrating power of the binder and thus promotes smooth and stable coating of the stone aggregate.
• By its virtue of chemical composition. BITUBUILD concentrates in the surface layers and thus prevents stripping of the binder both at the aggregate binder and the road binder interphases. Thus the binder containing BITUBUILD holds the road surface and chippings together with a formidable grip.
• Use of BITUBUILD is very cost effective, as very small quantity is required to get satisfactory results.
• Anti-stripping effect of BITUBUILD is lasting and it therefore considerably prolongs the life of surface treatment, besides preventing reveling in the freshly surfaced roads.
• BITUBUILD improves the wet strength of the bituminous surfaces.
• BITUBUILD makes the binder stick to a wet road and thus makes the surface dressing possible even during wet weather and thus extends the road season.
• Action of BITUBUILD is quick and road may be used by traffic immediately after surfacing has been completed.
• BITUBUILD prevents the formation of pot holes in the road surface and thus facilitates its smooth performances resulting into convenience to traffic besides saving of expenditure and time on frequent repairs.
• BITUBUILD reduces the wear and tear of vehicles by helping in smooth performance of the road surface.
• BITUBUILD helps to start the surface dressing work even in the morning hours.
• Using BITUBUILD is not a minor improvement to surface dressing technique. It is a revolution
