An
anti-stripping agent is one, which can help in stopping the water molecules
from damaging the adhesion between two surfaces such as the bitumen and the
aggregates below it. Using such agents can help in better pavement or road
quality.
One of the major
problems that a construction worker faces, when paving a way or an asphalt roadway, is the percolation of water and its
affinity to the aggregates below the bitumen. The stone, sand and the mixture
which is present below the asphalt, absorb water, to become lesser in its consistency.
With the
aggregates accumulating water, the bitumen or the solid surface that is laid on the top of the stones, do not
stick according to the standards. This results in a road that is not strong enough to withstand weather
conditions or wear and tear.
One might very
often see the upper bitumen in roads separating
out of the lower layer or the layer becoming loose in some places. This is the
result of stripping phenomenon of water.
However, thankfully, with the innovative technology, we now have an
excellent agent, which can help in stopping of this stripping by water. Thus,
with less water affinity, the aggregates stick to the bitumen surface,
resulting in better roads.
These anti-stripping agents are also called as
adhesion promoters since they help in
enhancing the adhesion of the surfaces. The best part of such chemicals are
that they are easier to handle and can be mixed
quickly and efficiently. With the
outstanding results, they render, the
anti-stripping agents form
one of the major requirements of the construction industry today.
Such
anti-stripping agents not only control the water activity while building of the
roads, but also can act efficiently long after the roads are constructed,
making it a very cost-effective option.
