ROAD TECH TO WIPE OUT SKID RISK
NEW DELHI: Now there is a new technique available to wipe out
skidding risk on the roads. A go-ahead has been given by the
Central Road Research Institute (CRRI) to ecophalt
technology of South Korea.
will now be free to use this technology, besides the existing
ones, for any road construction across the country. The public
works department has already put it to use on a small stretch
or road at Dhaula Kuan (National Highway-8) on a trial basis.
to the Korean firm. Wooil Development Private Limited (WDPL),
which is liaising with Indian agencies, the ecophalt technology
is in use in over 10 Asian and European countries.
is called ecophalt because it claims to make porous
pavements (asphalt), ecologically compatible with all climatic
conditions. The technology has a special ingredient, drain asphalt-modified
additive (DAMA), which keeps the road dry even during the rainy
season or after a snowfall. It sucks surface water, drains it
out through pores and ensure fast-moving vehicles a skid free
drive, claim officials.
to the CRRI project leader (pavement design and analysis) Sunil
Bose Said: The institute carried out an eight-month-long
laboratory study to determine the compatibility of DAMA as an
additive in porous asphalt technology.
its certification, the CRRI had said: The porous asphalt
mixes are expected to find applications in India as high-speed,
high-density corridors (particularly the expressways) are gradually
becoming the order of the day.
In the past few months, WDPL had given extensive demos before
Delhi urban development minister A K Walia besides the citys
premier agencies PWD, DDA and Delhi State Industrial Development
Corporation. The agencies are however apprehensive about the
cost of ecophalt in India. The raw material, DAMA,
has to be imported from South Korea.
DDA engineer-member Prabhas Singh said: Cost-effectiveness
is definitely a bottleneck for this technology, since we have
many cost-effective roads already laid down. However, considering
transportation of raw materials from a foreign land and longevity
of the roads, one may not be so disappointed immediately, because
you can always start manufacturing DAMA here.
