Dear
Shri Gadkariji :
Please
take a few minutes to read my following blog
Just
try out COLD ASPHALT technology
on one stretch of 10 Km of any proposed highway , under supervision of
Civil Engineering Department of IIT - Mumbai
or VJTI ( where I was on its Managing
Council for over 25 years )
Ask
the concerned College to give you a detailed comparative report on :
*
Cost / Km
*
Time / Km

Keep Experimenting !
Shri
Nitin Gadkari likes to experiment and take the accompanying risks
He
is not afraid to stick out his neck for fear of it getting chopped off !
He
is not paralyzed into inaction by " fear of failure "
He
like to tell his officers ,
"
Forget the history - what is your problem ? "
Then
offers solutions such as :
*
Logistic parks around big cities to
decongest roads and reduce pollution
*
RFID sensor embedded vehicles paying toll amount
electronically without stopping / needing humans
*
E-rickshaws to be treated on par with petrol
driven rickshaws
*
By passing Bharat V emission standards to directly jump to Bharat VI standards for all vehicles
*
Introducing hybrid model of financing for
attracting private participation in Highway construction
*
Use of slag cement in construction of
highways ( use of waste by-products of Steel Industry )
Dear
Shri Gadkariji :
Allow
me to suggest use of " COLD ASPHALT
" technology for building new roads / filling pot holes
Use
of hot asphalt requires a very narrow temperature range within which it must be
spread on roads before rolling
Any
hotter and it will just stick to the roller . Any colder and it just won't set
It
is difficult to maintain such narrow range ( of temperature ) after asphalt
carrying truck travels hundreds of kilometers - even when that truck has a
heating jacket ( consuming lots of fuel ! )
If
solidified asphalt ( usually stored in steel drums ) is used at the
construction site , then it needs to be heated / melted locally ( usually by
creating a wood fire ) - causing pollution and consuming trees !
And
hot asphalt would just not adhere to a wet surface , rendering it useless for
use in monsoon - especially for repair of pot holes
" COLD ASPHALT " technology overcomes
ALL of these problems !
*
It consists of mixing water ( 90 % ) with hot asphalt ( 9 % ) in presence of a
specialty chemical ( 1 % ) , in a
very simple Mixing Machine which can be transported anywhere on a trolley
*
This liquid mixture can remain stored in steel drums at ROOM TEMPERATURE
for over ONE YEAR !
*
Drums containing liquid can be transported and stored at road construction sites
and COLD ASPHALT mixed
with sand / aggregates as and when required . No ripping / destroying of drums
and breaking of solid asphalt
*
There is no need for ANY temperature control as mixture / aggregate can remain
at AMBIENT temperature
*
Since Cold Asphalt is basically water ( 90 % ) , it is ideally suited for
filling wet pot holes or laying on wet roads
*
After laying / spreading , as soon as a heavy roller is driven over Cold
Asphalt mixed aggregate , chemical bond
between water and asphalt is broken due to heavy pressure and setting
process starts , causing the layer to
solidify .
Within a matter of MINUTES , regular traffic can flow over
the road ! or over the filled pot holes !
*
Use of Cold Asphalt technology results in a HUGE COST SAVING ( remember ,
it is 90 % water ! )
*
Cold Asphalt roads are much easier to repair , with no pollution , and very
little energy consumption
* Using Cold Asphalt technology, 3 machines ( leveller
/spreader/roller ) can lay 1 KM road in a day !
I
have personally seen NATIONAL HIGHWAYS being constructed with Cold Asphalt
technology in France , way back in 1988 !
You
may turn around and ask :
"
With these advantages , how come our PWD / Municipalities have not adopted this
revolutionary technology ? "
My
guess :
Because
those responsible for drawing up tender documents , insist on use of Hot
Asphalt !
And
you know , why !
