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 !
