MY TAKE :
Dear
Shri Chahal : Please consider COLD ASPHALT………………. 12 July 2022

Dear Shri Chahal,
I urge you to
get the experts at the Indian Road Congress to examine the
feasibility and economics of using COLD ASPHALT , as suggested in my
following 6 YEAR old
email :
Ø Keep Experimenting ……………………………[ 21 Feb 2016 ]
Extract :
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 kilometer - 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
No ripping / destroying of drums and breaking of solid asphalt
* There
is no need for ANY temperature control as
mixture / aggregate can
remain
*
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
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 !
With regards,
Hemen
