Sub : UTWT at Bhosari colony in Pune city

Sir

The ULTRA THIN WHITE TOPPING (UTWT) which Pune Municipality is using for over lay to improve the damaged bituminous road is learnt by PMC Engineer along with contractor and consultant who visited our site in Thane which is developed by Dr.V.V.Deshmukh in consultation with Mr.P.Bongirwar. The same team have shown the successful demonstration to PMC engineer in Pune city.

Observing the performance of our work the Thane Municipality Corporation has sanctioned the budget of Rs 20 crores for UTWT to be used in city internal roads.

The present practice of that UTWT, which Pune Municipality Corporation is using, is not the correct technique and thereby not getting the expected benefits and this technique is optimised by us and proven from our experimental patch at Dahanukar Colony, Pune.
.
The following are the aspects that correct UTWT technology would help is
Cement use: one bag less per cubic meter which helps in reducing the carbon dioxide in the atmosphere and also the cost of surfacing. The idea of not using additive like fly ash, slag as substitute to cement is an old technique where as to achieve high strength we have to use this additive.
Use of fly ash: the fly ash, which is a by product of thermal power plant ,whose production of 100million tonnes per year and has problem of dumping., helps to be used as substitute to cement.
Process: the self compacted technique used by us in laying is faster and thus reducing times for unloading and completing the work faster. Use of machine






like vibrators for compaction is not required because of self compacting technique which is used by us. The mix which PMC is using is very harsh and takes two hours to unload where as our mix is semi self compacting and unloaded in half an hour.
The use of poly propylene strips helps to avoid cutting (1m X 1 m) , which results in less noise pollution and reduction of cost of Rs 100 per running meter.
The traffic can be opened in 72 hrs vs. 7 days, which reduces the inconvenience to pedestrians; less trouble to traffic diversion and traffic load to certain areas are avoided.
The above mentioned points are highlighted in light of correct UTWT technology which is today standardised by us
I also wish to highlight the following additional advantages of this UTWT technology.
Improved performance: The life of road is increased due use of UTWT than the bituminous road which saves maintenance cost and there is no rutting or wash boarding
In the recycle cost study it proves to be cheaper in the cycle of maintenance due to its longevity.
The light colour of the road increases illumino effect due to increased reflectivity and thereby reducing the heat content of the environment.
The less consumption of raw materials has direct bearing on the unit cost of the road surface laying.
Minimizes waste. Less material to landfill – most of the existing, worn asphalt pavement serves as a base for the UTWT, thus eliminating the need and expense to tear up and haul away the asphalt
Besides less cement consumption helps to earn Carbon credit and is lesser burden to environment.
Note: (1 ton of calcium carbonate the main raw product in manufacture of cement produces equivalent amount of carbon dioxide in atmosphere which is instrumental for global warming)
The world over to avoid the effect of global warming the use of flyash is giving the benefit if we can save carbon number.
In all the above mentioned contexts we should be given the chance to execute the above work in view of our experience in Thane and present work and the experimental patch at Pune.
