Roads with out pot holes....?

It is not that we do not have good specifications. CRRI has done a lot of research for better roads. Some of the NHs, specially from Delhi, are witness to that. However, the state PWDs are loath to use the better specifications or engage honest contractors who will build to specs. Using the age old specifications give the PWD engineers to work in cahoots with small dishonest contractors and steal the money allocated for roads.

Proper preparation of subgrade and sub base courses with proper cross slopes and usage of either concrete or properly graded bitumen concrete with well designed wearing course can make the roads much better. We still use 80/100 bitumen, which is too soft for the usage. we need to use 60/70 bitumen in the right quantity (the contractors cheat on this) for the top courses.

All tender works to be binded with a clause that for a stipulated period of 2 - 5 years what ever type of damages arrises excluding vehicular accidents, has to be under taken free of cost by the contractor within a given period of time. And to get this implemented an amount of 15% of the total tender value to be with held by govt. (PWD) for the period 2-5yrs and the same has to be released only on completion of the period.

This will not only raise the quality of construction but also a fear would be established among contractor as well as the leasing authority to keep them out of malpractices.

In india there is lot of IRC specification for roads. But after every repair pot holes will be there after the monsoon. It should be studied throughly and develop a new specification that match with the requirement.

I think Government should change the replace old roads with new ones over a regular period of time. Say, after every 2 years the roads can be changed. In this way, not only roads will become more strong and holes will be repaired but the new holes won't come so early because of previously made strong bases of layers of roads...

The contractors dont heat the bitumen to the temperature to which it has to be heated i.e, 140-160 c. The temperature of bitumen is a critical factor.

Proper subgrade tests need to be done at regular intervals. Subgrade also has a major role in stiffness.

In US , roads are laid keeping in view the monsoon i.e, by collecting data from the rain guage stations for each and every state. But here.......

The govt thinks that constructing roads means just give TENDERS & then the person who wins the contract has made lots of......

All the contractors should work as honest quality minded person/companies,sothat only after 5 years after construction maintenance is required and that should also be done very honestly.

As far as IRC code is concern that if followed actualy then there will not be any requirement of changing,only addition of researches are required,

For bitumin there are researches done by adding some chemicals to give good results,apart from emulsion .

Main problem is subletting of contracts to small contractors to whom quality does not matter. But u may observe that these days numbers of pot holes had decrease its due quality controls checks. For proper road sub base is very improtant and good binding mixtures so that there is minimum damage due to rain with proper maintanance. We can also go for rubber mix buitmen for road.

For laying a good road with long duration lasting a sampling of soil from various places to be done before floating tender and the received submittals to studied well and the tender should be awarded to only such contracxtor who bind to the requirements. QA /QC from both sides to work and make their reports. If required third party inspection and certification to be implemented.

i agree with Mrs. Pragya Kothari for regular maintenance of roads.But i find roads are generally constructed without shoulders.Body without limbs.i appeal profeessionals to come up with specifications so that roads may not suffer for debility particularly in monsoon.

Concrete Roads are

1. Maintenance Free

2. Energy Saving - Less consumption of fuel

3. Environment Friendly - Flyash can be used.

4. Lesser Pollution - Due to faster movement of Vehicles

The pathetics conditions of any infrastructral projects is only beause in our country we can find good contractors but can never find good civil engineers...who are always ready to compromise with their conscience & engineering senses....lots of R&D works hv been done in the research laboratories bt nothing is practiced in the fields bcz of poor management & will power.....if we be able to execute half of the reseach results at site there shall be no potholes on the road..n no building shall collapse......

but who are responsible for poor conscience of civil engineers...right from the college days we are told that ohh u r civil engineer...definitely u will get lots of black money once u get job....like this everybody around the civil engineer tell the same & accordingly a mindset is created for earning bad money..and compromise with quality.....if by chance any new engineer tries to execute new trends at site then he is discouraged by seniors in such a way that...either he stops doing such things n join them or been killed...or leaving the job...bt he dosnt find a single person to stand by him.....the nexus of corrupt engineers is so strong that no body can break them......

further, at pwd levels the contractors available are either kith n kin of politicians or real goondas....so it realy becomes very dangerous to expect anythng from them......poor pwd engineers...they cant change anythng...........

so ultimate solution is so stop the contactorship system for small valued work and pwd departments should do them departmentally by employing their own manpower n machineries...so that role of small contractors shall be finished...for big valued projects tendering syatem should be followed..bcz big construction firms are nt that much morally down...n even role of consultants..may also help....but now a days consultants for construction projects are also being succeptible to corrupt practices like pwds.....

Roads are generally damaged due to stagning of water at various points. Hence proper removal of rain water should b planned. For example expressway can be taken where required slopes are maintain so that there is no water storage thus reducing water effect on bitumine.

Make officials, contractors etc pay for it. Sack them, debar them, penalize them. There can be no excuses to what went wrong.

Main problem for pot holes on road is mainly due to water stagnation if proper champher and drainage facilities are provided we can reduce pot holes
