The practice is to use a lower water-cement ratio making the concrete mix a little stiff(and not slippery) with higher compressive strength (minimum of 30N/m^2) achieved.

Nice one bro,e be like say u get A1 for strength of materials when u dey uni

TimeMachine:


You dey mind them ?

But the technology is good, but the governor is supposed to do a better job. Drainage is needed, and all he needed was to replace butimen with cement and construct a nice road with gutter. But he bleeped up in attempt to show the 'thickness' of the cement to justify his inflated budget.

I love politicians, because they can lie, and steal without being jailed. I will like my kids to be politicians, but for me, I have politicians in my pocket.

Stop deceiving yourself that a drainage must necessary exist in road construction especially for concrete asphalt roads or pure concrete roads.


Do you know that the thicker a road is, the more difficult it will be to erode it especially when it is not being covered by water and the edges are reinforced with concretes in order to prevent water from washing away the soil on which it was built on.


Besides, a concrete road is like a rock that water can not break up.

The road is usually very slippery when it's raining....though it's still under construction cus it'll still be asphalted,a drainage system constructed coupled with the side-walks too.

I've been on Nairaland since 2006!
I am a well seasoned and practiving engineer. I have travel to 4 continents and tens of countries . I celebrate success when I see it. I am no empty barrel. Mediocrity is what I don't tolerate.

We have all seen your CV. Now answer the question I asked.

bixton:



Apologies but please kindly check the tyres of your friend if they are not yet expired. Check the expiration code by the sides.

Concrete roads are done in most communities in Bayelsa State. So it's not new.
They should just ensure that the surface is not too smooth.

The only problem I have with this road as shown on the pix is that the sides are exposed. They should use sand/laterite to lap the sides of the concrete so it does not wear out too soon.

If only flyca can understand



Fawklicant , pls ignore flyca.

Jos lukat the nonzenz!
So this is what we are suppose to be celebrating in Nigeria OP! This road is death trap!

Any road less than 50km is not worth celebrating!

Any road less than 200meters width, with no corridors, no side walks, no streetlights, no interchanges, no highway direction boards, no road markings, no pavements, no drainge is not news worthy!

OP, This is 21st century. Building a road is no innovation. The internet is a very broad network consisting of millions of users within and outside your narrow brain range. Please stop disgracing us!

Mr. 21st century standards, that is clearly an inter City link road. Winding through remote areas, linking cities together.
You don't build side walks and street lights on inter cities or inter state roads
Side walks and street lights for who exactly??
Interchanges?? To divert what traffic??

EternalTruths:

Good advice bro!

This is a waste of money, I can assure anybody of that. Give the road 2 years and come back with report.

Lucky Igbinedion did this cement road project close to my house at uwelu Benin city, it was a waste of money.

Are you daft or are you just trying?
This road is not news worthy! If it's a village road, then that gives the governor right to build it anyhow? No side parking pavements, no railings, no streetlights, no markings because it's a village road? You guys are just annoying! So why bring “a village road” to NL to celebrate?

Even if the governor wants let him build with his spit! It's his job as the governor. We cannot be celebrating road as achievement in 21st century. Get sense or get out! You and that Fawklicant!

KunAviero:
Yeah, President Buhari was talking with Dangote about building roads with concrete some years back. I wonder what happened to those talks.

I think if d road is not constructed along residential area or structure around it ...it of no paramount importance

I don't know you....
But your school fees is well invested.

the guy is smart...better nigeria replace all asphalt streets with concrete streets.....asphalt streets is not good for nigeria.....

concrete streets may crack but can be repaired easily.....

just keep on feeling the cracks with wet concrete.....

it will last very long.....

dont let whites deceive you with asphalt streets...aspalt streets need too much maintenace....

concrete streets is best for a culture that only understand to build and forget.....

i am a construction worker as profession and i can definitly tell you concrete streest are better for rough enviroment...

and we produce cement in hugh amounts anyways....

you blacks have to learn to keep whites out of your internal matters....

you people cant even breathe without consulting whites...its foolish...you have already black engineers....

use them...!!!!

Kudos to Gov. Umahi. Most governors will NOT use this road building technology because, they MUST do roads every 2-3 years in order to embezzle government funds and deceive the poor masses. Most governors in Nigeria have no tangible developmental projects to showcase other than roads, more so poorly built roads. Is all about governance in building roads? Human Capital development is one of the vital projects any reasonable government should embark on.

you dont need expats for anything....

nigerians are smart enough to do everything themselves....

Just like I thought.

expat my foot....

What was your question? In case I skipped it, please ask again. I'm waiting.

Grupo:


See as you just wasted explanation. The person you were explaining to would not even understand half of the things you wrote

he doesnt have to...have some respect....he or she may understand other things better than you....dont insult others because they dont understand somethings.....

I can't see any drainage channel for water to flow throough and avoid erosion, the soil in the east are erosion friendly and cement in concrete can be real slippery.

bantudra:

What do you think? There aren't any drainage channels in that picture and don't you think that combination can be real slippery when it rains??

for what do you need a drainage for a rural area...??...the enviroment is already drainage enough for the moment...when the area get more developed,then you can build a drainage beside the road...

slippery...??...i dont know about slippery....if your tires still have good grips then you dont have to worry about slippery....
even on aspalt your car will slipp with bad tires....

Offpoint:
In saner country it'll last that long, but in Nigeria I doubt... someone will purposely go there with a sledge hammer just to test it toughness.


Gush! I hate to be the last to comment, everyone will just drop their shíts on me.

You insulted him for asking a question while an engineer above answered the same question.

What does that tell us about you?

kaorama:

Close your mouth if you don't know what to say. Which one is friction and did they tell you the road was plastered or something? Why not google anything you dont understand before you make comment.

To the best of my knowledge, i know those soils in the east are liable to erosion , so i feel if there aren't any channels for water to flow off, it will eventually eat into the road but not to worry @okenwaa has cleared my doubts already..
