1.Preliminary investigation from the picture reveals expansion as the major cause of the crack, the heat this year is intense, they was no (Joint) provision made for expansion.
2. The underneath soil is expansive clay, which swells due to the rainy season hence the result you are seeing.

Recommendation:
The concrete should be partitioned leaving room for slight Earth movement ( this will prevent crack as a result of expansion of reinforced concrete as a result of extreme temperature and Earth movement)

Is it cheap or costly to rectify?

Ashamed of himself how?
I think we are doing compare and contrast?
The guy showed us the dilapidated state of the roads and bridge your general Bitter Obi did when he was Governor, and you are saying is the guy not ashamed of himself.
Obedient always run away from fact...hypocrite set of people.

Nwaokunkpara:



Are you not ashamed of yourself

Umahi is nothing but an oluwole quack engineer with a penchant for stealing. That man is an embarrassment to the people of Southeast. What a loser!

Concrete roads don't last except if asphalted afterwards. Umahi built ridiculous ugly concrete riads in Ebonyi but the present Governor is trying to pave some of them. This one is Amasiri road

He's a well read Engineer but his problem is believing he knows it all and cannot be corrected. He went ahead using concrete to build Airport runway which made Airlines unable to use the Airport .

Below is one of the bridge constructed by Bitter Obi.

I am waiting for OP to call him out instead of getting fixated on Umahi who have more record of visible infrastructure he embarked on.

Nawaaoo for una, though I hate obi because he is not supporting biafra instead he is busy wasting his energy and resources on the Zoo; but for the past eight years now is obi holding any political office in the zoo,why always call him out someone that govern Anambra for a very long time; three or four governors had been there up till this thing . Una just dey one kin..

FatherOfJesus:
A lot of his concrete roads are failing.

David Umahi act as if he knows too much. This same man constructed concrete runway in Abakaliki airport that is not safe for planes to take-off or land on because of poor grip hence commercial airlines avoided the airport (aside that the airport has no economic value). He wasted 40billion.

While I know that concrete roads are good if they are properly constructed, like the one in gbagada, but Umahi will be forming engineer while he cannot deliver quality roads in his state.


I don't trust the quality of the concrete road that Will be delivered on the coastal road project. Umahi likes substandard and shiny things like China and Hitech construction company is not reputable enough to handle such magnitude of project. The only construction company I can trust to deliver is julius berger.

Why should he be ashamed of saying the truth?

Nevertheless, the road is still motorable with some slight discomfort.

Bad belle people want to throw the baby out with the bathwater

Imagine the poor quality ...abeg someone should send me roads done with concrete in Oga Fashola's time

The roads ogbemudia did in Warri since more than 40 years ago are still intact... This present politicians will not die well
Moreover those roads are not tar but concrete

Dijita:
I support the Lagos Calabar coastal highway. This is a legitimate concern. The press should ask the minister why Nigerians should trust him with such gigantic project when the one he did as governor is already cracking.

nigeria no get press na influencers we get and na only clout dem like

Aggregate strength is zero. No industrial water seal in it

Nice one. The rubbish weh dem tell una for dat whatsapp group to dey spread don finally reach nairaland. So in all d concrete roads in ebonyi na dis small tyn una fit lift as work not done well. I was expecting a big hole. U weh never go pass border, dey talk say China na Substandard, even usa no fit talk dat one.

The way that is not good to be praise singer,is also the same when you are perpetual wailer.


Criticize when they do bad and praise when they do good, but for many of you, you must attack for you to feel important. Perhaps, criticism reliving tensions from u guys.

Old news

ekineme:


The problem with some of you is that you are too insultive, can't you pass your message without insult?
For the sake of information:
Longitudinal crack in concrete pavement is caused by the presence of highly plastic clay( expansive) soils as the subgrade material and changes in the moisture content of these soils due to climatic changes.
Ensure you put yourself in order before quoting me Mr Man.

2. The rigid pavement Umahi constructed was reinforced with Y8 rod which is the primary cause of the thermal expansion due to extreme high temperature.

3. Ebonyi falls under the tropical monsoon region which has alternate high temperature and heavy rainfall, considering the underneath soil is plastic clay, what do you think will happen when the clay absorb water?

All of the above should have been put into consideration before construction started to ensure longevity.

Na so dey go do our coastal road

The spirit of APC is in him. It's finished!!

Beautifulday:


It's not about substandard. Concrete has low expansivity ratio. So will easily crack under high temperature or low temperature. For it to last, it must be overlayed with asphalt.

But the concrete Road that Dangote built in Lagos is Solid without asphalt

NwaNimo1:
Heat expansion not considered.....one of the benefits of tar is that it expands and contracts



Umahi is an illiterate responsible for so many atrocities and monstrosities!

Don't you see expansion and contraction joint in that pictures

This is not surprising...!

With the haste and paparazzi he used to carry out those projects, I just knew they would be substandard.

Same with his elder brother in corruption... Rochas Okorocha of Imo state.
