99thEnemy: So tell me why The roads done by JB in Lagos in 2001, which I assume are asphalt are still superb Awolowo road, Ikoyi Kudirat Abiola, Oregon Broad str, Marina Inner Marina Tejuosho rd, Yaba 1 Like |

The only downside to Concrete surface is the noise. Way too noisy than Asphalt. |

COMPAQ: Where you expecting them to spoil? it is known that standards concrete roads have a higher longevity to Asphalt roads. If you have a standard asphalt road with a certain longevity, expect a standard concrete road to last longer. donโt forget the mention of the term โstandardโ |

Asphalt is far better than concrete in terms of sustainability. |

Bunnatex:That is exactly how its done in high load bearing freeways in Indiana USA...........but you need experienced engineers to effectively accomplish such projects! If you use quacks ....you will regret ever going that route! This is the disaster that ruined the ebonyi airport runway! 1 Like |

The concrete roads they constructed in Yenagoa are all rubbish. They do not last more than a year before they scatter and look like the way it was |

Re: Concrete Vs Asphalt Roads: Which Is Better? by stanisbaratheon: 6:42pm On Mar 31 |
Depends of some factors. Cost, ease of maintenance, durability under traffic loads, ease of construction. 1. If you live where it rains every time then RC road is better. 2. If you live in a salty region (Southern region of Nigeria with high salinity), RC roads are also better because salty moisture could degrade bitumen easily than concrete. 3. Northern states with little rain fall throughout the year compared to the south can do better with Bituminous roads. 4. Overall, in terms of longevity, and long term cost, reinforced concrete roads are better. |

prophetfire: In Civil Engineering, what everyone knows as concrete road is actually rigid pavement. Flexible pavement is road done with asphalt. 1 Like |

Asphalt is cost effective Asphalt doesn't take much time, once it done, the road is motorable in 24hrs or less It tends to have a longer span when standard material are been used. Concrete isn't cost friendly It requires a long time to come into completion It tends to have a longer span on all weather conditions provided standard material are used |

Eleporobi: I was in Ebonyi state on Tuesday and Wednesday and those concrete roads done within the last 5 years had already begun to go bad . |
Re: Concrete Vs Asphalt Roads: Which Is Better? by SoloCraft306: 8:51pm On Mar 31 |
It's the Rigid Pavement for me because it could withstand appreciable amount of Axial load and could still withstand the atmospheric conditions of any sort unlike the Flexible Pavement that lacks those merits to some extents still it depends on the cost implications as to what,where and how the project needed to be carried out and who is awarding the project to who. That is why you would see some company will never collect a flexible contract job just because of the demerits I just spoke of. |

COMPAQ: Hmmmmm......the differential might not be as important as the highest temperature reached in the day. I know I talked more about the differential, though. |

flokii:That's really where the challenges lies, lack of professionalism by the contractor/consultant. Asphalt roads in Nigeria have been disliked due to the shoddy efforts of the building process. |

kenny714433: We are allowed to take differing positions on a subject matter even when we possess good information about it. Rigid pavements have a lot of advantages, but they are not a good replacement of flexible pavements where flexible pavements will do just fine. You know, we consider many factors when choosing a type of infrastructure over another. Cost, speed of construction, environmental considerations, etc. I like to tell people, the reason we in Nigeria feel that rigid pavements are totally better and should 100% replace flexible ones is because of corruption, which leads to substandard infrastructure. If an asphalt road is well built and properly drained, it will last and last. There are roads in Abuja built in the 80s by Julius Berger that are still in use, with maybe a little patching in about 40 years. There are also concrete roads that are rutted and cracked even though they were built less than 10 years ago. However, if we were to be honest, we will only consider rigid parents under special conditions where they are the absolute better choice. Thanks for respecting my position. I respect yours, as well. |

Eleporobi: Lie, you know nothing about road construction. Concrete is better and cheaper to maintain. I'm a Dangote staff tho and we've built over 2000km concrete roads in Nigeria. Our loaded trucks of cement weighing 45tons performed better on concrete roads than on Asphalt. Any repairs can be made easily by cutting out the bad portion with a precision engineered cutter and replace with concrete mixture. No compression vehicle, no oils, no rakes, no spades nothing- just some well mixed gravels and a skillful Workman. 1 Like 1 Share |

Concrete without asphalt is useless but concrete with asphalt is the best |
Re: Concrete Vs Asphalt Roads: Which Is Better? by VIKTO83(m): 3:14am On Apr 01 |
All your analysis is it based on 12000 naira/bad of cement or on 3000/bag cement? If our government should have to switch to Concrete basement, I suggest they set up a government owned cement factory which will ensure they use their stipulated quality. |
