Normally ...it's won't make much economic sense to use cement on roads that don't experience very heavy traffic in term of usage ...such as streets and intra-city roads. But since Nigeria have completely jettisoned rail-transportation for our cargo haulage transportation...investing in such cement-based roads is not out of place. Presently....the whole of the access roads inside Tin-Can Apapa is cement based because of the heavy exposure to articulated trucks laden with containers and all sort of heavy cargoes....below is a road made of cement inside Tin-Can. Despite the heavy abuse suffered by that road in the last 8 yrs....not a crack...talk less of a small hole is on it. 1 Like

Ngwakwe: How will the dust oozing out from the road over time be managed considering high temperature and low humidity in our clime? If properly done, I dont see dust oozing out from the road. Alot of roads in the US are made out of cement and I dont see it oozing. my only concern is friction when the roads are wet or cold. The cold is less of a concern because of the weather in Nigeria. I think it is a good development and if properly done will last longer. |

manny4life: I am relaxed, I am not prone to losing my cool over issues with faceless bots on the internet, not in a 100 years. I am not proud, just assertive. I know what I know. But I am not gonna take this literally, coz this is not about me. The issue is I do not think it smart that non domain experts discuss expert knowledge that ONLY domain experts can intelligently discuss without arriving at wrong conclusions. non experts do not even ask the right questions, since there premise is not backed by any technical training or experience in the domain to which the pretend to debate. This usually results in misinformation and the propagation of half baked ''expert'' opinions. You cannot find me discussing the merits and demerits of surgical techniques for complex proximal tibial fractures, that can only be discussed by the domain experts, that is the surgeons practicing in that field, you may trust their conclusions, or not, but it is silly for a Civil engineer to start debating or discussing that. Civil Engineering Design practices and construction is not forex or stock trading, that you can learn and understand practically without a proper technical training in it in a week. Leave the domain topic to the domain experts, then you will not have a layman arguing with the Engineer on a project just because he got some misinformation from a forum on the internet. 2 Likes |

This method of road construction may solve the road infrastructural gap in Nigeria! Good development.was wondering when Nigeria will catch up with these worldwide trend. |

alpontif: Oya, you're relaxed right? Ok we've heard you, this is why you don't see me in topics concerning engineering. We who did not study engineering like to ask dumb questions, but there's nothing wrong in answering either. Ok... Sorry o if anyone pinched your skin, ok PLEASE explain more on the issue to the NL community, we'd love to hear it, half baked or full baked, or even expert and advanced baked, it doesn't matter. 1 Like |

From an engineering and soil aspect. The concrete road is better than the asphalt road. The concrete road has a life span of 40years unlike the asphalt road whose life span is 10years, so no need for immediate maintenance. Concrete roads are not pollutants and they help save our ozone layer unlike asphalt, when melting the bitumen, it releases awful smell. Concrete roads help to save fuel because of its low traction force, unlike asphalt roads, it has high traction/frictional force. So we lose more fuel using asphalt roads dan concrete roads. Moreso, with the high frictional force, it tends to release more carbonmonoxide to the atmosphere, thereby polluting the environment. Concrete roads are durable during high rainfall, but asphalt roads get weak during high rainfall. During oil spillage, the asphalt is dissolved by the organic content of the petroleum oil. But cements will not dissolve in it. The only problem of the concrete road is that it takes time and more money. It also has very low friction during the raining season, more cars on high speed have high tendency of skidding. We can solve the problem of low friction by making the surface alittle bit rough with some gravels, cement and tar. 4 Likes |

^^nice very informative. so do you think this method will be good for nigeria? |
Re: Nigeria Begins Use Of Cement For Road Construction Against Asphalt. by knightsamsong(m): 3:58pm On Oct 11, 2013 |
chemically, cement which is limestone caco3 is less stable dan asphalt, especially when it reacts with rainfall and excess sunshine...it dissolves away...nigerian roads which are barely maintained, cement based road will b a disaster! |

alpontif: It is simply irresponsible and absurd for you to make a point which expresses your reservations to an idea being put forward, while not providing reasons why your submission should be respected. By performing an act of autolatry and being a pessimist would do a disservice to the ideology behind your position on the said topic. Being an autohagiographer and not educating the minds of your fellow forumites, is not justifiable because by going through @eledan's submissions, there was no place where your level of intelligence was questioned and he even apologized when its not wrong for him to ask questions. Your choice of words portrays you as an aeolist, which doesn't speak well of your professionalism and courtesy demands that you apologize for the un-needless outbursts and temper tantrums that you've been throwing on this thread. The essence of humanity is to cohabit and help each other's deficiencies hence the hunting in packs by the early man. While its within your rights as an individual to have a different opinion, its unacceptable for you to insult the person asking questions out of curiosity 6 Likes |

If it is cheaper and takes less expertise to construct,then lets have it. It is a good improvement that the constant lie of "we are waiting for asphalt" we hear everyday from our governors. |

Nate7even: Well cement is good for compression so it handles heavy duty trucks well, but if not properly mixed and cured in our type of climate it will crack and the cracks will be quite long, also cement will creep(flatten) over time but another layer can be laidYou failed to mention that corruption will creep in through infiltration of adulterated cement. They will begin to mass produce adulterated cement, just like buildings are collapsing ,so will roads constructed with adulterated cement, better watch out, if that's the case, Nigerian roads could be very very dangerous. |

alpontif: Dude...you need to GTFOH !! if you dont have any meaningful contributions on the topic !! NL is not Civil Engineering Journal where we are all experts...if you have an expert opinion,then render it instead of clambering on your high horse..The fact is that as a lot of people have expressed a great deal of roads in the western world are constructed using concrete. I personally believe that in terms of cost, ashphalt/bitumen is better for Nigeria as we have them naturally occurring in great abundance...but again we await for supreme expertise on the subject O Great Professor!! 1 Like |

Ngwakwe: How will the dust oozing out from the road over time be managed considering high temperature and low humidity in our clime?Cement serve as the base, moreorless the foundation before is alphaft lay. Even if the road is completely concrete, its no problem for vehicle. Its smooth and safe. |

Ngwakwe: How will the dust oozing out from the road over time be managed considering high temperature and low humidity in our clime? Tried and failed method is now in vogue in the jungle called Nigeria. Without steel reinforcement, the roads build only with concrete will not stand the test of high temperature, humidity and stress in Nigeria. |
Re: Nigeria Begins Use Of Cement For Road Construction Against Asphalt. by DerideGull(m): 6:03pm On Oct 11, 2013 |
What you see on the USA roads are not mere concrete as Nigerians tend to think. In USA, steel reinforcement is applied including chemicals that allow the concrete to withstand tensional force. |

i think its a good idea considering how brigdes are built first with reinforced concrete and its then covered with tar.( e.g. Oshodi-Apapa expressway bridges are more in good shape than the road itself which both has been constructed 2 decades b4 many roads built in the last 13yrs of our jovial democracy) |
