According to De-Graft Afful, the money involved in reconstructing new roads is so huge that government has to always resort to the routine pothole patches to keep the roads motorable.
The cost of patching these potholes, he admitted was less as compared to the several millions used in building new roads.
“The money involved is so huge when we want to reconstruct. So for the time being; we try to patch so that the public will have a comfortable ride as we plan for resources to reconstruct these roads or apply asphalt overlay or reseal them,” he said.
According to him, after the roads have outlived their life span, they ought to be rehabilitated to give road users smooth access.
Explaining further that, a typical surface dressed road is supposed to last for seven years while an asphalted road has a life span of between 10 to 15 years depending on the thickness of the asphalt.
However, due to financial constraints, he pointed out “we’ve not been able to do anything on them” and therefore, have sought to patching them.
He indicated “if we don’t do these stop-gap measures, the roads are going to totally collapse and you will ride on big; big potholes and you’ll start complaining again.”
Asked if the huge sums of money used in patching existing roads could not be channeled into the construction of new roads, Mr. Afful responded it is better “to keep your old asset in very good order before you add on”.
“But here, everybody is crying for a new road and the temptation is that, we go out there trying to meet that need and then the old roads are all left behind, hence the problem we are going through.”
He emphasized that “we need to preserve the investment and then we will carry on with other more investments that we want to undertake.”
Bylaws to protect roads
Touching on laws governing road users, Mr. Afful indicated that the Urban Roads itself did not have any laws and so, it is the Assemblies’ responsibility to ensure that the roads were protected, mentioning that they have enough by laws to do this.
The public, he added has the responsibility to also ensure that “the roads that have been built in our areas; nobody will misuse it. If we do that, the roads will last for a very long time. But it’s like nobody cares.”
He also noted that through the Road Fund, public fora were held periodically in all the regions to educate people on how to preserve the roads to last long.

President-elect of the Ghana Institution of Engineers, Kwaku Boampong also spoke to Myjoyonline.com, saying, the patching of potholes on the roads was part of minor routine activities done to preserve the roads from further deterioration.
“But in our system, because we do not have the money to do it, sometimes we are not able to follow the maintenance schedule for the roads. So we try to use what we have,” he said.
Long lasting and durable roads, according to him, depended on a lot of things including the number and classes of vehicles, which would be plying the road.
“In the design, you will pick previous information that is available and then you project into the future. If you want the road to last for may be, ten years; then you project into the future.”
And for those ten years, there should be some periodic maintenance action by strengthening the pavements to some levels, he added.

A visit by Myjoyonline.com to the Ledzokuku-Krowor Municipality saw patching works being carried out on affected portions of the roads.
Municipal Roads Engineer at LEKMA, Domingo da Pilma Lekettey observed that the cost of patching potholes could not build new roads since huge sums of money were required.
He said typically, about GH¢40, 000, depending on the work to be done, could be used on road patches in a month, noting that every square meter of potholes patched cost GH¢31 and the larger the potholes, the higher the cost.
He said currently, all ongoing works in the locality are premix patching, explaining, it is “a mixture of quarry dust, ten millimeter of chippings, mixed with bitumen.”
