Accra-Tema motorway: Asphalt will reduce cost by 20%

The Ghana Chamber of Construction Industry (GCCI) is urging government to abandon plans to use concrete to construct roads including the expansion of the deteriorated  Accra-Tema motorway.

Asphalt hot mix overlay

Rather, government should use 200mm or 300mm asphalt hot mix overlay measuring 12 inches to reconstruct the Accra-Tema motorway to take care of heavy loads and high traffic.

15% -20% cost savings

According to the Chamber, using asphalt will reduce the cost of reconstructing of the Accra-Tema Motorway by between 15% and 20%.

Man hours to be saved

Chief Executive Officer (CEO) of Ghana Chamber of Construction Industry Emmanuel Cherry told The Finder that the financial savings to be made can be used to construct other roads not forgetting the man hours to be saved.

It is expensive to maintain concrete roads

He explained that the cost of maintaining asphalted roads is far cheaper compared to concrete roads

Concrete roads in the Tema enclave cracking

He cited some concrete roads in the Tema enclave which are cracking saying the weather in the country do not support building of concrete roads.

Curing of concrete roads take months

Cherry also pointed out that curing of concrete roads take long citing Accra-Tema Motorway which was completed in 1964 but opened to traffic in 1965 because the curing took about seven months.

Curing is the maintenance of a satisfactory moisture content and temperature in concrete for a period of time immediately following placing and finishing so that the desired properties may develop.

Concrete expensive than asphalt

Despite new technology to reduce long curing during, he believes it is not worth it coupled with concrete being expensive as compared to asphalt.

USA, Germany reverting to asphalt

Because of new technology, he stated that countries such as the United States of America, Germany among others now build roads with asphalt overlay instead of concrete.

Accra-Tema Motorway interchange

Though the Accra-Tema Motorway interchange contract was given to a foreign contractor, Cherry said 90% of the works were done by a  local contractor.

Flyover on the motorway

According to him, the flyover on the motorway to Flower Port on the Spintex Road was also given to a foreign contractor but a local contractor is doing a greater part of the work.

Impact of high lending rates

He cited high lending rates as a major killer making it difficult for local contractors to mobilise funding locally for projects.
