The Minister of Works, Engr. David Umahi has stated that the federal government has decided to prioritize rigid concrete pavement over traditional asphalt overlay in constructing federal roads across the country.
Umahi highlighted several reasons behind the strategic shift, with durability and cost-effectiveness at the forefront.
He explained that concrete technology offers a more resilient and cost-efficient solution compared to asphalt, which has faced challenges related to cost escalation.
During a press briefing in Port Harcourt, the minister pointed out bureaucratic bottlenecks as a significant factor hindering the efficient execution of construction contracts.
Umahi stated, “When we came on board, we foresaw that the cost of asphalt would continue to increase. Besides, the bureaucratic processes involved in obtaining approvals for projects with costs exceeding N1.5 billion were causing delays.”
He elaborated on the complications arising from the need for projects to undergo evaluation by the Bureau of Public Procurement (BPP) and subsequent review by the Federal Executive Council (FEC).
Umahi emphasized the burden of dealing with numerous projects, each requiring evaluation and approval, especially when faced with the dynamic nature of contracts.
The minister further highlighted the instability and excessive cost of asphalt in the market, which has been influenced by fluctuations in forex exchange rates and the rising oil prices globally.
“The progression of asphalt costs is geometric and exponential, whereas that of concrete is arithmetic. Concrete road construction offers a more stable and sustainable solution,” he added.
Umahi also proposed the development of bitumen deposits in Ogun and Ondo states to mitigate the challenges posed by the rising cost of bitumen, a key component in asphalt production.
He also suggested a hybrid approach, incorporating a two-inch asphalt overlay on concrete roads to address concerns about asphalt failures over time.
According to Umahi, concrete roads are designed to withstand the test of time, with a lifespan of up to 50 years, providing a durable and long-lasting infrastructure solution.
