RSU Don Identifies Obstacles To Nigeria’s Road Construction Success
A professor of Highway Engineering at the Rivers State University (RSU), Prof. Emmanuel Osilemme Ekwulo, has identified poor designs, inadequate materials, insufficient testing, and lack of accountability as major obstacles to the success of highway construction projects in the country.
Ekwulo made this remark in Port Harcourt last Wednesday during the 128th inaugural lecture series of the university, where he presented a lecture titled “Removing Roadblocks: Rebuilding a Foundation for Reliable Highway Pavement Infrastructure.”
The university don lamented the consistent premature failures of road construction projects nationwide, despite huge investments by the government at all levels, attributing the problem to neglected basics and systemic principles in the industry.
According to him, rebuilding the foundation technically, institutionally, and ethically is crucial to building strong and lasting pavements.
Ekwulo emphasized the need for political will, professional integrity, and commitment to engineering excellence to overcome the challenges.
“The metaphoric roadblocks are those challenges causing premature failures,” Ekwulo said, adding that identifying and addressing these roadblocks is key to rebuilding the nation’s highways.
He recommended that institutions involved in road design and construction adopt a mechanistic-empirical design approach, and develop a comprehensive framework for implementing the Nigerian Imperial and Mechanistic Pavement Design System (NEMPADS) approach.
Ekwulo also advocated for mandatory traffic load analysis, strengthened university-industry collaboration, and funding for applied pavement research.
Corruption, he noted, is a major challenge in the profession, saying severe punitive measures are needed to curb shabby practices leading to premature road failures.
The Vice Chancellor of the university, Professor Isaac Zeb-Obipi, described Ekwulo’s lecture as interesting and intriguing, highlighting the importance of implementing solutions to Nigeria’s highway challenges.
The Vice Chancellor also described Ekwulo’s proposals as practical and applicable to government and industry stakeholders.
He said the university is committed to research aligned with national development goals, referencing its NDV-12 responsive consortium production framework.
Zeb-Obipi noted that Ekwulo’s recommendations are timely and solution-driven, and will contribute to addressing Nigeria’s highway challenges.
