Abstract

This paper examines the use of earth materials in sustainable road
construction in South East, Nigeria. The study aims to determine factors
associated with the use of earth materials, identify limiting factors, and
examine strategies to improve their use. The study population comprised 60
engineers and craftsmen using local materials. The results show limitations in
the use of earth materials in sustainable road works. The study recommends
contracting firms to develop better storage facilities for earth materials to
prevent damage and wastage. It also suggests incorporating earth materials
into construction education curriculums to sensitize students to their potential
benefits. The government should adopt a policy of adapting earth materials
that require minimal capital and foreign exchange and utilizing available raw
materials and skills in small-scale operations. The study's findings highlight
the importance of sustainable road construction in Nigeria's socio-economic
growth.
