Comprehensive Analysis of Roller-Compacted Concrete for Road Infrastructure: Materials, Performance, and Applications in the Sub-Saharan Context

Road infrastructure is crucial for economic and social development, especially in Sub-Saharan Africa, where it ensures connectivity and mobility. However, bitumous pavement deterioration is common due to harsh climates and inadequate adaptation of materials and techniques. This highlights the need for innovative and durable solutions. Roller-Compacted Concrete (RCC), a no-slump concrete compacted with vibratory rollers, offers a promising alternative. Known for its strength, durability, and cost-efficiency, RCC has seen growing global interest but remains underutilized in Burkina Faso and other regions. This paper presents a comprehensive analysis of the use of RCC in pavement applications. It examines constituent materials, mix design approaches, and mechanical and durability performance under various environmental conditions. Recent advancements and practical applications are also discussed. The study identifies research gaps and concludes with recommendations to support the adoption of RCC technology in Sub-Saharan Africa’s road construction sector.
