MIX DESIGN OF CEMENT CONCRETE PAVEMENT

Cement concrete pavement has become increasingly significant in contemporary highway engineering owing to its superior durability, high load-bearing capacity, and extended service life. The performance and longevity of rigid pavements are strongly dependent on the quality of the concrete mix design. This study provides a detailed investigation of cement concrete pavement mix design, with particular emphasis on the selection of materials, proportioning techniques, strength parameters, and workability requirements. The research adopts internationally recognized mix design methodologies and examines the correlation between mix proportions and pavement performance. The findings indicate that properly optimized mix designs lead to substantial improvements in compressive strength, flexural strength, and durability, thereby enhancing the suitability of cement concrete pavements for roads subjected to heavy traffic loads. The paper concludes by offering practical guidelines for pavement engineers engaged in the design and construction of rigid pavements.
