Application of Cost-Effectiveness and Durability of Cement Treated Base in Road Construction

Abstract

Cement Treated Base (CTB) is a type of stabilized base layer widely used in modern road construction to improve pavement strength and durability. It involves mixing a predetermined amount of cement with aggregate and water, resulting in a bound layer with enhanced load-bearing capacity and resistance to environmental conditions. The expense of producing the base layer of road and material used in pavements, including as drilling, blasting, crushing, and transporting, makes it an expensive choice. However, when subjected to high traffic and/or strong weather, this material does not hold up. The purpose of the research is, to increase the load bearing capacity of the road using CTB at feasible cost. The methods used are the Unconfined compressive strength, Modified proctor test for the cement-treated base. Results showed the optimal strength at the 3.5 % cement ratio, indicating its suitability for high-load-bearing applications. While 4% cement ratio demonstrated the least amount of rutting, making it ideal for high-traffic roads and areas prone to heavy loads. Cracking behaviors was influenced by both the cement content and curing conditions. The CTB methods saved the most money on construction costs of road, focusing on its benefits and inconveniences. In light of the writing survey and contextual investigations, the paper reveals that CTB can be a practical and robust solution for roads, development, especially in regions with frail subgrades or high traffic volumes.
