What practical application is associated with knowing the drainage coefficients in pavement design?

• A. Moisture control
• B. Load distribution
• C. Temperature management
• D. Thickness design

Answer: (A)

Knowing the drainage coefficients in pavement design is crucial for effective moisture control. The drainage coefficient indicates how well a specific material can manage water infiltration and the subsequent flow. Adequate drainage helps keep the pavement structure dry, preventing the accumulation of water that could weaken the pavement layers and lead to premature failure. This understanding is particularly important in designing pavements to ensure they can handle rainfall and other water sources without compromising structural integrity or safety. While load distribution, temperature management, and thickness design are important factors in pavement engineering, they are influenced by other parameters more directly tied to structural capacity and material properties rather than the immediate concern of moisture control, which the drainage coefficient directly addresses. Therefore, the focus on drainage coefficients highlights the importance of maintaining an effective drainage system, thereby extending the lifespan of the pavement and enhancing its performance under various environmental conditions.
