What are the key considerations when designing and implementing pavement drainage systems?

Designing and implementing effective pavement drainage systems requires careful consideration of several factors to prevent water damage and ensure long-term pavement performance. Surface drainage is a primary consideration. The pavement surface should be sloped to allow water to drain quickly and efficiently. Cross slopes, longitudinal slopes, and shoulder slopes should be designed to minimize ponding and prevent water from accumulating on the pavement. Subsurface drainage is equally important. Subsurface drainage systems are designed to remove water that infiltrates the pavement structure or rises from the....
