| Abstract: In paved roads, storm water drainage is vital. Poor drainage allows water to remain on road surface for longer time periods, which in turn will negative influences traffic safety and flow efficiency. Furthermore, it can increase the water in gress to pavement layers leading to a significantly rapid deterioration of pavement structure. In straight segments paved roads, pavement cross -slope is essential to drain surface water away from carriageway surface. International and local experiences pro vide typical values for road cross slope to be used for drainage consideration without considering the characteristics of pavement surface or carriageway width. This paper focuses on establishing practical design criteria and CAD simulation that can help in selecting the minimum accepted pavement cross -slope for drainage taking into consideration the effect of pavement surface conditions, road surface characteristics, and carriageway width. | ||
