Super elevated roadway
WebMar 22, 2024 · Super elevation is provided to achieve the higher speed of vehicles. It increases the stability of fast-moving vehicles when they pass through a horizontal curve, and it also decreases the stresses on the foundation. In the absence of super elevation on the road along curves, potholes are likely to occur at the outer edge of the road. WebWhere a crown section is used for rapid drainage, the shoulder slope must be steeper than that of the pavement (See the chart above), but on a pavement uniformly sloped either to the outside or the inside (such as on a super-elevated curve), the shoulder slope generally is the same as that of the pavement.
