About this document
Vertical Alignment and Curve Design by Nondumiso Ndlovu is a document available to read on EtoBox.
This document discusses the design of vertical curves for roads. It describes how vertical curves provide a smooth transition between intersecting gradients and allow for uniform changes in centrifugal force. It discusses the shapes of crest and sag vertical curves and how they are modeled using a parabolic equation. The document also provides an example problem calculating elevations along a vertical curve and discusses design criteria for determining curve length based on rate of gradient change, sight di
