Excerpt: ...whether the resulting curve is a parabola, as will generally be found to be the case. When the vertical curve extends more than one station each side of the vertex, the following method is preferable, which is also applicable to the above case, and is in some respects preferable for that also. 136. Problem. Given the rates of grade gof AV; g' of VB; the number of stations n, on each side of vertex, covered by the vertical curve; also the elevation of the point A. Required the elevation, at each station, of the parabola AB. Draw vertical lines,"" DD'D," EE'E," VHL, YBM " Due regard must be given to the signs of g and g' in this formula, whether + or--. The labor involved is not materially greater in many cases, for a vertical curve than for a straight grade. This method has the additional advantage that a correct final result at the end of the vertical curve makes a "check" upon all intermediate results. 15 137.50 The elevation for Sta. 15 thus obtained agrees with the eleva. tion shown in the data. All the intermediate elevations are therefore "checked." 138. Problem. Given g, g', ai Required n From (86) n = 22.'

Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
