Tie roadway is to be constructed so that there is one regular gradient between points A and B. (a) Draw a longitudinal section along the centre line at a horizontal scale of 1:1000 and a vertical scale of 1:100. (b) Determine from the section the depth of cutting or height of fill required at each chainage point to form a new roadway. (c) Check the answers by calculation.
