Ane.from Table 30.6. For same slopes but other widths <br /> of roadbed,correct above figures by one-half difference in width of roadbed;thus in <br /> tea; example above,for 20 ft.roadbed distance will be 30.6-1-(20-16)+2 or 2 ft.added to <br /> 80.6=32.6. For slopes of 1 on 1,q see inside of back cover. <br /> Copyright,1914,by Eugene Dietngen Co. <br /> I <br /> t <br />. , dV <br /> S ' <br /> t <br />
