Excerpt from Earth, Sand-Clay, and Gravel Roads In general, the fig. 7. - Use of wooden breakers to prevent scourolorfreside2 amount Of crown dith should be greater on grades than on level stretches Of road, because the tendency for water to wash away the surface by collecting in and flowing along ruts depends largely upon the steepness of the grade. Also the care with which a road is to be maintained may have an important influence on the amount Of crown that should be given to the surface. It is evident that'a road surface maintained in a smooth uniform condition will shed water off to the side ditches with much less crown than would be required where ruts are allowed to form.
