Gravel roads and broken stone roads are similar in many re-spects, but when broken stone is used the foundation is usuallyconstructed more scientifically, and the road then assumes the nameof a macadam or telford road. There are different methods used in the construction ofgravel roads, but the principal is the same. Gravel is spread ona well drained earth road, tc a depth of from four to eight inches,and leveled off so that it assumes the general cross section ofthe road. The surface is then either rolled with a steam roller,or left to be compacted by traffic. In this manner the surfacestones are forced intc contact, and become more or less firmlycerented together, forming an impervious road, surface.
