Book Description
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.

Book Description
Excerpt from Gravel Roads, Vol. 2: July, 1913 A well graded and well drained earth road is necessary for the foundation of any kind of an improved road; therefore, money expended on such work is not lost even though it be several years before the road receives a hard surface. In building any good road, the first essentials are a careful survey and suitable plans. As most of the Michigan roads that will be graveled are old roads now in use, and which have been in use for many years, there is but little opportunity to make new locations. However, when new locations are made, as they still are in the newer and sparsely settled counties, the work should be done with the same regard for easy grades, low cost of construction and fitness of roadbed as would characterize a railroad survey. Due prominence should be given to directness, but it should be remembered that the primary object of section lines is not to define the center lines of highways, that the distance around a hill may not be much greater than the distance over it, and that slight curves increase the length of a road but little. Sometimes the cost of a new right of way around a bad hill would not be so much as the cost of cutting the hill down to a reasonable grade. What has been said about new surveys applies with equal force to resurveys, except that old roads can seldom be changed unless the reasons for so doing are very strong. Permanent buildings, improved grounds, beautiful shade trees and other improvements become fixtures along old roads that make changes a hardship to the owners, who frequently, and often justly, strenuously oppose any suggestion of a new location. Nevertheless changes should be made where little damage would result, to avoid bad hills, bad swamps, sinking bogs, expensive stream crossings and sometimes to shorten the road. On old roads it is best to set the stakes along the sides, one row on each side parallel to the center line, and preferably 20 or 25 feet therefrom, so as to place them on the outer margin of the ditches or gutters where they will not be destroyed by ordinary traffic, nor so easily by grading teams. The plans should show: (a) the center cuts and fills; (b) the depth of each ditch or gutter from the hub stake adjacent thereto and (c) the vertical distance, up or down, from each side stake to the established center grade. Nothing less complete is satisfactory, for, in most cases, the work of grading is placed in charge of a highway commissioner or his foreman without the assistance of an engineer. Grades. In some parts of the State the most troublesome question to consider is that of grades. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Construction and Care of Earth Roads Roads should have plenty of light and air. Of course a shady road is very nice on a hot day; but such a road can not be kept in good condition, since shade is nearly sure to breed mud holes. Therefore the road Officials should use all possible diplomacy to have trees adjoining the road, particularly those on the south side, trimmed with reference to the benefits of the roads. A tall hedge cuts off the view of the adjacent country, shuts out the breeze, and in a dry time keeps in the dust and in a wet time retards the drying of the road. Therefore the road Officials should enforce the law concerning cutting of hedges. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
