The small stones quickly crush up, and the surface of the roads becomes uneven and muddy. It is very doubtful if in a term of years a gravel road will not cost as much as a macadam road, and it can never be as enduring ; the wearing surface receives the shock of all traffic ; the materials for its construction must be carefully selected....

Seite 81 - Saugus have been in continuous use for twelve years, with no repairs, and are yet in good condition. In but few cases can our gravel be economically used on the main roads, over which there is much travel. Nearly all gravel banks now in use contain more or less stone from the size of an egg upward, with quite a large percentage exceeding two and one-half inches in diameter. No stones larger than two and one-half inches through should be used within four inches of the surface in the construction of...
