The Modern Asphalt Pavement 1st Ed PDF Download

Excerpt from The Modern Asphalt Pavement The Subsoil Base - As the foundation of a pavement, of any kind, is placed upon the soil and supported by the latter, it is a matter of vital importance that this latter support should be adequate, and it will only prove adequate if the subsoil is not subject to displacement from settlement or frost and is thoroughly drained. With sandy soils which are well compacted and which, from their nature, are well drained and dry there is no difficulty in the preparation of a satisfactory subgrade. Trenches in such soils, if they occur, can be solidly refilled with the aid of water. If the subgrade is a true sand, as in the neighborhood of seabeaches, it may be necessary, in order to compact the surface, to spread a course of gravel between the sand and the base in order to be able to roll it properly.
