During the last week o£ September, 1956, the Division of Rural Highways requested assistance from the Research Division in conducting a series of ten experimental base stabilization projects which were to be geared more-or-less to a practical rural roads development program in which existing soils and local granular materials might be most advantageously treated and stabilized to provide fairly low cost base courses and surfaces, adequate for light rural traffic. The idea of actually constructing a base and bituminous surface for this type of road would represent a refinement over the traditional traffic-bound base type of construction which usually serves as a preliminary to light bituminous surfacing. While the traffic-bound type of construction has been used effectively in the past, there seems to be an inherent impatience on the part of property owners and general public to get on to the bituminous surfacing stage before the traffic-bound base has fully stabilized. In several such instances it has been necessary to add extra surfacing within a year or so, or else to revert to the traffic-bound stage again and start over.
