Show stabilization of roads saves motorists money increased safety and lower costs both to the motorist and in highway maintenance are obtained through the stabilization of gravel roads says associate professor roy S swinton of the university of michigan department of engineering research in a survey of wear on several michigan highways professor swinton discovered that stabilization I 1 saved about two thirds of the material losses which are so great on loose untreated gravel roads stabilization consists of the use ol of proper mixtures of soil moisture and chemicals in road construction in professor swinton Swin tons s survey begun in 1935 extensive a and nd continued examinations were made of gravel roads in five michigan counties about wear readings were made on these five road sections while a saving of more than 60 per cent was made on stabilized roads professor swinton found other roads receiving surface treatment with calcium chloride had only about one half as much material loss as the untreated roads the cost of road stabilization says professor swinton is little or no greater than the maintenance cost of untreated roads where the loss of materials is so much greater in addition he points out the stabilized road is much safer because it is dustless and has no loose surface and at the same time allows greater speeds which may be c counted aunte d as a saving for the motorist |
