            Abstract:
            That the American public is expecting mor and more of its roads and pavements is indicated by greater use of highways, demand for better types of construction, and the mileage being built that could not have been concieved a few years past.  Pavements considered highly satisfactory a few years ago are generally condemned today.  Nearly every one has become so exacting of quality that a mere visual blemish is the object of criticism.
