Ice aggregate road and method and apparatus for constructing same

摘要

An ice aggregate road structure and apparatus for constructing. The road structure comprises crushed ice aggregate from which fines smaller than 0.1 inch have been removed which aggregate is placed in the desired shape and then bonded by a deeply penetrating application of water which bonds aggregate particles at their points of contact. The apparatus includes a distribution box for receiving ice aggregate and distributing it over a road section to be paved coupled with a bond water distributing means for quickly applying bond water after proper distribution and shaping of the aggregate. The distribution and water spray elements are carried on rails which are in turn supported from a pair of spaced apart carriages containing water heating and pumping means and appropriate power sources for operating the equipment. The carriages are spaced apart to allow trucks to deliver aggregate. The distributing means support elements may be inclined to increase the elevation of road surface or to generate bank in the road. The entire apparatus is designed to move forward over each section of road immediately after construction so that the road structure may be produced without disturbing the underlying earth surface.
