ABSTRACT:
Method and apparatus for maintaining a road or the like wherein liquid asphalt cement and aggregate are separately carried to a job site. The temperature of both of these is maintained within a range of from about 70.degree. F. to about 250.degree. F. for the aggregate and a range of from about 100.degree. F. to about 195.degree. F. for the liquid asphalt cement. The aggregate is metered onto delivery means and delivered thereby to a mixing means. The liquid asphalt cement is pumped from its container to the mixing means whereupon the aggregate and the liquid asphalt cement are mixed together and delivered to a spreading means. In addition, a filler hopper and metering means for filler material can be provided as well as a second tank for water with associated metering and piping means can be used. Two specific embodiments of the mixing means are presented, namely, a homogenizing mixer and a mix-conveyor. Auxiliary power means are provided for powering the moving elements of the apparatus. Infrared heating means can be used to heat the aggregate and/or filler material prior to their entry into the mixing means. The entire apparatus is mounted on a mobile frame, such as a truck.
