Attorney, Agent or FirmInternational ClassE01C 023/12AbstractA roadworking machine can be converted from front load road planing capability to cold in-place recycling capability by replacing the secondary conveyor on the front end of the machine with a mixer such as a standard pugmill. The machine can be converted in the field simply by detaching the conveyor from a-mounting assembly on the chassis and by attaching the pugmill to the same mounting assembly. The conveyor and pugmill are preferably attachable to the mounting assembly so as to be pivotable with respect to the chassis about both vertical and horizontal axes. The machine as thus constructed permits considerable versatility in both the discharge of milled materials from the secondary conveyor during front load planing and the discharge of recycled materials from the mixer during cold in-place recycling.Other References
