The　modified　asphalt　coil　is　widely　used　as　the　waterproof　material　in　elevated　railroad,　high　way　etc.　However,　most　of　the　asphalt　is　paving　by　manual　work.　An　automatic　and　wireless　controlling　machine　for　the　paving　modified　asphalt　coiled　is　designed　and　studied　according　to　the　need　of　improving　the　efficiency　and　paving　quality.　This　paper　introduced　the　system　design　of　the　mechanism　and　the　intelligent　control　of　the　paving　machine.　The　paving　machine　is　mainly　controlled　with　MCU,　PLC　(programmable　logic　controller)　and　CAN　(control　area　network)　bus　to　realize,　via　obtaining　signals　from　multi-sensors.　Meanwhile,　hardware　and　software　of　CAN　bus　and　have　been　designed　and　studied.　Two　working　mode　can　be　selected,　one　is　the　automatic　paving　mode,　the　other　is　the　steer　state.　The　scene＇s　experiments　shows　that　automatic　paving　machine　can　satisfy　the　need　of　paving　process.　And　the　automatic　paving　machine　greatly　improves　the　efficiency　of　the　waterproofing　paving　in　elevated　railroad　and　high　way.　©　2010　IEEE.
