The　modified　asphalt　coiled　material　is　widely　used　as　waterproofs　in　the　construction　of　highway,　railway　and　other　engineering.　The　asphalt　is　usually　paved　by　manual　work.　The　quality　of　paving　is　easily　affected　by　conditions　such　as　the　weather　and　the　worker＇s　skill.　However　the　working　condition　is　very　bad　for　the　paving　worker.　It　is　necessary　to　research　a　paving　machine　in　order　to　improve　the　paving　quality　and　working　conditions.　A　new　paving　machine　for　the　modified　asphalt　coiled　material　is　designed　in　this　paper.　Some　anti-interference　measures　were　adopted　in　order　to　adapt　the　bad　environments.　For　example,　PLC　is　used　as　the　controller,　AC　servo　motor　and　stepping　motor　is　used　as　executive　component.　Photoelectrical　coupling　is　used　in　circuit　connection.　This　new　paving　machine　two　controls　modes.　One　is　manual　control　mode.　The　other　is　automatic　mode.　The　worker　controls　the　paving　machine　through　operate　the　control　panel　in　manual　mode.　The　PLC　control　the　direction　and　speed　of　the　machine　in　the　automatic　mode　with　the　photosensor　seek　the　position　of　ground　markers　and　send　the　signal　to　PLC.　The　proportional　controlling　means　and　the　backlash　compensation　were　adopted　in　this　paper　in　order　to　achieve　accuracy　control.　After　numerous　experiments,　the　paving　machine　can　adapt　to　the　construction　requirements.　©　2011　IEEE.
