In　order　to　explore　the　mechanism　of　low　temperature　construction　and　influence　of　additives　on　the　high　temperature　performance　of　the　asphalt　concrete　pavement,　the　viscosity　at　110C,　120C　and　135C　and　softening　point　were　measured　for　SBS　modified　asphalt　and　base　asphalt　with　different　additive　content　of　ADZ,　ADW　or　ADS,　respectively.　The　additives　can　reduce　viscosity　of　asphalt　and　realize　construction　of　asphalt　concrete　in　low　temperature.　The　experimental　results　showed　that:　To　some　extent,　three　kinds　of　additives　can　reduce　the　viscosity　of　base　asphalt　or　SBS　modified　bitumen.　In　contrast,　at　lower　temperature　(120C　or　110C),　the　viscosity　of　SBS　modified　asphalt　and　base　asphalt　with　ADW　or　ADS　were　obvious　smaller　than　that　of　ADZ.　With　the　increase　of　the　three　types　of　additive　content,　the　softening　points　of　base　asphalt　also　increased.　However,　the　softening　points　of　SBS　modified　asphalt　with　lower　additive　content　of　ADZ,　ADW　or　ADS　were　smaller　than　those　without　ADZ,　ADW　or　ADS.
