| Along with rapid development of HeiLongJiang communication construction,traffic increase year after year,but the number of traffic accident is also show ascending trend.According to accident analysis result,estimation mistake or identifying lag,and vehicle high speed slippage that caused accident possess great proportion.Therefore,adopt proper technical measure to reduce number of traffic accident have important signification.Incremental frication and colorized folium on pavement possess function such as offering clear vision caution,leading vehicle,prevent slip and speed-down,it is an efficiency technical measure that improve pavement security.Because of importing this technique later,correlative research pinch,incremental frication folium stonematerial and felt-material don't have technique standard,construction craft and pavement project nonstandard,applicability in cold zone,these problem need to be resolved.We investigated and concluded technical index of incremental frication folium stone-material and felt-material,on the base of experiment,recommended proper technical index of cold zone.According to the analysis of incremental frication and colorized folium practical performance,bring forward experiment estimation method such as felt intension,shear intension,avulsion intension,fatigue performance and stone-material polish value etc,integrate climate character of HeiLongJiang province,considered influence of freeze-thaw and salt(use to clear snow) firstly.Bring forward that utilize mentality effect of color and notice to cooperate with the other security establishment when designing pavement project,sort of section that have high accident ratio,from different section, bring forward relevant pavement project and assistant measure.Integrate construction of experiment road,concluded construction craft,according to systemic observation and performance investigation, verified applied feasibility of incremental frication and colorized folium in cold zone. |
