【摘要】：采用光纖式結(jié)冰傳感器,利用凝冰實驗室和高低溫試驗箱模擬路面結(jié)冰環(huán)境,測得了不同降水溫度和路面溫度條件下的路面結(jié)冰厚度和結(jié)冰完成時間以探測瀝青路面的結(jié)冰過程。試驗研究表明:采用光纖式結(jié)冰傳感器測得電壓-時間曲線主要分為2種類型,與結(jié)冰的厚度有關(guān);路面結(jié)冰完成時間整體上隨著路面溫度的降低而減少,2℃以下的雨水溫度在約-2℃的路面溫度情況下,形成1 mm冰所需要的時間基本不超過10 min,能覆蓋瀝青路面的構(gòu)造深度;結(jié)冰完成時間整體上隨雨水溫度增大而上升,4℃雨水在路面溫度處于-1~-3℃條件下,形成6 mm以下冰的時間不會超過30 min。
[Abstract]:Using fiber-optic ice sensor, the ice-setting environment was simulated by using ice coagulation laboratory and test box of high and low temperature.The ice thickness and completion time of asphalt pavement were measured under different precipitation temperature and pavement temperature to detect the ice process of asphalt pavement.The experimental results show that the voltage-time curves measured by fiber-optic ice sensor can be divided into two types, which are related to the thickness of ice.On the whole, with the decrease of pavement temperature, Rain Water temperature below 2 鈩，
