沥青路面温度场分布规律与理论经验预估模型
Temperature distribution and method-experience prediction model of asphalt pavement
摘要
Abstract
In order to predict asphalt pavement temperature in the natural environment, the key factors of pavement temperature were determined based on the principle of heat transfer solar radiation. The distribution of pavement temperature was analyzed based on the field test results. Further, the method-experience prediction model of pavement surface was established with dimensional analysis by taking correction factors in the model into consideration. Then, the model was used to predict the asphalt pavement temperature distribution in Hainan and analyze the influence of natural factors on pavement temperature. The research results show that when the pavement temperature is predicted with the factors of July, the average relative error of this model in different depths is less than 5%; When the pavement temperature is predicted with the factors of August, December and January, the average relative error of this model in different depths is less than 10%; Maximum relative error generally occurs at low temperature period; Air temperature is the major factor on pavement temperature distribution in the whole day, while solar radiation is the main factor on pavement highest temperature; and the impact of wind speed on pavement temperature can not be neglected.关键词
