截至2015年3月底,云南省全省已经通车的高速公路已经达到3255km,预计2015年底公路公路的通车里程将突破4000km,未来5年云南省还将再建设约4000km高速公路。为分析水泥混凝土路面在云南省应用的现状和前景,根据云南省的地形、交通特点以及资源的分布特点,说明发展水泥混凝土路面不仅可以充分利用云南省的水泥产能,并且使用石灰岩集料可以降低水泥混凝土路面的温度翘曲应力水平。本文分别从经济与技术的角度分析了在云南省推广水泥混凝土路面应用的可行性。
As of the end of March 2015, the number of expressways in Yunnan province that have been opened to traffic has reached 3,255km. It is estimated that the mileage of highway roads will exceed 4,000km by the end of 2015 and approximately 4,000km of expressways will be built in Yunnan Province in the next 5 years. In order to analyze the current situation and prospect of cement concrete pavement application in Yunnan Province, according to the topography, traffic characteristics and resource distribution characteristics of Yunnan Province, it shows that the development of cement concrete pavement can not only make full use of cement production capacity in Yunnan Province, but also reduce the use of limestone aggregate Temperature warping stress level of cement concrete pavement. This article analyzes the feasibility of promoting the application of cement concrete pavement in Yunnan Province from the economic and technical perspectives.
