至2008年底,广西建成高速公路达2 181 km,大幅度提高了公路运输能力和效率,对促进经济社会快速发展作出了重要贡献。按照广西高速公路网新的规划,未来的20年,其密度将达到每100 km~2有3.18 km高速公路,超过多数发达国家目前水平,而水泥混凝土路面施工量也将随之加大。文章认为,在循环经济学理论的指导下和高科技的引领下,新型绿色水泥混凝土将是保证高速公路路面施工质量的关键所在。
By the end of 2008, Guangxi built up 2,181 km of expressways, which greatly improved the capacity and efficiency of road transport and made important contributions to the rapid economic and social development. According to the new plan of Guangxi Expressway Network, the density will reach 3.18 km / 100 km ~ 2 in the next 20 years, exceeding the current level in most developed countries, and the construction volume of cement concrete pavement will also increase. The article believes that under the guidance of the theory of circular economy and under the guidance of high-tech, the new green concrete will be the key to ensure the quality of highway pavement construction.
