黄藏寺水利枢纽对外道路路面结构形式论证

Argument of External Road Surface Structure Type of Huangzangsi Water Conservancy Project

在设计黄藏寺水利枢纽对外道路工程路面结构形式时,依据对外道路使用功能以及主体工程建设的特点,选取了泥结碎石路面、水泥混凝土路面以及沥青混凝土路面的3种不同的建设设计方案,从工程投资、施工速度、改建养护等方面对各方案进行比选,推荐采用了永久和临时相结合的路面结构型式。即,施工期间,采用泥结碎石临时路面;运营期间,改建为沥青混凝土路面。

When designing the external road structure of Huangzangsi water conservancy project, according to the external road use function and the main project construction features, three different schemes of clay-bound macadam pavement, cement concrete pavement and asphalt concrete pavement are selected.Compared with other schemes in terms of project investment, construction speed, reconstruction and maintenance, the pavement structure type of forever-temporary combination is recommended. That is, using the clay-bound macadam pavement during the construction period, using the asphalt concrete pavement during the operation period.
