Environment-friendly asphalt structure and construction method thereof
The invention discloses a thin-layer asphalt overlay construction and joint treatment method for an airport parking apron cement pavement. The asphalt overlay structure comprises a cement concrete pavement, a thermosetting modified asphalt macadam sealing layer and an asphalt concrete overlay layer from bottom to top. The method comprises the following steps: (1), treating cement concrete pavementdiseases; (2), milling and planing the cement concrete pavement; (3), performing construction of a thermosetting modified asphalt macadam sealing layer; (4), constructing a cover surface layer; and (5), performing cover surface layer joint cutting and joint pouring construction. Binding materials adopted in the step (1), the step (3) and the step (4) are normal-temperature thermosetting modifiedasphalt of different formulas, and joint sealing materials adopted for joint sealing are silicone sealants. The binding materials are used at normal temperature, so that the energy consumption and waste gas emission during production, paving and compaction of the hot-mixed asphalt mixture are greatly reduced, and the environmental pollution is reduced.
本发明公开了一种用于机场停机坪水泥道面的薄层沥青罩面施工和接缝处理方法，所述的沥青罩面结构自下而上包括水泥混凝土道面、热固性改性沥青碎石封层和沥青混凝土罩面层；采用如下步骤：(1)水泥混凝土道面病害处理；(2)水泥混凝土道面的铣刨；(3)热固性改性沥青碎石封层施工；(4)罩面层施工；(5)罩面层切缝和灌缝施工。其中，(1)、(3)和(4)中采用的粘结料和结合料为不同配方的常温型热固性改性沥青，灌缝采用的填缝料为硅酮密封胶。本发明的粘结料和结合料的使用均在常温下进行，大大降低了热拌沥青混合料生产及摊铺、压实时的能源消耗和废气排放，减少了对环境的污染。
