Novel modified asphalt concrete pavement pouring type construction method for continuous steel box girder bridge deck
The invention discloses a novel modified asphalt concrete pavement pouring type construction method for a continuous steel box girder bridge deck. The novel modified asphalt concrete pavement pouring type construction method comprises the following steps of 1, de-rusting a steel bridge deck through sand blasting; 2, construction of a methacrylic resin waterproof bonding system; 3, laying a lower-layer pouring type asphalt concrete GA10 for construction; 4, constructing the self-repairing type adhesive emulsified asphalt; 5, paving upper layer modified asphalt SMA13; 6, processing transverse seams, longitudinal seams and edges. Compared with the prior art, the method has the advantages that after the advantage of stable performance of MA and the advantage of working efficiency of the GA process are taken into full play, according to the engineering characteristics, in combination with the technical characteristics of MA and GA, the construction mode that the MA pouring type asphalt mixture is mixed by the GA production process is adopted, and the mixture is paved and formed by relying on the mobility of the mixture and does not need to be rolled.
本发明公开了连续钢箱梁桥面新型改性沥青混凝土路面浇筑式施工工法，包括以下步骤：步骤一、钢桥面喷砂除锈；步骤二、甲基丙烯酸树脂防水粘结体系施工；步骤三、铺筑下层浇筑式沥青砼GA10施工；步骤四、自修复型粘接乳化沥青施工；步骤五、铺筑上层改性沥青SMA13；步骤六、横缝、纵缝和边缘处理。本发明与现有技术相比的优点在于：在考虑充分发挥MA性能稳定的优势和GA工艺的工效优势后，根据工程特点，结合MA与GA的技术特点，用GA生产工艺拌和MA浇注式沥青混合料的施工方式，依靠混合料自身流动性摊铺成型、无须碾压。
