The article expounds some problems and solutions during the construction of asphalt concrete bridge repair and repair for the superstructure repair of the upper part of the Lihu Bridge from the perspective of construction. The construction process of the second coating waterproof layer is introduced emphatically. In order to ensure the specification of the asphalt concrete surface layer, To be achieved by the compaction, smoothness, skid resistance and insulation and other measures taken in winter. After a year of use, the results prove that these measures are effective, the construction quality is good, and no defects occur. It is of considerable reference to the maintenance of asphalt concrete pavement of bridges and super-bridges.
