Abstract

The invention relates to a heating system for epoxy asphalt steel bridge deck pavement and a pavement method. The heating system can be used for controlling the operation temperature in the epoxy asphalt steel bridge deck pavement process, thereby shortening the curing time of epoxy asphalt, further greatly shortening a construction period and reducing the maintenance time before the opening to traffic. Simultaneously, the invention provides a pavement method using the heating system for epoxy asphalt steel bridge deck pavement; and the pavement method can enable the epoxy asphalt steel bridge deck pavement to be constructed in winter and can also be adopted in summer when fast curing is needed.

Description

technical field [0001] The invention relates to a heating system for paving an epoxy asphalt steel bridge deck and a method for paving an epoxy asphalt steel bridge deck by using the heating system. Background technique [0002] The steel bridge deck has the characteristics of reducing dead load and exerting space structure, and is the preferred structural form of long-span bridges. But at the same time, steel bridge decks are characterized by smoothness, flexibility, large local deformation, complex dynamic characteristics, and small heat capacity, which also impose strict requirements on bridge deck pavement. [0003] Compared with cement concrete pavement, asphalt pavement has the characteristics of lightness, softness, waterproof, and easy repair. It is the preferred material for steel bridge deck, especially long-span steel bridge deck pavement, and has been widely used at home and abroad. In terms of materials, asphalt paving has also developed rapidly from traditiona...
