Abstract

The invention belongs to the technical field of pavement, and discloses a steel bridge deck pavement layer and a preparation method thereof. The steel bridge deck pavement layer comprises an adhesivelayer, a composite layer and an anti-sliding and wear-resisting layer. The thickness ratio of the composite layer and the anti-sliding and wear-resisting layer is 0.4: As that anti-skid and wear-resistant lay of the invention is formed by mix and solidifying emulsion and aggregate, The aggregate part is embedded in the emulsion, and part of the aggregate is exposed on the emulsion surface. After the aggregate is cured, the bare aggregate forms a rough surface, increases the friction with the contact surface of the vehicle tire, improves the skid resistance performance of the pavement layer, makes up for the defect that the skid resistance performance of the composite material layer is low, and improves the safety of driving; In addition, the contact surface between fine-grained aggregate particles is larger, the coupling force is stronger, the strength is higher, the abrasion resistance force is stronger, and the service life of the pavement is prolonged.

Description

technical field [0001] The invention belongs to the technical field of pavement pavement, and in particular relates to a steel bridge pavement and a preparation method thereof. Background technique [0002] Steel box girder bridges have the advantages of light weight, convenient erection, and large spanning capacity, and are widely used in municipal engineering and long-span structures such as crossing rivers and seas. Bridge deck pavement is a layer of material structure paved on the surface of steel box girder bridges that protects the bridge structure, distributes the concentrated load of the wheels, and satisfies the functions of driving. Due to the large deformation of the steel structure, asphalt concrete with good toughness is generally used for the pavement of the bridge deck. However, the properties (such as elastic modulus, thermal conductivity and thermal expansion, etc.) When the traffic and driving load change greatly, the pavement structure is easily deformed,...
