Abstract

The invention relates to the field of bridge deck pavement, and discloses a high-molecular polymer ultrathin wear-resistant protective bridge deck pavement and a construction method thereof. The high-molecular polymer ultrathin wear-resistant protective bridge deck pavement is prepared from modified acrylic emulsion and aggregate, and the aggregate contains powder, coarse whiting, zinc stearate and acid pickling quartz sand. The bridge deck pavement is good in wear resistance, high in flexural and compressive strength and ultrathin in coating structure, the thickness of the bridge deck pavement is 5-20% of the thickness of a traditional bridge deck, the bridge load weight can be reduced by 80-95% compared with the traditional bridge deck pavement, the service life of a bridge is prolonged,the bridge manufacturing cost is reduced, and meanwhile the safety of the bridge is improved; the pavement is high in ultraviolet resistance and aging resistance, the durability of the pavement is 3-5 times that of a traditional pavement, the rolling resistance of the pavement is improved, and the long-term service life of the pavement is prolonged; the pavement is non-toxic, harmless, pollution-free, non-combustible, non-combustion-supporting and free of fire hazards; later maintenance is simple, only local repair is needed, the manufacturing cost is low, traffic is not affected, a large amount of building slag treatment is not needed, later maintenance cost is greatly reduced, and environmental protection and energy conservation are achieved.

Description

technical field [0001] The invention relates to the field of bridge deck pavement, in particular to a high molecular polymer ultra-thin wear-resistant protective bridge deck pavement and a construction method thereof. Background technique [0002] Bridge deck pavement refers to the protective layer paved on the bridge deck, which prevents the wheels from directly wearing the bridge deck, and also provides a flat and non-slip driving surface for vehicles to prevent corrosion and water seepage of the bridge deck. [0003] The basic requirements for bridge deck pavement are as follows: [0004] 1. Light weight: The increase in the thickness of the bridge deck pavement generally cannot increase the overall rigidity of the bridge structure, but increases the dead load of the bridge, especially for long-span bridges, the weight of the bridge deck pavement is more It has a great impact on the economy and service life. Therefore, the bridge deck pavement is required to be as thin ...
