Problems solved by technology

[0006] At present, poured asphalt concrete + SMA and double-layer epoxy asphalt concrete are the main pavement methods for bridge deck pavement. The cast asphalt concrete + SMA pavement system has excellent low temperature and fatigue performance, but the high temperature anti-rutting performance is not ideal; Epoxy asphalt concrete has excellent high-temperature performance, but its low-temperature cracking resistance is poor

Embodiment 1

[0024] Deck steel material, parts by mass basis, relationship between the ratio of: 100 parts of polyarylene sulfide, polycarbonate 54 parts, 3 parts of agent, initiator and acrylonitrile - butadiene - styrene copolymer 21 parts ; the polyarylene sulfide is polyphenylene sulfide, the grafting initiator is maleic anhydride.

[0025] The method of preparation of the steel deck material, the specific steps:

[0026] (1) A polyarylene sulfide into horizontal stirring mixer, open stirring, was slowly added maleic anhydride; successively added to the polycarbonate, an acrylonitrile - butadiene - styrene copolymer, at 20 revolutions / min speed stirring 22min;

[0027] The resulting (2) in step (1) was added pulverizer into powder;

[0028] (3) Step (2) The resulting powdery mixture was added pre-heated to 190 deg.] C in a twin-screw extruder, extruded, cooled to room temperature, granulated, i.e., too.

Embodiment 2

[0030] Deck steel materials, in parts by mass, the ratio relationship: polyarylene sulfide 60 parts, 10 parts of a polycarbonate, a graft initiator, and 1 part of acrylonitrile - 50 parts of styrene - butadiene ; polyarylene sulfide is a polyarylene sulfide sulfone, the grafting initiator is maleic anhydride.

[0031]The preparation method of the steel bridge surface material is:

[0032] (1) Insert the polyarylene ether into the horizontal stirring mixer, stir the stirring, slowly add maleic anhydride; sequentially add polycarbonate, acrylonitrile-butadiene-styrene copolymer, 10 rpm / min speed Take it for 30 min;

[0033] (2) The mixture obtained by step (1) is added to the pulverizer to pulverize the powder;

[0034] (3) The powder mixture obtained by step (2) is added to a two-screw extruder preheated to 180 ° C, extruded, cooled to room temperature, granulation,

Embodiment 3

[0036] Steel bridge paving materials, with mass sharing, ratio of 10 parts, polyalcarbonate, 100 parts of polycarbonate, 2 parts of grafting initiator and acrylonitrile-butadiene - styrene copolymer 36 parts The polyarylene sulfide is polyphenylene sulfide, the graft initiator being a maleic anhydride.

[0037] The preparation method of the steel bridge surface material is:

[0038] (1) In the horizontal stirring mixer, the polyarylene ether is placed in a horizontal stirring mixer, and the stirring is opened, and the maleic anhydride is slowly added; the polycarbonate, acrylonitrile-butadiene-styrene copolymer is added, and the speed of 30 rpm / min Stirring is stirred for 15 min;

[0039] (2) The mixture obtained by step (1) is added to the pulverizer to pulverize the powder;

[0040] (3) The obtained powder mixture obtained by step (2) is added to a twin screw extruder preheated to 200 ° C, extruded, cooled to room temperature, granulation,
