Soon, all there is different degrees of disease, car in one problem of road and bridge beam worker research, domestic many paving steel bridge decks
Rut, passage, cracking etc..
What domestic application was more at present mainly has three kinds of schemes：
1st, cast asphalt concrete is mated formation, and temperature is up to 210-260 DEG C when pouring asphalt concrete is mated formation, and steel plate is easy
Temperature distortion, very high can be required to the deformation compliance of pavement material, be easier crack occur.Meanwhile spread using self drainage
The pouring asphalt concrete of dress can not mat formation on the larger Steel Bridge Deck of the gradient.
2nd, epoxy asphalt concrete is mated formation, however, epoxy asphalt concrete is mated formation, requirement bridge floor is without any impurity, dust
And moisture, and need after the completion of construction two months or so time could open to traffic, implementation condition is harsh, past in practical application
It is past to fall flat.
3rd, common SMA bitumastics concrete pavement, but the Coating combination problem of common SMA concrete and steel plate is not
Can preferably be solved, modified asphalt viscosity is relatively low, causes anti-shear concrete ability inadequate, easily occurs elapsing etc. existing
As.
