Preparation equipment used and method are taked the processing step identical with embodiment 13.
Adopt identical detection method among the embodiment 1, after testing, the puncture result is 0.8mm; The water-intake rate result is 4.2%, all coincidence detection technical requirementss.
Water-intake rate reduces behind natural rock asphalt and the trevira, compacting intensity increases, anti-puncture ability significantly strengthens, and can be good at protecting the bottom water-proof material not to be destroyed thereby proof, this water-proof material protecting sheet add.
The contrast experiment: be ready to two parts of samples respectively, the A kind paves waterproof layer and lays hot-mixed asphaltic concrete then carry out compacting on Cement Concrete; The B kind paves waterproof layer and lay the water-proof material protecting sheet then on Cement Concrete, re-lays hot-mixed asphaltic concrete and carries out compacting.
After two parts of sample productions were finished, the waterproof layer and the hot-mixed asphaltic concrete of A kind sample merged, and waterproof layer is penetrated by bituminous concrete, does not reach the waterproof action of expection; The waterproof layer of B kind sample does not have destroyed, and protective shield is intact after compacting, is not penetrated, and Bao Hu water-proof material effectively makes bridge floor after the laying play the waterproof effect of expection under the effect of water-proof material.
The present invention does not describe part in detail, is those skilled in the art of the present technique's known technology.
