专利汇可以提供Surface applications such as bridge deck covering, pavement patching, roofing applications and other coverings专利检索，专利查询，专利分析的服务。并且A nonheat-sealed polypropylene fabric, e.g., nonheat-sealed nonwoven polypropylene mat or fabric, is used within an asphalt aggregate surface covering. A cutback asphalt or asphalt emulsion is spread, a mat of nonheat-sealed polypropylene fabric is laid into the asphalt, further adhesive can be applied together with aggregate and finally, the mass is smoothed by rolling to make the final surface application covering. Blisters which are formed when using heat-sealed fabric are avoided.，下面是Surface applications such as bridge deck covering, pavement patching, roofing applications and other coverings专利的具体信息内容。

权利要求

1. A surface covering suitable for covering road surfaces, roofs, bridge decks, and the like which comprises an asphalt adhesive, a nonheat-sealed nonwoven polypropylene mat and aggregate laid thereon and smoothed into said fabric and adhesive wherein adhesive completely permeates and impregnates the entire mat and is present in sufficient quantity on top of the mat to receive the aggregate.

2. A method of laying a covering upon a surface which comprises applying an asphalt adhesive coating to said surface, the adhesive coating material when applied being in the fluid state sufficient to penetrate a mat, laying a nonwoven, nonheat-sealed polypropylene mat on said adhesive coating, spreading upon the thus prepared surface a layer of aggregate and then compacting said aggregate into said thus prepared surface, the adhesive being applied in a quantity sufficient to be present on top of the mat to receive a compacted aggregate.

3. A method according to claim 2 wherein the composite of the claim is applied to a bridge surface or deck.

4. A method according to claim 2 wherein there is deposited upon the polypropylene mat which has been laid on said adhesive coating a further quantity of adhesive which further quantity of adhesive permeates into said mat and there is then spread upon the thus prepared surface a layer of aggregate which is then compacted into the adhesive coated mat.
