| 摘要 |
<p>The invention concerns a composite bitumen/resin emulsion for producing a layer to protect road surfaces against damage caused by oil derivatives, produced from a first emulsion comprising a resin and a second emulsion comprising a bituminous binder and a resin hardener. A pigment preparation and/or a filling agent consisting of a filler or sand or fine sand or combinations thereof can be incorporated in the first emulsion, the second emulsion or in the composite emulsion resulting from the mixture of the two emulsions. The filled composite emulsion enables to produce road surfaces of thin films in one or several layers.</p> |
