Abstract

Procedimiento de recubrimiento de los áridos con productos bituminosos. Se describe un nuevo procedimiento para mejorar la adhesividad de los productos bituminosos sobre los áridos, cuando se utilizan emulsiones acuosas de dichos productos bituminosos para el asfaltado de carreteras o la impermeabilización de estructuras constructivas. El procedimiento consiste en añadir a las emulsiones bituminosas, ya formadas, antes de su empleo, o directamente a los áridos, antes de su recubrimiento con la emulsión, una disolución de ésteres fosfóricos en disolventes polares. El procedimiento descrito evita los problemas derivados de la falta de estabilidad de las emulsiones bituminosas a las que se ha incorporado el aditivo directamente al betún antes de formar la emulsión, conocidas por la técnica anterior, y proporciona un método de asfaltado mucho más sencillo, versátil y eficaz que los descritos anteriormente.Procedure for coating aggregates with bituminous products. A new procedure is described to improve the adhesiveness of bituminous products on aggregates, when aqueous emulsions of said bituminous products are used for asphalting roads or waterproofing construction structures. The procedure consists in adding to the bituminous emulsions, already formed, before use, or directly to the aggregates, before being coated with the emulsion, a solution of phosphoric esters in polar solvents. The described procedure avoids the problems derived from the lack of stability of the bituminous emulsions to which the additive has been incorporated directly to the bitumen before forming the emulsion, known in the prior art, and provides a much simpler, more versatile asphalting method. and effective than those described above.
