    summary
    Se plantea un proyecto de I+D para la obtención de pavimentos urbanos eco-eficientes, a partir de áridos reciclados mixtos procedentes de la valorización de RCD._x000D_ El objetivo consiste en sustituir el 100% de los agregados naturales presentes en los pavimentos actuales (prefabricados de hormigón) por áridos reciclados mixtos procedentes de residuos de la construcción y demolición, cumpliendo todos los parámetros normativos en cuanto a absorción de agua, resistencia a flexión y resistencia al desgaste por abrasión, según la norma UNE EN 1340. _x000D_ P.H. Montalbán y Rodríguez S.A. será la primera empresa española que consigue una línea de productos 100% reciclados a partir de Residuos de la Construcción y Demolición mediante una producción sostenible. Hasta este momento sólo se están comercializando pavimentos urbanos en los que se están sustituyendo aproximadamente un 20% de los áridos naturales, y, en algunos casos aislados alcanza un 30%, pero no son sustituidos por áridos mixtos procedentes de RCD, sino por polvo de mármol o áridos procedentes del machaqueo del hormigón que tienen una mayor homogeneidad, calidad y menor disponibilidad. El nuevo proceso productivo debe ser estable y capacitado para conseguir pavimentos ecoeficientes realizando mínimos recálculos cuando la heterogeneidad de los RCD sea más elevada._x000D_ El reto tecnológico reside en el control de la variables principales que afectan a la estabilidad de las amasadas ya que la utilización exclusiva de RCD amplía el rango de porosidad y el tamaño de las partículas que la componen (densidad específica de 1.7 a 3.0 Kg dm-3 y absorción de agua de 0 a 20.6%) que limita su uso como árido estable._x000D_ Participa en este proyecto el Grupo de Investigación, Física de Radiaciones y Medio Ambiente, FRYMA, de la Universidad de Huelva.

    An R & D project is proposed to obtain eco-efficient urban pavements, from mixed recycled aggregates from the recovery of RCD._x000D_ The objective is to replace 100 % of the natural aggregates present in current (prefabricated concrete) pavements with mixed recycled aggregates from construction and demolition waste, meeting all regulatory parameters in terms of water absorption, bending resistance and abrasion wear resistance, according to UNE EN 1340. _x000D_ P.H. Montalbán y Rodríguez S.A. will be the first Spanish company to obtain a line of 100 % recycled products from Construction and Demolition Waste through sustainable production. So far only urban pavements are being marketed in which approximately 20 % of natural aggregates are being replaced, and in some isolated cases it reaches 30 %, but is not replaced by mixed aggregates from RCD, but by marble or aggregate powder from the crushing of concrete which have greater homogeneity, quality and lower availability. The new production process must be stable and able to achieve ecoefficient pavements by performing minimal recalculations when the heterogeneity of the RCD is higher._x000D_ The technological challenge lies in the control of the main variables that affect the stability of the kneadings since the exclusive use of RCD extends the range of porosity and the size of the particles that compose it (specific density from 1.7 to 3.0 Kg dm-3 and water absorption from 0 to 20.6 %) that limits its use as stable aggregate._x000D_ Participates in this project the Research Group, Radiation Physics, and the University.
