Abstract

Método para colocación de hormigón compactado a rodillo (HCR) sobre una subbase para producir un pavimento de hormigón, caracterizado por que comprende: (a) dosificar un hormigón que tenga una consistencia seleccionada del grupo que consiste en S1, S2, S3, S4 y S5 de acuerdo con la norma europea EN 206-1: 2000 y cargar dicho hormigón en un camión de transporte de hormigón, (b) añadir al menos un agente de peletización seleccionado del grupo que consiste en celulosa, quitosano, poliacrílicos, poliaminas, poli(alcoholes vinílicos), polisacáridos, colágeno, acrilamida, ácido láctico, ácido metacrílico, metacrilato, hidroxietilo, etilenglicol, óxido de etileno, ácido acrílico, floculantes inorgánicos y coagulantes inorgánicos para el hormigón y en espera de 3 a 15 minutos en mezcla constante para producir un hormigón peletizado con un tiempo VEBE clasificado como V0 a V2 de acuerdo con la norma europea EN 12350-3: 2009 y (c) descargar el hormigón peletizado obtenido en la etapa (b) sobre la subbase desde el camión de transporte de hormigón, girando el tambor del camión de transporte de hormigón.

La grava, cemento, agua, superplastificante y retardante se mezclaron durante 3 minutos en el sitio de trabajo. El agente de peletización se añadió luego y los componentes se mezclaron adicionalmente durante 5 minutos. Se formaron los pellets durante este período.
5 Los pellets formados se vertieron desde el cubo en el hueco para lograr una capa de 3-4 cm. El hormigón se extendió con un rastrillo para lograr una altura uniforme. La compactación final se realizó manualmente, con la ayuda de una pala.
