Abstract: In the construction industry nowadays, it is the concepts such as sustainability, recycling, emission and energy reduction which are coming to the fore. This article follows the same path, looking at the design of new, recycled road subbase layers. These layers are almost 100% composed of recovered reclaimed asphalt, crushed to the appropriate fraction. This reclaimed asphalt is either mixed with a suitable binder, heated to a low temperature, or a combination of both effects occurs. The research described in this paper is partially related to the newly developed standard ČSN 73 6147 Cold recycling of pavement structural layers [1]. The aim of this research is to economically and environmentally reuse reclaimed asphalts of lower quality, specifically in the subbase layer of pavements. Otherwise, this precious material is mainly used for the backfilling of roadsides.
Keywords: bitumen emulsion/cement bonding; cold recycling; Reclaimed asphalt; subbase layer; warm recycling
