Salas García, Miguel Ángel Pérez Acebo, Heriberto 2025-01-30T12:53:06Z 2025-01-30T12:53:06Z 2018 0350-2465 http://hdl.handle.net/10259/10106 10.14256/JCE.2181.2017 1333-9095 The aim of this paper is to analyse the suitability of recycled polyurethane (PU) foam as a binder modifier in mastic asphalts (MA). The results show that harder bitumen is achieved with an increasing percentage of PU, up to 5 %, when the workability of the sample becomes poor. A MA mix with a 4 % of PU in bitumen was manufactured. A lower indentation was observed when compared to a virgin sample, and it was established that the modified MA can be used on heavy-traffic roads. These results suggest a promising use of this waste polymer. application/pdf eng Croatian Association of Civil Engineers Građevinar. 2018, V. 70, n. 5, p. 403-412 https://doi.org/10.14256/JCE.2181.2017 Atribución 4.0 Internacional http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Polyurethane foam Mastic asphalt Bitumen modifier Polymer modified bitumen Indentation test Materiales de construcción Building materials Introduction of recycled polyurethane foam in mastic asphalt info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Građevinar 70 5 403 412
