2025-01-30T12:53:06Z urn:hdl:10259/10106 Introduction of recycled polyurethane foam in mastic asphalt Salas García, Miguel Ángel Pérez Acebo, Heriberto Polyurethane foam Mastic asphalt Bitumen modifier Polymer modified bitumen Indentation test 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. 2025-01-30T12:53:06Z 2025-01-30T12:53:06Z 2018 info:eu-repo/semantics/article 0350-2465 http://hdl.handle.net/10259/10106 10.14256/JCE.2181.2017 1333-9095 eng Građevinar. 2018, V. 70, n. 5, p. 403-412 https://doi.org/10.14256/JCE.2181.2017 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional Croatian Association of Civil Engineers
