| contents | Influence of four non-conventional additives on the physical, rheological and thermal properties of an asphalt Miguel G. Delgado-Jojoa Jessica A. Sánchez-Gilede Hugo A. Rondón-Quintana Wilmar D. Fernández-Gómez Fredy A. Reyes-Lizcano Ingeniería Husil Gilsonite crumb rubber Modified asphalt low density polyethylene waste This article shows the evaluation of the influence of two polymer wastes (crumb rubber - GCR and low density polyethylene - LDPE), a natural bitumen (Gilsonite - G) and a chemical component (Husil) on the physical, rheological and thermal properties of an asphalt cement (AC 60/70 penetration grade). Over a control asphalt and the modified asphalts were performed: penetration, softening point, ductility, ignition point, rheology (using a dynamic cut rheometer - DSR), Multi Stress Creep and Recovery (MSCR), linear amplitude sweep (LAS), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) tests. The results show that the four additives increase the stiffness and rutting resistance of the asphalts. Additionally, it reports an increase in fatigue cracking resistance when asphalt cement is modified with GCR, G and Husil. The additives give thermal stability to the asphalt cement, providing less mass loss (linked mostly to a less oxidation). 2018 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64358073003 https://www.redalyc.org/journal/643/64358073003/ https://www.redalyc.org/journal/643/64358073003/html/ https://www.redalyc.org/journal/643/64358073003/64358073003.epub https://www.redalyc.org/journal/643/64358073003/movil 10.15446/ing.investig.v38n2.68638 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.2 Vol.38 |
