RONDON QUINTANA, Hugo Alexánder; RODRIGUEZ RINCON, Edgar  and  MORENO ANSELMI, Luis Ángel. MECHANICAL RESISTANCE OF HOT THICK MIXTURES MADE WITH ASPHALT MODIFIED WITH POLYVINYL CHLORIDE, POLYCLORURE (PVC) WASTES, HIGH DENSITY POLYETHYLENE (PEAD), AND POLYSTYRENE (PS) EVALUATED IN MARSHALL ASSAY. Rev. ing. univ. Medellin [online]. 2007, vol.6, n.11, pp.91-104. ISSN 1692-3324.

The main objective of this research Project was to evaluate in a laboratory the change in mechanical strength that dense hot asphalt mixtures go through when waste polymeric additives of plastomeric type (polyvinyl chloride, high density polyethylene and polystyrene) are added to asphalt cement, by 'wet way'. This change was evaluated using Marshall Test. The general conclusion of the experimental results was that modified hot asphalt mixtures present better mechanical behavior than conventional mixtures (mixtures which use asphalt without additives).

Keywords : Modified asphalts; vinyl polychlorure; and high density polyethylene; polystyrene.
