Over the years, many types of sidewalk coatings have been present in the area of paving applied to civil engineering, currently, among the various types of flexible sidewalks existing today, the flexible sidewalk made based ...
Estudo laboratorial das propriedades mecânicas de misturas com diferentes cimentos asfálticos de petróleo produzidos no Brasil
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-02-28)
The evaluation of the behavior that different petroleum asphalt cements (CAP) give to the
mixtures becomes important due to the direct relationship between the quality of the
pavement and the performance of the binder. ...

Influencia de la temperatura y el tiempo de mezclado en la modificación de un cemento asfáltico
(Universidad Santo TomásMaestría Infraestructura VialFacultad de Ingeniería Civil, 2019-07-16)
Based on the literature consulted to date, when an asphalt is modified wet with thermoplastic polymers (elastomers or plastomers), a remarkable increase in its rigidity is usually obtained, expressed through the decrease ...
Mechanical properties evaluation of a hot asphalt mixture modified with asphaltite
The strength under monotonic load, resilient modulus and rutting were evaluated on a hot-mix asphalt (HMA) modified with a natural asphaltite. Additionally, the influence of the environmental conditions of Bogotá D.C., was ...
