Evaluación técnica de un pavimento utilizando una mezcla con asfalto modificado con grano de caucho
En el mundo, las Mezclas Densas en Caliente (MDC) con asfalto modificado con grano de caucho reciclado (GCR) son ampliamente utilizado en la ingeniería de pavimentos por sus aspectos técnicos y ambientales. Sin embargo, no existe una contribución clara en el diseño de estructuras pavimento flexible. Este trabajo, evaluó la aplicación de una MDC con GCR

Asphalt is a material widely used in the construction of flexible pavement roads. At the global level, the modification of asphalts with polymers has allowed us to obtain materials that meet the characteristics that asphalt by itself would not resist. This work presents the effect of the modification of neat asphalt, with the styrene butadiene styrene (

Medición de módulos resilientes en mezclas asfálticas con asfaltos modificados grado PG-76 y PG-82
At present efforts to build better roads and more durable, he has led engineers to investigate new materials for the construction of better designed Asphalt Mixture; ie try to characterize in a better way to decipher their behavior in the field. This is not easy, since the materials for building mixtures, both the stone aggregate and asphalt, are ...

The rate of vehicular growth and biodiversity of climates present in Ecuador influence the wear of flexible pavement, prompting to explore new mechanisms of action to improve them. For this reason, this research focuses on the use of rice husk ash (RHA) in AC20 asphalt cement, with the objective of evaluating its physical-mechanical properties, through
