(2013-11-13)
La mezcla asfáltica en caliente (MAC) es un material compuesto, heterogéneo, integrado por cemento asfáltico (o asfalto), agregados, vacíos y otros aditivos incluyendo cal, fibras, etc., usado predominantemente para la ...
Caracterización dinámica de una mezcla asfáltica sometida a las condiciones ambientales de Bogotá
(2013-11-21)
The paper presents the evolution of the resilient modulus, permanent vertical deformation, and fatigue law of hot mix asphalt (HMA) when exposed to the weather conditions in the city of Bogotá D.C. (Colombia) for 29 months. ...
Modelación del comportamiento reológico de asfalto convencional y modificado con polímero reciclado, estudiada desde la relación viscosidad-temperatura
(2013-11-27)
The rheological properties of asphalt are directly related to its chemical composition, which varies with the origin of crude oil. The rheological behavior of the binder has a significant influence on the properties of the ...
Determinación de las fracciones SARA de asfaltos colombianos envejecidos al medio ambiente empleando cromatografía líquida en columna
(2013-11-12)
In this paper, we present a method based on liquid chromatography column to quantify the chemical composition of asphalt cements manufactured in Colombia, under the environment by determining the SARA fractions. The method ...
