This research studies the influence of temperature, water, and granulometry in the cohesion of asphalt mixtures.The study was carried out by subjecting dry and wet samples to the UCL test. The research started by characterizing the granular material and three asphalts with different behaviour (60/70, 85/100 and modified with polymer SBS). The grain size curves used correspond to the so established as md10 and md12 by the Instituto de Desarrollo Urbano (IDU). The asphalt optimal percentage was determined via the Marshall apparatus in samples without filler, following UCL test procedures. Several samples were built with the optimal percentage and tested by means of an Angeles Machine at different typical Colombian temperatures in dry and wet state. The results obtained show that the modified asphalt presents a higher cohesion rate than conventional asphalts; that water diminishes the cohesion between the asphalt and the particles irrespective of the granule used, and that the md12 granulometry yield higher losses than the md10 grain size. |
