Influencia de la granulometría en la resistencia al ahuellamiento de mezclas asfálticas

The geotechnic engineering research group of the Universidad M. Nueva Granada, carried out a research about the performance of different bi- tuminous mixes under the wheel tracking test when their gradations changes in the upper, middle and lower layer. Two sets of mixes were studied belonging to the Instituto Nacional de Vias (INVIAS) and the In- stituto Distral Urbano (IDU).
