The paper presents the change that undergo the Marshall Stability and Flow of hot mix asphalts (type MDC-2) when they are exposed to weather of Bogota D.C. The mixes were performed and evaluated employing the two typical asphalt cements (AC) produced in Colombia by ECOPETROL: AC 80-100 from Barrancabermeja and AC 60-70 from Apiay. Marshall Stability and Flow of the mixes were measurement each three months during one year in order to obtain its evolution with the time. The general conclusion was that the behavior of the mixes depends of the AC used. Additionally, the tendency of hot mix asphalts is increase the values of Marshall Stability and Flow when the asphalt mixtures are exposed to weather of Bogota D.C.
