Thermal fissuring of asphalt mixtures located in excess of 3500.00 m areas, is generated by the high thermal gradient having pavements height, which generates daily volumetric changes within the asphalt layer, which in turn produce stresses cyclic tension and compression. The thermal fissuring is one of the main types of failure that presented high pavements in Peru, between the months of June and September the winter or "frost" occurs station, where absolute mínimum temperatures down to -20 occur °C in the early hours of the day, while during the day the average ambient temperature rises to 20 °C, the characteristics of these areas low temperatures affect the rheological properties of asphalt and consequently the physical and mechanical properties of mixtures asphalt, causing the fissuring of the asphalt layers, thermal and / or increased stiffness with the combined action of heavy traffic contraction. Asphalt cement is classified as a viscoelastic material that exhibits viscoelastic properties simultaneously, ie a material which is intermediate between the behavior Hooke solid (elastic) and Newton liquid (viscous). At elevated temperatures (> 100 °C), the asphalt cement behaves like a viscous fluid, while at low temperatures (<0 °C) behaves almost like an elastic solid. Asphalt cement behavior indicated in the previous paragraph, can not be adequately characterized with conventional empirical tests, however can be characterized using the concepts correctly rheology. As mentioned the purpose of this is to determine the influence rheology PEN 120/150 asphalt cement in thermal mix asphalt fissuring Peru. In this thesis, the analysis and interpretation of the study results of the rheological properties of asphalt cement PEN 120/150, and their influence on the thermal fissuring of asphalt mixtures in Peru is, according to the Superpave methodology.
