Mechanical Behavior of Asphalt Mixtures in Regions of Low Temperature and Altitude Above 3800 Meters

This paper shows the results obtained from a laboratory test on the mechanical behavior of asphalt mixtures that were subjected to the Peruvian altitude climate for the application of pavement construction. A case study was performed at Juliaca Airport, Puno, which is located at an altitude of 3,800 meters and presents behavior peculiarities in the pavement structure because of the combination of climatic demands and the high level of the water table and soils in the subgrade. The results are presented that concern the resilient modulus and rutting of asphalt mixtures with conventional Peruvian asphalt, which is normally employed at worksites in the region studied. A comparison is also made with the results obtained with the same asphalt modified by 4% of styrene butadiene styrene (SBS) polymer.
