In order to achieve the stabilization of pavements, emerge new technologies of stabilizing agents such as foamed bitumen and asphalt emulsion. In the Roadway Project Dv-Humajalso-Desagüadero and Tacna-Capazo-Mazocruz, the technical solution was to apply foamed bitumen in road Section 7 Tarata-Capazo. Thermodynamic condition is fundamental where foamed bitumen is evidenced in Section 7, the temperature is lower than 5 °C, so the asphalt don’t disperse on the Mastic, causing an agglomeration of asphalt in the form of chewing gum and making impossible the compaction of the pavement layer. In this problem, It’s proposed to stabilize the granular material with asphalt emulsion, so the asphalt particles are dispersed in a solution to 25°C. The technique is a mixture of cold asphalt and is feasible for the critical thermodynamic conditions of the Section 7 Tarata-Capazo. The objective is to achieve the stabilization of the pavement using asphalt emulsion. The design of the cold asphalt mix applies the Illinois Methodology to determine the optimum quantity of residual asphalt. So that, the design of the pavement is done with the methodology of AASHTO 93, which allows to determine the thicknesses of the pavement layers that will satisfy the serviceability and traffic for the useful life of the project. Finally, It´s possible to validate the stabilization of the pavement in the field with the compaction and deflectometry controls, demonstrating the versatility of the emulsion as a cold asphalt mixture against the critical thermodynamic conditions of the Project.
