ABSTRACT:

This paper presents the results based on a thorough study of the mechanical properties of hardened recycled mixtures with emulsion made continuously at a rate of reuse 100% plant and 70% (TEN 100 and RTE 70, respectively), being suitable for layering rolling on urban roads. The obtained values ​​of modulus, indirect tensile strength, bitumen content, grain size, percent void in mixture, water sensitivity and track test, which reveal that are mixtures with properties similar to those of mixtures conventional hot, resulting in a promising technology for use in the rehabilitation of city streets.
