Study of the Effect of Climatic Factors on Indirect Tensile Strength of Asphalt Mixtures Modified with a Mixture of /Polymer-Sulfur/

The asphalt paver must fulfill a set of basic requirements, from sufficient bearing capacity for the expected loads, stability and good resistance to deformations resulting passage large loads at high temperatures, also securing an impermeable surface that achieves adequate drainage water. Hence, it is necessary search permanently continuously improved materials are resistant influence factors affecting flexible paving in its upper layers, consisting bituminous composites. Polymer-modified bitumen has been used improve performance paving. I have designed mixtures using cement without modification, polymer-modified (polyethylene), modified with mixture (polymer-sulfur). Next, performed lab experiments simulating effect investment, weather climatic during operation investment (conditioning test). It concluded change value indirect tensile Strength Asphalt samples formed which /polymer-sulfur/ was (4%) after conditioning test, as polyethylene (PE), (14%) test (PE) test.
