Estudo da obtenção de pavimento asfáltico a partir da mistura de bioasfalto e polímero do tipo Ret

Abstract

The road mobility is the main locomotion option services and people in the country due to its ease of access and low cost. However, Brazil, even though it contains an extensive road network, needs roads with optimal quality to withstand the heavy traffic efforts to which they are subject, knowing that the implementation and maintenance of asphalt pavements on roads is of great importance for the progress of an area, optimizing the entire process of shifting and transport. For the production of asphalt, the main route is from petroleum refining, but there are other relatively technological routes capable of producing this material from a renewable source, one being the cracking route vegetable oils, which generates a product rich in hydrocarbons called Liquid Organic Product (PLO). In the present study was investigated obtaining a biopavement from the asphalt binder mixture derived from the distillation of the PLO, with a Reactive Elastomeric Terpolymer (RET) Elvaloy®, aiming acceptable properties in Brazilian standards for paving. The bottom product generated in the PLO distillation processes has been characterized before and after being added Elvaloy®, determining its density and chemical composition. Subsequently, the two asphalt binders have been used in the manufacture of Marshall test specimens in order to determine their stability as asphalt pavement. It may be highlighted that the two types of binders with and without polymer present in the density range provided for by current regulations. Moreover, it was proven the high amount of carbon element in the range 85-95% in these materials, which confirms the potential of the product to obtain the Asphalt Cement. However, from the Marshall stability test, it was observed that the bottom product used not completely satisfied its use as a Asphalt Cement due to low stability found in this test. The most viable alternative use for this type of material would possibly like lubricating oil due to its physicochemical characteristics.
