Adherence Study of a Bio-cutback on Prime Coat Services over Different Kind of Bases Layers
Prime coat is a fundamental stage of construction that influences the quality of pavements, especially on low volume roads (LVR). However, the substances released by the materials commonly used in this process can be harmful to the atmosphere and to the workers on construction sites. Thus, it is essential to search for alternative asphalt materials that are less harmful to the environment and to the health of the population. This work aims to evaluate the adherence properties of a bio-cutback composed of an asphalt binder modified by Euphorbia Tirucalli (aveloz) sap, diluted on d-limonene, a vegetable oil obtained from citrus fruit peels, for application on prime coat services, over different types of soil. Through the adherence test, three types of soils (clayey, silty and sandy), primed with three types of binders (medium-setting cutback, asphalt emulsion for priming – EAI, and the bio-binder under study) were analyzed at three rates, and in two different compaction moistures. The results of the adhesion tests showed that the bio-binder presented higher values of adherence than the commercial products, for all types of soil studied, indicating the superior performance of this material in priming services.
