It was sought with an accomplishment of this article to identify an influence of the type of fines, evaluated according to a MCT classification, in the resilient characteristic of tropical soils that has a passive percentage in the sieve nº 10 between 50 and 97%, such soils can not, A rigor, a qualified methodology of 100% of the material passing through the No. 10 sieve, with 2mm aperture, but there are strong indications, such as cracking after an execution, requiring a great influence of the type According to an MCT classification in behavior Of material type. Also, the type of thin classification with a resilient modulus range was related, since the resilience module represents one of the fundamental input parameters for the mechanistic design of pavements. For the proposed objectives, 662 soils of various granulometries and provenances were studied, allowing the end of the research to obtain the type of relationship between a classification of the fines and the resilient behavior of the studied soils.
