Abstract

This work consists of the geotechnical characterization of the sand of the beach of Ponta Negra, main tourist point of the city of Natal and the state of Rio Grande do Norte, where is the main postcard of both, Morro do Careca.

The research was divided in steps, field recognition and definition of the representative points of collection of the material in homogeneous stretches, being essential a walk along the study area, and another stage, laboratory, with the accomplishment of the tests of specific mass, sieving and maximum and minimum void indices.
