GEOPHYSICAL AND GEOTECHNICAL APPROACH TO CHARACTERIZE A CONSTRUCTION AND DEMOLITION WASTE

Research objectives:

This study aims to determine the geological and geotechnical characteristics of an anthropogenic deposit, which consists of a construction and demolition waste landfill.

Method overview:

The method encompassed: mapping, with a sample collection was carried out; determinations of soil penetration resistance, with a dynamic penetrometer, which was used to determine the penetration resistance of the surface layers of the landfill and surrounding natural material areas; hydraulic conductivity determination; electrical resistivity property using geophysics and particle size analysis.

The following data items were made available:

1. Geophysics: They content a list of apparent resistivity due to the heterogeneity of the medium. For the survey, five parallel lines were used.
2. Hydraulic conductivity: It contents a list with the results of measuring the water´s lowering speed.
3. Dynamic Penetrometer: They content a list of the penetration of the cone (centimeter) measured after each blow, for a total of 32 points.
4. Granulometric analyses: They content a list with the result of the complete granulometric analyses.
