Tropical soil characterization techniques for pavement subsidy in brazil and colombia.

Abstract

Considering the presence of tropical soils in Colombia, mainly highlighting the Amazon and Orinoquia regions, it is imperative to carry out the evaluation of appropriate methodologies to study the physical and mechanical characteristics of this type of soil. The above, to have the basis for the design of road pavement structures. In this sense, Brazil has made significant progress in the study of tropical soils, developing the MCT (Tropical Compact Miniature Methodology). Since tropical soils are of sedimentary origin and have chemical and mineralogical properties difficult to determine using traditional methodologies of soil mechanics. The objective of this work is to describe the MTC, as well as some compaction tests and physical-mechanical properties determinations. The foregoing, to analyze the applicability of this methodology for the exploration of Colombian subsoils and specifically the characterization of subgrades for the construction of pavement structures.
