<mods:abstract>In the construction of land transport infrastructures such as roads, highways, or railways,&#xd;
one of the factors that determine their design most is the characteristics of the terrain&#xd;
through which they run. Additionally, tunnels have become one of the most adopted&#xd;
solutions to reduce environmental impact. The characteristics of the rock mass are a key&#xd;
point to decide the layout of the tunnel and its construction method. However, the rock&#xd;
masses are discontinuous, anisotropic, and heterogeneous media, so their classification and&#xd;
knowledge are needed for a safer design of these infrastructures.&#xd;
The rock mass is not an industrial material with “pre-established” properties and&#xd;
behaviours, but rather a natural material that needs to be analyzed, understood, and&#xd;
standardized. The need to understand the behaviour of the rock mass has led throughout&#xd;
modern history to the use of different standards, which lead to the development of&#xd;
geomechanical classifications, with the aim of establishing a common language that&#xd;
translates the very advanced geological language in the macro and microgeological&#xd;
behaviour, which is needed for applications in civil engineering. In the last decades of the&#xd;
20th century, and in the present 21st, the efforts in the process of understanding the intact&#xd;
rock and the rock mass has been constantly increasing because a better understanding of&#xd;
the rock mass behaviour implies a better result in reached in projects involving affection to&#xd;
rock masses. This paper briefly reviews the history of rock mass classifications, their&#xd;
implications in rock mechanics and their applicability in the definition of behaviours as a&#xd;
function of natural conditions and human action, as well as their direct implication in some&#xd;
fields of the transport infrastructures management with regard to hazard and risk&#xd;
assessment.</mods:abstract>
