Table 4: Results of geotechnical analyses of the samples studied. According to the results (Table 4), it is noted that the samples of carbonate rocks (limestone and dolomite) have a density between 2.6 t/m\({}^{3}\) and 2.74 t/m\({}^{3}\), with porosity and absorption that do not exceed 3.5% and 1%, respectively. These types of rocks show highly variable wear resistance (MDE) and impact resistance (L.A) values and do not exceed 30% for MDE and 35% for L.A.  
For the samples of the magmatic rocks (granite, basalt, diorie, granodiorite, inimphrite, and rhyolite), the results show that the density varies between 2.58 t/m\({}^{3}\) and 2.8 t/m\({}^{3}\), the porosity is between 0.3% and 3.1% and the absorption of 0.12% and 1.2%. In addition, they have a wear resistance (MDE) and impact resistance (L.A) that does not exceed 17% for MDE and 20% for L.A, except for the sample SC-33, which has a value of about 30%. The detritic and volcano-detritic rock samples (breccia and tuff, conglomerate, sandstone) have a density between 2.5 t/m\({}^{3}\) and 2.69 t/m\({}^{3}\), a porosity between 0.33% and 1.1%, and an absorption range between 0.15% and 0.8%, except for the SC-18 sample, which is a conglomerate; the results show wear resistance (MDE) values ranging from 12% to 23% and impact resistance (L.A) from 15% to 25%. From these results, it can be deduced that these rocky materials show very good physical characteristics with very high densities that vary between 2.5 t/m\({}^{3}\) and 2.8 t/m\({}^{3}\), low porosity that does not exceed 3.5%, and absorption of less than 1%. On the other hand, the lower the Los Angeles (L.A) coefficient and the micro-Deval coefficient (MDE), the more it means that the rock material is excellent in terms of impact resistance and wear resistance [47]. According to the results, we can see that almost all the samples have good to very good mechanical characteristics with values of L.A between 12% and 35% and MDE between 5% and 30%.
