This Experimental work, aims to correlations development between CBR Laboratory tested. (California Bearing Ratio) and Soil’s Mechanical and Properties Index from “Pasa” and “San Fernando” (parishes closer to Ambato City). I have taken 12 samples: 6 from each parish located in 3 different roads choose by the investigator, every sample have enoguh amount of material for testing procedures in the Lab. Once completed, we obtained the Analysis Results for its interpretation allowing to determinate Soil Types and its characteristics. In the Determination process for correlations between two rates, we applied Analysis by Regression, and for the correlation between three different rates we used the Minimun Squared Method (MCO) so The Correlation is aceptable if its Coefficient Determination is higher than 50 percent. As a result we obtained 27 correlations with a Coefficient Determination ranges between 50 percent – 96.13 percent this results subsecuently allowed us to obtain the CBR quite close to the Laboratory Tested CBR Results. So the Required Flexible Pavement Design Thickness in each Capes are the same ones.
