The California Bearing Ratio (CBR) is a method for the relative quality of the subgrade, subbase and base of a pavement evaluation throughout an essay on the field or laboratory and also pavement design. The most common is CBR soaked, nevertheless, obtaining its value is expensive and time consuming. The main objective of this research is correlating CBR with some index properties of soils of easy evaluation: percentage of gravel (G), percentage of sand (S), percentage of fine (F), liquid limit (LL), plastic limit (PL), plastic index (PI), optimal moisture content (OMC) and maximum dry density (MDD); to propose an alternative method to obtain the CBR value. For this research, simple and multiple correlation using Microsoft Excel was applied in a total of 75 samples of granular and clayed soils from Piura city, obtained from a local laboratory's records.
