Highlights
This study shows the improvement of laterite from Benin whose borrowing is abandoned with class 0/31.5 granite crushed stone for its use in road construction according to the rules of CEBTP of 1972, revised in 1984
The results of the mixes 35% crushed + 65% laterite and 40% crushed + 65% laterite meet the criteria of CEBTP, 1984 for the foundation layer of flexible pavements
We carried out the direct shear test on natural laterite and the two mixtures used as a foundation layer for flexible pavements in order to identify the best mix
