Analysis of the Resilient Modulus and California Bearing Ratio in mixtures containing slate waste and clayey soil

The use of slate waste can help to reduce the impacts caused environment due decrease appropriate disposal areas and disordered consumption raw material. This article presents an analysis Resilient Modulus (RM) California Bearing Ratio (CBR) this in mixtures with clayey soil. To analyze variations RM CBR increase content, tests were carried out on reference (REF) containing (SLT). for granular material (gneiss REF SLT) clay soil, different levels materials (50%, 60%, 70%, 80% 90%) It was observed that values SLT increased 62.8% 127.0% addition between 50/50 90/10 mixtures, respectively. behavior similar presented by which 125.0% 60.1% same results obtained indicate those conventional (such as mixtures) used layers sub-base base pavements. Finally, it concluded relationship is non-linear both (REF function addition.
