This work discusses an experimental study that aims to evaluate the influence of lime on the mechanical properties ( Compression, Expansion and ISC ) , to compose roadworks ( urban pavements ) in the municipality of Barra do Bugres , Mato Grosso . The experiments performed in the laboratory wrapped chemical and mineralogical characterization , physics ( liquid limit , plastic limit and particle size analysis) , and mechanical ( ISC and expansion ) of the soil in its natural state and the soil-lime mixtures . The soil-lime mixtures were tested at doses of 2 % , 4 % and 6 % ( 2g , 4g and 6g of lime per 100g soil) . The bodies of the proof - of - mixtures , molded at optimum moisture natural soil underwent curing time of 7 days in flooded condition of four (4 ) days , to then be broken and thus obtain values of ISC and expansion under these conditions . The results show that there was an increase in the ISCmédio of all samples stabilized with lime, and also, with the reduction of soil expansion.
