A concepção de infra-estruturas lineares e particularmente de estradas em regiões tropicais e subtropicais continua a basear-se principalmente em métodos empíricos. A tendência actual na concepção de pavimentos é de utilizar parâmetros derivados directamente de testes laboratoriais ou in-situ. Neste estudo, são apresentadas duas abordagens para a concepção de estruturas de pavimento. Em primeiro lugar, uma estrutura de pavimento rodoviário constituída por solo laterítico tratado com cimento é concebida utilizando o método empírico americano do AASHTO e o método mecanicista-empírico francês do LCPC-SETRA, implementado no código de concepção Alizé1.3. Em segundo lugar, os resultados obtidos por estes dois métodos são comparados com os já obtidos e fornecidos no Guia CEBTP de concepção de pavimentos para países tropicais. As relações de regressão são propostas com base nos parâmetros-chave utilizados na concepção de pavimentos. São robustos e produzem boas correlações lineares.
