Road maintenance and rehabilitation are expected to meet modern society’s demands for
sustainable development. Full-depth reclamation with cement as a binder is closely linked to the
concept of sustainability. In addition to the environmental benefits of reusing the existing pavement as
aggregate, this practice entails significant technical and economic advantages. In Spain, in the absence
of tests specifically designed to determine the behavior of recycled pavements stabilized with cement,
these materials are treated as soil-cement or cement-bound granular material. This assumption is not
entirely accurate, because this recycled pavement contains some bituminous elements that reduce
its stiffness. This study aimed to obtain the relationships between flexural strength (FS) and the
parameters that describe the pavement behavior (long-term unconfined compressive strength (UCS)
and indirect tensile strength (ITS)) and compare the findings with the relationships between these
parameters in soil-cement and cement-bound granular materials. The results showed that the similar
behavior hypothesis is not entirely accurate for recycled pavements stabilized with cement, because
they have lower strength values—although, this is not necessarily an indication of poorer performance.
