AB Soil–cement is an environmentally friendly road construction technique for base andsubbase materials, which allows employing soils placed in the right-of-way of the road or in thesurroundings, by improving its engineering properties. With this technique, it is possible to reducethe over-exploitation of quarries, the necessity of landfills and the pollutant gas emission due tothe reduction of aggregate fabrication and transport. The manufacturing of soil–cement is generallycontrolled by means of the Uniaxial Compressive Strength (UCS) test at seven days, according to theregulations of each country. Nonetheless, one of the properties that best defines the performance ofsoil–cement is the Flexural Strength (FS) at long term, usually at 90 days. The aim of this paper is todevelop new equations to correlate the UCS and the FS at long term and the UCS at seven days andat 90 days. Obtained results validate the proposed models and, hence, the flexural strength can bepredicted from the Uniaxial Compressive Strength at seven days, allowing, if necessary, correctingmeasures (recalculation or rejection) in early stages of the curing time to be taken.
