The technique of paving low-volume roads with roller-compacted concrete (RCC) has been
used for 17 years in northeastern Spain. The construction costs of this technique are
economically favorable when compared to other structurally equivalent alternatives.
Maintenance costs are also lower and the pavement is highly durable because the strength
of roller-compacted concrete is similar to that of a conventional vibrated concrete. These are

The technique of paving low-volume roads with roller-compacted concrete (RCC) has been used for 17 years in northeastern Spain. The construction costs of this technique are economically favorable when compared to other structurally equivalent alternatives. Maintenance costs are also lower and the pavement is highly durable because the strength of roller-compacted concrete is similar to that of a conventional vibrated concrete. These are some of the reasons that justify its use. The advantages of the use of concrete as a paving material can be summarized as follows: conventional machinery can be used that is not specific to concrete; the newly paved surface can usually be traveled on immediately; and the materials are very economical because binders with a high fly ash content can be used. About 4 million sq m of low-volume roads have been paved using this technology. An experimental study was undertaken in which tests were performed on core samples to check the performance of these RCC pavements during their years of service. The result is a detailed file on the performance and current condition of many of them.
