<dc:description>El reciclado de firmes in situ con cemento es la técnica de rehabilitación de carreteras más sostenible,&#xd;
al transformar el firme deteriorado en una capa nueva, aprovechando la carretera como suministro de&#xd;
áridos.&#xd;
Ante la ausencia de investigaciones, esta Tesis caracteriza el material estructuralmente y determina las&#xd;
leyes de comportamiento. Para ello, seleccionado un tramo de carretera tipo (SA-801), reciclado y&#xd;
transportado al laboratorio, se ensayó durante tres años (más de 350 roturas, muchas de ellas&#xd;
dinámicas), determinando:&#xd;
• La correlación entre resistencia a compresión controlada en obra (7 días), y resistencia a&#xd;
tracción y flexotracción a largo plazo (nunca antes medidas).&#xd;
• La caracterización a fatiga.&#xd;
Los resultados obtenidos permiten obtener modelos matemáticos de respuesta del reciclado, que con&#xd;
modelos de comportamiento, optimizan el dimensionamiento. Se realiza una propuesta de&#xd;
normalización a nivel nacional, concretando todo ello en un catálogo de secciones de firme reciclado&#xd;
in situ con cemento. ____________________________________________ On site pavement recycling with cement is the most sustainable restoration technique, by means of&#xd;
which a degraded pavement is transformed into a consistent and more homogeneous structure, using&#xd;
the road as a source of aggregates. Both bearing capacity and homogeneity are therefore considerably&#xd;
improved. Due to the absence of research information, this Thesis characterizes the structural recycled material&#xd;
and determines its laws of behavior. To do this, the SA-801 road was selected and recycled. The&#xd;
material was transported to the laboratory and underwent testing over a period of three years (more&#xd;
than 350 strength tests, many of these have dynamic variables) in order to obtain the following:&#xd;
• Correlations between compressive strength at 7 days intervals, which is the usual control&#xd;
parameter at the work site, and long-term tensile and flexural strength (not tested previously).&#xd;
• Fatigue characterization of recycled materials with cement.&#xd;
These results have been used to develop performance models, optimizing the structural design of&#xd;
pavements with cement-recycled layers. Using performance and behavior models, a catalog of&#xd;
structural sections has been proposed and could be implemented in the near future.</dc:description>
