Each mix design has a compressive strength of 4,5 MPa at 7 days of age and durability measured with the 10% wetting and drying test. The method consisted of curing the samples of the three mix designs at three different temperatures -11, 30, and 40 °C- and then monitoring the development of the temperature within the samples during the first thirty hours. At 28 days of age, the resistance modulus of the samples was measured with cyclic triaxial equipment. After analyzing the results, a linear equation was deduced which would facilitate quality control during the construction process. This prevents microcracking of the compacted layers, since their fracturing is not necessary during the extraction of nuclei and field density tests.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN Esta investigación correlaciona la temperatura de fraguado del Suelo Cemento (SC) con su módulo resiliente, a partír del índice de madurez de tres mezclas fabricadas con diferentes tipos de cementos: uso general, Altas Resistencias Tempranas y Moderado calor de Hidratación. Cada diseño de mezcla cuenta con una resistencia a la compresión de 4,5 MPa a los 7 días de edad y una durabilidad medida con la prueba de humedecimiento y secado del 10%. El método consistió en curar las muestras de los tres diseños de mezcla en tres temperaturas diferentes -11, 30 y 40 °C- para luego monitorear el desarrollo de la temperatura al interior de las muestras durante las primeras treinta horas. A los 28 días de edad, se midió el módulo resiliente de las muestras con equipo triaxial cíclico. Tras analizar los resultados, se dedujo una ecuación lineal que facilitaría un control de calidad durante el proceso constructivo. Esto evita la micro fisuración de las capas compactadas, ya que no es necesario fracturarlas durante la extracción de núcleos y las pruebas de densidad en campo.]]></p></abstract>
