To prolong the life cycle, it is necessary to maintain a relationship between the smoothness of the pavement and its resistance. 10.1061/9780784482476.021, ASTM International (2011). The ASTM D6236-11 (ASTM International, 2011) guide states that control of the final resistance of Soil Cement (SC) must be carried out by extracting nuclei in the field after its maturation stage, and that its results must be compared with a mixture design validated in a laboratory (Emmert et al. Supplementary Cementitious Materials for Concrete: Characterization Needs. Informe sobre Suelo Cemento. The employed soil was a selected material (A-25), classified as coarse sand with low compressibility clay, which, for this work, constituted a constant in the investigation and abode by the ACI 230 procedure. To predict resilience, it was necessary to subject the three mixture designs to the same curing conditions. 36,63 After analyzing the results, a linear equation was deduced which would facilitate quality control during the construction process. 6,43 2.

Accounting process-related CO 2 emissions from global cement production under Shared Socioeconomic Pathways. After organizing and running relative difference calculation models, it was determined that, due to the increase in temperature ΔT, the most favorable curve is the product between the maximum maturity factor obtained from the temperature measurements during the first 30 hours, for which the Resilient Module (Mr-450) is graphed as a function of the product. 32,48 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 %. Additional research is recommended to validate the relationship between the degradation induced by recompaction and that generated in the materials when used as pavement structural layers. Figura 30.
