El objetivo de la presente investigación fue el desarrollo de una mezcla fría con sustitución del relleno mineral por rellenos cementantes ternarios que en conjunto forman productos de hidratación y brindan mayor resistencia en presencia de agua. Los rellenos cementantes ternarios están compuestos por escoria de alto horno granulada (EGAH), ceniza volante (CV) y un activador alcalino, ya sea cemento Portland (CP) o hidróxido de calcio (cal). A fin de comparar cuál de estos activadores brinda un mayor desempeño se prepararon distintas mezclas con sustitución parcial y total, para evaluar en tres condiciones de curado y observar el comportamiento de las mezclas en presencia de agua. Se comprobó que la sustitución con ambos tipos de rellenos cementantes reduce significativamente los efectos de la humedad a edad temprana. Para la condición de curado de 3 días a 25 °C, la muestra de referencia obtuvo una pérdida de estabilidad de 30,78 %, las muestras con CP de 7,61 y 7,56 %, y las de cal con 13,83 y 16,39 %, por lo que se observa que tienen una menor pérdida de estabilidad en todos los casos, este mismo patrón se mantiene en el tiempo.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The use of cold asphalt mixtures has aroused interest in recent years because it is a technique that reduces the use of fuels and thus the carbon footprint in the construction and maintenance of pavements, however its use has been limited in patching applications and low-traffic pavements, however, these mixtures have low resistance at an early age and high amounts of voids. The objective of this research was the development of a cold mixture with replacement of the mineral filler with ternary cementitious fillers that together form hydration products and provide greater resistance in the presence of water. The ternary cementitious fillers are composed of granulated blast furnace slag (EGAH), fly ash (CV) and an alkaline activator, Portland cement (CP) or calcium hydroxide (lime), in order to compare which of these activators provides greater performance different mixtures were prepared with partial and total substitution, to evaluate in three curing conditions and observe the behavior of the mixtures in the presence of water. It was proven that replacement with both types of cementitious fillers significantly reduces the effects of moisture at an early age. For the curing condition of 3 days at 25 °C, the reference sample obtained a loss of stability of 30,78 %, the samples with CP of 7,61 and 7,56 %, and those of lime with 13,83 and 16,39 %, have a lower loss of stability in all cases, this same pattern is maintained over time.]]></p></abstract>
