Efecto del taladrado para la extracción de núcleos en la pérdida de ligante, evaluada en pavimentos asfálticos de mezclas en frío

Abstract

In the field of engineering there are hot and cold mixtures. For its correct performance, it is vital to have an adequate asphalt mix, which entails quality procedures both at the time of its design and its placement. With respect to cold asphalt mixes, these have the advantage that they do not require the use of energy to heat them, since they use asphalt emulsions, which facilitate their placement and compaction in hot, temperate and cold climates. The cold mix asphalt was made with asphalt emulsion and aggregates from the Pifo quarry. When using this mixture, two processes were carried out, the manufacture of compact briquettes manually and the extraction of nuclei. With the objective of identifying through a comparative and experimental study the loss of asphalt binder between the manually compacted briquettes and the extraction of cores. Which were extracted from a wearing course in service in order to determine the degree of correlation of the essential parameters to determine the percentage of asphalt used both in the laboratory and on site. It is determined that the behavior of the mixtures obtained by both compaction and nuclei have a similar performance and that the technique for obtaining nuclei does not influence the loss of asphalt, having used refrigerant for the extraction of samples.
