“…A higher value indicates a longer lifespan and better performance of the pavement. The pavement containing 30% hydrated lime and 70% bottom ash had the highest density, which is the recommended density for the road surface and intermediate layers with small infrastructures and light traffic [86]. However, the results of this research are contrary to the findings of an earlier study [85], which showed that using bottom ash as a filler substitute resulted in a higher rutting potential and a lower dynamic modulus than the control mixture.…”

One effective method to minimize the increasing cost in the construction industry is by using coal bottom ash waste as a substitute material. The high volume of coal bottom ash waste generated each year and the improper disposal methods have raised a grave pollution concern because of the harmful impact of the waste on the environment and human health. Recycling coal bottom ash is an effective way to reduce the problems associated with its disposal. This paper reviews the current physical and chemical and utilization of coal bottom ash as a substitute material in the construction industry. The main objective of this review is to highlight the potential of recycling bottom ash in the field of civil construction. This review encourages and promotes effective recycling of coal bottom ash and identifies the vast range of coal bottom ash applications in the construction industry.

“…In this respect, it is worth noting that bituminous mixtures have a certain damping due to their partly viscous nature, and this should be taken into account when determining the resonance frequency. Therefore, the natural frequency (f n ) that will be used in the calculation of the modulus must be calculated from the frequency obtained in the measure (f d ) [2] (13).…”

“…This is also the main reason why new elements such as polymers, crumb rubber or thermal power plant ashes (1,2) are being incorporated into bituminous mixtures, in order to achieve more durable pavements that have minimal impact on economic and social activities. In this respect, determining the degree of deterioration of the materials used in the construction of these infrastructures can be of considerable value when attempting to identify the suitability of these new components and the optimal time to conduct rehabilitation activities.…”

ABSTRACT:The modulus value of bituminous materials is a key factor in the design of road pavements and the estimation of their life service. This parameter can be measured in laboratory but, unfortunately, this requires the deterioration of the pavement so as the consumption of time and resources. Therefore, this study analyses the feasibility of using impact resonance frequency tests as an alternative to traditional methods for determining the dynamic modulus of bituminous mixtures. The sensitivity of this technique has been studied by analyzing its repeatability and reproducibility, studying the variations in the values measured by modifying the dimensions of the specimens, test temperatures and types of mixture tested. In addition, this non-destructive technique has been compared with other traditional tests used to determine the elastic properties of bituminous materials. The results show that this test could be an interesting tool to characterize the properties and damage state of asphalt layers. RESUMEN: Análisis de la sensibilidad del ensayo de resonancia por impacto como herramienta para determinar las propiedades elásticas de materiales bituminosos.El valor de módulo de los materiales bituminosos es un factor clave en el diseño de pavimentos y la estimación de su vida de servicio. Este parámetro puede ser medido en laboratorio pero, desafortunadamente, esto requiere deteriorar el pavimento así como el consumo de tiempo y recursos. Por ello, este estudio analiza la viabilidad de usar el ensayo de frecuencia de resonancia mediante impacto como alternativa a los métodos tradicionales para determinar el módulo dinámico de mezclas bituminosas. La sensibilidad de esta técnica se ha estudiado analizando su repetibilidad y reproducibilidad, estudiando variaciones en los valores medidos al modificar dimensiones de probetas, temperaturas y tipos de mezcla ensayados. Además, esta técnica no destructiva se ha comparado con otros ensayos tradicionales empleados para determinar propiedades elásticas de materiales bituminosos. Los resultados muestran este ensayo como una herramienta interesante para caracterizar las propiedades y estado de daño de las capas de asfalto.

“…Likewise, replacing the natural aggregate with alternative materials is another strategy widely used. Thus, recycled asphalt pavement (RAP) from roads [3], by-products [4,5] or construction waste [6] are some of the materials used in bituminous mixtures to replace natural aggregate, although other are also standing out, as rubber from end-of-life tires [7,8] and other polymers [9,10], which can also be used to improve the mechanical performance of the bituminous mixtures.…”

This paper studies the design and characterization of a PA mixture with 91% of EAF slag, using a commercial CRM binder. A fatty acid amide wax was added to decrease the mixture manufacturing temperature. The mechanical performance of the designed mixtures was studied with the determination of void characteristics, water sensitivity, and particle loss in dry and wet conditions. Finally, their compactability, stiffness and fatigue resistance were also analysed. The addition of the wax allowed to decrease the manufacturing temperature 15 °C. Besides, the wax increased the complex modulus of bitumen, increasing also the elastic component and decreasing the thermal susceptibility, although these modifications did not have a significant impact in the mechanical performance of the mixture.
