“…This effect is clearly observed regardless of the size of the specimen, which is the variable that least affects the measurements made. This conclusion is in accordance with other studies that also show that the different dimensions of the specimens did not affect the modal test results in cylindrical geometries unless they had a thickness of less than 4 centimeters (16,17,18,19). Nonetheless, it should be pointed out that for the mixtures tested and the temperature used here, the obtained values have high repeatability, suggesting that the resonance impact test is suitable for assessing changes in the modulus of bituminous mixtures.…”

“…The values of modulus obtained vary between the different methods, since the non-destructive test applies frequencies that are considerably higher than those used in the laboratory tests, and these tests are therefore not comparable. This is something characteristic of the test, which occurs systematically, particularly at higher temperatures, as found in several studies (15,16,19). Thus, higher values are obtained when determining the modulus with the impact resonance test (it should be pointed out that the values obtained from different laboratory methods are also not comparable, since they apply different types of efforts and frequencies).…”

“…Such studies aimed to improve the estimation of damping properties (16,17), or apply the tests to different geometries such as thin disk specimens (18). In some cases, work was aimed at exploring the possibility of estimating the damage in asphalt mixes (17,19).…”

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.

“…Cylindrical shaped asphalt concrete and cement concrete specimens with 100 mm diameter and 20 mm thickness are used in this study. The geometry of the specimens was decided based on the general recommendation of length to nominal maximum aggregate size ratio of 1.5 [18].The cement concrete sample is only used for additional verification of the experimental test set-up, since it is not as sensitive to temperature changes. The asphalt concrete specimen has a nominal aggregate size of 11 mm.…”

This paper studies the applicability of an automated non-destructive testing method to monitor the stiffness of asphalt concrete at low temperatures. A loudspeaker is used as a source of non-contact excitation of the axially symmetric fundamental resonant frequencies of a disc-shaped asphalt concrete specimen positioned inside an environmental chamber. Measured resonant frequencies are used to calculate the dynamic moduli of the specimen at different temperatures. The repeatability of the method as well as the effect of loudspeaker height above the sample are studied. Results show that the main advantage of the non-contact excitation method, compared to manually applied impact hammer excitation, is that repeatable automated measurements can be performed while the specimen is placed inside an environmental temperature chamber. This methodology enables to study the effect of only low temperature conditioning on the dynamic modulus of asphalt concrete without interference from mechanical loading.

“…CR has been widely used in concrete to provide F-T protection [32]. Meanwhile, Zhang et al [33] found that rubber modified asphalt mixture has better antifreezing performance than the neat one. Current research results indicate that CR is an effective additive to improve the F-T resistance for road materials.…”

Asphalt mixture is susceptible to moisture damage under the effect of freeze-thaw (F-T) cycles. In this paper, crumb rubber (CR) was used to modify stone mastic asphalt (SMA) and the effects of diatomite and styrene butadiene styrene (SBS) on antifreezing performances of crumb rubber modified SMA (CRSMA) were investigated. Regression analysis and modified grey model (MGM) were used to construct the prediction models for properties of modified mixtures. CRSMA, CR and diatomite modified SMA (CRDSMA), and CR and SBS modified SMA (CRSSMA) were prepared in laboratory, respectively. Process of F-T cycles was designed. Air void, indirect tensile strength (ITS), and indirect tensile stiffness modulus (ITSM) were measured to evaluate the antifreezing performances of CRSMA, CRDSMA, and CRSSMA. Results indicate that air voids increase with the increasing of F-T cycles. ITS and ITSM all decrease with the increasing of F-T cycles. The addition of diatomite and SBS can reduce the air void and improve the ITS and ITSM of CRSMA. CRSSMA presents the lowest air void, highest tensile strength, and largest stiffness modulus, which reveals that CRSSMA has the best F-T resistance among three different kinds of mixtures. Moreover, MGM (1, 2) models present more favorable accuracy in prediction of air void and ITS compared with regression ones.
