“…Composition to achieve the purpose of adjustable eccentricity. The boarding and getting off systems are connected by the vibration damping block, and the getting off system receives regular vibration through the restraining effect of the boarding system [29]. There are four key parameters affecting the compaction effect, namely vibration frequency, exciting force, static pressure, and compaction time.…”

“…The VCM was gradually applied to the asphalt surface in recent years for its advantages. Oliveira et al proposed a laboratory VCM that better simulates the conditions of the on-site asphalt mixture [29]. Jiang et al used the VCM and Marshall methods to design asphalt mixtures and evaluate their road performance, which indicates that the asphalt mixture laboratory prepared by VCM is better than that of the mixture prepared by Marshall method [30,31].…”

This paper presents a study of the properties of soil–rock mixtures (SRM) prepared by the vibration compaction method. First, the results of laboratory experiments and field tests are compared to determine the reasonable parameters of the vibration compaction method (VCM) for soil–rock mixtures. The compaction characteristics, CBR, and resilient modulus of the laboratory-prepared soil–rock mixtures by the static pressure compaction method (SPCM) and vibration compaction method are compared. The effects of the soil to rock ratio and the maximum particle size and gradation on the compaction characteristic, resilient modulus and CBR of soil–rock mixtures prepared by the vibration compaction method are investigated. Finally, field measurements are subsequently conducted to validate the laboratory investigations. The results show that the reasonable vibration frequency, exciting force, and static surface pressure of the vibration compactor for soil–rock mixtures are recommended as 25 Hz, 5.3 kN, and 154.0~163.2 kPa, respectively. Soil–rock mixtures prepared by vibration compaction method has smaller optimum water content and gradation variation and larger density than specimens prepared by the static pressure compaction method, and the CBR and resilient modulus are 1.46 ± 0.02 and 1.16 ± 0.03 times those of specimens prepared by the static pressure compaction method, respectively. The ratio of soil to rock, followed by the maximum particle size, lead obvious influences on the properties of soil–rock mixtures. Moreover, the results show that the CBR and resilient modulus of soil–rock mixtures prepared by vibration compaction method have a correlation of 86.9% and 89.1% with the field tests, respectively, which is higher than the static pressure compaction method.

Permanent deformation (rutting) is a common type of distress in asphalt pavements. It is widely accepted that the problem occurs due to the heavy load applications and slow movement of traffic. It is clear that permanent deformation or rutting needs to be predicted to avoid major deformation to the flexible pavement. In this study, based on using the strain-dependent properties of the asphalt mixture in a multi-layer linear viscous analysis, a technique has been developed to predict asphalt mixture rut depth. Also, three different types of asphalt mixture were selected to apply the technique at various temperatures. The material properties of asphalt mixtures were derived from the repeated load axial test and they are represented by a strain-dependent axial viscosity. The predicted outcomes were then verified by comparison with measured results obtained from the wheel tracking tests. The research results have indicated that the technique is really practical and should be considered to predict a field rut depth. Moreover, based on the use of technique, the rutting prediction results applied for all mixtures at 45oC was fairly good while they presented poorer performances at 60 oC. Finally, the study has found a quick adjusted method to achive more accurate prediction results when a mixture reaches the tertiary stage of creep.
