“…However, the difference in air void content between the specimens produced with the Marshall hammer and the gyratory compactor is around 1%, while the ITSR values range from 63% to 93%. Further investigation is needed to confirm that the kneading effect, apart from improving the efficiency of densification (and preventing the entrance of water) is able to enhance the binderaggregates adhesiveness, as suggested in previous investigations [25,26].…”

“…According to Vega-Zamanillo et al [25], when studying dense-graded mixtures with WMA additives and without a rubber modifier, the ITSR values were better when the specimens were compacted with the gyratory compactor. Jiang et al [26] also found that the Marshall compactor can lead to mechanical properties 20% lower than those of compacted specimens, up to the same density, with a vertical vibration plate. Several studies that have compared laboratory compaction procedures with real-scale compaction [27][28][29] have concluded that the gyratory compactor may represent field compaction better than other laboratory compactors.…”

Evaluation of Warm Rubberized Stone Mastic Asphalt Mixtures through the Marshall and Gyratory Compactors

Stone mastic asphalt (SMA) mixtures exhibit excellent behaviour; they are highly resistant to reflective cracking and permanent deformation, as well as providing the wearing surface with an optimal texture. However, the production and compaction temperatures are similar to conventional mixtures, which means that there is a significant consumption of energy, as well as greenhouse gas emissions. Warm mix asphalt (WMA) technology, which has been developed over the last few years, might allow lower temperatures without compromising the mechanical behaviour of the mixtures. Also, over the last few decades, rubberized asphalt has proved to be effective in improving the performance and being environmentally suitable, but it requires higher production temperatures than conventional mixtures. In this study, several tests were performed to evaluate the effect of a chemical WMA additive on the compactability and water sensitivity of rubberized SMA mixtures with both the Marshall and the gyratory compactor. The investigation has shown that the gyratory compactor is more suitable for studying compactability and the water sensitivity of rubberized SMA with WMA additives.

“…Road workers in France, Switzerland and other countries have studied the effect of vibration molding by subjecting test specimens to lateral vibrations under a vertical load [16]. Thus far, VVTM has proven successful in designing road surface materials such as dense-graded asphalt mixtures and recycled emulsified asphalt mixtures [17][18][19][20][21], and road base materials such as cement stabilized macadam [22][23][24][25]. All of these materials achieve high road performance.…”

In this study, stone mastic asphalt (SMA-13) mixtures were designed using three methods, namely the vertical-vibration testing method (VVTM), Marshall method, and superpave gyratory compactor method (SGC). The performances of SMA-13 designed by all three methods were measured and compared. Results show that the optimal asphalt content of the asphalt mixture was 5% lower in the VVTM-designed SMA-13 than in the Marshall-designed and SGC-designed asphalts mixture. In comparison with the Marshall- and SGC-designed asphalts mixture, the VVTM-designed SMA-13 exhibited higher density (2.4% and 2.2% increase, respectively), mechanical properties (32% and 13% increase, respectively), high-temperature rut resistance (30% and 8% increase, respectively), low-temperature crack resistance (20% and 17% increase, respectively), water stability (4% and 3% increase, respectively), and fatigue life (at least 33% and 9% increase, respectively). The VVTM-designed SMA-13 exhibited a deeper short-term aging degree than the other SMA-13 specimens, but a smaller long-term aging degree. In summary, the SMA-13 mixture designed by the VVTM method delivered a better road performance and durability than the traditional design method, enabling improved designs of SMA mixtures.

“…The vertical vibration testing method (VVTM) displays good simulation of the working state of the vibration roller, and vertical vibration testing equipment (VVTE) is economical [20,23]. VVTM has been successfully applied to several road materials in some studies, such as asphalt mixtures [24][25][26], RAP treated with cement or emulsified asphalt [27,28], and crushed rock stabilized with inorganic or organic binders [29][30][31]. The mixture samples molded by VVTM exhibits good mechanical and fatigue properties.…”

This paper focuses on investigating the fatigue properties of cold-recycled emulsified asphalt mixtures (CEAMs) designed via two different compaction methods. First, two different CEAM compaction procedures were investigated and evaluated, including the modified Marshall compaction method (MMCM) and the vertical vibration testing method (VVTM). Indirect tensile fatigue tests were then performed to research the fatigue lives of CEAMs fabricated via the two methods. Finally, a Weibull distribution was applied to analyze the fatigue test results, and the fatigue equation was constructed. The results indicated that the average mechanical strength ratio between the CEAM samples produced by VVTM and the field core samples was >92%, whereas the average ratio of the specimens shaped by the MMCM was <65%. Compared with MMCM-molded CEAMs, VVTM-fabricated CEAMs showed decreased optimal moisture and emulsified asphalt contents by 11% and 9%, respectively, but exhibited improved moisture stability, anti-cracking performance, and anti-rutting performance by 4%, 12%, and 35%, respectively. The fatigue equations established on the basis of the Weibull distribution could effectively assess the fatigue life of CEAMs. The VVTM-manufactured CEAMs showed good resistance of stress change sensitivity and fatigue failure under different stress ratios. The VVTM-compacted CEAMs demonstrated increased fatigue life by 36% at a stress ratio of 0.45 and by 325% at a repeated load of 0.27 MPa compared with the MMCM-fabricated CEAMs.
