“…The influence of the size of particles, temperature, and density of the mix-asphalt material was analyzed under the excitation of tampers [7,10,11]. The Fuzzy technique, compaction monitoring system, and multi-sensor infrared temperature scanning bar system were also applied to reduce the error of the unequal converge and optimize the compression density of the mix-asphalt material, respectively [8,12,13]. The research results indicated that the maximum compression performance could be achieved by using hot mix-asphalt under high and stable amplitude compressive forces of tampers.…”

To enhance the compression performance and improve the paving quality of the VSS of the pavers, the experimental research of the VSS is performed to assess the VSS's vibration stability under various excitations of the tampers and vibrator screed. A VSS's dynamic model is also established to simulate and evaluate the VSS's working performance. The root-mean-square (RMS) acceleration responses of the vertical and pitching motions at centre of gravity of the screed floor are chosen as the objective functions. In order to increase the VSS's working performance, the dynamic parameters of the angular deviations of tampers are then controlled based on Fuzzy control. The research results indicate that the RMS value of the vertical screed motion is remarkably increased, concurrently the RMS value of the pitching screed angle is significantly reduced by controlling the angular deviations of tampers under different excitation frequencies of the VSS. Therefore, the VSS's working performance is significantly improved in comparison without the control of the angular deviations.

“…Based on the input-numerical signals of the excitation frequency f t and screed shacking accelerations a φ and a θ , the compression efficiency, paving quality, and working stability of the AP are clearly improved by controlling the angular deviations of α and γ under different working conditions. Especially, based on the databases of the compaction monitoring system using the global positioning system technologies, 16 the fuzzy clustering techniques apply to quickly analyze the hot mix asphalt compaction data, 10 or the multi-sensor infrared temperature scanning bar system used to analyze the paving quality, 17 the paving performance of the AP can be further improved by controlling the vibration of the VSS based on these databases.…”

To reduce shaking of a vibration screed system (VSS) and improve the paving performance of an asphalt paver (AP), the root-mean-square (RMS) acceleration responses at points on the front and rear screed floors are analyzed via an experimental method. A 3D nonlinear dynamic model of the VSS is also built to evaluate the influence of the dynamic parameters of the VSS on the compression efficiency, paving quality, and working stability of the AP based on the objective functions of the vertical, pitching, and rolling RMS values at the centre of gravity of the screed. The angular deviations, $alpha$ and $gamma$, of the tamper are then controlled to improve the paving performance. The research results show that the excitation frequency, $f_{t}$, and both angular deviations, $alpha$ and $gamma$, of the tamper strongly affect the paving performance. The compression efficiency is quickly enhanced, while both paving quality and working stability are significantly reduced with increasing the excitation frequency $f_{t}$ and reducing the angular deviations. $alpha$ and $gamma$. and vice versa. Additionally, the screed shaking and paving performance of the AP are remarkably improved by control of the angular deviations, $alpha$ and $gamma$, under different working conditions.

“…Carbon emissions of these compaction methods are different and need proper assessment to meet the growing concerns and regulations to minimise the carbon footprint [ 7 ]. Thus, the optimisation of the field rollers’ movements has been addressed by the monitoring with Global Positioning Systems (GPS), which has contributed to the homogeneity of the density and the pavement’s mechanical properties [ 8 ]. Both in the laboratory and the field, controls are necessary to verify material void contents.…”

Influence of the Compaction Method in the Volumetric Design of Cold Recycled Mixtures with Emulsion

et al. 2021

Compaction of cold asphalt mixtures is a subject that has not been thoroughly studied, and, for this reason, requires new efforts from researchers to have a better understanding. Unlike hot mixtures, cold mixtures and mainly recycled mixtures require specific considerations for compaction. There is a lack of consensus about the methodology to select the optimum premix water and emulsion contents. In the absence of specific regulations, the use of soil tests or hot mixtures procedures is common. For these reasons, this investigation’s main goal was to evaluate two compaction methods used to design cold recycled mixtures with emulsion: the modified Proctor procedure and the gyratory compaction. It was concluded that both methods could be useful to study compactability since consistent results were obtained by applying the maximum bulk density criterion. However, the higher bulk densities achieved, the smaller specimens used, and the suitability of the gyratory specimens to be later tested for mechanical properties make them preferable to the modified Proctor samples. A new approach has been proposed using iso-density lines on dual-axis premix water content-emulsion content graphs that facilitates the study of the influence on compactability of these two factors combined. These contributions can alleviate the laboratory works during the design of cold recycled asphalt mixtures and contribute to a more in-depth knowledge of the combined effect of premix water and emulsion contents on the compactability of cold recycled mixtures with emulsion.
