Abstract ：
Cement stabilized crushed stone base material is widely used in pavement structures, but it is prone to damage under complex loads and freeze-thaw cycles, which can lead to pavement failure. Due to insufficient consideration of the behavior of the material under the coupling conditions of freeze-thaw and dynamic loads in engineering, there are deficiencies in the assessment of its freeze-thaw damage mechanism and fatigue life. Based on this, this article constructs a fully controlled load freeze-thaw test system suitable for simulating structures of cement stabilized crushed stone base, and based on this test system, the mechanical response of small-sized pavement structures under load freeze-thaw action is measured. The results indicate that compared to a single load, freeze-thaw cycles and load coupling accelerate the deterioration of pavement structures and produce greater deformation in the crushed stone base. Finally, the load freeze-thaw damage factor was constructed and introduced into the fatigue equation. The life prediction equation for freeze-thaw damage of cement stabilized crushed stone base structure was derived and established, providing a theoretical basis for guiding the engineering application of cement stabilized crushed stone base materials in cold regions.

Abstract ：
The aims of this study is to prospectively study the aging evolution of CRMA from the perspective of a multi-phase composite system. In this study, the multi-phase separation of CRMA was carried out by physical filtration and chemical extraction, and the multi-phase aging evolution of CRMA was investigated. The results showed a general increase in the density of the remaining sub-phases of CRMA during aging, except the liquid asphalt binder phase (LABP). The volume of the adsorbed asphalt binder phase (AABP) increased by 17.91% after TFOT aging and decreased after PAV aging, reflecting the demonstrating a change in the multi-phase structure of CRMA. The complex shear modulus of each phase of CRMA increased after aging, but the amplitude of the change was smaller than that of 70# asphalt binder. Adsorbed phase (AP) and AABP inhibited the susceptibility of CRMA high and low temperature properties to aging, respectively. The adsorption protection provided by crumb rubber inhibited the volatilisation and oxidation of the aromatics within the adsorbed asphalt binder phase. Both CRMA and its sub-phases contain polymer phases. Polymer dispersion was more evenly in AABP, and polymer agglomeration was present in AP. The swelling effect caused the polymer to disperse more unevenly.

Abstract ：
The primary objective of this paper is to select a suitable index to characterise the change law of asphalt binder fatigue performance. Four asphalt binders were subjected to RTFOT and PAV. Frequency sweep (FS) test, Linear Amplitude Sweep (LAS) test, Pure Linear Amplitude Sweep (PLAS) test were performed on aged asphalt binder to obtain Glower-Rowe (G-R) parameter, fatigue life (N-f), fatigue resistance energy index (FREI). For the LAS test, three methods (Dissipated Energy(G*sin delta), Complex Modulus (G*), Pseudo Strain Energy (PSE)) and four failure criteria (35% G*sin delta (initial), Peak Stress (Strain), Peak Stress (Pseudo-Strain), Max Storage PSE) were used to obtain the Nf. The results showed that the G-R parameter is more sensitive to aging. At high strain levels (>20%), the Nf obtained based on the 35% G*sin delta (initial )decreased with increasing aging time, while the Nf obtained based on the rest of the failure criteria showed fluctuations. The FREI of the four asphalt binders showed the multi-stage linear decrease with increasing aging time and the decrease rate of each stage was significantly different, which was similar to the cracking path of conventional materials and is favourable for determining the location of the inflection points.

Abstract ：
The use of antioxidants in asphalt binder is significant in prolonging the service life of asphalt pavements. In order to improve the aging resistance of asphalt binder, an antioxidant was mixed into SBS modified asphalt binder in this study. The effects of the antioxidant on the properties and aging resistance of SBS modified asphalt binder were characterised based on rheological parameters, chemical composition and morphology. The results showed that the aging resistance index quantitatively evaluated the aging resistance of different asphalt binders. The average aging resistance index of asphalt binder with 3% antioxidant based on different properties index was about 3.5, which meant it can prolong the aging life by approximately 3.5 times. The control of carbonyl and sulfoxide formation by antioxidant was the key driver to inhibit the macroscopic property degradation of asphalt binder. However, the antioxidant did not effectively inhibit the degradation of SBS modifiers during aging.

Abstract ：
During the aging and rejuvenation process of asphalt binder, the proportion of the catana phase in the bee structure on its appearance will change, and the influence of this change on the mechanical performances of the asphalt binder needs to be further investigated. Therefore, a two-dimensional finite element model of the bee structure is constructed on account of the processed AFM images of asphalt binder. The stress and strain distribution law about asphalt binder microstructure was investigated by comparing and analyzing the results of simulation calculations. The results of the study show that the stress in the catana phase of asphalt binder appearance is significantly larger than that in the peri phase, the internal stress in the para phase is the lowest. The catana phase exhibits the least tensile strain due to the fact that it has the largest modulus of elasticity, whereas the tensile strain within the asphalt binder is mainly concentrated in the para phase.

Abstract ：
A dual-phase change material (DPCM) containing polyethylene glycol (PEG) 400/expanded graphite (EG) and PEG1500/EG with both high and low-temperature regulation capacities was prepared. It was added as an additive to the NovaChip-Type C asphalt mixtures. Laboratory and field temperature regulation tests were designed. The images taken by SEM showed that PEG was fully adsorbed by EG and the structure of DPCM was stable. The test results showed the DPCM has good durability in the cyclic phase change process. The modified asphalt binders with different DPCM content showed different heat storage capacity. The results of temperature regulation tests showed that the addition of DPCM effectively reduced the temperature change rate of asphalt mixtures. With 1.88% DPCM, the extremum of high temperature of asphalt mixtures reduced by 2.3 degrees C while the extremum of low temperature increased by 2.0 degrees C. In terms of road performance, the cracking resistance at low temperature of asphalt mixtures gradually improved with the increase of DPCM content. Meanwhile, the rutting resistance at high temperature and water damage resistance still met the requirements of the specification. The DPCM had a good effect on restraining the occurrence of road diseases caused by temperature and prolonging the service life of the road.

Abstract ：
A composite anti-aging rejuvenator for road asphalt was studied and prepared. Asphalt samples with different aging degrees and modifier dosages were prepared by RTFOT(rolling thin film oven) and PAV(pressure aging vessle), and the viscoelastic, high temperature, low temperature and fatigue properties of the modified asphalt were comprehensively characterised based on their rheological properties. The test results showed that the composite anti-aging rejuvenator improved the fatigue performance and low temperature performance of aging asphalt. Among them, the creep rate m value at - 18 degrees C was recovered to 99.2 % of the unaged level, and the G-R (Glover-Rowe) parameter was reduced to more than 90 %. After long term aging of the composite anti-aging reclaimed mixtures were still able to maintain the water stability and low temperature performance higher than the level required by the specification. The paper found the better effect of adding same ratio of rejuvenator and anti-aging agent to aging asphalt. The reason was that the same ratio of rejuvenator and anti-aging agent could have synergistic effect and enhance each other. This paper verified the road value of the composite antiaging rejuvenator from asphalt and asphalt mixtures, which provides technical support and reference for the promotion of old pavement reclamation and long-life pavement.

Abstract ：
During the construction and maintenance of asphalt pavement, a lot of non-renewable resources are consumed, which discharge a variety of waste gasses and smoke, causing a serious impact on the environment. Reducing society's reliance on non-renewable resources is therefore key to improving sustainability. It is found that phase change materials (PCMs), as environmentally friendly materials, can spontaneously store and release heat energy by changing the phase state, thus reducing the adverse effect of temperature on asphalt pavement, reducing the occurrence of high-temperature stress, minimizing the cost of road construction and maintenance, and saving resources. In order to promote the application of PCMs in asphalt pavement, to promote self-controlling temperature technology for asphalt pavement, and to improve the sustainable development of asphalt pavement, this paper reviews the research status of PCMs in asphalt pavement, both domestically and abroad. The results show that the thermal conductivity of the modified asphalt binder can reach 0.29-0.39 W/mK, and the thermal diffusivity can reach 0.2-0.3 mm2/s, but the influence on the viscosity of the asphalt is limited, and both are less than 2000CP. The durability and thermal stability of the modified asphalt mixture are improved, and the maximum temperature can be lowered by 9 degrees C, which effectively reduces the occurrence of hightemperature stress. This review will help to better understand the function of PCMs and promote the sustainable development of green and environmentally friendly asphalt pavement.

Abstract ：
Recently, there have been many studies on the inhibition of asphalt fumes; however, the study on the inhibition of component of asphalt fumes is still limited. In this paper, four kinds of fumes and odor suppressant were selected based on the principles of physical adsorption and chemical inhibition, and the particulate matter of asphalt fumes was taken as the object of fume suppression, and the benzene organic matter among volatile organic compounds was taken as the object of odor purification. The inhibition effects of fumes and odor suppressant on asphalt fumes particulate matter and volatile organic compounds were investigated based on the gravimetric method and gas chromatography-mass spectrometry. The effects of fumes and odor inhibitors on rheological properties were obtained by dynamic shear rheometry. Results showed that asphalt fumes particles and benzene organics in volatile organic compounds were used as fumes suppression and odor purification targets, respectively. Activated carbon was the most effective in suppressing fumes with 65.7 %. It was 1.2 times more effective than diatomaceous earth and Odor Cleaner A. Odor cleaner B had the highest suppression rate of 76.4% on the benzene component of volatile organic compounds released from asphalt binder. Activated carbon also had a good suppression effect on the benzene component of volatile organic compounds released from asphalt binder, with suppression rate of 59 %. Fumes and odor suppressants had a low impact on asphalt pavement performance, especially suppressants based on chemical inhibition principles.

Abstract ：
Adding rejuvenator is a feasible method to restore the properties of aged asphalt. Due to the complex rejuve-nation mechanism between different rejuvenators and aged asphalt, there is no unified standard to evaluate the rejuvenation effect of rejuvenator. Most of the current research on rejuvenator focus on the characterization of macro mechanical properties of rejuvenated asphalt binder. In order to explore the changes of chemical composition and micromechanical properties of asphalt during aging and rejuvenation, fifteen kinds of virgin asphalt samples at different aging and rejuvenation stages were prepared. A commercial rejuvenator, aromatic oil and warm mix agent were selected as rejuvenators. The fifteen asphalt samples involved various aging methods, including water-ultraviolet aging, water free ultraviolet aging, RTFOT and PAV. Through gel perme-ation chromatography (GPC), Fourier transform infrared spectrometer (FTIR) and atomic force microscope (AFM) test, the reversibility evaluation index Rw, RC=O, RS=O and RDMT were proposed. These indexes could be used to quantitatively evaluate the rejuvenation effects of rejuvenator on the specific properties of aged asphalt. Based on the linear fitting results among various indexes, micro reversibility index of virgin asphalt (IRIV) was proposed. The results showed that the commercial rejuvenator and warm mix agent had a limited effect on the recovery of chemical composition and molecular weight of aged asphalt. The commercial rejuvenator over restored the micro mechanical properties of aged asphalt. The effect of aromatic oil on micro mechanical properties of aged asphalt was between commercial rejuvenator and warm mix agent. This study provides a way to quantitatively evaluate the rejuvenation effect of rejuvenator on virgin asphalt binder. It is helpful to better understand the aging-rejuvenation process of virgin asphalt binder more comprehensively from chemical and micromechanical properties.
