There is the need, therefore, for a total understanding of the phenomenon to be able to counter its occurrence. The fatigue resistance of hot mix asphalt concrete (HMAC) has been estimated using approaches ranging from empirical methods to mechanistic-empirical methods to purely mechanistic methods.

Abstract:
AbstractIn order to solve the problem of high-value utilization of coal-to-oil residual direct coal liquefaction residual asphalt, it is compounded with SBS and aromatic oil to modify the matrix asphalt, and 9 compounding schemes are designed using orthogonal experimental methods. Dynamic frequency sweep tests using DSR and a simplified Carreau equation model fitted to the complex viscosity to obtain its zero shear viscosity; the creep recovery rate, irrecoverable creep flexibility and irrecoverable creep flexibility difference of each modified asphalt were determined by MSCR at different temperatures and stress levels, and the high temperature rheological properties of 9 composite modified asphalts were evaluated by grey correlation analysis of zero shear viscosity and high temperature rheological parameters. Bending beam rheological experiments were carried out on the aged composite modified asphalt to analyse its low temperature rheological properties based on the viscoelastic parameters and linear fitting of the Burgers model. The results show that: The high temperature deformation resistance of DCLR composite modified asphalt are better than the matrix asphalt, the most influential modifier is SBS, and the higher the dose, the stronger the high temperature deformation resistance. The unrecoverable creep flexibility Jnr3.2 at 70 °C can better respond to the high temperature performance of asphalt, the ratio of 9% DCLR + 4% SBS + 2% aromatic oil DCLR composite modified asphalt with the best high temperature performance. Burgers model can better reflect the creep process of asphalt, DCLR composite modified asphalt has some defects in low temperature performance, the higher the dose of DCLR, the poorer the low temperature performance of the composite modified asphalt. The low temperature sensitivity of DCLR composite modified asphalt has been reduced, low temperature crack resistance has been slightly enhanced.

Abstract:
AbstractThe fatigue performance of asphalt binder can be significantly increased by incorporating nanosilica, but due to the poor dispersion of nanosilica in asphalt, high mechanical energy is required to achieve good homogeneity. The viscosity of asphalt is nearly double when 3% nanosilica is added. Consequently, the mixing temperature of asphalt with aggregate is dozens of degrees higher to compensate for its high viscosity. To solve this problem, modification of nanosilica was introduced and the effects of its performance on asphalt are reported here. Several types of nanosilica at various dosages were modified and characterized by Fourier-transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The properties of asphalt, such as viscosity, rutting, fatigue, softening point, penetration and ductility were investigated. The viscosity of asphalt with 3% modified nanosilica was 80% lower than that of the asphalt with unmodified nanosilica and a 20 °C reduction in temperature for mixing the asphalt binder with aggregate was achieved. Moreover, the rutting and fatigue performance of asphalt with modified nanosilica were significantly enhanced. The asphalt with modified nanosilica not only had lower viscosity but also has similar performance to asphalt with unmodified nanosilica. The asphalt with modified nanosilica had excellent performance and thus good practical application potential.

Abstract:
AbstractThe compaction characteristics of asphalt concrete materials have a decisive impact on the degree of field compaction. Therefore, the study of the compacting law of composite modified asphalt mixture has important guiding significance for the field construction of pavement. This study used a gyratory compactor (SGC) to analyze the compaction characteristics of composite modified asphalt concrete materials from the two dimensions of asphalt-aggregate ratio and gradation. The test added 10% PE modifier by mass of asphalt and 0.2% polymer fiber. The compaction characteristics of LA-10 (low-void asphalt concrete materials), SMA-10, and AC-10 gradations under asphalt-aggregate ratio of 7.5%, 8.0%, and 8.5% were studied and compared with the compaction situation of the commonly used EA-10 for steel bridge deck pavement. The results showed that with changes in the asphalt-aggregate ratio, the trend of the mixture voidage and compaction curve was consistent. The LA-10 mixture reached the target voidage range at an asphalt-aggregate ratio of 7.5%, with good workability, while the AC-10 and SMA-10 mixtures reached the target voidage range at an asphalt-aggregate ratio of 8.0%, and were easier to compact. The compaction density energy index was SMA-10 &gt; AC-10 &gt; LA-10 &gt; EA-10, and the compaction ease of LA-10 was relatively close to that of epoxy asphalt mixture EA-10. According to the above compaction characteristics, LA-10 is suitable for the lower layer of pavement, and SMA-10 and AC-10 are suitable for the upper layer of pavement.

Abstract:
AbstractDifferent indices have various capabilities to evaluate the high-temperature performance of modified asphalt mixtures. This study aims at investigate the discriminability of high-temperature performance indices. The values of five indices were determined from wheel tracking test, Marshall test and uniaxial penetration test, including dynamic stability (DS), comprehensive stability index (CSI), maximum rutting depth (RD), Marshall stability (MS), and uniaxial penetration strength (UPS). The discriminability of five indices was further examined by entropy weight method and CRITIC method, respectively. The results show that DS, MS and UPS are not appropriate to evaluate the high-temperature performance of modified asphalt mixtures, but CSI and RD show preferable distinguishing ability to evaluate the high-temperature performance. As a consequence, RD is recommended to be employed as secondary index to supplement the CSI in wheel tracking test. The findings of this study will contribute to the optimization of evaluation on high-temperature performance of modified asphalt mixtures.

This review paper provides a comprehensive comparative analysis of the application of Aspha-min in Warm Mix Asphalt (WMA) technology, with a particular focus on its performance, environmental impact, and economic benefits in comparison to traditional Hot Mix Asphalt (HMA). HMA has long been the standard for asphalt pavement, known for its robust performance and durability. However, production and compaction of HMA requires high temperatures, typically between 140-160°C. Therefore, widespread use of HMA has raised concerns about its environmental impact due to high fuel and energy consumption a

Abstract:
In order to enhance the properties of asphalt mix, especially rutting resistance in Iraq due to high temperature, different modifier types have been adopted. Recent studies have shown that in Iraq, the polymer in the form of SBS is highly effective and gives good results in resistance to rutting and other defects. However, its use increases the cost of asphalt concrete and its difficulty storing, leading to the investigation of alternative polymers that should be more reasonable than the SBS polymer. This study examined a polymer named PROpolymer MA123 to measure its applicability to modified

The complex factors during the asphalt production process and subsequent traffic loading, climatic and weather conditions lead to a decrease in durability of asphalt thereby reducing pavement surface service life. The physical and mechanical properties of asphalts change over time and are different than at the beginning. The paper focuses on the laboratory research on effect of thermo-oxidative aging (short term and long term), ultraviolet radiation and water on stiffness and indirect tensile strength of asphalt mixtures.

The use of crumb rubber made from end of life tyres for asphalt mixtures modification in order to improve their properties or just utilize waste products may be considered as potential solution. Crumb rubber can be used as a bitumen modifier (wet process) or supplementary component of the asphalt mixture (dry process). Dry modification process has more potential due relatively unsophisticated technology and higher possible to use amount of crumb rubber comparing to the wet process. The performance of asphalt mixtures modified by dry process mainly depends on several factors as crumb rubber typ

Abstract. Olive mill wastewater (OMW) is a liquid by-product generated from olive oil processing and represents a significant environmental concern regarding their disposal and management. This paper was carried out to examine the potential use of the Olive Mill Wastewater Ash (OMWA) as a modifier for asphalt binder. An asphalt binder with a penetration grade of 60/70 was used as the control binder in this study. OMWA was added to the base asphalt binder at various amounts (1%, 2%, 3%, 4%, and 5% by weight of asphalt binder). Asphalt binder's physical and rheological properties, such as penetr

Abstract:
The increased use of softer binders in Illinois over the past decade is primarily attributed to the increased use of recycled materials in asphalt pavement construction. The shift in demand of using PG 58-28 over PG 64-22 has resulted in potential alternative methods to produce softer binders more economically using proprietary products. However, there are challenges in using these proprietary products for asphalt modification because of uncertainty in their long-term performance and significant variability in binder chemistry.

Plastic pollution has become one of the major concerns in the world. Plastic waste is not biodegradable, which makes it difficult to manage waste plastic pollution. Recycling and reusing waste plastic is an effective way to manage plastic pollution. Because of the huge quantity of waste plastic released into the world, industries requiring a large amount of material, like the pavement industry, can reuse some of this mammoth volume of waste plastics. Similarly, the use of reclaimed asphalt pavement (RAP) has also become common practice to ensure sustainability. The use of recycled waste plasti

Abstract:
Transportation has an enormous impact on the U.S. economy and on the lives of all Americans. Many modes of transportation rely on pavement, but pavement conditions deteriorate over time because of the combined effects of traffic and climate. Exposure to moisture often causes premature failure of asphalt pavements as it reduces the stiffness of the asphalt and enables stripping of the asphalt from the aggregate. This research evaluates the effectiveness of clay nanomaterials (i.e., nanoclays) in improving the resistance of hot mix asphalt (HMA) to moisture damage and compares the enhancement re
