“…At present, the RAP content in RAP recycling is mainly controlled at about 15-25% [8,9]. One of the main reasons for limiting the high content (≥30%) of RAP is that the fatigue performance of the recycled asphalt mixture is difficult to guarantee, so that the hot recycling technology of asphalt pavement has not been widely promoted and applied [10][11][12]. Conversely, on the basis of ensuring the recycling of asphalt pavement materials, the increase of RAP content will bring huge economic and social benefits [13].…”

Asphalt pavement hot recycling technology can improve resource utilization efficiency, reduce energy waste and CO2 emissions, and bring huge economic and social benefits, further promoting the realization of “carbon peak and carbon neutrality”. This paper uses single logarithmic regression fitting on the fatigue failure life of recycled asphalt mixture with high RAP content to characterize the influence of RAP content (R), stress ratio (C), loading frequency (H) and test temperature (T) on the fatigue life of recycled asphalt mixture. Subsequently, the relationship between fatigue life and stress ratio of recycled asphalt mixture, under the influence of different RAP content, loading frequency and test temperature was analyzed. The results showed that the fatigue life of recycled asphalt mixture decreased with an increase in RAP content, stress ratio and test temperature, and decreased as loading frequency increased. Fatigue life and stress ratio were found to be approximately logarithmic, and based on the relationship between fatigue equation parameters a, b and R, T, H, the fatigue prediction model for recycled asphalt mixtures with independent variables R, C, H, and T was established.

“…It should be noted that a new type of geocells, high temperature resistant, can also be used for improvement of asphalt mixture properties [47]. Additional materials for asphalt mixtures, and the suitability of many modifiers, were also investigated, such as the engine oil, cooking oil, and graphene [48][49][50].…”

Prevention and remediation measures for reflective cracks in flexible pavements

Considering the high price and the number of natural resources used in transport infrastructure, extending pavement lifetime is a priority for engineers. One of the most common issues in flexible pavement maintenance are reflective cracks, which reduce driving comfort and passenger safety. These cracks have two main origins, those initiated by shrinkage of the cement stabilized layer and the cracks reflected from the old pavement to a new overlay. During road maintenance, the usual remediation measure is to overlay and place a new asphalt wearing course over the old, deteriorated pavement surface. After an asphalt overlay is placed on the deteriorated pavement, the overlay can exhibit an identical crack pattern as the layer below. The main cause of reflective cracks is in the cement bound base course (CBC). Due to cement hydration, traffic load, and temperature oscillations, cracks may occur and propagate through upper layers. Much research has been conducted to prevent this problem. Some research, with an emphasis on recycled materials, is presented in this paper. The remediation measures include thin and thick interlayers and modification of the asphalt overlay characteristics.

“…Asphalt pavement is widely used for its smooth surface and driving comfort. However, with the high temperature in southern and western China in summer, as well as the sudden increase in traffic volume, heavy overload, and drainage traffic, asphalt pavement defects are becoming more and more prominent [ 1 ]. The properties of base asphalt are not so good that the road asphalt maintenance budget every year exceeds the budgetary allocation for new asphalt pavement construction.…”

The sustainable reuse of waste plastic as an alternative construction material has numerous environmental and economic advantages. New opportunities to recycle waste plastic in asphalt for road construction would mitigate landfill issues and significantly reduce global carbon emissions. With a clear aim to contribute to a more efficient reuse of waste plastic, this paper reutilized two types of waste plastic (polypropylene (PP) and polyethylene (PE)) as asphalt modifiers to improve the performance of asphalt pavement as well as to achieve the purpose of sustainable recycling waste plastic. Therefore, the optimal preparation parameters of plastic-modified asphalt were recommended by the orthogonal test. Then, the dispersion and modification mechanisms of plastic particles in plastic-modified asphalt were further studied by Fourier Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Differential Scanning Calorimetry (TG-DSC). The results show that the asphalt containing PP and PE shows better overall performance at high temperatures compared with the base asphalt. Furthermore, PE-modified asphalt and PP-modified asphalt exhibited optimal properties when prepared at 3000 rpm for 30 min at 170 °C. Moreover, the results of the expansion mechanism show that the main reaction process of plastic asphalt is a physical change. Finally, PP-modified asphalt and PE-modified asphalt generally perform well and are suitable for high-temperature areas. Consequentially, the results of this research promote the recycling of waste plastic, ultimately advocating the recycling of waste materials and environmental protection of pavement construction.
