Laboratory fatigue test has been widely used by researchers and engineers to assess the fatigue performance of asphalt mixture, due to its low cost, high efficiency, and strong operability. To ensure performance assessment reliability, fatigue test operated in the laboratory needs to simulate the loading and environmental conditions occurring in the field asphalt layer. As a result, loading setups in laboratory fatigue tests, including loading mode, loading frequency, loading waveform, temperature, and the controlled mode, have been carefully devised by researchers. This paper reviews the above common setups in fatigue tests, which aims to illustrate the classical and latest considerations as well as ideas proposed by researchers for improving fatigue test procedures. As fatigue response data of asphalt mixture is measured from fatigue test, an analysis method is required to process the data and identify fatigue behaviors of the material. Presently, the frequently-used fatigue data analysis methods include the fatigue life model, stiffness-modulus-based method, energy-based method, and viscoelastic continuum damage (VECD) method. This paper also provides a review survey on the main concepts, indicators, and models included in those methods to facilitate their applications. Meanwhile, the latest research progress and outputs related to the four methods are also introduced and discussed to reveal the state-of-the-art developments in this research area.</p></div>","PeriodicalId":100830,"journal":{"name":"Journal of Road Engineering","volume":"2 4","pages":"Pages 279-308"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2097049822000609/pdfft?md5=e9847149b9d16545503b6a191c962e31&pid=1-s2.0-S2097049822000609-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89029242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application effect of combined base long-life asphalt pavement, which has been widely promoted, is evaluated. At the same time, taking the Binda perpetual pavement test road in Shandong Province as an example, the dynamic response and long-term performance evolution of long-life asphalt pavement are analyzed over a period of more than 17 years. Sections S1, S2, and S3 present information about full-depth asphalt pavement. Section S4 describes combined base asphalt pavement. The results show that the maximum strain of S1–S4 is within the endurance strain limit. S1, S2, S3 and S4 are all expected to be long-life asphalt pavements. In the current study, Sections S1–S4 were maintained in good condition during a service period of more than 17 years with no structural cracks and good deflection, rutting, and IRI indexes. The deflection index was stable without growth, and the IRI was also relatively stable following the opening to traffic. The rutting depth underwent a slight cumulative increase within 8 years of opening, and then stabilized. The average rutting depth over the 17-year period was less than 15 ​mm. Therefore, S1–S4 meet the design standards required for use as long-life pavements.

One of the most important reasons for this shortcoming is the problem of false particle size and pseudo gradation of RAP materials. Therefore, identifying suitable asphalt-aggregate separation technology is essential for improving the utilization of RAP materials in recycled asphalt mixture and enhancing the construction quality of recycled asphalt pavement. To address this, the paper performed a systematic review of asphalt-aggregate separation technologies for processing RAP materials and their prospects. Firstly, based on the composition of the asphalt mixture and the characteristics of RAP materials after aging, the key RAP separation technologies were proposed.

Moreover, the advantages and disadvantages of various separation technologies were discussed by comparing them with the related technologies in the petrochemical industry.

The rheological properties and microscopic mechanism of OCRMA were characterized by dynamic shear rheological test, multiple stress creep recovery (MSCR) test, BBR test and infrared spectroscopy. The results show that the dissolution degree of waste crumb rubber is improved after WCO activation, and the compatibility with asphalt components is enhanced, and the stable cross-linking structure is formed, which improves the asphalt performance. The several new absorption peaks, which were obvious, were all caused by the composition of WCO, that is, there was no significant chemical change during the interaction between the activated crumb rubber and base asphalt. Compared with the common waste crumb rubber modified asphalt (CRMA), activation with WCO can significantly reduce the viscosity of CRMA, decrease the difference of segregation softening point by 27%, and enhance the low temperature performance by 30%. The aging degree is greatly reduced, and the anti-aging performance of OCRMA is increased by about 20% with the same dosage.

However, because of inefficient handling and utilization, these wastes are becoming a larger issue. As a result, one initiative is to use these wastes in the pavement industry as sustainable materials. However, there is still a lack of understanding about the wider incorporation of palm oil waste in asphalt pavement and its performance. This study examines existing literature on the use of various wastes in the pavement industry, including palm oil clinker (POC), palm oil fibre (POF), palm kernel shell (PKS), and palm oil fuel ash (POFA). As a result, this paper presents a systematic review and scientometric investigation of related study publications on many uses of palm oil waste in the asphalt pavement industry and its performance from 2009 to 2022. The VOSviewer application was used to conduct the scientometric study analysis. The relationship between interactions detected in co-authored country studies cited sources of co-citation, and the keyword of the co-occurrence and publication source enabled the identification of the research gap. According to the systematic literature review, 40%–60% POC can be used to fine aggregate for optimal performance, while 0–100% PKS can be used to replace coarse aggregate. In addition, 50%–80% POFA or POC fine (POCF) can be used as a filler replacement, 5%–8% POCF or POFA as a bitumen modifier, and 0.3% POF as a stabilizing additive. Furthermore, the study demonstrates that the safety of utilizing wastes with more than 50% CO₂ emissions can be curtailed with minimal heavy metal leaching and radioactivity levels. The scientometric analysis may encourage researchers to seek out gaps in the literature that will aid in the long-term, multifaceted use of palm oil wastes in the asphalt pavement industry. Furthermore, the study recommends employing and researching the enormous potential of using palm oil waste in the pavement sectors because they are more sustainable and have better performance.

It is achieved through optimizing pavement structural and thickness design under specified climate and traffic conditions using advanced M-E principles, thereby minimizing economic costs and environmental impact. However, the implementation of AASHTO M-E design for low-volume concrete pavements using AASHTOWare Pavement ME Design (Pavement ME) software is often overly conservative. This is because Pavement ME specifies the minimum design thickness of concrete slab as 152.4 ​mm (6 in.). This paper introduces a novel extension of the AASHTO M-E framework for the design of low-volume joint plain concrete pavements (JPCPs) without modification of Pavement ME. It utilizes multi-gene genetic programming (MGGP)-based computational models to obtain rapid solutions for JPCP damage accumulation and long-term performance analyses. The developed MGGP models simulate the fatigue damage and differential energy accumulations. This permits the prediction of transverse cracking and joint faulting for a wide range of design input parameters and axle spectrum. The developed MGGP-based models match Pavement ME-predicted cracking and faulting for rigid pavements with conventional concrete slab thicknesses and enable rational extrapolation of performance prediction for thinner JPCPs.

(1) Self-healing construction materials have the potential to significantly extend the service life of construction elements. Urban and industrial wastes such as food waste, biomass, metals have been used to create self-healing construction materials that are more environmentally friendly. (2) Self-cleaning construction materials not only remove pollution by repelling water on their superhydrophobic surface, but also cut building and infrastructure maintenance costs, while improving cities' air quality by degrading pollutants such as NO_<em>x</em>. Pavement engineers have exploited self-cleaning characteristic to facilitate the de-icing of pavements and lengthening the service life of pavements. (3) Self-rejuvenating materials including bio-oils can revitalize materials and delay aging; bio-oils can also be used to make bio-binders, thereby reducing the need for petroleum-based binders. The optimum concentration of bio-oil for asphalt modification depends on the chemical structure of oils. Still, regardless of dosage, self-rejuvenating binders improve asphalt workability and performance at low temperatures and increase the resistance of the asphalt mix to fatigue and cracking. This review also identified critical research gaps, including (1) the lack of a reliable, unified, and standard method to accurately measure construction materials’ self-healing, self-cleaning and self-rejuvenating properties; (2) the lack of long-term field performance data to conduct comprehensive life cycle assessment and life cycle analysis; (3) the lack of accurate technoeconomic analysis to facilitate market entry of abovementioned solutions.
