“…When the dose of capsules continues to increase, the mechanical properties will be seriously reduced, even unable to meet the relevant speci cations [1,2]. Lot and research found that the fatigue life of modi ed asphalt mixture is greatly improved compared with conventional mixture [3,4]. Kar believes that among the different mixtures, the mixture containing 50% recycled asphalt pavement shows the best results in the elastic modulus and moisture damage resistance tests.…”

In the process of asphalt pavement maintenance management, the technical condition of the pavement is accurately predicted, its performance trend is predicted, and the right time is chosen to take targeted maintenance measures that will play a multiplier role, so predicting the technical condition of the pavement is important significance. This paper mainly studies the cluster dimensionality reduction evaluation method of the technical condition of expressway asphalt pavement. This paper summarizes the experience of regular highway inspection data inspection and analysis, and mainly studies the standardized analysis method of highway pavement inspection data, aiming to meet the data requirements at all levels through effective data analysis indicators. The experimental data in this paper show that the driving quality of the two-way pavement is good, the total average SRI is 91.2, and the evaluation is “excellent,” and the left width is slightly better than the right width; the transverse crack penetration of most reconstructed road sections is greater than 0.4, indicating that the transverse crack penetrates the road surface more serious. The experimental results of this paper show that the technical status of asphalt pavement based on cluster analysis has practical significance, and the analysis results show that the treatment effect is ideal.

“…Marshall’s method of compaction is very well considered for preparing the specimen of the hot bituminous mix in the Indian standard codes. In addition, some literature (Technical Guideline-2, 2009; Kar et al , 2017a; Modarres and Ayar, 2016) has also suggested the Marshall method of compaction (75 number of blows) to achieve the optimum binder content in association with maximum dry density to prepare the cold mix specimen. Moreover, Loizos and Papavasiliou, (2006) have also been advocated a change in design pattern from the Marshall method of mix design to a design based on performance criteria; resilient modulus, moisture resistance and indirect tensile strength for the design of cold bituminous mix.…”

Purpose Natural good-quality sources of aggregates are depleting, whereas large amount of reclaimed asphalt pavement (RAP) is produced annually. Safe disposal and use of RAP in the cold in-place recycling (CIR) using foamed bitumen could be sustainable approach where milling and mixing operations are accomplished simultaneously. This will not only help in minimizing contamination (probability) and transportation cost but also reduces the carbon footprints. Therefore, this study aims to investigate the scope of RAP utilization up to 100% and further its effect on the behavior of reclaimed asphalt foamed bituminous mix. Design/methodology/approach Reclaimed asphalt foamed bituminous mix (FBM) is still a new technique. The evidence of performance of 100% recycled pavement (CIR) is only anecdotal and lacks in systematic guidelines and literatures. Foam binder coating around the aggregates is also a concern. Therefore, this study is mainly emphasized to investigate the scope of RAP use in the FBM up to 100%. RAP content is varied in each trial, i.e. 70, 85, 100 and 0% (only fresh aggregates), to make the FBM. RAP use and its effect on the behavior of FBM in terms of resilient modulus, variation in resilient modulus with curing, rutting performance and the potential of resistance against the moisture damage are addressed. Findings Considering the laboratory studies, it can be accomplished that mechanistic properties and performance of FBM are largely influenced by RAP material and portray less susceptible characteristics against the moisture damage. FBM containing 70% RAP content exhibits maximum resilient modulus. However, use of RAP up to 100% in FBM is satisfying the minimum required specification. Originality/value Overall, the study may be helpful to highway professionals and could generate another possible option of 100% RAP replacing fresh aggregates in the flexible pavements.

“…Asphalt Recycling and Reclaiming Association; it has defined different recycling techniques such as Cold Planing, Hot Recycling, Hot In-Place Recycling, Cold Recycling, Full Depth Reclamation [3]. Considering the increase in greenhouse gas emissions by twice every 10 ° C in the production of bituminous mixtures [4], cold recycling from these methods undoubtedly stands out due to its environmental advantages [5], [6]. The main logic in recycling with foam bitumen, which is one of the recycling methods in the cold in place, is to increase the surface area of the bitumen to facilitate its mixing into recycled material [7].…”

Materials recycled with foam bitumen are promising materials for pavements economically and environmentally. However, there are different opinions in the literature about how these materials are positioned in the pavement. It is clear that their performances will not be suitable for the wearing course, but that they are used for the plant mixture base course because they contain bitumen, and that these materials will be neglected in the evaluation of these materials. In the study, 4 different foam bituminous mixes prepared with a recycled pavement material and a standard bituminous base course mix were compared in terms of the resilient modulus obtained from the uniaxial indirect tensile resilient modulus test. Gradation is the same for three of the mixtures, two of them use cement as a mineral binder, but 70/100 grade bitumen in one of these two productions and 50/70 grade bitumen in the other. In the third mixture, 70/100 grade bitumen and hydrated lime (HL)+fly ash (FA) were used. In the final mixture, 70/100 grade bitumen and cement were used as mineral binders, but gradation was changed. In addition, permanent deformation control for the final production was carried out with a triaxial cyclic compression test. It was concluded that all these variables affect the results, but the resilience modulus values obtained for all were quite close to those obtained from the bituminous base sample. Considering that the foamed bituminous mixtures will be thicker than the bituminous base course in practice, it is considered structurally appropriate to use this layer instead of the bituminous base course.
