“…Several studies have investigated the incorporation of various wastes such as construction and demolition wastes, end-of-life tires, reclaimed asphalt pavement, used motor oils, plastics, and asphalt shingles into road pavement layers [2][3][4][5][6][7][8][9][10][11][12].…”

h i g h l i g h t sRecycled concrete aggregates (RCA) have poor quality than natural aggregates. A review on the properties of hot-mix asphalt (HMA) with RCA is conducted. Most studies report a high stripping potential of these mixtures. Several treatments help mitigate its unsatisfactory moisture damage resistance. Test stretches of HMA with RCA exhibited good performance. a b s t r a c tRecycled concrete aggregates (RCA) appear to be suitable materials to use in hot-mix asphalt (HMA) for flexible road pavements. However, the poor quality of RCA results in different engineering properties of an HMA using RCA compared to mixtures composed of natural aggregates. This paper presents a review on the properties of HMA with RCA. Varied laboratory results were obtained, likely because of the heterogeneous nature and origin of the RCA. Nevertheless, a majority of the studies report a high stripping potential of RCA mixtures. Several treatments help mitigate this problem. Additionally, select test stretches of the RCA mixture exhibited good performance.

“…Among these additives, LDPE and HDPE have been subjected to more studies compared to other waste polymer materials [15,[21][22][23]. In recent years the use of waste PET in asphalt mixture has become popular [24][25][26][27] since it is one of the main packaging materials, and a large amount of waste PET is being produced worldwide. In other words, the usage of natural resources and environmental pollution could be reduced by using waste PET as an alternative in road construction projects.…”

“…Some studies [1][2][3][4] have shown that the fatigue performance of a modified asphalt mixture is obviously better than that of a base asphalt mixture due to the addition of an SBS modifier. Some studies [2][3][4][5][6][7] show that the addition of PE (polyethylene), PA (polyamide), and warm mixing agents will change the fatigue performance of the asphalt mixture. Many scholars [4][5][6][7][8][9][10][11][12] have chosen different fatigue setups to carry out fatigue tests.…”

The four-point bending beam fatigue test (4PB), two-point bending trapezoidal beam fatigue test (Trapezoidal Beam), and Overlay Tester (OT) are used to evaluate the fatigue performance of six kinds of asphalt mixtures that are widely used in engineering, and newly developed ones. The result shows that, in all three kinds of fatigue tests, the fatigue performances of the 6% SBS (styrene-butadiene-styrene block copolymer) modified asphalt mixture is the best, and those of the 10% WPE (waxed polyethylene) + 3% SBS, 4% SBS + 0.4% PA610, and 4% SBS modified asphalt mixture are good. The fatigue performances of the warm modified mixing agent and the base asphalt mixture are the worst. An increase in SBS content can effectively improve the fatigue performance of the asphalt mixture. The fatigue performance of the SBS-modified asphalt mixture can be improved by the addition of WPE and PA610. In different tests, the ranking of fatigue performance of the asphalt mixture is similar, and the specific ranking is slightly different. The three different fatigue tests can be used simultaneously to obtain a more comprehensive and objective evaluation in the R&D process for a new modified asphalt. The three fatigue tests process shows that more precise forming and cutting technology is needed, as the strain range used in the 4PB test is very wide, and the number of samples used in each group is small. The preparation of the Trapezoidal Beam test samples is complex; the amount of test data is huge and has high precision, which is suitable for scientific research instead of a field laboratory, and the strain range of the test is moderate in the three methods. The strain range of the OT test is the narrowest; the test specimen is relatively simple to prepare, and the fatigue performance of a specific modified asphalt mixture can be obtained quickly in a simple laboratory.
