In order to further promote the development of functional pavement technology, a Special Issue of \"Achievements and Prospects of Functional Pavement\" has been proposed by a group of guest editors. To reach this objective, articles included in this Special Issue are related to different aspects of functional pavement, including green roads to decrease carbon emission, noise, and pollution, safety pavement to increase skid resistance by water drainage and snow removal, intelligent roads for monitoring, power generation, temperature control and management, and durable roads to increase service life with new theory, new design methods, and prediction models, as highlighted in this editorial. functional pavement; green road; safety pavement; intelligent road; durable road; pavement materials; asphalt pavements  
A Special Issue of \"Achievements and Prospects of Functional Pavement: Materials and Structures\" has been proposed and organized to present the recent achievement of functional pavement, and to promote the development of functional pavement technology. This Special Issue contains 20 technical articles [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20], which have been peer-reviewed under the journal's rigorous review criteria. The collection includes invited papers from experts in international communities and articles that have been selected from the 2019 World Transport Convention (WTC) held in June 2019 in Beijing, the 4 th International Conference on Transportation Infrastructure and Materials in Jinan, Shandong, China in 2019, and the 5 th Chinese-European Workshop on Functional Pavements in 2019 in Changsha, China. Research institutions in pavement research, such as Changsha University of Science & Technology (5 papers), Delft University of Technology (4 papers), Michigan Technological University (3 papers), Southeast University, Khalifa University of Science and Technology, Nanjing Institute of Technology, Tongji University, Dongguan University of Technology, Hefei University of Technology, Korea University of Technology and Education, Jilin University, Lanzhou Jiaotong University, Shijiazhuang Tiedao University, Shenyang Jianzhu University, and Technological University Dublin, have contributed their research achievements to this Special Issue. A summary of the articles is given in this editorial. Research on the application of waste material in pavement construction is considered to be one of the most economical ways to achieve sustainable, designed green pavements. [PERSON] et al. [1] investigated the use of waste oyster shells as a novel bio-filler in pavement, which is not only able to improve the quality of pavements but also to reduce the cost of their construction and solve the waste problem. [PERSON] et al. [2] studied the complex interaction between bitumen and crumb rubber as well as the addition of warm-mix additives, and proposed a second-order polynomial function to characterize the viscosity-temperature dependence. [PERSON] et al. [3] developed a new modified open grade friction course (OGFC) by replacing the fine aggregate below 4.75 mm in OGFC with oil shale waste, and a silane coupling agent modifier was used to assist modification. The modified OGFC preparation is an effective technique for improving the strength and stiffness of the OGFC and reducing environmental degradation. Materials modification technologies are thus widely used in pavement engineering to improve the performance of pavement materials. In this Special Issue, rock asphalt (RA) [4; 5], diatomic [4], Styrene-Butadiene Rubber (SBR) [5], nano-CaCO3 [5], and Bio-Char [6] were used as modifiers for bitumen and were evaluated in detail. The viscoelastic properties, fatigue properties, rutting resistance, anti-cracking properties, and microstructure of bitumen are presented in this Special Issue. High technologies are applied in intelligent pavement construction, which improves the functions or endows new functions to pavements. [PERSON] et al.
