Waste polymers have been studied for various applications such as energy generation and biochemical production; however, their application in asphalt roads still poses some questions. Over the last decade, several studies have reported the utilization of waste plastics in roads using different methodologies and raw materials, but there is still significant inconsistency around this topic. What is the right methodology to recycle waste plastics for road applications? What is the correct type of waste plastics to be used in road applications? What environmental concerns could arise from the use of waste plastics in road applications? Plastic Waste for Sustainable Asphalt Roads covers the various processes and techniques for the utilization of waste plastics in asphalt mixes. The book discusses the various material properties and methodologies, effects of various methodologies, and combination of various polymers. It also provides information on the compatibility between bitumen and plastics, final asphalt performance, and environmental challenges. - Discusses the processes and techniques for utilization of waste plastics in asphalt mixes. - Features a life-cycle assessment of waste plastics in road surfaces and possible Environmental Product Declarations (EPD). - Includes examples of on-field usage through various case studies.
Roads and Airports Pavement Surface Characteristics contains the papers presented at the 9th International Symposium on Pavement Surface Characteristics (SURF 2022, Milan, Italy, 12-14 September 2022). The symposium was jointly organized by the Italian company that manages Italy’s National Roads (ANAS –Ferrovie dello Stato Italiane Group), the World Road Association (PIARC) and Politecnico di Milano. The contributions aim to improve the quality of pavement surface characteristics while accomplishing efficiency, safety, sustainability, and addressing new generation mobility needs. The book covers topics from emerging research to engineering practice, and is divided in the following sections: Advanced and performing construction methods and equipment Next generation mobility Data monitoring and performance assessment Surface features and performances| Maintenance and preservation treatments Pavement management Economic and political strategies Safety and risk issues Minimizing road impacts Sustainability and performances issues about materials and design Pavements surfaces and urban heat islands Weather conditions impact Airport pavements Roads and Airports Pavement Surface Characteristics is of interest to academics, engineers and professionals in the fields of pavement engineering, transport infrastructure, and related disciplines.
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
Every day, millions of people get in their cars and trucks and hit the road. In order to support this huge volume of traffic, a strong system of highways and roads is essential. This comprehensive book examines how early trails and dirt roads eventually led to the high-speed freeways that now connect our cities, states, and countries. Readers are introduced to various types of roads, important rules and safety measures, and the many workers who ensure the maintenance and development of our highway system. Color photographs and fun facts accompany high-interest text in this first-hand look at a complex and crucial network.
"Asphalt: A History" provides a narrative history of asphalt and its effects from ancient times to the modern day. Although asphalt creates our environment, it also threatens it"--
From animal paths to superhighways, transportation has been the backbone of American expansion and growth. This examination of the interstate highway system in the United States, and the forces that shaped it, includes the introduction of the automobile, the Good Roads Movement, and the Lincoln Highway Association. The book offers an analysis of state and federal road funding, modern road-building options, and the successes and failures of the current highway system.
