"This report provides technical information on pervious concrete's application, design methods, materials, properties, mixture proportioning, construction methods, testing, and inspection. The term 'pervious concrete' typically describes a near-zero-slump, open-graded material consisting of portland cement, coarse aggregate, little or no fine aggregate, admixtures, and water." [p. 1]
Sustainable Concrete Made with Ashes and Dust from Different Sources: Materials, Properties and Applications focuses on individual materials, addressing material characterization, their role in the strength and durability of construction materials, and structural applications. Each chapter reflects the current state-of-the-art in terms of the effective and efficient use of the material. Types of ashes covered are Coal Fly Ash, Coal Bottom Ash, Bagasse Ash, MSW Ash, Red Mud, Waste Marble Dust, Sewage Sludge Ash, and Cement Kiln Dust. This book is useful for civil engineers in the design and development of sustainable concrete by utilizing such types of ashes and researchers involved in the design and formulation of new cementitious materials. - Focuses on different types of ashes derived from various sources for use in the development of sustainable concrete - Discusses the economic and environmental impacts, normative restrictions, and implementation in codes and standards related to the use of these by-products/wastes in concretes - Includes coverage of the impact of dust from construction and demolition wastes
Bearing Capacity of Roads, Railways and Airfields includes the contributions to the 10th International Conference on the Bearing Capacity of Roads, Railways and Airfields (BCRRA 2017, 28-30 June 2017, Athens, Greece). The papers cover aspects related to materials, laboratory testing, design, construction, maintenance and management systems of transport infrastructure, and focus on roads, railways and airfields. Additional aspects that concern new materials and characterization, alternative rehabilitation techniques, technological advances as well as pavement and railway track substructure sustainability are included. The contributions discuss new concepts and innovative solutions, and are concentrated but not limited on the following topics: · Unbound aggregate materials and soil properties · Bound materials characteritics, mechanical properties and testing · Effect of traffic loading · In-situ measurements techniques and monitoring · Structural evaluation · Pavement serviceability condition · Rehabilitation and maintenance issues · Geophysical assessment · Stabilization and reinforcement · Performance modeling · Environmental challenges · Life cycle assessment and sustainability Bearing Capacity of Roads, Railways and Airfields is essential reading for academics and professionals involved or interested in transport infrastructure systems, in particular roads, railways and airfields.
Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.
This book gathers the proceedings of an international conference held at Empa (Swiss Federal Laboratories for materials Science and Technology) in Dübendorf, Switzerland, in July 2020. The conference series was established by the International Society of Maintenance and Rehabilitation of Transport Infrastructure (iSMARTi) for promoting and discussing state-of-the-art design, maintenance, rehabilitation and management of pavements. The inaugural conference was held at Mackenzie Presbyterian University in Sao Paulo, Brazil, in 2000. The series has steadily grown over the past 20 years, with installments hosted in various countries all over the world. The respective contributions share the latest insights from research and practice in the maintenance and rehabilitation of pavements, and discuss advanced materials, technologies and solutions for achieving an even more sustainable and environmentally friendly infrastructure.
This book contains research papers presented at the 7th International Conference on Civil Engineering, which was held in Singapore from 24-26 March 2023. Significant results contained in the book show the importance of technology in solving engineering issues throughout the world. Highlighted topics include climate change, disaster relief, resilience, pollution control and management techniques for construction, mitigation and adaptation. Many techniques are utilized in a variety of contexts to solve engineering and urban management problems in both developed and developing countries. This volume consists of refereed submissions authored by a wide variety of international researchers and practitioners from many perspectives discussing emerging issues in civil and environmental engineering. Practical solutions to worldwide issues in hazard mitigation, pollution control, transportation infrastructure and energy production are emphasized. The chapters provide an in-depth look at current issues in these areas of engineering that should benefit interested individuals at all levels of expertise.
