Available in PDF, EPUB and Kindle. Book excerpt: The real objective in skid testing is to determine the contribution of the pavement to tire-pavement friction. Friction force between a standard tire and the pavement is measured because there is, at present, no direct way of characterizing the pavement surface. Friction force depends on pavement and tire; therefore, the tire cannot properly be regarded as part of the measuring system. The skid tester, without tire, is discussed on principles of measurement techniques, and the conclusion is reached that statistical methods must be employed to compensate for the lack of precision in skid testing. Skid tester dynamics do not affect mean skid resistance; therefore, no basic design changes are required. Precision can be improved by tighter test procedures. These require improved training and awareness of operators, improved control of test speed, lateral position, and pavement watering.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the first half of a diverse collection of chapters in the field of materials and infrastructures in transport systems, which illustrate the technological and methodological innovations required to rise to the challenge of building more sustainable transport infrastructures for the future. The authors explore the potential of these sustainable solutions to improve the performance and efficiency of materials and infrastructures, with a reduced environmental impact and lower cost. Theoretical and practical case studies address a variety of topics including circular economy and sustainability, the impacts of climate change, durability, lifecycle, auscultation and the monitoring of infrastructures. This book provides transport researchers and professionals with a better understanding of the current and future trends in these innovative fields, enabling them to put into practice new technologies and methods of design and management, so that new solutions can become current practices to truly improve modern transport systems.

Available in PDF, EPUB and Kindle. Book excerpt: Two important goals of ergonomics are the comfort, and the health and safety of workers. In many ways these are mutually compatible, for where health and safety is jeopardized, the discomfort results. Most work-related injuries can be viewed as biochemical damage to a tissue or organ; ultimately all injuries are sustained by tissues. Writte

Book excerpt: Paper 1: Between December, 1958, and September, 1959, over 300 pavement surfaces, including 6 surface types, were skid tested in Florida using a tapley decelerometer mounted in a passenger vehicle. The skid tests were conducted on a wet surface at 40 mph. Paper 2: The coefficients of friction were experimentally determined for rubber tires on road surfaces in relation to slip when a wheel is braked. The method and equipment are described. Paper 3: The procedure for using a pendulum-type (tapley) decelerometer to measure the coefficient of friction is an empirical one in which the test car is braked for 1 sec and the maximum deceleration recorded by the device. Paper 4: Data are presented for many different types of pavements when dry, set, and snow- and ice-covered, with the latest types of rubber tires indicating the importance for precise measurements of coefficients of friction for the design of modern streets and highways and for developing programs for the prevention of skidding accidents.
