Skidding Measurement Techniques


Book Description

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.
















Handbook of Antiblocking, Release, and Slip Additives


Book Description

Handbook of Antiblocking, Release, and Slip Additives, Fourth Edition, is the only comprehensive reference available on the subject of antiblocking, release, and slip additives, which are of high industrial importance. These additives are used to alter the properties and performances of polymers, minimizing adhesion, aiding separation, and improving the efficiency and cost of processing methods. These characteristics make additives an important topic across the spectrum of industry sectors that employ plastics and polymers. Fully updated to include the latest research and additives, the book considers all essential aspects of chemistry, physical properties, influence on properties of final products, formulations, methods of incorporation, analysis, and effects on health and environment. It also provides a complete analysis of existing literature and patents. Processing is discussed in detail, including coverage of types and concentrations, the effect of the additives on the process and product properties, advantages and disadvantages, and examples of formulations. This combination of data and performance analysis makes the book a vital source of information for industry research and development as well as academia. - Outlines the essential aspects of chemistry, physical properties, influence on properties of final products, formulations, analysis, and effects on health and environment - Reviews the latest literature, related patents, and includes all new information currently available across 18 chemical families - Covers processing including the types and concentrations, effects of additives, and examples of formulations
