Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of this research study may be stated as follows: Determine if surface characteristic measurements can be correlated to wet-pavement crashes in Ohio; Provide improved guidance on the use of ribbed versus smooth tires for pavement surface friction testing in Ohio, including the identification of suggested minimum surface friction numbers associated with each tire type; Provide recommended desirable or target surface friction numbers as a function of site categories and friction demand. Accomplishments of these objectives will help ODOT address their goal of reducing total crashes 10 percent and rear-end crashes by 25 percent by 2015.

Book excerpt: A small-scale, wet-weather accident study was conducted in the years 1981 to 1983 as part of a wider study on pavement texture. The researchers were notified of wet-weather accident occurrences, and the skid resistance was measured as soon as possible after the accident, usually within one day, but never more than two days. During the study period, 79 such sites were tested, 21 of which had multiple accidents. All sites were tested with the ribbed and blank test tires. Similar tests were made on control sections within 1.6 km (1 mile) of the accident sites. These were selected to have geometric and traffic characteristics similar to those of the accident sites. As it turned out, the data base was too small to warrant definitive conclusions. Uncertainties about accident causation were reflected in the fact that the data from the control sites were not significantly different from those of the accident sites. The results, however, show a trend consistent with findings by other researchers. Skid resistance measured with the blank tire is not only lower than that measured with the ribbed tire, but is also better as a predictor of skidding accident potential. Wet-weather accident data from Florida were also analyzed, and the results reinforced this conclusion. The use of data from both the blank and the ribbed tire for pavement evaluation is recommended for future study.

Book excerpt: 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.
