Book Description
This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.

Book Description
This synthesis will be of interest to construction, maintenance, pavement design, and materials engineers, pavement contractors, and others interested in the use of open-graded friction courses (OGFC) as an asphalt concrete pavement wearing surface. Information is provided on performance benefits and limitations of OGFC, material and mixture properties, and current construction practices in use in the United States and Europe. Advances in mixture design and construction techniques have overcome several of the performance limitations identified in early applications of OGFC, as well as enhanced the performance benefits associated with OGFC use. This report of the Transportation Research Board describes the current state of the practice with respect to the use of OGFC. Experience with the design, construction, and performance of OGFC is summarized, based on a review of the literature, documentation of experience from applications in the U.S. and Europe, and site visits to several states.

Book Description
Paving Our Ways covers the international history of road paving in an interesting, readable and technically accurate way. It provides an overview of the associated technologies in a historical context. It examines the earliest pavements in Egypt and Mesopotamia and then moves to North Africa, Crete, Greece and Italy, before a review of pavements used by the Romans in their magnificent road system. After its empire collapsed, Roman pavements fell into ruin. The slow recovery of pavements in Europe began in France and then in England. The work of Trésaguet, Telford and McAdam is examined. Asphalt and concrete slowly improved as paving materials in the second part of the 19th century. Major advances occurred in the 20th century with the availability of powerful machinery, pneumatic tyres and bitumen. The advances needed to bring pavements to their current development are explored, as are the tools for financing, constructing, managing and maintaining pavements. The book should appeal to those interested in road paving, and in the history of engineering and transport. It can also serve as a text for courses in engineering history.

Book Description
This work presents the results of RILEM TC 237-SIB (Testing and characterization of sustainable innovative bituminous materials and systems). The papers have been selected for publication after a rigorous peer review process and will be an invaluable source to outline and clarify the main directions of present and future research and standardization for bituminous materials and pavements. The following topics are covered: - Characterization of binder-aggregate interaction - Innovative testing of bituminous binders, additives and modifiers - Durability and aging of asphalt pavements - Mixture design and compaction analysis - Environmentally sustainable materials and technologies - Advances in laboratory characterization of bituminous materials - Modeling of road materials and pavement performance prediction - Field measurement and in-situ characterization - Innovative materials for reinforcement and interlayer systems - Cracking and damage characterization of asphalt pavements - Recycling and re-use in road pavements This is the proceedings of the RILEM SIB2015 Symposium (Ancona, Italy, October 7-9, 2015).

Book Description
A study was conducted by the Arizona Department of Transportation to evaluate the potential noise reduction benefits of using Asphalt Rubber Asphalt Concrete Friction Course (ARACFC) as an overlay for Portland Cement Concrete Pavements (PCCP). Comparative noise measurements were performed on several ARACFC and PCCP freeway segments. Third-octave frequency measurements were also performed to compare the frequency content of the noise generated by the two pavement types. Two separate measurement techniques were used to collect noise data. First, roadside traffic noise measurements were performed on adjoining freeway segments that consisted of different pavement types. For these measurements, two noise meters were positioned at equal distances from the adjoining freeway segments, and roadside traffic noise levels were measured simultaneously. The second measurement technique consisted of on-road tire-pavement noise measurements. For these measurements, a specially made bracket was clamped to the frame of a test vehicle, and a noise meter microphone was secured near the tire-pavement contact area. Noise readings were recorded as the test vehicle traveled at highway speeds over various pavement surfaces. Noise frequency data were collected using both measurement techniques.
