Interlocking concrete pavements are extensively used in low-speed urban and rural roads throughout Europe and are seeing increased use as an alternative to asphalt and cast-in-place concrete in the United States. A proposed new ASTM International standard will address the management by city and county transportation agencies of roads made from interlocking concrete pavements. The proposed new…, ASTM Committee E17 Next Meeting:, June 5-6, 2011, State College, Pa., Technical Contact:, David R. Smith, Interlocking Concrete Pavement Institute, Herndon, Va., Phone: 703-657-6900, ext. 201; dsmith@icpi.org, ASTM Staff Contact:, Daniel Smith, Phone: 610-832-9727; dsmith@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8857

Traffic monitoring is a means of counting and classifying vehicles and measuring vehicle flow characteristics, such as vehicle speed, lane occupancy, turning movements and other items typically used to portray traffic movement. In order for traffic monitoring data to be assessed properly, information on how the data were collected, edited, summarized and reported must be provided. This obligation…

In the Transportation Recall Enhancement, Accountability and Documentation Act, the U.S. Congress indicated the need for an aging test on light vehicle tires. Since no industry or government standard addressed this subject, ASTM Committee F09 on Tires developed ASTM F2838 , Practice for Accelerated Laboratory Aging of Radial Passenger Car and Light Truck Tire Through Load Range E for the…

The purpose of a laboratory roadwheel test is to realistically evaluate tires for specific road conditions. To facilitate such tests, ASTM International Committee F09 on Tires has developed a practice to provide an industry standard for commercial radial truck-bus tire laboratory temperature algorithms. The algorithms equilibrate with flat surface (highway) operating temperatures to determine…
