In many testing laboratories, it can be necessary to qualify a new test method, instrument or lab itself with respect to one or more performance characteristics. One such key characteristic is bias, or mutual agreement of average test results run on the same material. A proposed ASTM standard will aid in the determination of bias equivalency. ASTM WK37659 , Guide for Testing for Bias Equivalency…

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…

Since the appearance of the first California-type models around 1940, the profilograph has been a popular device used for quality control in the construction of pavements. Both roadway and airfield landing agencies have adopted roughness indexes computed from profilograph-derived measurements as a level of construction quality. Emerging high-speed inertial profilers can now quickly collect…
