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.

Halon 1211 is employed in hand-held fire extinguishers on civilian aircraft. A new ASTM International standard will be used to test Halon 1211 to ensure that the product will provide the required level of fire protection and is free of harmful impurities that could affect its safety in use. ASTM D7673 , Specification for Halon 1211, Bromochlorodifluoromethane (CF2BrCl), was developed by…, ASTM Committee D26 Next Meeting:, June 15, 2011, June Committee Week, Anaheim, Calif., Technical Contact:, Mark L.

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…

Being able to compile and interpret data on how traffic turns through an intersection could have an impact on future environmental and safety decisions regarding intersection geometry and traffic control. However, until recently no standard has existed to properly obtain and use this data. Now, ASTM International Committee E17 on Vehicle-Pavement Systems has approved E2667 , Practice for…
