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

Three-dimensional laser scanning is a maturing technology that holds great promise for capturing highly accurate information about an object or scene by collecting millions of dense measurements very quickly. ASTM International Committee E57 on 3D Imaging Systems is developing new standards for this technology, including ASTM E2807 , Specification for 3D Imaging Data Exchange, Version 1.0. ASTM…

A need for a scientifically based procedure to identify equivalent test severity conditions between a 1.707-m diameter laboratory roadwheel surface and a flat or highway surface for radial pneumatic light truck tires has led to the development and approval of a new ASTM International standard. The new standard, ASTM F2869 , Practice for Radial Light Truck Tires to Establish Equivalent Test…

A new task group within ASTM Committee E57 on 3D Imaging Systems plans to develop standards on position and orientation (pose) determination that could help increase productivity and enhance the global competitiveness of the U.S. manufacturing industry. The task group, under the jurisdiction of Subcommittee E57.02 on Test Methods, is currently working on its first proposed new standard, ASTM…

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…

A new ASTM subcommittee seeks to acknowledge the ongoing advances being made in the field of nanostructured inorganic coatings. B08.16 on Nanostructured Coatings, part of ASTM International Committee B08 on Metallic and Inorganic Coatings, is currently developing its first proposed standard, ASTM WK29468 , Specification for Galvanic Protection of Steel Using a Nanostructured Coating of 95 % Zinc…

Three-dimensional laser scanning is an emerging technology that holds great promise for capturing dimensionally accurate information about an object or scene by collecting millions of dense measurements very quickly. ASTM International Committee E57 on 3D Imaging Systems is developing new standards for this technology, including ASTM E2761, Specification for 3D Imaging Data Exchange. ASTM E2761,…

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…

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…
