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…

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…

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…

ASTM International Subcommittee A01.05 on Steel Reinforcement has made a significant revision to ASTM A706/A706M , Specification for Low-Alloy Steel Deformed and Plain Bars for Concrete Reinforcement. A higher yield strength level, namely Grade 80 [550], has been added to the standard. The term “grade” relates to minimum yield strength in units of “kps/in.2 (megapascals),” i.e., “Grade 80 [550]”…

A rim slip performance test for tires that has been done at the Nevada Automotive Test Center for more than 20 years has now become an ASTM International standard. ASTM F2803 , Test Method for Evaluating Rim Slip Performance of Tires and Wheels, was developed by Subcommittee F09.20 on Vehicular Testing, part of ASTM International Committee F09 on Tires. Rim slip occurs when tire and wheel…, ASTM Committee F09 Next Meeting:, April 21-22, April committee week, St. Louis, Mo., Technical Contact:, Jason Whiteley, Nevada Automotive Test Center, Silver Springs, Nev., Phone: 775-629-2000, jwhiteley@natc-ht.com, ASTM Staff Contact:, Rick Lake, Phone: 610-832-9689; rlake@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8494/Feb2010

ASTM Committee A01 on Steel, Stainless Steel and Related Alloys has now published a versatile new standard, A1064/A1064M , Specification for Steel Wire and Welded Wire Reinforcement, Plain and Deformed, for Concrete. The new standard is under the jurisdiction of Subcommittee A01.05 on Steel Reinforcement. Ted Mize, P.E., senior engineer, Ivy Steel & Wire, and an A01.05 member, notes that ASTM…, ASTM Committee A01 Next Meeting:, May 17-20, May Committee Week, St. Louis, Mo., Technical Contact:, Ted Mize, Ivy Steel & Wire, Concord, Calif., Phone: 925-685-9141, tmize@ivysteel.com, ASTM Staff Contact:, George Luciw, Phone: 610-832-9710, gluciw@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #844 3/Dec2009

A proposed new standard being developed by ASTM International Committee E17 on Vehicle-Pavement Systems will be the first to describe how truth-in-data should be applied to traffic monitoring data collection, summarization and reporting. WK25280 , Practice for Highway Traffic Monitoring Truth-in-Data, is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Current traffic…
