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…

An effort currently under way by the U.S. Federal Highway Administration to set national standards for minimum maintained retroreflectivity levels for pavement markings has illustrated the need for a practical protocol to measure such levels. In response to this need, ASTM International Committee D04 on Road and Paving has developed ASTM D7585/D7585M , Practice for Evaluating Retroreflective…

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…

The need for a standard test method that would allow the determination of the complex shear modulus of bituminous mixtures using relatively inexpensive laboratory equipment has led to the development of a new ASTM International standard, ASTM D7552 , Test Method for Determining the Complex Shear Modulus (G*) of Bituminous Mixtures Using Dynamic Shear Rheometer. According to Gerald Reinke,…, ASTM Committee D04 Next Meeting:, June 8-10, June committee week, St. Louis, Mo.

More frequent worldwide use of asphalt-rubber binders in road building has increased the need for rotational viscotesters, which are used to ensure proper quality control and assurance. While an appropriate standard for viscotesters does not currently exist, a proposed new ASTM standard will answer this need. The proposed standard, WK25108 , Test Method for Measurement of Apparent Viscosity of…
