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…

A recent revision to ASTM standard F1148 , Consumer Safety Performance Specification for Home Playground Equipment, reflects the purpose of the standard, which is to reduce the likelihood of life-threatening or debilitating injuries. The revised version of ASTM F1148 no longer allows home playground sets designed with swings that attach to an upper body component (such as “monkey bars”).…

Test for Solubility of Asphalt Materials in n-Propyl Bromide A new ASTM International standard on solubility of asphalt will provide an alternative for a solvent that has been banned as an ozone depleter by the Kyoto Protocol, an international environmental treaty with the goal of stabilizing greenhouse gas concentrations that may help minimize global warming. The new standard, ASTM D7553 , Test…

ASTM International Committee F15 on Consumer Products is currently developing a proposed new standard at the request of the Consumer Product Safety Commission. The proposed standard, WK20641 , Specification for Cautionary Labeling of Inflatable Air Mattresses, is under the jurisdiction of Subcommittee F15.63 on Inflatable Air Mattresses. Since 2002, there have been 16 fatalities (many of them…

Many factors, such as traffic, drainage, structure and climatic variations, impact the field performance of asphalt concrete. However, asphalt concrete performance has been more accurately predicted when laboratory material properties are known, so ASTM International Committee D04 on Road and Paving Materials has approved a new standard, ASTM D7460 , Test Method for Determining Fatigue Failure of…

Current methods for determining bulk specific gravity of aggregate are often time-consuming and not ideal for quality control checks during construction. However, a new ASTM International standard provides a fast method for determining the consistency of aggregate properties that are used in asphalt and concrete mixtures. Committee D04 on Road and Paving Materials has approved ASTM D7370…
