Patients with blockages in their coronary vasculature have historically been treated with permanent metallic stents, metal mesh tubes that open clogged blood vessels, restore blood flow and keep the vessel open over time. Certain patients can now be treated with an absorbable stent, otherwise known as a vascular scaffold, available in international markets. Absorbable stents are designed to open…, ASTM Committee F04 Next Meeting:, May 6-9, 2014, May Committee Week, Toronto, Ontario, Canada, Technical Contact:, Julia Fox, Ph.D., Abbott Vascular, Santa Clara, Calif., Phone: 408-845-0719; julia.fox@av.abbott.com , ASTM Staff Contact:, Pat Picariello, Phone: 610-832-9720; ppicariello@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9561

An ASTM International symposium on metal-on-metal total hip replacement devices held in May 2012 identified unmet standardization needs. One such need was for a standard that deals with the collection and analysis of explanted hip implants in order to understand their in-vivo performance. In addition, the U.S. Food and Drug Administration Order 522 mandates orthopaedic companies to carry out…, ASTM Committee F04 Next Meeting:, May 6-9, 2014, May Committee Week, Toronto, Ontario, Canada, Technical Contact:, Richard Underwood, Ph.D., Exponent, Philadelphia, Pa., Phone: 215-594-8800, ext. 8875; runderwood@exponent.com , ASTM Staff Contact:, Pat Picariello, Phone: 610-832-9720; ppicariello@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9524

Roller-compacted concrete is a stiff, dry concrete mix that has a low paste content and is placed and compacted using a roller, usually a 10-ton vibratory roller. In pavement construction, the process is similar to that for an asphalt pavement. RCC mixes are used in a variety of heavy-duty applications at logging yards, loading docks, intermodal port facilities, large parking areas and dams.…, ASTM WK33682, Test Method for Preparation, Compaction and Density Determination of Roller-Compacted Concrete Specimens by Means of the Gyratory Compactor, According to Stacy G. Williams, Ph.D., director, Center for Training Transportation Professionals at the University of Arkansas, and a C09.45 member, notes that the Superpave gyratory compactor was developed during the 1980s as a means to provide a laboratory simulation of the compactive effort imparted by rollers on an asphalt mat. Roller-compacted concrete is compacted using the same type of…, ASTM WK41101, Practice for Molding Roller-Compacted Concrete in Beam Molds Using a Vibrating Hammer, Once approved, ASTM WK41101 will be used to consolidate RCC into beam molds with established flexural strengths. This is important because RCC is gaining use as a pavement for roads, shoulders and streets and all pavements need flexural strength data for design purposes. , ASTM WK42461, Test Method for Density (Unit Weight) and Air Content (Pressure Method) of Freshly Mixed Roller-Compacted Concrete, ASTM WK42461 covers the determination of density and air content of freshly mixed concrete. WK42461 will be used in the design of roller-compacted concrete mixtures and to aid in controlling the quality of those mixtures during RCC construction.
