The abrasiveness of rock plays a crucial role in the performance of any mechanical excavation machines because overall costs are affected by the rate of cutting tool replacement and/or repair and machine downtime. The need for a standard that assists the civil and mining industries in quantifying rock abrasiveness properly and uniformly has been answered by a new ASTM International standard.…

A proposed new ASTM standard is an important step in guiding federal, state and local highway agencies, contractors, material suppliers and consultants on the sustainable use of recycled asphalt pavement. ASTM WK26824 , Specifications for Recycled Asphalt Pavement Materials for Base or Subbase for Highway or Airports, is being developed by Subcommittee D18.14 on Geotechnics of Sustainable…, ASTM Committee D18 Next Meeting:, June 6-8, June committee week, St. Louis, Mo., Technical Contact:, Haifang Wen, Washington State University, Pullman Wash., Phone: 608-262-1777; haifang_wen@wsu.edu, ASTM Staff Contact:, Robert Morgan, Phone: 610-832-9732; rmorgan@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8493/Feb2010

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]”…

Wet and dry density of soils are important values for geotechnical engineers in determining over-burden stresses, void ratios, maximum compaction and percent compaction of soils. Density value can also aid in the evaluation of soil strength and sensitivity. While reporting on soil density has been part of routine laboratory testing for years, there have been no standards that outlined procedures…

Responding to requests from industry, ASTM International Committee D18 on Soil and Rock is developing a proposed new standard for measuring rock abrasivity, which will aid mechanical excavation projects in several ways. The proposed standard, ASTM WK22313 , Test Method for Laboratory Determination of Abrasivity of Rock Using the CERCHAR Method, is under the jurisdiction of Subcommittee D18.12 on…

A type of testing that can aid in predicting soil and foundation response to seismic and manmade disturbances is covered in a proposed new ASTM International standard. The proposed standard, WK23118 , Test Method for Determination of Shear Wave Velocity by Bender Element, is being developed by Subcommittee D18.09 on Cyclic and Dynamic Properties of Soils, part of ASTM International Committee D18…

A new ASTM International standard will serve as a guide for manufacturers and laboratories that make and test steel products according to standards using the SI system of units. The new standard, ASTM A1058 , Test Methods for Mechanical Testing of Steel Products—Metric, arose from a need for a stand-alone metric steel testing standard, according to Lester Burgess, director of quality, TSP/U.S.…
