An extensively revised standard and a proposed new standard are among the latest activities pursued by ASTM International Committee D18 on Soil and Rock. Subcommittee D18.11 on Deep Foundations has completed revisions to D 1143 , Test Method for Deep Foundations Under Static Axial Compressive Load, while Subcommittee D18.25 on Erosion and Sediment Control Technology is now working on proposed new…, ASTM D 1143, Test Method for Deep Foundations Under Static Axial Compressive Load, D 1143 covers procedures for testing vertical or inclined deep foundations individually or in groups to determine the axial deflection in response to a static axial compressive load. Subcommittee D18.11 has recently approved an extensive revision of D 1143 that reflects the latest technology used for these purposes. The following are the biggest changes to D 1143, according to Paul Bullock,…, WK13229, Test Method for Determination of Hydraulically Applied Fiber Matrix Performance in Protecting Hill Slopes from Rainfall-Induced Erosion, Subcommittee D18.25 is seeking participation in the ongoing development of WK13229 , particularly from testing laboratories and tackifier manufacturers/importers. WK13229 covers the guidelines, requirements and procedures for evaluating the ability of hydraulically applied fiber matrix to protect hill slopes from rainfall-induced erosion. For this protection to happen effectively, the fiber…

Two new standards have recently been approved by ASTM International Committee D04 on Road and Paving Materials. The standards, both of which are under the jurisdiction of Subcommittee D04.26 on Fundamental/Mechanistic Tests, are D 6931 , Test Method for Indirect Tensile (IDT) Strength of Bituminous Mixtures, and D 7312 , Test Method for Determining the Permanent Shear Strain and Complex Shear…, ASTM D 6931, Test Method for Indirect Tensile (IDT) Strength of Bituminous Mixtures, The withdrawal of D 4123 , Test Method for Indirect Tension Test for Resilient Modulus of Bituminous Mixtures, led to the development of D 6931 , since D 4123 contained a description of an indirect tensile strength test that was referred to in several other standards. It was decided to develop this test into a completely separate standard, D 6931, to stand on its own merit as a method that…, ASTM D 7312, Test Method for Determining the Permanent Shear Strain and Complex Shear Modulus of Asphalt Mixtures Using the Superpave Shear Tester (SST), According to Rebecca McDaniel, technical director, North Central Superpave Center, and leader of the D 7312 task group, Superpave is a system for designing asphalt mixtures to ensure that the right asphalt binder and aggregate structure is used for the traffic and climate where it will be placed on the road. To facilitate the implementation of Superpave, the Federal Highway Administration…

ASTM International Committee D18 on Soil and Rock has recently approved a new standard, D 6938 , Test Methods for In-Place Density and Water Content of Soil and Soil-Aggregate by Nuclear Methods (Shallow Depth). The new standard, which is under the jurisdiction of Subcommittee D18.08 on Special and Construction Control Tests, consolidates the information contained in two other D18.08 standards, D…

A proposed new standard currently being developed by ASTM International Committee D18 on Soil and Rock will be a useful tool in assuring that an important technique for describing volatile organic contaminants in subsurface soils and ground water is properly performed in the field. The proposed standard, WK13569 , Practice for Direct Push Technology for Volatile Contaminant Logging with the…

Soil and rock monitoring programs that use inclinometer probes often run for several years. Normal wear and tear can degrade the probe’s ability to produce useful surveys, though this degradation can happen incrementally and may go unnoticed for some time. A new standard developed by ASTM International Committee D18 on Soil and Rock, D 7299 , Practice for Verifying Performance of a Vertical…

ASTM International Committee D18 on Soil and Rock invites all interested parties to participate in a new task group, D18.01.03 on Coal Mining Spatial Data Standards. The task group, which is being chaired by Joseph Ritchey, Pro2Serve-Professional Project Services, is under the jurisdiction of Subcommittee D18.01 on Surface and Subsurface Characterization. The new task group was established at…

ASTM International Committee D18 on Soil and Rock has developed a new standard that describes procedures for measuring in-place density and moisture of soil and soil-aggregate by the use of nuclear equipment. The new standard, D 6938 , Test Methods for In-Place Density and Water Content of Soil and Soil-Aggregate by Nuclear Methods (Shallow Depth), is under the jurisdiction of Subcommittee D18.08…

ASTM International Subcommittee G01.10 on Corrosion in Soils will be conducting two round robin testing procedures on Tuesday, November 14, from 9:00 a.m. to 3:00 p.m. during ASTM meetings in Atlanta, Ga. One round robin will be for the development of a new standard test method to measure the oxidation-reduction potential (redox) of soils, while the other will address precision and bias for the 4…

A new ASTM International standard will provide paving contactors and producers with instructions for preparing cold mix asphalt samples for testing. The standard, D 7229 , Test Method for Preparation and Determination of the Bulk Specific Gravity of Dense-Graded Cold Mix Asphalt (CMA) Specimens by Means of the Superpave Gyratory Compactor, was developed by Subcommittee D04.27 on Cold Mix Asphalts…
