ASTM No. 57 Stone

The Curious Case of No. 57 Stone

May 12, 2014 Katherine Witt Articles, Forensics and Failures Comments Off

ASTM No. 57 Stone The American Society for Testing and Materials, or ASTM, No. 57 stone is often used as sub base fill material below road surfaces and buildings. It is a fragmented stone with angular edges and is regularly utilized as a drainage layer when used with geotextile fabric. Although the material is touted by many as "self-compacting," excess voids left from zero compactive effort in locations with little confinement may not eliminate the possibility of future settlement. What happens when the environment above the No. 57 stone causes it to settle?

[Editor] Read on for the answer to this interesting question in the case of settlement of a structure at the University of North Carolina at Chapel Hill. The contributed article by Katherine Witt describes how URETEK Mid-Atlantic used their high-density polyurethane resin to stabilize the No. 57 stone beneath a settled foundation as well as lift the surrounding slab back into place.

ASTM Standards November Update

November 26, 2008 rockman Standards and Codes Comments Off

American Society of Testing Materials Logo - ASTM November was a big month for updates to ASTM Standards…84 updates to be more specific. Several that caught my attention were D4546 One-Dimensional Swell or Settlement Potential, D7383 – Standard Test Methods for Axial Compressive Force Pulse (Rapid) Testing of Deep Foundations (a new standard), several standards that might affect shotcrete design and a large number of water testing standards. Read on for the list.

ASTM Updates May 2009

May 26, 2009 rockman Standards and Codes Comments Off

American Society of Testing Materials Logo - ASTM

In this month’s ASTM updates, there is a new standard for determining the laboratory density of soil specimens. Not having a standard for this item was a common problem for us in our practice. The lab would give us a density on ring samples by weiging, drying and weighing again using the known volume of the rings, but there was never any standard to go with it. Other updates this month include ones related to dimension stone, fiber reinforced concrete, sulfate content of soils, and calcium and magnesium content of water.
