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…

A growing need to recycle millions of tires discarded annually is the impetus for the continued development of a proposed new ASTM International specification that provides standards for converting tires into an asphalt product. WK20240 , Specification for Performance Graded Tire Rubber-Modified Asphalt Binder is being developed by Subcommittee D04.40 on Asphalt Specifications, under the…

ASTM International Committee E31 on Healthcare Informatics notes the innovative use of the Continuity of Care Record within the Google Health application launched on May 20. Formally known as ASTM E2369 , Specification for Continuity of Care (CCR), the CCR standard is an XML-based format for access to, transport of and interoperable exchange of core summary health information. The CCR is intended…

ASTM International and AIIM, the international authority on Enterprise Content Management, have now published the Best Practices Guide – PDF Healthcare ( AIIM/ASTM BP-01-2008 ). This document describes a proposed, voluntary, industry-wide reference tool and guideline to describe the features and functionality of the Portable Document Format (PDF) for the healthcare industry. It is designed to…

The realization that concrete production is the result of a combination of several materials that are individually standardized, but which may interact in ways not governed by those standards, led ASTM International Committee C09 on Concrete and Concrete Aggregates to form Subcommittee C09.48 on Performance of Cementitious Materials and Admixture Combinations in 2004. The subcommittee has now…

A new ruling by the Federal Railroad Administration cites an ASTM standard as a means of making emergency exits from trains more visible to emergency personnel. The standard cited, D 4956 , Specification for Retroreflective Sheeting for Traffic Control, is under the jurisdiction of Subcommittee D04.38 on Highway Traffic Control Materials, part of ASTM International Committee D04 on Road and…

Applications are currently being accepted for the 2008 ASTM International Katharine and Bryant Mather Scholarship. Administered by ASTM International Committee C09 on Concrete and Concrete Aggregates, the scholarship applies to students pursuing degrees specializing in cement or concrete materials technology or concrete construction. Full-time undergraduate students completing their second/…

A proposed new standard being developed by ASTM International Committee C09 on Concrete and Concrete Aggregates will monitor clogging and long-term permeability of pervious pavements as well as determine if early sealing of the pavement has occurred during construction. This proposed standard, WK17606 , Test Method for Permeability of Pervious Concrete Pavements, is under the jurisdiction of…

All interested parties are invited to join in the activities of Subcommittee C09.49 on Pervious Concrete as it develops its first proposed standard, WK16885 , Test Method for Density and Void Content of Pervious Concrete. The subcommittee is under the jurisdiction of Committee C09 on Concrete and Concrete Aggregates. “WK16885 and forthcoming standards for pervious concrete arose from the need to…
