A proposed new standard being developed by ASTM International Committee E17 on Vehicle-Pavement Systems will be the first to describe how truth-in-data should be applied to traffic monitoring data collection, summarization and reporting. WK25280 , Practice for Highway Traffic Monitoring Truth-in-Data, is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Current traffic…

Being able to compile and interpret data on how traffic turns through an intersection could have an impact on future environmental and safety decisions regarding intersection geometry and traffic control. However, until recently no standard has existed to properly obtain and use this data. Now, ASTM International Committee E17 on Vehicle-Pavement Systems has approved E2667 , Practice for…

When fasteners penetrate roofing or waterproofing products as a planned part of installation, it is expected in some cases that the product will resist water migration at the point of penetration. A new ASTM International standard, D7349 , Test Method for Determining the Capability of Roofing and Waterproofing Materials to Seal Around Fasteners, addresses this situation. ASTM D7349 was developed…

Modified bitumen products have been in use since the mid-1970s, and represent a substantial percentage of the commercial asphalt roofs installed throughout North America. A new ASTM International standard addresses the use of cold process adhesives in modified bitumen roofing systems. ASTM D7379 , Test Methods for Strength of Modified Bitumen Sheet Material Laps Using Cold Process Adhesive, was…

Drawing on the best practices of the U.S. Federal Highway Administration and the states, ASTM International Committee E17 on Vehicle-Pavement Systems has developed a new standard, E 2561 , Practice for Installation of Inductive Loop Detectors. E 2561 is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Inductive loop detectors are installed in sawed slots in roadway pavement…

Airport operators, military pavement maintenance personnel, transportation regulatory agencies and state highway departments will all benefit from the approval of a new ASTM standard for measuring skid resistance. The standard, E 2340 , Test Method for Measuring the Skid Resistance of Pavements and Other Trafficked Surfaces Using a Continuous Reading, Fixed-Slip Technique, was developed by…

Two new standards developed by ASTM International Committee E17 on Vehicle Pavement Systems will provide uniform specification and test criteria for agencies and manufacturers that deal with traffic monitoring devices. The new standards, which are both under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring, are E 2300 , Specification for Highway Traffic Monitoring Devices, and E 2532…

A more efficient method to take asphalt pavement layer temperatures is the subject of a new standard developed by Subcommittee E17.41 on Pavement Management. The document, D 7228 , Test Method for Prediction of Asphalt-Bound Pavement Layer Temperatures, details surface temperature measurement and is based on temperature relationships in the Federal Highway Administration Long Term Pavement…

Many state departments of transportation are collecting traffic data in real time and using it to manage traffic or provide travel information, as part of intelligent transportation systems. Some agencies save and archive this data after its initial real-time use and make it available to other data users, who often know little about how the data was collected or even what is contained in the data…

A process hazard analysis prior to the startup of a chemical processing facility is essential to prevent catastrophic incidents due to thermal runaway reactions. A proposed new ASTM standard, WK9584, Guide for Assessing Potential Hazards of Synthesis Reactions Using Reaction Calorimetry, will help to standardize how the results from reaction calorimetry experiments are used in a process hazard…
