Brief summary of activities to ensure all attendees up to speed II. If you need to print pages from this book, we recommend downloading it as a PDF. Other technologies, in addition to various types of fibers, may be used in this item if test data and field performance demonstrate these specifications are met. These methods cover the reduction of large samples of aggregate to the appropriate size for testing employing techniques that are intended to minimize variations in measured characteristics between the test samples so selected and the large sample. Not required when crumb rubber is used. Acceptance is usually below 4. Melinda McGrath, P.
The high temperature helps ensure Follow instructions on the reference material certificate with the quantitative recovery of carbon from cokes. The infrared respect to storage of the reference material and use of assigned absorption detection system shall include provisions for evalu- values.
Use only those carbon, hydrogen and nitrogen values ating the response in a manner that correlates accurately with that have an assigned uncertainty or are traceable to a value the carbon dioxide present in the dry combustion gases. Follow with an assigned uncertainty. None of the calibrants yields percent nitrogen values within the ranges expected for coal. For this reason reference material RM coal is used to check the 6. Reagents acceptability of nitrogen results.
Unless otherwise indicated, it is intended that 7. Preparation of Analysis Sample all reagents shall conform to the specifications of the Commit- 7. Coal samples shall be where such specifications are available. For suggestions on the testing of reagents not listed by the American Chemical Society, see Analar Standards for Laboratory rameters meet the specifications in the instrument operating Chemicals, BDH Ltd.
Verify the condition and quantities of all chemicals and National Formulary, U.
Pharmaceutical Convention, Inc. Before beginning production of a new HMA mix, a successful plant trial batch shall be performed for that mix and the results forwarded on forms provided by the Engineer. Grading designations are related to the average seven-day maximum pavement design temperature, and traffic loading. To account for traffic volume and speed or both, adjustments should be made to the selected binder in accordance with AASHTO M requirements.
However the conversion of the current PG grades, bumped for traffic, to the H, V, E grades should be calibrated locally.
For most modified asphalt binders, we recommend periodic agitation of one hour of agitation daily. The high temperature performance grade HT-PG was also measured and reported at each of these conditions. As such, we transitioned to M in the first two years by allowing both M and M grading.
Binder from all local suppliers was tested via these test methods. October Waive Jnr Difference. Published by AASHTO on January 1, This standard practice covers the accelerated aging oxidation of asphalt binders by means of pressurized air and elevated temperature.
Federal Highway Administration expert task groups, cooperate to improve both sets of standards and keep them in sync, according to Kluttz.
J nrdiff is an extremely variable parameter and does not accurately describe stress sensitivity. All of the included tests are performed at one temperature. Our technicians use state-of-the-art equipment and technology to test PG binders, emulsions and cutback binders for contractors, agencies and refineries.
An example QC Plan is available upon request. Enter now! The Department has some internal data from the past few years. The Contractor shall submit a Certified Test Report showing the results of the testing demonstrating the binder grade. M M M M M Gaddie Shamrock Columbia Plant 1-Mod. Subsection Change 5.

The recent national research indicated that the existing AASHTO M protocol does not accurately characterize the PG binders modified with either polymers or other modifiers. Standardized test methods in increasingly common use are adequate to characterize HiMAmixtures for the purpose of pavement design.
B:I need a copy of the agenda. Also, may I suggest sth.?
I know we have many points to review today, but would it be possible to limit our meeting time to finish before 4 o'clock? Many of us still have a mountain of work to do before the day's end.
