20 APPENDIX A- INSTRUCTIONS AND DATA SHEET FOR INTERLABORATORY STUDY
21 Instructions to Laboratories for Testing AASHTO T265 Specimens Dear laboratories, Thank you for participating in the AASHTO T265 interlaboratory study. Please follow the instructions below to ensure that all the required data for precision-estimates determination will be collected. 1. Please check the boxes to make sure that you have received all the specimens: ï· Box 1 of 3 is marked as Fine Soil-Aggregate Blend, which contains 9 bottles of Fine blend with clay (FC) and 9 bottles of fine blend with silt (FS). ï· Box 2 of 3 is marked as Coarse Soil-Aggregate Blend with Clay (CC), which contains 9 bottles. ï· Box 3 of 3 is marked as Coarse Soil-Aggregate Blend with Silt (CS), which contains 9 bottles. 2. Follow Section 5 of AASHTO T265 to determine the moisture contents of specimens. Use the entire content of each bottle for one moisture content determination. Please note that it is important to scrape out everything out of a bottle for each moisture content determination. 3. Record the required weights to the nearest 0.01 g in the attached worksheet. An electronic file of the data sheet has been sent via email. Please let me know if you have not received it. The file has two different sheets, one sheet for recording the data for the coarse blend and another sheet for recording the data for the fine blend. 4. Calculate moisture content of each specimen as a percentage of the mass of the water removed to the mass of the solid particles accordance to Section 6 of AASHTO T265. Report percent moisture content to the nearest 0.01 percent. 5. Please return the data by May 22, 2009. Please call at (301) 975-2112 or send email to hazari@amrl.net if you have any questions.
