How to fill out aashto t 304

How to fill out AASHTO T 304:

1. Start by gathering all the necessary materials and equipment for conducting the test, including a testing machine, sample containers, weighing scale, and testing sieves.
2. Prepare the sample by obtaining a representative portion of the material according to the specified method in AASHTO T 304. The sample should be obtained from a homogeneous stockpile or source.
3. Ensure that the sample is properly dried, as moisture content can affect the test results. The drying conditions should adhere to the guidelines outlined in AASHTO T 255 or any other relevant standard.
4. Once the sample is properly dried, it needs to be sieved using the appropriate sieves according to the specifications outlined in AASHTO T 304. The sieves should be clean and in good condition.
5. Carefully place the sample into the top sieve of the stack and securely fasten the sieve assembly onto the testing machine. Ensure that the sieves are properly arranged from largest to smallest size.
6. Set the testing machine to the specified sieving duration, typically 5 or 10 minutes, and start the test. The machine will carry out the necessary agitation required for the sieving process.
7. Once the sieving time is complete, carefully remove each sieve from the testing machine and separate the retained material from each sieve. Make sure to weigh both the retained material and the material passing through each sieve.
8. Record all the necessary data, including the weight of each sieve, the retained material, and the passing material. These measurements will be used to calculate the percentage of material passing through each sieve.
9. Clean and dry the sieves thoroughly after the test to prevent any cross-contamination for future use.
10. Finally, analyze the data obtained from the test to determine the gradation of the material according to the specifications outlined in AASHTO T 304.

Who needs AASHTO T 304:

1. Civil engineers, geotechnical engineers, and construction professionals involved in analyzing and characterizing the fine aggregate or sand used in various construction projects.
2. Testing laboratories, both private and public, that perform quality control tests on construction materials to ensure compliance with industry standards and specifications.
3. State and federal transportation agencies responsible for monitoring the quality and performance of sand and fine aggregate used in highway construction and maintenance projects.
