904.06 B Borrow The material used for special filling shall be of acceptable quality, free from large
or frozen lumps, wood, or other extraneous matter and shall be known as B borrow. It shall consist of suitable sand, gravel, or crushed stone ACBF, GBF, or other approved material. The material shall contain no more than 10% passing the No. 200 (75 μm) sieve and shall be otherwise suitably graded . The ratio of the fraction passing the No. 370 200 (75 μm) sieve to the fraction retained on the No. 30 (600 μm) sieve shall not exceed one-fifth. The use of an essentially one-size material will not be allowed unless approved. B borrow containing greater than 3% by dry weight organic material will not be allowed. Sieve analysis and organic material will be performed in accordance with AASHTO T 11 and AASHTO T 267.
904.07 Exceptions to AASHTO Standard Methods 380
a.Exceptions to AASHTO R 90 Stockpile sampling shall be in accordance with ITM 207, unless otherwise approved.
b.Exceptions to AASHTO T 11, T 27, and T 37 1. When tests are performed in the field where ovens are not available, test samples may be dried in suitable containers over open flame or electric hot plates with sufficient stirring to prevent overheating, then cooled to constant weight. 390
2.The balance shall be a Class G2 general purpose balance in accordance with AASHTO M 231. 904.07 1015 (c) Exceptions to AASHTO T 27 for Coarse Aggregates The size of test samples for coarse aggregate shall be as follows: Aggregate Size Mass of T e s t S a m p l e No. 2 ............................................... 11.3 kg min. 400 No. 5, 8, 43, 53, 73, and 91 ............ 6.0 - 8.0 kg No. 9 ............................................... 4.0 - 6.0 kg Structure Backfill 2 in. ......................................... 11.3 kg min. 1 1/2 in. and 1 in. .................... 6.0 - 8.0 kg 1/2 in. ...................................... 4.0 - 6.0 kg No. 4 and No. 30 ..................... 300 g
d.Exceptions to AASHTO T 85 The in-water weight shall be determined following the 15 h soaking period prior 410 to determining the SSD weight. (e) Exceptions to AASHTO T 103 and T 104
1.Counting the number of individual particles coarser than the 3/4 in. (19.0 mm) sieve will not be required.
2.For testing ledge rock, the ledge samples shall be crushed to obtain test samples for the designated increments passing the 1 1/2 in. (37.5 mm) sieve and retained on the No. 4 (4.75 mm) 420 sieve. The factors used to calcu late the weighted average loss are 30%, 40%, and 30% of the 1 1/2 in. (37.5 mm) ޤ3/4 in. (19.0 mm), 3/4 in. (19.0 mm) ޤ3/8 in. (9.5 mm), and 3/8 in. (9.5 mm) ޤNo. 4 (4.75 mm) increments, respectively.
3.In the case of ledge rock, modify sections 3.3 and 6.2 of AASHTO T 103 and AASHTO T 104 respectively. When the sample received is deficient in material of a component size of any test portion, that material will be supplemented with the available component size to provide the test portion. 430
4.Modify section 8 of AASHTO T 103 and section 10 of AASHTO T 104. For materials designated as a coarse aggregate, the weighted loss will be calculated considering the material retained on the No. 4 (4.75 mm) sieve as 100% of the sample, and only the total weighted loss reported. In AASHTO T 104 sections 10.1.3.2 and 10.1.3.3 shall not apply, and unless otherwise noted only new solution will be used. 440 904.07
