l. Coarse Aggregate 7

1) Coarse aggregate stockpiles must have no more than 20 percent material 8 passing the No. 8 sieve. 9

2) Maximum aggregate size should not be over half of the proposed lift depth 10 to prevent particle on particle contact issues. 11

5) Allow 30 calendar days for the City to sample, test, and report results for 15 unlisted sources. 16

6) Class B aggregate meeting all other requirements in Table 2 may be 17 blended with a Class A aggregate in order to meet requirements for Class A 18 materials. 19

7) When blending Class A and B aggregates to meet a Class A requirement, 20 ensure that at least 50 percent by weight of the material retained on the No. 4 21 sieve comes from the Class A aggregate source. 22

8) Blend by volume if the bulk specific gravities of the Class A and B 23 aggregates differ by more than 0.300. 24

9) When blending, do not use Class C or D aggregates. 25

10) For blending purposes, coarse aggregate from RAP will be considered as 26

1) 3 consecutive tests on any individual sieve 31

2) 4 consecutive tests on any of the sieves 32

3) 2 consecutive tests on asphalt content 33

b. Begin production only when test results or other information indicate, to the 34 satisfaction of the City, that the next mixture produced will be within Table 11 35 tolerances. 36

3. Storage and Heating of Materials 37

a. Do not heat the asphalt binder above the temperatures specified in Section 38

2.2.A. or outside the manufacturer’s recommended values. 39

b. On a daily basis, provide the City with the records of asphalt binder and hot-40 mix asphalt discharge temperatures in accordance with Table 10. 41

c. Unless otherwise approved, do not store mixture for a period long enough to 42 affect the quality of the mixture, nor in any case longer than 12 hours. 43

4. Mixing and Discharge of Materials 44

a. Notify the City of the target discharge temperature and produce the mixture 45 within 25 degrees F of the target. 46

b. Monitor the temperature of the material in the truck before shipping to ensure 1 that it does not exceed the maximum production temperatures listed in Table 2

10. The City will not pay for or allow placement of any mixture produced 3 above the maximum production temperatures listed in Table 10. 4

c. Control the mixing time and temperature so that substantially all moisture is 5 removed from the mixture before discharging from the plant. 6
