1.4 DEFINITIONS

A. Lane-Leveling – Variable depth paving to correct minor rutting and longitudinal variations in the roadway.

1. Depth varies from the maximum aggregate size to the depth needed to correct variations.

B. Longitudinal Joint – Any new asphalt lift abutting an existing paving lift.

This includes joints created by echelon paving and new asphalt placed against a milled asphalt edge or to concrete elements.

C. Lot – The amount of Asphalt Mix placed in a single Production Day.

D. Minimum Lift Thickness – A compacted thickness at least three times greater than the nominal maximum aggregate size of the Asphalt Mixture except for lane leveling applications.

E. Minor Target Change – A change from the verified mix design gradation target on a maximum of two sieves with the following limitations.

1. The maximum change from the verified target gradation on the No.

8 or any coarser sieve is limited to 3 percent passing per sieve.

2. The maximum change from the verified target gradation on the No.

16 or No. 50 sieves is 2 percent passing per sieve.

3. The maximum change from the verified target gradation on the No.

200 sieve is 0.5 percent passing.

4. No target change may violate the mix design requirements in this section.

F. Overband – an 8-inch wide asphalt polymer treatment sealing the longitudinal joint.

G. Production Day – A 24-hour period in which Asphalt Mix is being placed.

H. Profile leveling - Variable depth paving to correct minor profile variations in the roadway.

I. Thin Overlay Pavement – New Asphalt Mix design for a placement lift less than 2 inches.

J. Warm Mix Asphalt (WMA) – Asphalt produced and placed at reduced temperatures using chemical admixtures to facilitate mixing and compaction.

1.6 ACCEPTANCE

A. The Engineer samples and tests the materials according to the MS&TR for specification 02741 and specification 02745 with the following modification.

1. One binder sample (set of 3 cans) minimum per each day’s mix production up to 2000 tons.

a. Take one additional binder sample (set of 3 cans), for each additional 2000 tons of mix, or portion thereof, in the same paving day.

02740S – 5 of 22

2. Take one additional mix sample for each 500 additional tons starting at 2000 mix tons per paving day.

B. Gradation and Asphalt Binder Content

1. The Engineer evaluates a lot on the test results of four or more samples, except when only three samples can be taken.

C. Density and Thickness

1. Obtain cores from the mat and longitudinal joint within two calendar days after the pavement is placed and according to UDOT Materials Manual of Instruction, Section 984.

a. The Engineer marks the coring locations for in-place mat density and longitudinal joint density cores.

1) The core must be taken within the 12-inch diameter marked location.

b. The Engineer witnesses the coring operation, and takes possession of the Department cores immediately, and begins testing the cores within 24 hours.

2. Density requirements

a. The target for in-place density for the top three inches of paving layer is 96.0 percent of Theoretical Maximum Specific Gravity.

1) Take the remaining lower portion of the core if it is two inches or more and test and report the density, percent of Theoretical Maximum Specific Gravity, for information only.

b. The target for in-place density for the longitudinal joint is

94.0 percent of the Theoretical Maximum Specific Gravity (G mm).

c. The target for in-place density is 96.0 percent of theoretical maximum specific gravity for thin overlay pavements.

1) Do not take longitudinal joint cores for thin overlay pavements

3. Thickness is evaluated with mat density cores. The thickness requirement may be waived when matching up to existing pavement, curb and gutter, or for pavement in or next to intersections.

a. The Engineer accepts a lot for thickness when:

1) The average thickness is not more than ½ inch greater or ¼ inch less than the total design thickness specified.

2) No individual core shows a deficient thickness of more than ⅜ inch.

02740S – 6 of 22

b. Excess thickness – The Engineer may allow excess thickness to remain in place or may order its removal.

1) The Department pays for 50 percent of the mix in excess of the +½ inch tolerance when that excess is allowed to remain in place.

c. Deficient thickness – Place additional material where lots or sublots are deficient in thickness. Place the material with the minimum lift thickness.

1) The Department pays for the material necessary to reach the specified thickness and for 50 percent of any additional material.

d. Thickness tolerances established above do not apply to leveling courses.

1) Check final surfaces in staged construction.

D. The Engineer calculates and applies one incentive or disincentive for the lowest dollar value for gradation and asphalt content, one incentive or disincentive for in-place mat density, and one incentive or disincentive for longitudinal joint density for each lot as follows:

1. The incentive or disincentive for gradation and asphalt binder and

In-place Mat Density and Longitudinal Joint Density will be calculated according to Table 1.

a. The incentive or disincentive will be based on the percent within limits (PT) computation using Tables 1, 2, 3, and 4.

b. The lowest single PT value combined for gradation (each of the sieves) and asphalt binder content for calculating the gradation and asphalt binder content incentive or disincentive will be used.

2. Tables 1, 2, 3, and 4 to determine PT for in-place mat density and longitudinal joint density will be used.

3. The in-place mat density must have a PT of at least 88 for there to be any incentives for longitudinal joint density or gradation and asphalt binder content.

4. The longitudinal joint density incentive/disincentive will be calculated based on the tonnage of asphalt mix placed adjacent to, and on the hot side of the longitudinal joint for each lift:

a. The incentive or disincentive will be calculated from the core densities taken from all abutting joints if the asphalt mix has a longitudinal joint on more than one side.

E. Refer to Section 02701 for smoothness requirements.

02740S – 7 of 22

F. Nonconforming lots:

1. If the PT for any individual gradation measurement is less than 52 percent as shown in Table 1.

Target Value (TV) The target values for gradation and asphalt binder content are given in the approved mix design. See this Section, Article 1.6 for density target values.

Average (AVE) The sum of the lot’s test results for a measured characteristic divided by the number of test results–the arithmetic mean.

Standard Deviations (s)

The square root of the value formed by summing the squared difference between the individual test results of a measured characteristic and AVE, divided by the number of test results minus one.

Upper Limit (UL) The value above the TV of each measured characteristic that defines the upper limit of acceptable production.

(Table 2)

Lower Limit (LL) The value below the TV of each measured characteristic that defines the lower limit of acceptable production.

(Table 2)

Upper Quality Index (QU) QU = (UL - AVE)/s

Lower Quality Index (QL) QL = (AVE - LL)/s

1. Verify by AASHTO T 255.

2. Adjust burners to avoid damage or soot contamination of the aggregate.

C. Treat aggregate with hydrated lime. Refer to Section 02746.

1. Method A or B

D. Coat with asphalt binder 100 percent of the particles passing the No. 4 sieve, and 98 percent of the particles retained on the No. 4 sieve.

1. Verify by AASHTO T 195.

2. Discontinue operation and make necessary corrections if material is not properly coated.

E. Maintain temperature of the Asphalt Mix between the limits identified on the Volumetric Mix Design Verification Letter for mixing and compacting.

1. Materials heated over the identified limits are non-conforming.

2. Remove all non-conforming materials.

3.2 ASPHALT MIX PLANT

A. Provide the following:

1. Positive means to determine the moisture content of aggregate on a daily basis.

2. Positive means to sample all material components.

3. Sensors to measure the temperature of the Asphalt Mix at discharge.

4. The ability to maintain discharge temperature of the mix according to the mix design.

B. Asphalt Binder Storage Tanks

1. Provide a positive means for separating and identifying asphalt grades when multiple products are used in mix production.

02740S – 17 of 22

2. Provide a positive means of determining the quantity of material in the tank at any time.

3. Provide…
