3.7 INSTALLATION TOLERANCES

A. Pavement Thickness: Compact each course to produce thickness indicated within the following tolerances:

1. Binder Course and Surface Course: Plus or minus ¼ inch when the total nominal thickness indicated on the plans is 4 inches or less. Plus or minus ½ inch when the total nominal thickness is over 4 inches but not more than 8 inches. When the asphalt mixture is placed on newly constructed subbase material, an additional tolerance of ½ inch will be allowed both in the nominal thickness of the course placed directly on the subbase and the total pavement thickness.

B. Pavement Surface Smoothness: Compact each course to produce surface smoothness within the following tolerances as determined by using a 10-foot straightedge applied transversely or longitudinally to paved areas:

1. Binder Course: 1/4 inch.

2. Surface Course: 1/4 inch

3. Crowned Surfaces: Test with crowned template centered and at right angle to crown.

Maximum allowable variance from template is 1/4 inch.

4. Variations exceeding ¼ inch will be appropriately corrected or the pavement be removed and replaced at no additional cost to the State.

3.8 FIELD QUALITY CONTROL

A. Testing Agency: Contractor shall engage a qualified testing agency to perform tests and inspections.

B. Thickness: In-place compacted thickness of asphalt courses will be determined in accordance with ASTM D3549.

C. Surface Smoothness: Finished surface of each asphalt course will be tested for compliance with smoothness tolerances.

D. Density Testing: Testing agency will take samples of uncompacted paving mixtures and compacted pavement in accordance with AASHTO T 168.

1. Reference maximum theoretical density will be determined by averaging results from four samples of asphalt-paving mixture delivered daily to site, prepared in accordance with ASTM D2041, and compacted in accordance with job-mix specifications.

2. Density of compacted pavement will be determined by testing core samples in accordance with ASTM D1188 or ASTM D2726.

ASTM D2726.

E. Replace and compact asphalt where core tests were taken.

F. Remove and replace or install additional asphalt where test results or measurements indicate that it does not comply with specified requirements.
