PART 2 PRODUCTS

2.1 HMA PAVEMENT

This work shall be performed for the new pavement placement of the proposed pavement as described below. This work shall be performed in accordance with the applicable articles in Section 1030 of the IDOT Standard Specifictions, the construction details, and as directed by the Engineer.

2.2 SUB-BASE

A coating of Asphalt for Prime Coat shall be applied to the surface of the sub-base.

2.3 STRIPING

This work shall be performed for the proposed pavement as described below.

This work shall be performed in accordance with the applicable articles in Section 808 of the IDOT Standard Specifications, the construction details, and as directed by the Engineer. Pavement striping shall be 4 inch wide Thermoplastic Pavement Markings.

PART 3 EXECUTION

3.1 PREPARATION

3.1.1 Excavation and Filling

Excavation and filling to establish elevation of subgrade is specified in Section 31 00 00 EARTHWORK.

3.2 CONSTRUCTION

The pavement shall be constructed to the lines and grades as shown on the drawings. All base course and pavement construction shall conform to the requirements as specified in the IDOT Division 300.

3.2.1 Striping

Allow bituminous pavement to cure for at least 21 days before paint is applied. Pavement shall be thoroughly clean and entirely free of loose sand, stones, dust, oil, grease, water, and other substances that will be deleterious to the paint or will adversely affect the adhesion of the paint. Do not apply paint during high wind (over 15 miles per hour) or high humidity (over 70 percent). Apply paint only when ambient temperature is 40 degrees F or above and rising but not more than 95 degrees F.

Dimensions and arrangement of striping shall be as indicated. Apply paint to a wet film thickness of 0.015 inch by means of conventional traffic line striping equipment. Traffic shall not be permitted to use the painted areas for a minimum of 30 minutes after painting of lines has been completed.

3.3 FIELD QUALITY CONTROL

The Contractor shall establish and maintain a quality control system for work under this section to assure compliance with contract requrements and maintain recoreds of his quality control for all construction operations including, by not limited to, the following:

SECTION 32 10 00 Page 4

(1) Quality of materials,

(2) Surface preparation,

(3) Placement thickness and compaction

(4) Lines and grades, and

(5) Drainage.

A copy of these records and test, as well as the records of corrective action taken, shall be furnished to the government as directed by the Contracting Officer. Quality control tests and inspections shall be performed by and at the expense of the Contractor.

Tests: All samples of materials shall be supplied by the Contractor at his expense, and all tests necessary to determine conformance with the requirements specified herein will be performed without costs to the government. All materials shall be approved by the Contracting Officer prior to use. The sources from which the materials are to be obtained shall be selected in advance of the time when the materials will be required in the work. Additional samples shall be furnished during construction, upon request. Samples cut from the completed work, when required by the Contracting Officer for testing purposes, shall be replaced with new mixture and refinished. Furnishing test samples and replacing the areas with new material will be considered as incidental to the construction.

Specimens shall be cut by the Contractor with a core drill. The diameter of the specimen shall in no case be less than 3-7/8 inches nor more than 4 inches.

Sample shall be taken by Contractor as specified herein. Contractor shall replace pavement where sample cores have been removed. Submit 2 pavement cores when using the in-place nuclear density method.

3.3.1 Sample and Core Identification

Place each sample and core in a container and securely seal to prevent loss of material. Tag each sample for identification. Tag shall contain the following information:

a. Contract No.

b. Sample No.

c. Quantity

d. Date of Sample

e. Sample Description

f. Source/Location/Stations Placed/depth below the finish grade

g. Intended Use

h. Thicknesses of various lifts placed

SECTION 32 10 00 Page 5

3.3.2 Testing

3.3.2.1 Bituminous Mix Testing

Take two samples per day per mix type at plant or from truck. Test uncompacted mix for extraction in accordance with ASTM D 2172 and sieve analysis in accordance with AASHTO T 30. Test samples for stability and flow in accordance with ASTM D 1559. When two consecutive tests fail to meet requirements of specifications, cease placement operations and test a new trial batch prior to resumption of placement operations. Submit 2 per day of each mix type. When two tests on uncompacted mix fail submit new trial batch for approval.

3.3.2.2 Testing of Pavement Course

a. Density: Determine density of pavement by testing cores obtained from the binder and wearing course in accordance with AASHTO T 230.

Take three cores at location designated by Contracting Officer for each 200 tons, or fraction thereof, of asphalt placed. Deliver cores undisturbed and undamaged to laboratory and provide test results within 48 hours of each day placement of paving materials.

b. Thickness: Determine thickness of the binder and wearing course from cores taken for density test.

c. Straightedge Test: Test compacted surface of binder course and wearing course with a straightedge as work progresses. Apply straightedge parallel with and at right angles to center line after final rolling. Variations in the binder course surface shall not be more than 1/4 inches from the lower edge of the 10 foot straightedge; variations in wearing course surface shall not be more than 1/4 from the lower edge of the 10 foot straightedge.

Pavement showing irregularities greater than that specified shall be corrected as directed by Contracting Officer.

d. Drainage: Pavement shall not permit ponding of water, and shall be sloped to drain as shown on the plans.

3.3.2.3 Alternate Testing Method for Pavement Courses

At Contractor's option the following in-place testing method may be used to determine density and thickness in lieu of testing specified above.

Frequency of testing shall be the same. When in-place nuclear method to determine density is used, take two pavement cores at locations designated by Contracting Officer and turn over to Government to verify pavement thickness.

a. Density: Determine density of pavement by in-place testing using Nuclear Method in accordance with ASTM D 2950.

b. Thickness: Determine thickness of finished pavement by use of following equation:

t= ___W____ 0.75d

Where t= pavement thickness, in inches.

W= average weight per square yard of mixture actually used in work.

d= compacted density as measured by nuclear density device.
