AGGREGATE AND BASE COURSES

Section 301. — UNTREATED AGGREGATE COURSES

04/02/21– FP-14

Construction Requirements

301.03 General. Delete the text of this Subsection and substitute the following:

Prepare surfaces receiving aggregate courses according to Section 204 or 303 as applicable.

After a representative quantity of aggregate is produced, submit proposed target values for the appropriate sieve sizes along with a representative 400-pound sample at least 14 days before incorporating the aggregate into the work. Submit target values to the CO. Submit aggregate samples to the Vancouver Laboratory.

Set target values for base aggregate within the gradation ranges shown in Table 703-2 for the specified grading designation. List the percent passing for all sieve sizes shown in Table 703-2.

Target values for non-specification sieves are necessary for performing The Humphres Method of Granular Soils.

Remove and dispose of aggregate base grading D (temporary) when temporary widening is no longer needed. After removal, restore ditch lines and grades in areas of temporary widening as shown on the plans.

After placing the final 4-inch lift of new aggregate base, traffic should not be permitted before the chip seal construction is complete.

301.04 Mixing and Spreading. Delete the text of this Subsection and substitute the following:

Use the optimum moisture content from the Government-performed Humphres Test. Mix aggregate and water to obtain a uniform mixture with a moisture content within 1 percent of the optimum moisture content. Spread and shape uniform layers of mixtures on prepared surfaces.

Do not place mixtures in compacted layers thicker than 6 inches (150 millimeters). Compact each layer according to Subsection 301.05 before placing the next layer. Route hauling equipment uniformly over the full surface width to minimize rutting and uneven compaction.

If the calculated mean value for a tested sieve differs from the target value by more than the allowable deviation for that sieve, terminate placement and submit new target values with another aggregate sample to the Vancouver Laboratory for a new Humphres Test.

301.05 Compacting. Delete the text of the first paragraph and substitute the following:

The Government will determine the maximum density and optimum moisture according to the test procedures described on pages 92 to 98 of Highway Research Board Bulletin No. 319, dated 1962, The Humphres Method of Granular Soils. Use the data provided to determine the maximum density based on the gradation of field compaction samples.

301.06 Surface Tolerance. Delete the text of this Subsection and substitute the following:

When grade finishing stakes are required according to Subsection 152.05(f), finish surfaces to within ±0.05 feet from the staked line and grade elevation (or from the design line and grade elevation if Automated Machine Guidance (AMG) methods are used).

When grade finishing stakes are not required according to Subsection 152.05(f), shape surfaces to the required template and check the surface with a 10-foot straightedge. Defective areas are surface deviations exceeding ½ inch in 10 feet between two contacts of the straightedge with the surface.

Correct defective areas by loosening, adding, or removing material; reshaping; and compacting.

301.08 Acceptance. Amend as follows:

Delete the first sentence of the second paragraph and substitute the following:

Aggregate gradation, SEP, and fractured faces will be evaluated under Subsection 106.05.

Delete paragraph (b) and substitute the following:

(b) SE/P200 (SE/P75) Index (SEP). The lower specification limit for the SEP is 1.000.

Add the following:

(c) Fractured faces. The lower specification limit is 50 percent.

Measurement

301.09 Add the following:

Do not measure aggregate base courses placed at the Optional Contractor Staging Areas shown on the plans.

Section 303. — ROAD RECONDITIONING

Construction Requirements

303.06 Aggregate Surface Reconditioning. Amend as follows:

Delete the text of this Subsection and substitute the following:

Excavate 6-inch-deep pothole every 1000 feet along centerline of Mill Creek Road within the Project limits to verify existing aggregate depths. Backfill excavated potholes according to Subsection 204.10. Compact the backfill material according to Subsection 204.11.

Repair soft and unstable areas to the full aggregate surface depth and according to Subsection 204.07. Scarify the thickness of aggregate surfacing material to 6 inches. Remove irregularities and shape to a uniform surface. Finish and compact the surface according to Subsection 302.05.

Add the following:

See ora-umatill582-1_Pavement Evaluation.pdf listed under FAR Clause 52.236-4 Physical Data (Apr 1984), and comply with the recommendations of 6.2.1.
