- 166 - SECTION 306 -- GRANULAR FILL
306.01 Description
1.The Contractor shall complete the following requirements under the "Granular Fill" bid item:
a.Furnish and place a layer of compacted granular material. The granular fill shall be constructed in accordance with these Specifications and in conformity with the lines, gr ades, quantity requirements, and cross sections shown in the contract.
306.02 Material Requirements
1.The granular material shall meet the requirements in Subsection 1033, and Table 1033.02, Clas s B, unless specified otherwise in the contract.
306.03 Construction Methods
1.The Contractor shall haul the granular fill material to the road, spread it in uniform layers, and com pact it to not less than 100% of maximum density as determined by NDOT T 99.
2.Any portion of the granular fill which is to be used as aggregate in a bituminous sand base course mixture need not be compacted.
3.This work shall be performed in accordance with the requirements in Subsection 205.03.
306.04 Method of Measurement
1.The Contractor shall number, l abel, and tally the delivery tickets and then prepare a report of the quantitie s and distribution of the materials. A copy of the report shall be given to the Engineer at the end of each day when hauling materials.
2.Granular material shall be measured in cubic yards (cubic meters) at the point of delivery. T he Contractor shall level the material even with the top of the truck's hauling box to allow accurate volume measurement.
3.Instead of leveling the material in the hauling vehicles, the Contractor may heap the loads to an agreed volume.
4.Water applied at the Engineer's direction will be measured in accordance with Subsection 302.04.
306.05 Basis of Payment
1.Pay Item Pay Unit Granular Fill Cubic Yard (CY) [Cubic Meter (m3)] Water 1,000 Gallons (MGAL) [kiloliter (kL)] 2. Payment is full compensation for all work described in this Section. - 167 - SECTION 307 -- FOUNDATION COURSE
307.01 Description
1.The foundation course is a laye r of compacted material conforming to the lines, grades, and dimensions shown in the contract. The foundation course shall be built on a finished subgr ade. The Contractor shall complete the following requirements under the foundation course bid items including but not limited to:
a.Adjust grade lines to meet intersections, pavements, bridge ends, railroad crossings, or any other physical features designated by the Engineer.
b.Process the source material.
c.Placement of the foundation course.
d.Compaction of the foundation course.
e.Profiling the foundation course. f. Disposal of excess material after profiling is completed. 2. The types of foundation course are: a. Bituminous.
b.Crushed concrete.
c.Aggregate Foundation Course - D.
307.02 Material Requirements
1.a. All samples, including fiel d samples, will be washed sieve. All samples will be taken from the project grade prior to the spreading operations.
b.The Contractor shall handle all material in such a manner that prevents contamination.
2.Bituminous Foundation Course: a. Material used in constructing bituminous foundation course shall consist of salvaged bituminous material. The source of the salvaged bituminous material will be described in the contract.
b.All salvaged bituminous material must be less than 3 inches (75 mm) in maximum dimension and shall not contain more than 5% by weight of material retained on a 2 inch (50 mm) sieve just prior to its use.
1.Contractor Production (i) All salvaged bituminous material produced by the Contractor from pavement removal or by cold milling material from the existing pavement structure on the proj ect, whether hauled directly to the site of use or temporarily stockp iled, shall be screened to meet the requirements of Paragraph 2.b. (ii) If, after screening, ther e is insufficient material to produce the plan quantity, the Engineer may order the oversized salvaged bituminous material to be further proces sed at no cost to the State prior to delivery to the roadway. Processing shall mean crushing, pulverizing, re-screening, or a combination of these methods.
