757-A Portable Traffic Signal, Type _*_ - per Each 757-B State Retained Portable Traffic Signal, Type _*_ - per Each 757-C State Furnished Portable Traffic Signal, Type _*_ - per Each * Specify Type (TR1 or TR2) MATERIALS 665

800.01General

All materials used in the work shall be new, unused material that will meet the requirements described in this Division, unless the same are altered by specific requirements of any Section of these Specifications, Special Provisions, or by modifying notes on the plans. All materials shall also meet the requirements of applicable portions of Section 106 which will supplement the requirements of this Section. All tests shall be in accordance with the current Departmental testing schedule.

800.02Inspection Arrangements

It shall be the duty of the Contractor to notify the Engineer of the source of the various materials required for each project. This notice shall be received sufficiently in advance of any shipment of materials so that inspection may be arranged at the producing plant if the Engineer so elects.

Whenever the quantity of materials warrants such an arrangement and/or it is economically advantageous to the Department, the inspection of materials at the original or immediate source of supply will be made. However, the Department is under no obligation to the Contractor to inspect materials until it arrives at the site of the work. In general, all aggregates, soil, brick, reinforcing and structural steel, bituminous materials, timber, lumber, piling, and posts which are to become a part of the completed work will be inspected at the point of production. For timber, lumber, piling, and posts which are to be given preservation treatment, this inspection will be performed at the treating plant in conjunction with inspection of the treating process.

 For lumber and timber products, the producer shall have sorted his stock and shall have separated a sufficient quantity of material to ensure that all of each item for inspection is available before the Inspector is called. In the event that part of the shipment is rejected because of failure to meet the specification requirements, the producer shall furnish other stock to replace the rejected items.  Should the quantity of any material rejected for failure to meet specification requirements amount to 20 percent or more of the material inspected and tested at that time, the inspection operation will be suspended until the producer shall have regraded his stock or revised his production methods to produce material uniformly conforming with the specifications.  When sampling stockpiles of aggregates, base materials, etc., the average of all samples must be within the gradation band required for the size aggregate specified. In no case will stockpiles be acceptable if more than 20% of the total samples fall outside the gradation band. In addition, any failing sample must be within 20% of the range specified for any designated sieve.  In case the stock has not been properly prepared or separated before calling an Inspector, or in case of delay in replacement of rejected material, the extra inspection cost occasioned by such delay will be charged against the Contractor for whom the material is being produced and will be deducted from any sums due or which may become due the Contractor.  Where a Contractor's producer or jobber requests inspection of material for warehouse stock or for use in plants where stocks of materials inspected and accepted for use in highway construction or maintenance cannot be kept separated from materials which are to be used on other work, the cost of inspection of those materials which have been approved for highway work, but are later diverted to other uses not connected with the Department's MATERIALS 666

highway construction or maintenance, will be charged to the Contractor who requested such inspections.

800.03Testing, General

Where maximum and minimum specification limits are given, it is intended and expected that materials having approximately mean values will be furnished under the respective specifications. The established allowances for variations in the determination of these values are considered in establishing the limits and no tolerances in excess of the established variation allowances will be permitted unless so specifically stated in the proposal or on the plans. Unless otherwise specified in the test procedure or material specification, all test results will be rounded off in accordance with ASTM E 29 and reported to the same number of places as the specification. Where material is fabricated of or treated with another material or any combination of materials is assembled to form a product, any or all of which are covered by these specifications, the failure of any of the components of the product to comply with the designated specifications shall be deemed sufficient cause for the rejection of the whole. The sieves used for testing materials shall be woven wire cloth conforming to ASTM E 11.

800.04Tests for Concrete Materials

Preliminary samples of fine aggregate, water, and cement shall be subject to both 7 and 28 day tests or their equivalent and acceptance based thereon. During the progress of the work, these materials may be accepted on the basis of the 7 day test, except that Type III cement may be accepted on the basis of the 3-day test.

800.05Bituminous Mixture Stability and Density Test

These tests shall conform to the current methods as described in ALDOT-307 or ALDOT-344, depending on the maximum aggregate size.

800.06Measurement of Liquid Bituminous Materials

Actual measurement shall be in accordance with the provisions of Subarticle 109.02(a) and/or (b).

Unless otherwise provided in the proposal form, the procedure in conjunction with all shipments in tank cars or trucks shall be as follows:

(Form BMT-146) for each shipment, containing the following information:
