Do not contaminate the materials. Salvage all material possible from the area which the material is taken. Shape unused portions of a stockpile to Neat Lines. The Contractor will be charged for materials wasted through negligence or used without authority.

00710.11 Emulsified Asphalt Furnish PMCRS-2h polymer-modified Emulsified Asphalt conforming to the requirements of ODOT's publication, "Standard Specifications for Asphalt Materials". Copies of the publication are available from the ODOT State Pavement Engineer. The applicable Specifications are those contained in the current publication on the date the Project is advertised, as modified in this subsection.

Excessive delay in the use of the Emulsified Asphalt or excessive pumping of the Emulsified Asphalt may significantly reduce the viscosity and may make the material unsuitable for chip seal use. For this reason, limit pumping between the bulk storage tank, hauling transportation, field storage tanks and distributor to an absolute minimum to maintain proper viscosity.

Obtain samples of Emulsified Asphalt according to AASHTO T 40 at the frequency indicated in the MFTP. Samples will be tested at the ODOT Materials Laboratory, or other laboratory as designated by the Agency. Polymer-modified Emulsified Asphalt will be tested within 14 Calendar Days from the date it is sampled.

00710.13 Emulsified Asphalt Chip Seal Design Requirements - Do not start placing the Emulsified Asphalt Chip seal on the Project until the Emulsified Asphalt Chip seal design is reviewed by the Engineer and written consent is provided to proceed. The Emulsified Asphalt Chip seal design will be evaluated based on the criteria identified in the latest Oregon Emulsified Asphalt Chip Seal Design Guide available from the Engineer. A new Emulsified Asphalt Chip seal design is required if the Emulsified Asphalt supplier or the source of the Aggregate change during production.

The Emulsified Asphalt Chip seal design shall include the following:

· Gradation and all quality test results, as specified in 00710.10

· Design application rate of aggregate

· Design application rate of emulsified asphalt

When the results from Table 00165-2 yield a Pay Factor of less than 1.00 for any sieve size, the material is non-specification. The Engineer will reject any stockpile of Aggregate containing non-specification material unless the non-specification material is removed from the stockpile. Do not add additional material to such a stockpile until enough non-specification material is removed so that the PF for each sieve size is equal to or greater than 1.00.

(2) Other Tests - Stop production, make appropriate operational adjustments, and remove all failing material from the stockpile whenever a quality control test result, other than sieve analysis, does not meet Specifications. Document operational adjustments made and notify the Engineer prior to resuming production.

(3) Preproduced Aggregate - Compliance of Aggregates produced and stockpiled before the Award of this Contract will be determined by either of the following:

· Continuing production records meeting the requirements of 00710.10 and 00710.15.

If a sublot or partial sublot fails and the remedy is to install an alternate chip seal such as ACP that sublot or partial sublot will not be evaluated or included in the price adjustment. The Engineer may determine that a sublot or partial sublot should be excluded from the evaluation if in the Engineer’s opinion the expected life was reduced in the sublot or partial sublot as a result of winter maintenance activities performed by the Agency.

Prior to the end of the warranty period the Engineer will evaluate each travel lane according to ODOT Provisional Test Method 780. For each sublot the average texture depth will be used to calculate the expected life for the sublot according to Appendix “A” - TM780 Life Expectancy Calculations.

If the calculated expected life (Yf) is greater than or equal to the design life (Yd) then a pay adjustment factor of 1.05 (5% increase) will apply to the pay items in this Section.

If the calculated expected life (Yf) is less than the design life (Yd) then a pay adjustment factor of 0.95 (5% decrease) will apply to the pay items in this Section.

For US20 (Highway 007) the following factors will be used in the calculations:

AADT = 2300

HCV = 20.2%

Nothing in this Subsection limits the ability of the Engineer to take additional action including but not limited to action described in Subsection 00150.25.
