19. PRICE ADJUSTMENT:

19.1 Adjustments will be made to the unit price and extended to the total price paid to the Contractor Tasks 1, 2, 3, 4, 5, 6, 7, 19, 29, 30, 44, 101, 102, 103, 104, 105, 106, 107, 119, 129, 130,144, 201, 202, 203, 204, 205, 206, 207, 219, 229, 230 and 244 if the latest Monthly Fuel Index and/or Asphalt Price Index, as posted on the MODOT website, on the date a Delivery Order is issued, has fluctuated upward or downward by at least __3__ percent from the indexes posted on said website on the date of the bid opening for this contract.

19.1.1. The price adjustment, if any, will be made using the

information posted to the MODOT website located at:

http://modot.org/business/contractor_resources/bidOpenIndex.shtml. Once at the site the Contracting Officer shall select the latest Bid Letting Date that has posted indexes and then select the links “Asphalt Price Index” and “Monthly Fuel Index”. The price adjustments will be calculated as described

01 11 00-8 in Paragraphs 16.2 and 16.3. The price adjustments for fuel and asphalt will then be added to or subtracted from the Unit Price for the Bid Items listed above in this paragraph that are used in the issued Delivery Order for the work being performed. The price adjustments may result in an increase or decrease in the unit price of the Bid Items depending on the change in the indexes.

19.2 Price Adjustment for Fuel: The price adjustment for fuel used in application of asphalt will be based on a Fuel Usage Factor for Production of

2.65 gal/ton of Total Mix and a Fuel Usage Factor for On-Road Hauling of 0.67 gal/ton of Total Mix for a total Fuel Usage Factor of 3.32 gal/ton. This factor will be divided by 9 (nine) to give a factor of 0.37 gal/sq. yd. for a 2” asphalt course. A factor of 0.74 gal/sq. yd. will be used for a 4” asphalt course. The Fuel Usage Factor in gal/sq. yd. will be multiplied by the change in the Monthly Fuel Index as described in Paragraph 16.1. The resulting price adjustment will then be applied to the Unit Price for the appropriate Bid Items.

A = B X (C – D)

Where: A = Adjustment for fuel used in application of asphalt

B = Fuel Usage Factor (0.37 for 2” course of asphalt, 0.74 for 4” course of asphalt)

C = Monthly Fuel Index on the date a delivery order is issued

D = Monthly Fuel Index on the date of bid opening for this contract.

19.3 Price Adjustment for Asphalt: The price adjustment for asphalt will be applied to the actual amount of asphalt binder used by the Contractor for the Bid Items listed in Paragraph 16.1. The change in the Asphalt Price Index, as described in Paragraph 16.1.1, will be divided by 9 (nine) to obtain a price/sq. yd. for a 2” asphalt course. The adjustment factor for a 4” asphalt course shall be calculated by dividing the change in the Asphalt Price Index by 4.5. The percentage of virgin asphalt as shown in the job mix formula submitted by the Contractor, in accordance with Sec 403 of the Missouri Standard Specifications for Highway Construction (1993) will be the basis for adjustments for any asphalt mix type placed. The effective asphalt obtained from the use of recycled asphalt pavement (RAP) will not be eligible for adjustment. To determine the adjustment for asphalt the following formula will be used. The resulting price adjustment will then be applied to the Unit Price for the appropriate Bid Items.

A = B X (C – D) / 9; for a 2” asphalt course

A = B X (C – D) / 4.5; for a 4” asphalt course

Where: A = Adjustment for asphalt

B = % of virgin asphalt binder as listed in the job mix formula in use

01 11 00-9

C = Asphalt Price Index on the date a delivery order is issued

D = Asphalt Price Index on the date of bid opening for this contract.

19.4 Price Adjustment Modifications: Issuance of a delivery order shall constitute notice to proceed. In the event there is an excusable delay of at least 30 days between the date the Delivery Order is issued and the work start date either the Contractor or the Government may request a modification based on significant changes in the Monthly Fuel Index and/or Asphalt Price Index, as posted on the MODOT website, since the Delivery Order was issued.

For the purposes of this paragraph a significant change is a fluctuation upward or downward by at least _3__ percent from the indexes posted on said website on the date the delivery order was issued. The parties will bilaterally negotiate the work commencement date for purposes of calculating any adjustments. No further adjustments will be permitted for changes between the negotiated date and the actual date that work commences. No work will proceed until the modification has been issued by the Contracting Officer.

The price adjustments will be made as described in Paragraphs 16.2 and/or

16.3 except the indexes on the date the Delivery Order was issued will be substituted for the indexes on the date of the bid opening for this contract as illustrated in Paragraphs 16.4.1 and 16.4.2 .

19.4.1 Price Adjustment for Fuel:

A = B X (C – D)

Where: A = Adjustment for fuel used in application of asphalt

B = Fuel Usage Factor (0.37 for 2” course of asphalt, 0.74 for 4” course of asphalt)

C = Monthly Fuel Index on the date of commencement of work

D = Monthly Fuel Index on the date the Delivery Order was issued.

19.4.2 Price Adjustment for Asphalt:

A = B X (C – D) / 9; for a 2” asphalt course

A = B X (C – D) / 4.5; for a 4” asphalt course

Where: A = Adjustment for asphalt

B = % of virgin asphalt binder as listed in the job mix formula in use

C = Asphalt Price Index on the date of commencement of work

D = Asphalt Price Index on the date the Delivery Order was issued.

3.2.2 The sealer shall be mixed in a suitable plant as described in

32 01 13.35-5 paragraph EQUIPMENT. The sealer mixture shall be of the desired consistency with no segregation when deposited on the surface of the pavement. No additional elements shall be added. The sealer mixture shall show no signs of uncoated aggregate, or segregation, or premature breaking of emulsion when applied to the pavement surface.

3.2.3 Where small amounts of sealer are required, making mechanical mixing uneconomical, mixing may be accomplished by hand. The preparation requirements are the same as given in the preceding paragraph for mechanical mixing.

3.2.4 Two coats shall be applied with sand at an application rate of

0.20 gallons per square yard. Each application shall be thoroughly cured before another application is placed. No oversized aggregate particles shall be allowed in the sealer mixture. Streaks shall not be left in the finished surface.

3.2.5 Longitudinal joint between adjacent lanes shall have no visible overlaps, pinholes, or uncovered areas. Thick spots caused by overlapping shall be smoothed immediately with hand squeegees before the sealer mixture cures. Overlaps which occur at transverse joints shall also be smoothed before the sealer mixture cures, so that a uniform surface is obtained which contains no breaks or discontinuities. Joints should be made while the first coat is still workable.

3.2.6 Sealer mixture shall possess sufficient stability so that segregation or premature breaking of emulsion does not occur. The mixture shall be homogeneous following mixing and spreading, free of water or emulsion bleeding.

3.2.7 Areas which cannot be reached with the distributor or areas with minor defects shall have the sealers applied by hand with hand squeegees.

3.3 CURING: Sealed pavement shall be protected from traffic by barricades and markers until the seal has cured a minimum of 24 hours. Areas which are damaged by traffic or from other causes shall be repaired by the Contractor at no additional cost to the Government.

3.4 CLEANUP: On completion of work, all trash, discarded seal material, or other refuse shall be collected and removed from the site and disposed of in accordance with Section 01010: Scope of Work.

3.5 TEST SECTION: Prior to applying the slurry seal, a test section 100 feet long and 20 feet wide shall be placed by the Contractor using the approved mix and equipment in accordance with the specified requirements.

The test section will be evaluated for pavement preparation, workability, stability, curing time, application rate, consistency of thickness, surface finish, joint quality, segregation, premature breaking, and bleeding. The test section may be left in place as part of the finished work if it meets the requirements of the specifications. If not, it shall be removed by the Contractor at no additional cost to the Government.
