Weight Items

Area items include items with the following Units of Measure:

  • POUND (LB)
  • TON

Refer to the Measurement and Payment Guidelines topic for details on significant figures and requirements for measurement and payment.

Mobile Inspector documentation examples for a few weight items are illustrated in this topic. Some minor modifications may be required to show the unusual circumstances which may occur with different items, but the general format should be followed. If there are items which cannot be documented according to the following examples, contact the Construction Admin Services Section for assistance.

This topic includes separate sections for details on:


Weight Item Notes

  • Turn in paper calculation sheets to the Office Manager.
  • A photo of a label on any container must be taken and emailed to the crew office to document the quantity. This photo is saved to the appropriate Contract Files\Contract\07 Estimates directory.
  • Payment for POUND (LB) for Reinforcing Steel is based on the Contract plan's Bill of Materials. If plan quantity is different, field measurements and calculations (per Standard Specifications, Subsection 505.04.01 Measurement, are required.
  • If using information from the Standard Plans, then include the table reference callout.

    • Weight Item Calculation Formulas

    While not common, Inspectors may show the calculations for ton items when weights (computerized load tickets) cannot be obtained. The calculations are found in the Calculation Formulas topic.

Liquid and Emulsified Asphalt Items

Theoretical application rates are NOT permitted to be used to determine the total tons placed for payment of all Liquid and Emulsified Asphalt items.

Liquid Asphalts

Liquid Asphalts are typically used for prime coats and curing seals. These items are typically paid for by the square yard.

  • Liquid asphalts are also referred to as cut-back asphalts and include MC-70, MC-250, etc.
  • Liquid asphalts will be documented in the Record of Delivery—Liquid Asphalt and the Liquid/Emulsified Asphalt Application and Payment spreadsheets.
  • When another material has been approved for use in lieu of the liquid asphalt, there may be different application rates and dilution factors that must be documented. Make sure to check the contract’s Special Provisions and/or the manufacturer’s recommendation to ensure proper application.
  • Use the Agreement Estimate report as a reference to ensure that items and quantities are paid in the correct category (AEB).
  • Information on Liquid Items are found on the Summary of Quantities sheets in the Contract plans.
  • There are 3 ways to document the application of Liquid Asphalt:
    • Total delivery (Bill of Lading)
    • Weigh Back - Weighing the trucks over the Contractor’s scales
    • Gallon Meter - List the following in the Remarks box of the posting tab in the Inspector’s DWR.
      • Beginning meter reading
      • Ending meter reading
      • Gallons used

        • Note: NDOT does not apply a Temperature Volume Correction factor.

  • In no case will the Liquid Asphalt pay quantity exceed the total certified asphalt delivered less any material wasted or left in storage.

Emulsified Asphalts

Emulsified Asphalts are typically used for tack coats, seal coats, chips seals and cold in place recycle. These items can be paid for by square yard, tons or they may be incidental to other items of work.

  • Emulsified asphalts (CMS-2S, SS-1h, LMCRS-2H, etc.) will be documented in the Record of Delivery—Liquid Asphalt and the Liquid/Emulsified Asphalt Application and Payment spreadsheets.
  • It is the Inspector’s responsibility to ensure proper dilution and application rates regardless of the item’s UOM.
  • Emulsified asphalt is delivered either diluted or undiluted.
    • If the emulsified asphalt is delivered diluted, verify the proper dilution ratios are on the Bill of Lading.
    • If the emulsified asphalt is delivered undiluted, use the Oil and Water Check Sheet to verify the correct gallons of water were added.

      • Note: The Liquid/Emulsified Asphalt Oil and Water Check Sheet is designed to assist the inspector in determining the correct pounds/tons of water added to the oil to get the approved oil/water ratio. Refer to the Liquid/Emulsified Asphalt Oil and Water Check Sheet in the Fourth tab of the Liquid/Emulsified Asphalt Application and Payment spreadsheet.

  • Once proper dilution is obtained for the specified application, measurement for payment and application rate can proceed.
  • There are 3 ways to document the application of Emulsified Asphalt:
    • Total delivery (Bill of Lading)
    • Weigh Back - Weighing the trucks over the Contractor’s scales
    • Gallon Meter - List the following in the Remarks box of the posting tab in the Inspector’s DWR.
      • Beginning meter reading
      • Ending meter reading
      • Gallons used

        • Note: NDOT is no longer applying a Temperature Volume Correction factor.

  • In no case will the emulsified asphalt pay quantity exceed the total certified asphalt delivered less any material wasted or left in storage.

Liquid/Emulsified Asphalt Items

  • Collect a Bill of Lading (B/L) for each delivery of liquid/emulsified asphalt.
    • Record the Contract ID in the upper right-hand corner.
    • Check and initial all weight calculations.
    • Turn into the Office Manager each day.

      • Note: Each B/L for emulsified asphalts must show the weight of raw asphalt separately from the water added or show the mix percent. If the emulsified asphalt is delivered without this information on the B/L, the Resident Engineer shall inform the Contractor that it is unacceptable, and any application shall be done without payment. The B/L must plainly state whether the material was delivered diluted or undiluted. The Inspector is responsible for documenting (on the B/L) the weight of raw asphalt separately from the water added.

  • Collect a Material Certification for each delivery of Liquid and Emulsified asphalt.
    • Record the Contract ID in the upper right-hand corner if you receive a paper copy.
    • Turn into the Office Manager each day.
  • It is the Inspector’s responsibility to ensure proper dilution and application rates regardless of the item’s UOM or payment.
Record of Delivery—Liquid/Emulsified Asphalt Spreadsheets

The Record of Delivery – Liquid Asphalt and Emulsified Asphalt (Diluted/Undiluted) spreadsheets are used to track the asphalt delivered to the job site. Separate spreadsheets will be provided for liquid asphalts and emulsified asphalts (dilute)/(undiluted). The spreadsheets are used as part of the source documents for payment.

  1. Open the Liquid/ Emulsified Asphalt Application and Payment spreadsheet from the appropriate crew SharePoint Contract Files > Contract > 08 Scale Weights directory.
  2. Select the appropriate Record of Delivery tab at the bottom of the spreadsheet and record the following:
    • Inspector’s initials
    • Date delivered (May not be the same date the load was applied.)
    • Truck No.
    • Trailer No. If applicable
    • Bill of Lading No.
    • Tons delivered
    • Remarks
  3. SharePoint will automatically save the file as data is entered into the spreadsheet. Review entries and close the spreadsheet.


    4. Note: The following example shows the 4070190 - Emulsified Asphalt, Type SS-1H (Diluted) item used for Seal Coat.


Liquid/Emulsified Asphalt Application and Payment Spreadsheet

The Liquid/Emulsified Asphalt Application and Payment spreadsheet is used to track asphalt applications, payments and oil/water ratios. Each liquid/emulsified asphalt bid item will be documented on a separate spreadsheet. The spreadsheet is used as part of the source documents for payment.

  1. Open the Liquid/Emulsified Asphalt Application and Payment spreadsheet from the appropriate crew SharePoint Contract Files > Contract > 08 Scale Weights directory.
  2. Select the appropriate tab at the bottom of the spreadsheet: Prime Coat, tack Coat, or Seal Coat.
  3. Record the following:
    • Contract Number
    • Item Description
    • Item Number
    • Dilution % Factor: Enter as whole number (60/40 mix enter as 60)
    • Bill of Lading Tons Delivered per day: If item is delivered diluted, enter tonnage per day and place 100 in Dilution % Factor
    • Insp: Inspector initials
    • Date
    • Station to Station: Complete station to station, including line designation and LT, RT, or CL.
    • Length: Actual length measured in feet, NOT ‘Station to Station’.
    • Width: Actual Width measured in feet, NOT ‘Varies Width’.
    • For Total SQYD, Gallons, and App Rate:
      • Enter Length, Width and Gallons (Using the digital meter from the truck; take the beginning read minus the ending read for the gallons placed). If using the Bill of Lading tons or the Weighback tons, the calculation is provided on the Liquid/Emulsified Asphalt and Payment spreadsheet to determine.
      • Once the gallons are determined and entered, the computer will calculate the Tons and the App. Rate column. When entering the gallons per stationing, the App. Rate is calculated for that station only. When there are multiple stations but are only documenting the total gallons placed for the day on the last line, the spreadsheet will calculate the App. Rate for that last station only; however, it will total the the SQYDs, Gallons, Tons and App. Rate for the entire day at the bottom of the page.
      • If at any time the "Total Tons Remaining (Diluted)" number is red, there were not enough Bill of Ladings (B/L) collected to cover the material placed. If this is the case, obtain additional B/Ls.
      • Remarks: Add the Category/AEB of where the material is to be paid. If paid in more than one Category/AEB, break out how much are paid in each. If the item is incidental, document how much was incidental. If paid by the SQYD, add the total SQYD per day to show how much SQYD will be paid on the estimate.
  4. SharePoint will automatically save the file as data is entered into the spreadsheet. Review entries and close the spreadsheet.

    5. Note: Pay will be based on delivery minus waste and/or material left in storage, not based on the application rate. In no case will the liquid asphalt pay quantity exceed the certified total asphalt delivered, less any wasted material and less any material left in storage.




    Note: The following examples show the 4070190 - Emulsified Asphalt, Type SS-1H (Diluted) item used as both a Tack Coat and a Seal Coat.




    NOTES for Emulsified Asphalt item postings only:

    • If the total tonnage placed was based off reading the gallon meter, the Inspector must document the beginning and ending meter reading and the gallons used in the Remarks box of the posting tab in the DWR.
    • If the truck sprays completely out, the total tons delivered listed on the Bill of Lading (B/L) must be converted to gallons by applying the formula listed in the top right corner of the spreadsheet. The total gallons must then be documented in the "Gallons" field and the computer will automatically fill in the Tons field.
    • If a weighback is needed and provided, then the total tons placed according to the weighback must be converted into gallons and documented in the "Gallons" field.
    • If the entire truck was not sprayed out and the Contractor does not provide a weighback ticket, or a working gallon meter reading, Liquidated Damages will be assessed per the Special Provisions, Subsection 109.02, (Measurement and Payment) Scope of Payment.
    • It is the Inspector’s responsibility to verify that the application rate falls within an acceptable range according to the Standard Specifications.
Oil and Water Check Sheet

When the emulsified asphalt is delivered raw and placed in a tank, obtain a tare weight on the distributor truck before the asphalt and water is added. When the asphalt is added, the truck will be weighed and then weighed again when the water is added. The ratio of oil to water will vary depending on the specification and the type of material. Make sure to check the Special Provisions to ensure the correct ratio is being used. When the truck is finished spraying for the day, the truck will be weighed once again to determine what was placed for the day, as shown below. Use the Oil and Water Check Sheet to verify the dilution rates are correct.

Note: Make sure that any water ratio calculations are documented on the Bill of Lading sheets.

Note: Check the Manufacturer’s Recommendation for the specific material and the Special Provisions for the contract to assure the correct oil/water ratio is being applied.

  1. Open the Liquid/Emulsified Asphalt Application and Payment spreadsheet from the appropriate crew SharePoint Contract Files > Contract > 08 Scale Weights directory and go to the Oil & Water Check Sheet tab.
