About this file
This is a Scope of Work document prepared by the Utah Department of Transportation (UDOT) Region Three for the procurement of liquid asphalt materials. The contract covers the purchase of liquid asphalt products including asphalt binders, emulsions, and cutbacks as defined in UDOT Specification Section 02745. Vendors must be qualified suppliers under the UDOT Materials Qualified Supplier program and comply with the UDOT Quality Management Plan Sections 508 and 509. Orders will be placed on an as-needed basis with no obligation for UDOT R3 to purchase any minimum quantity, with deliveries required within two days of order placement in 35-ton quantities. The contract is for one year with delivery of all products required by May 21, 2026. The scope includes multiple asphalt grades ranging from PG58-34 through PG76-28, as well as various emulsified asphalt products including cationic and anionic types, curing cut-back asphalts, hot-pour crack sealants, and pavement rejuvenating agents. All products must meet specific AASHTO and ASTM test standards with defined compliance and rejection limits for performance-graded asphalt binders and other material specifications.
Vendors must submit required submittals with each shipment and provide all material certifications and test documentation as specified in UDOT Standard Specification 02745. Late charges of $200.00 per hour will be assessed for loads not delivered within the specified timeframe. Vendors are required to maintain compliance with material specifications, and shipments showing contamination with other asphalt grades or materials will be rejected. The document includes detailed technical specifications and test requirements across multiple tables covering various asphalt emulsion types, including High Float Medium Setting grades (HFMS-2, HFMS-2P, HFMS-2SP), High Float Rapid Setting grades (HFRS-2P), Cationic Rapid Setting grades (CRS-2A, B, CRS-2P), Latex Modified Cationic Rapid Setting grades (LMCRS-2), and specialized pavement rejuvenating agent concentrates of Types A through D. Hot-pour crack sealants must meet specific ductility, flexibility, flow, adhesion, and viscosity requirements. Vendors must notify the UDOT Purchasing Agent immediately of any changes to primary contact information.

ATTACHMENT B SCOPE OF WORK
UDOT R3 LIQUID ASPHALT MATERIAL
PUBLICATION
This scope of work is for products to be procured by the State of Utah, Department of Transportation (UDOT), Region Three (UDOT R3), hereinafter referred to as UDOT R3. UDOT R3 does not assume nor accept any liability when this specification is used in the procurement process by any other entity.
PART I: SCOPE OF WORK
1. DESCRIPTION
A. This contract is for the purchase of Liquid Asphalt Materials as described in the Specification.
1. Vendor must supply Liquid Asphalts under the UDOT Materials Qualified Supplier program. Refer to the UDOT Quality Management Plan Section 508 - Asphalt Emulsion and 509 - Asphalt Binder.
2. Refer to Part 2 of UDOT Specification Section 02745 -Asphalt Materials for Liquid Asphalt requirements.
3. Liquid Asphalts are defined as Asphalt Binders, Emulsions, and Cutbacks as identified in Section 02745.
4. If noted, dilution rates for emulsions are based on a ratio of concentrate to water, e.g. a CSS-1 Diluted 2:1 is a dilution consisting of two parts of a CSS-1 concentrate and one part water.
B. Grade of Material
1. The UDOT R3 Agent determines the grade of material to be supplied for each order.
2. SUBMITTALS
A. The vendor must submit all of the required submittals as specified in the 1.5 Submittals section of the UDOT Standard Specification 02745 with each shipment of Liquid Asphalt.
3. ORDERING SCHEDULE AND PICKUP OF MATERIAL
A. UDOT R3 Maintenance personnel will call in an order with a certain quantity to be picked up within 2 days of order placement.
B. Vendor must be able to deliver in 35-ton quantities C. UDOT R3 will charge vendor a late charge of $200.00 per hour for all loads that are late as per the delivery times stated when the orders are placed.
4. NO OBLIGATION TO PURCHASE
A. UDOT R3 will not be obligated to make any order or purchase thereunder should there be no material required for a particular product and/or location. The quantities shown in the Asphalt Bid Estimated Quantities & Zones are estimates only and may not match quantities ultimately ordered.
5. COMPANY CONTACT CHANGES
A. The Purchasing Agent listed at the bottom of the Contract Cover page must be notified immediately if there are any changes to the primary contact listed on the contract cover page, including their e-mail, mailing address, phone or fax number.
6. WAIVER
A. The failure of any party to enforce any of the provisions of this Agreement, or any rights with respect to it, or the failure to exercise any election provided for in it, will in no way be considered a waiver of such provisions, rights or elections, or in any way affect the validity of this Agreement.
