REQUEST FOR PROPOSAL

COLD MIX ASPHALT

(December 15, 2025)

Ellis County Public Works is requesting proposals to produce cold mix asphalt materials for the 2026 asphalt program.

A minimum of 8,000 tons and a maximum of 12,000 tons, with the tonnage amount to be determined later is required

for bidding purposes. Base bid shall be for contractor to supply aggregates (½” chips, ¼” screenings and sand) and

mixing for the cold mix with Ellis County separately contracting asphalt oil (emulsion). Contractor will be required to

mix asphalt utilizing Ellis County’s and KDOT’s Standards and Specifications as stated in paragraph two (2) of this

Request for Proposal. The contractor will furnish all labor, equipment, and fuel necessary to mix and deliver products

to the Ellis Yard located at 500 East 9th Street, Ellis, Kansas. An alternative option may be considered to permit Ellis

County Public Works to transport the finished product. Contractor may propose alternate sites for consideration by

Ellis County during the selection process. Also, contractor shall produce and stockpile products for Ellis County to

haul from location as needed during the 2026 Asphalt Season. Stockpiles of produced asphalt must be kept and

maintained in cone shape piles to promote water run-off and reduce water absorption. If this is not possible, or

stockpile area is restricted, asphalt must be produced on an as needed basis determined by Ellis County. If asphalt

is produced on an as needed basis, liquidated damages amounts will be adjusted by Ellis County as needed. The

work shall consist of providing aggregate materials, running, and drying materials through your drum mixer asphalt

plant and adding County furnished asphalt oil. Ellis County will provide asphalt from our asphalt supplier at the

percentage we desire.

All asphalt mixing shall conform to the Requirements of Division 600 of the Standards and Specifications for State

Road and Bridge Construction and Kansas Department of Transportation, with special attention given to

temperatures. The maximum temperature of the finished product from the discharge chute shall be no more than

185 to 200 degrees Fahrenheit for the use of CMS-1 emulsion asphalt. The workability of the finished product must

be maintained, and stockpile workability and longevity must be maintained. All produced asphalt will ultimately be

bladed on Ellis County roads by county forces. Weight of the total mix shall be based on the mixing plant aggregate

totalizer, or a calculated weight obtained from scales provided by the contractor. Fiscal Year 2026 mix components

are 15% ½” chips, 65% ½” sand, and 20% ¼” screenings, with an estimated 5.8-6.25% emulsion. A second mix

component may be considered with 60% sand, and 40% screenings with an estimated 6.8% to 7.0% emulsion. Final

gradations and mixed quantities will be provided prior to notice to proceed. (Only CMS-1 emulsion asphalt shall be

considered for the asphalt mix design). Mix design is subject to change due to aggregate availability.

Ellis County requires that all products be available and transported or stockpiled at pre-approved site no later than

May 28, 2026. Liquidated damages in the amount of $500.00 for each calendar day, exclusive of Sundays and legal

holidays, shall be charged for each day that the work remains uncompleted. When requested, the respective

contractor shall perform extraction tests on site to ensure the finished product will meet the specific mix design as

furnished by the County Public Works Director. All test results shall be documented and provided to the Ellis County

Public Works Director, 1681 250th Avenue, Hays, KS 67601. A preproduction dry sample shall be required prior to

commencement of mixing asphalt and submitted to our office 24 hours prior to production.

All materials shall be guaranteed as specified in scope of work and shall be completed as date specified in Request

for Bid Proposal. Upon unforeseen circumstances, a written notification shall be required and submitted to the Ellis

County Public Works Director for approval of extension. If approval is granted, the extension shall not exceed 10 days.
