SECTION 1 SCOPE OF WORK AND SPECIFICATIONS
York County is interested in receiving sealed bids from qualified firms who can offer driving surface
aggregate for use by the York County Road Maintenance Department.
It is the intent of these specifications to establish quality standards for driving surface aggregate used
by the York County Road Maintenance Department, to include a method of measurements and a
basis of payment. Only the best commercial practices are to be offered and only materials of first
quality, correct type and size, are to be bid.
York County’s intent is to contract with one qualified firm/company who can provide quality driving
surface aggregate. It is anticipated that an agreement will be offered to the bidder who is determined
to best meet the needs of the County.
SECTION 2 SCOPE AND SPECIFICATIONS
2.1 Scope of Work
All driving surface aggregate complying with the specifications attached shall be picked up at the
vendor’s location and loaded into trucks furnished by York County.
Vendor shall provide a Sieve analysis from on-site sampling and shall submit all applicable AASHTO
tests for review by the County. Aggregate specifications shall be verified by a third-party testing
laboratory not affiliated with the successful vendor. Throughout the duration of this contract, the
County may at its discretion, periodically request up to four (4) additional sets of tests, at the cost of
the vendor, to ensure product consistency.
a. General Description
Driving surface aggregate will be composed of crushed stone, excluding marine limestone, filled and
bound with screenings. The aggregate will be free from vegetable matter, sand, lumps or balls of clay,
or other deleterious matter. Driving surface aggregate will consist of coarse and fine aggregate as
defined in this subsection.
b. Coarse Aggregate
Coarse aggregate will be material retained on the No. 4 sieve consisting of hard, durable aggregate
particles that are reasonably free from thin or elongated pieces, disintegrated particles, vegetable
matter, or other deleterious substances. The maximum abrasion loss for coarse aggregate is 30%
when subjected to the Los Angeles Abrasion Test (AASHTO T 96).
c. Fine Aggregate
Fine aggregate or binder material will be material passing the No. 4 sieve and is subject to the
requirements in this subsection. Fine aggregate for driving surface aggregate will consist of material
produced by crushing operations, free from mineral clay or silt soil, excluding marine limestone.

2.2 Measurement and Payment
The term "ton" shall mean the short ton consisting of 2,000 pounds avoirdupois. All materials, which
are measured and proportioned by weight, shall be weighed on accurate, approved scales by
competent qualified personnel at locations designated by the County. All platform scales shall be of
sufficient size to permit the entire vehicle, or combination of vehicles, to rest on the scale platform
while being weighed. The supplier shall furnish all scales at no cost to the County. The supplier shall
have scales tested by an approved firm, or state agency, as often as the County may deem
necessary to ensure their accuracy. The tare weight of vehicles hauling material being paid for by
weight shall be the empty weight of the vehicle with the driver aboard and the fuel tanks full. All
vehicles shall be weighed once each week to determine their tare weights and except as provided
below, this tare weight shall be used for the calendar week in computing net weights. During the
course of the calendar week, vehicles may be spot checked for tare weight. If the spot check shows
the tare weight of any vehicle is exceeded by 100 pounds during regular weekly weighing, then the
tare weight determined during spot checking shall be used to compute the net weights until the next
weekly tare weights are determined. If the tare weight of the vehicle is less than the tare weight found
at the weekly weighing, the tare weight determined at the weekly weighing shall be used in computing
net weights for the calendar week. For proper identification each vehicle shall display a legible
identification number and county emblem.
a. Method of Measurement
Driving surface aggregate will be measured in tons and the quantity shall be the number of tons of
base material, including normal moisture found in stockpiled materials, weighed on approved scales.
b. Weight Tickets
The net weight of each load of material and the accumulated weight of the loads for the day shall be
recorded in duplicate, on forms suitable to the County. When each load of materials is delivered, one
copy of the weight ticket shall be presented to the representative of the County. At any time during
the delivery of materials and for the purpose of checking the weighing equipment, the County may
direct the supplier to weigh on tested and/or approved platform scales, without additional
compensation, any truckload that is to be delivered to the work site.
c. Basis of Payment
The driving surface aggregate will be paid for at the contract unit price per ton and said price and
payment shall be full compensation for furnishing all materials. Payment will be made on all invoices
received by the last day of each month. Payment will be made within fifteen (15) days after receipt of
said invoice. Invoices are to be sent to the Road Maintenance Department, PO Box 120, York, South
Periodically, other county departments make special request for stone. When this situation occurs a
separate Purchase Order number will be issued to the successful vendor and the contracted price per
ton in this bid will be used.
