Article 1107.02, Insurance, is amended by the following modifications and additions.
This proposal note becomes null and void January 1, 2027.
A. It shall be the Contractor's responsibility to have liability insurance covering all
of the construction operations incident to contract completion and the Contractor must
have on file with the Contracting Authority a current "Certificate of Insurance" prior to
award of contract. The certificate shall identify the insurance company firm name and
address, Contractor firm name, policy period, type of policy, limits of coverage, and

insured party, or a separate owner's protective policy shall be filed showing the
Contracting Authority as an insured party.
C. The liability insurance shall be written by an insurance company (or
companies) qualified to do business in Iowa. For independent contractors engaged
solely in the transportation of materials, the minimum coverage provided by such
insurance shall be not less than that required by Chapter 325A, Code of Iowa, for such

DEVELOPMENTAL SPECIFICATIONS
FOR
DIAMOND GRINDING RUMBLE STRIPS
Effective Date
October 20, 2026
THE STANDARD SPECIFICATIONS, SERIES 2023, ARE AMENDED BY THE FOLLOWING
MODIFICATIONS AND ADDITIONS. THESE ARE DEVELOPMENTAL SPECIFICATIONS AND THEY
PREVAIL OVER THOSE PUBLISHED IN THE STANDARD SPECIFICATIONS.
23088.01 DESCRIPTION.
Provide equipment, furnish all necessary labor and materials, and perform all operations necessary for
diamond grinding standard or sinusoidal rumble strips in HMA or PCC surfaces. Diamond grind rumble
strips to the dimensions and spacing shown in the contract documents. Apply diluted asphalt emulsion to
the diamond ground shoulder rumble strips on HMA surfaces by means of a bituminous distributor.
23088.02 MATERIALS.
A. Use asphalt emulsion Grade CSS-1, CSS-1h, SS-1, or SS-1h meeting requirements of Section
4140 of the Standard Specifications.
B. Dilute the asphalt emulsion with water prior to application to the milled shoulder rumble strip. The
dilution rate is one part of asphalt emulsion to one part of water.
23088.03 CONSTRUCTION.
A. General.
1. Notify the Engineer if degraded areas are encountered that will not accommodate diamond
ground rumble strips. Skip those sections.
2. Allow PCC to cure for a minimum of 14 days prior to placing diamond ground rumble strips.
When maturity is used for opening, placement of diamond ground rumble strips may begin
when 350psi flexural strength is achieved.
B. Equipment.
1. Perform grinding using stacked diamond blades mounted on a self propelled machine that
has been designed for grinding PCC or HMA surfaces. Polycrystalline diamond (PCD) heads
are not considered an approved equal for stacked diamond blades. Ensure the equipment will
not cause strain or damage to the underlying pavement.
2. Do not use grinding equipment that causes excessive ravels, aggregate fractures, spalls, or
excessive disturbance of the transverse and/or longitudinal joints. The finished surface after
grinding the rumble strips should have a corduroy like texture.
3. For standard rumble strips use grinding equipment with a minimum effective head width
suitable for grinding the entire width of the rumble strip in one pass. For centerline rumble
strips use a grinding head equipped to grind the rumble strip on each side of the centerline in
one pass.
4. Select the blade type and number of blades per foot to provide proper surface texture based
on the material being ground, in particular, the coarse aggregate type.
C. Test Strip.
Demonstrate to the Engineer on an initial 500 foot test section that the equipment and method will
provide the desired diamond ground rumble strip and surface inside each depression without
damaging the adjacent pavement. If the desired results are not being provided, as determined by
the Engineer, provide different equipment or methods, or make necessary adjustments to provide
the desired results. If the initial 500 foot section results are unsatisfactory, repair or replace the
section as determined by the Engineer, at no additional cost to the Contracting Authority.
D. Grinding.
1. Grind shoulder rumble strips in a straight line, offset from the painted edge line as shown in
the contract documents. Do not deviate from that offset more than ±2 inches. Ensure the
depth of the rumble strips is as shown in the contract documents. The Engineer will randomly
check the alignment and depth.
2. Grind centerline rumble strips in a straight line, on the centerline joint as shown in the
contract documents. Do not deviate from that location more than ±1 inch. Ensure the depth of
the rumble strips is as shown in the contract documents. The Engineer will randomly check
the alignment and depth.
3. Continuously remove all slurry or residue resulting from the grinding operations. Do not
deposit on the slab or shoulder. Leave pavement and paved shoulders in a clean condition.
Ensure residue from grinding operations does not flow across lanes occupied by public traffic.
This residue may be spread on the foreslope or removed according to Article 1104.08 of the
Standard Specifications. When residue is deposited on the foreslope in areas where cable
guardrail is present, spread the residue in a manner that prevents it from collecting in the
sockets for the cable guardrail system. Take measures to prevent damage to vegetation
during spreading of residue. If damage occurs, repair at no cost to the Contracting
Authority. Do not allow discharge of slurry or residue into gutters, drainage facilities, or
bodies of water.
E. Asphalt Emulsion Fog Seal.
Per Article 2548.03, C of the Standard Specifications.
F. Limitations.
Do not disturb desirable grass areas and desirable trees outside the construction limits. Do not
park or service vehicles and equipment or use these areas for storage of materials. Obtain the
Engineer’s approval for storage, parking, and service areas.
23088.04 METHOD OF MEASUREMENT.
Measurement will be as follows:
A. Diamond Ground Shoulder Rumble Strips.
Stations shown in the contract documents for each type, measured along each edge of mainline
pavement. Unless stated otherwise in the contract documents, no deduction will be made for
gapped areas. The quantity will be adjusted for the length of degraded shoulders skipped, asDS-23088, Page 3 of 10
defined in Article DS-23088.03 of this specification. The quantity will be adjusted for test sections
that were deemed unsatisfactory.
B. Diamond Ground Centerline Rumble Strips.
Stations shown in the contract documents for each type, measured along the centerline of
mainline pavement. Unless stated otherwise in the contract documents, no deduction will be
made for gapped areas. The quantity will be adjusted for the length of degraded pavement
skipped, as defined in Article DS-23088.03 of this specification. The quantity will be adjusted for
test sections that were deemed unsatisfactory.
C. Asphalt Emulsion for Fog Seal (Shoulder Rumble Strips).
Gallons computed from field measurements of distributors or from tank cars or transport trucks as
provided in Article 4100.03 of the Standard Specifications. When quantities computed from field
measurements check within 1.0% of the billed gallons, payment will be based on billed gallons.
When quantities computed from field measurements differ from billed gallons by more than 1.0%,
payment will be based on the quantity from field measurements. From these quantities, any
amount used by the Contractor as fuel, left in cars, or otherwise not delivered to the road surface
will be deducted. The Engineer will advise the Contractor promptly, in writing, of quantities
deducted.
23088.05 BASIS OF PAYMENT.
Payment will be the contract unit price as follows:
A. Diamond Ground Shoulder Rumble Strips.
Per station for the type specified.
B. Diamond Ground Centerline Rumble Strips.
Per station for the type specified.
C. Asphalt Emulsion for Fog Seal (Shoulder Rumble Strips).
1. Per gallon for undiluted Asphalt Emulsion for Fog Seal (Shoulder Rumble Strips) that is
mixed and used on the project. Diluted asphalt emulsion that is delivered to the project site,
but not applied to the roadway surface will not be considered for payment.
2. Payment is full compensation for cleaning the shoulder surface, furnishing and applying
diluted asphalt emulsion, mixing water, and protecting the adjacent pavement and edge lines.DS-23088, Page 3 of 10
