Friction aggregate shall include only calcined bauxite, corundum, or alternate equal anti‐skid aggregate approved by the Engineer. Aggregate used shall have a minimum hardness value of 8.0 per Mohs Hardness

Scale and be uniformly applied – providing a surface friction value >60 BPN over the entire surface.

6. Friction aggregate size shall be between 0.8‐1.2mm for bicycle facilities and 1.0‐3.0mm for bus facilities and walking facilities.

2025 02890 - 3 6/30/25

A. CST shall be placed as shown on the Plans or as ordered by the Engineer.

B. Before any surface treatment work is begun, a schedule of operations shall be submitted for the approval of the Engineer and his/her authorized representative. At least five (5) days prior to starting application, the Contractor shall provide the Engineer with the color manufacturer's written instructions for use and provide Inspectors access to aggregate for random testing. These instructions shall include, but not be limited to, material mixing ratios and application temperatures.

C. When CST is applied under traffic, the Contractor shall provide all necessary flags, markers, signs, etc. in accordance with the MUTCD to maintain and protect traffic, and to protect marking operations and the markings until thoroughly set.

D. The Contractor shall be responsible for removing, to the satisfaction of the Engineer, all tracking marks and spilled CST applied in unauthorized areas such as utilities, drainage structures, curbs and manhole covers.

3.2 ATMOSPHERIC CONDITIONS

A. CST shall only be applied during conditions of dry weather and on dry pavement surfaces. At the time of installation the pavement surface temperature shall be at or above manufacturer recommendations.

3.3 SURFACE PREPARATION

A. The Contractor shall clean the pavement and existing durable markings to the satisfaction of the

Engineer. At the time of application, all pavement surfaces and existing durable markings shall be free of oil, dirt, dust, grease and similar foreign materials.

3.4 APPLICATION

A. Per manufacturer’s instructions. No CST product shall be spray‐applied without prior written approval from the Engineer.

B. CST shall be placed at the width, thickness, and pattern designated by the Contract Documents.

Surface treatment operations shall not begin until applicable surface preparation work is completed and approved by the Engineer, and the atmospheric conditions and pavement surface temperature are acceptable to the Engineer. The applied film thickness shall be as per manufacturer recommendations

3.5 DEFECTIVE RESULTS

A. The Contractor shall repair the CST if after application and curing it is determined by the Engineer to be defective and not in conformance with this specification. Repair of defective CST shall be the responsibility of the Contractor and shall be performed to the satisfaction of the Engineer as follows:

1. Insufficient film thickness: Repair Method: Clean and prepare the surface of the CST to the satisfaction of the Engineer. Repair shall be made by reapplying CST over the cleaned surface in accordance with the requirements of this specification at the full thickness.

2. Uncured or discolored CST and/or insufficient bond (to pavement surface or existing durable marking): Repair Method: The defective CST shall be completely removed and cleaned to the underlying pavement surface to the satisfaction of the Engineer. After surface preparation work is complete, repair shall be made by reapplying color over the cleaned pavement surface in accordance with the requirements of this specification.

2025 02890 - 4 6/30/25

3. Insufficient coefficient of friction as determined by the Engineer: Repair Method: The defective

CST shall be removed and cleaned to the underlying pavement surface or re‐coated with CST and friction aggregate using a repair method approved by the Engineer. After surface preparation work is complete, repair shall be made by reapplying color over the cleaned pavement surface in accordance with the requirements of this specification.

B. Other defects not noted above, but determined by the Engineer to need repair, shall be repaired or replaced as directed by and to the satisfaction of the Engineer. All work in conjunction with the repair or replacement of defective color shall be performed at the Contractor’s expense.

3.7 WORK ZONE TRAFFIC CONTROL

A. The Contractor is responsible for ensuring appropriate Work Zone Traffic Control (WZTC) in compliance with the MUTCD appropriate for the dry and complete curing time of the selected material applied. The Contractor is responsible to ensure adequate WZTC to prevent those walking, skating, bicycling, and driving from coming into contact with applied material that is still capable of being tracked. The Contractor shall be liable for such tracking and any resulting property damage should it occur.

PART 4 - MEASUREMENT AND PAYMENT

4.1 METHOD OF MEASUREMENT

A. This item will be measured for payment by the total square foot area of CST and shall be the actual number of square feet furnished and installed as directed and approved by the Engineer.

4.2 BASIS OF PAYMENT

A. Work under this item shall be paid for at the contract unit price per square foot of CST which shall be full compensation for all labor, materials, tools, equipment, testing and incidental items necessary to complete the described work to the satisfaction of the Engineer.
