RAISED PAVEMENT MARKERS AND MARKER ADHESIVE
706-1 Description.
Raised pavement markers (RPMs) and adhesive provide a positive guidance system to supplement other reflective pavement markings.
706-2 Materials.
Use only Class B markers, except as follows: For center line rumble strip installations where RPMs are in conflict with the grinding, install Class D RPMs wit h the first application of standard paint. Remove Class D RPMs prior to grinding, then install Class B RPMs in an unground area after grinding. Install Class F RPMs only when shown in the plans. Meet the requirements of Section 970.
706-2.1 Product Ac ceptance on the Project: Use only RPMs and adhesive that are
listed on the Department’s Approved Product List (APL). For Class F RPMs, provide a warranty assigned to the Department in accordance with Section 970.
706-3 Bituminous Adhesive Equipment.
Use equipment having either thermostatically controlled double boiler type units utilizing heat transfer oil or thermostatically controlled electric heating pots to install hot applied bituminous adhesive. Use a melter/applicator unit suited for both melting an d pumping the bituminous adhesive through heated applicator hoses. Heat the bituminous adhesive to between 375°F and 425ºF and apply directly to the bonding surface from the melter/applicator by either pumping or pouring. Maintain the application temperat ure between 375°F and 425ºF. The bituminous adhesive may be reheated. However, do not exceed the manufacturer’s recommendations for pot life at application temperatures.
706-4 Application.
Install RPMs in accordance with the Plans and Standard Plans , Indexes 706-001 and 711-003, prior to opening the road to traffic . Apply RPMs to the bonding surface using bituminous or epoxy adhesives in accordance with the manufacturer’s instructions. Use epoxy adhesives when applying RPMs on concrete pavement. For Class F RPMs, installation may include the removal of roadway surface material to recess a portion of the RPM housing. Prior to application of adhesive, clean the portion of the bonding surface of any material which would adversely affect the adhesive. Apply the adhesive to the bonding surface (not the RPM) so that 100% of the bonding area of the RPM will be covered, in accordance with adhesive manufacturer’s recommendations. Apply sufficient adhesive to ensure that when the marker is pressed downward into th e adhesive, adhesive will be forced out around the entire perimeter of the RPM. Immediately remove excess adhesive from the bonding surface and exposed surfaces of the RPMs. Soft rags moistened with mineral spirits meeting Federal Specifications TT -T-291 or kerosene may be used to remove adhesive from exposed faces of the RPMs. Do not use any other FY 2023-24 Return to Table of Contents solvent. If any adhesive, pavement marking materials or other foreign matter adheres to the traffic face of the RPM, replace the RPM at no cost to the Departmen t. Restore any areas impacted by the installation of Class F RPMs to original condition. Ensure that all final RPMs are in place prior to opening the road to traffic. If more than 2% of the RPMs fail in adhesion or alignment within the first 45 days under traffic, replace all failed RPMs at no expense to the Department. If more than 5% of the RPMs fail in adhesion and or alignment during the initial 45 day period, the Engineer will extend the replacement period an additional 45 days from the date that al l replacement RPMs have been installed. If, at the end of the additional 45 day period, more than 2% of all RPMs (initial installation and 45 day replacements combined) fail in adhesion or alignment, replace all failed RPMs at no expense to the Department.
706-5 Contractor’s Responsibility for Notification.
Notify the Engineer prior to the placement of RPMs. At the time of notification, submit the APL number and the batch or LOT numbers of RPMs and adhesive to be used.
706-6 Method of Measurement.
The quantity of RPMs to be paid for under this Section will be the quantity per each , furnished and installed, completed and accepted.
706-7 Basis of Payment.
706-7.1 Class B RPMs: Price and payment for Class B RPMs will be full compensation
for all work and materials in this Section.
706-7.2 Class D RPMs: Payment will be made in accordance with Section 102.
706-7.3 Class F RPMs: Price and payment for Class F RPMs will be full compensation
for all work and materials in this Section.
706-7.4 Payment Items: Payment will be made under:
Item No. 706 - 1- Raised Pavement Marker - per each. FY 2023-24 Return to Table of Contents SECTION 709 TWO REACTIVE COMPONENTS PAVEMENT MARKINGS
709-1 Description.
Apply two reactive components pavement markings in accordance with the Contract Documents .
709-2 Materials.
Use only materials listed on the Department’s Approved Product List ( APL) as an approved system and meet ing the following requirements : Two Reactive Components ......................... 971-1 and 971 -8 Retroreflective Elements* ................................ ......... 971-1.7 Glass Spheres* ................................ ............ 971-1 and 971 -2 *Use only retro reflective elements or glass spheres recommended by the manufacturer. The Engineer will take random samples of the materials in accordance with the Department’s Sampling, Testing and Reporting Guide schedule.
709-3 Equipment.
Use equipment that will produce continuous uniform dimensions of pavement markings of varying widths and meets the following requirements:
1.Capable of traveling at a uniform, predetermined rate of speed, both uphill and downhill, to produce a uniform application of the two re active components material and capable of following straight lines and making normal curves in true arcs.
2.Capable of applying retroreflective elements or glass spheres to the surface of the completed line by an automatic retroreflective element dispen ser attached to the pavement marking machine such that the retroreflective elements or glass spheres are dispensed closely behind the installed line. Use a retroreflective element or glass sphere dispenser equipped with an automatic cut -off control that is synchronized with the cut -off of the material and applies the retroreflective elements or glass spheres in a manner such that the retroreflective elements or glass spheres appear uniform on the entire pavement markings surface.
3.Capable of providing t he manufacturer’s recommended mixing ratio between the components in a thorough and consistent manner .
709-4 Application.
709-4.1 General: Remove existing pavement markings, such that scars or traces of
removed markings will not conflict with new pavement markings by a method approved by the Engineer. Before applying pavement markings, remove any material by a method approved by the Engineer that would adversely affect the bond of the pavement markings. Offset longitudinal lines at least 2 inches from construction joints of portland cement concrete pavement. Apply pavement markings to dry surfaces only, and when the ambient air and surface temperature is at least 40ºF and rising. Do not apply two reactive components pavement markings when winds are sufficient to cause spray dust. FY 2023-24 Return to Table of Contents
