Section 634

Section 634 – PERMANENT PAVEMENT MARKINGS

Description

634.01 This work consists of applying markings and markers on finished pavement.

Pavement markings are designated as follows:

Type A – Solventborne pavement markings Type B – Waterborne pavement markings Type C – High-build waterborne pavement markings Type D – Epoxy pavement markings Type H – Thermoplastic pavement markings Type J – Preformed pavement marking tape Type L – Methyl metharcrylate pavement markings

Material

634.02 Conform to the MUTCD and the following Subsections:

Solventborne Pavement Markings 718.08 Waterborne Pavement Markings 718.09 High-Build Waterborne Pavement Markings 718.10 Epoxy Pavement Markings 718.11 Thermoplastic Pavement Markings 718.12 Preformed Pavement Markings 718.13 Glass Beads 718.14 Pavement Markers 718.15 Temporary Pavement Markings 718.16 Epoxy Resin Adhesives 718.17 Methyl Methacrylate Pavement Markings 718.18

Construction Requirements

634.03 General. Where existing and final marking locations are identical, stake the limits of existing markings before starting pavement work.

Submit manufacturer’s SDS and product data sheets at least 7 days before applying markings. A field demonstration may be required to verify the adequacy of the material.

Ship marking material containers plainly marked with the following information as appropriate for the material being provided:

(a) Manufacturer’s name and address;

(b) Name of product;

(c) Lot and batch numbers;

(d) Color;

(e) Net mass and volume of contents;

(f) Date of manufacture;

(g) Date of expiration;

(h) Statement of contents;

(i) Mixing proportions (if mixing of components is required); and

(j) Safety information.

Establish marking patterns and locations according to the MUTCD and as shown in the plans.

In curve widening areas, establish the edge line markings at the limits of the traveled way and the centerline markings equal distance between the edge lines.

Remove loose particles, dirt, tar, grease, and other deleterious material from the surface to be marked. Where markings are placed on rigid pavement less that 1-year old, clean the pavement of laitance and curing compounds.

Remove temporary markings the same day permanent markings are applied. Remove temporary and conflicting makings according to Subsection 635.14 before applying permanent markings.

Wait at least 14 days before applying markings on new asphalt pavements or new asphalt surface treatments.

Apply markings to a clean, dry surface and according to the manufacturer’s recommendations. Produce markings that are clean-cut and uniform in appearance by day and night.

Current state-approved marking material may be used if approved.

Apply glass beads at the rate, type, and timing according to the manufacturer’s recommendations and immediately following marking application to ensure adhesion.

Protect markings from traffic until dried to a no-tracking condition. Remove tracking marks, spilled marking material, markings in unauthorized areas, and defective markings.

634.04 Solventborne Pavement Markings (Type A). Apply markings when pavement and air temperatures are at 35 °F and rising. Do not heat the markings above 120 °F. Spray markings at a 15-mil minimum wet film thickness or at a rate of 107 square feet per gallon.

On new asphalt pavements or new asphalt surface treatments, apply two coats of markings and glass beads. Apply second coat after first coat is track free.

634.05 Waterborne Pavement Markings (Type B). Apply markings when pavement and air temperatures are 50 °F and rising.

Do not heat the markings above 120 °F. Spray markings at a 15-mil minimum wet film thickness or at a rate of 107 square feet per gallon.

On new asphalt pavements or new asphalt surface treatments, apply two coats.

634.06 High-Build Waterborne Pavement Markings (Type C). Apply markings when pavement and air temperatures are 50 °F and rising.

Spray markings at 25-mil minimum wet film thickness or at a rate of 71 square feet per gallon.

634.07 Epoxy Pavement Markings (Type D). Apply epoxy when pavement and air temperatures are 35 °F and rising. Heat components according to the manufacturer’s recommendations. Apply at a 25-mil minimum dry film thickness or at a rate of 71 square feet per gallon.

634.08 Thermoplastic Pavement Markings (Type H). Apply thermoplastic when pavement and air temperatures are 50 °F and rising. Heat thermoplastic according to the manufacturer’s recommendations.

Apply an epoxy resin primer and sealer according to the thermoplastic manufacturer’s recommendations if placing markings on pavements more than 2-year old, oxidized, or having exposed aggregates. Allow the primer and sealer to dry.

For edge lines, apply thermoplastic at 60-mil dry film thickness. For other lines, apply thermoplastic to a 90-mil dry film thickness.

634.09 Preformed Pavement Markings (Type J). Use preformed marking tape containing retroreflective beads. Install to form a durable, weather resistant bond to the pavement. Apply preformed markings according to the manufacturer’s recommendations.

634.10 Methyl Methacrylate Pavement Markings (Type L). Apply a two-component methyl methacrylate marking at a minimum thickness of 60 mils for longitudinal markings and 120 mils for transverse markings and symbols. Apply markings when pavement and air temperature are between 40 °F and 105 °F. Apply according to the manufacturer’s recommendations.

634.11 Pavement Markers. Install raised or recessed pavement markers when the pavement and air temperatures are 50 °F and rising. Apply pavement markers with an epoxy resin adhesive according to the manufacturer’s recommendations when the pavement is dry. Space the markers according to the MUTCD and as shown in the plans.

634.12 Acceptance. Material for permanent pavement markings and markers will be evaluated under Subsections 106.02 and 106.03.

Applying permanent pavement markings and markers will be evaluated under Subsections 106.02 and 106.04.

Measurement

634.13 Measure the Section 634 pay items listed in the bid schedule according to Subsection 109.02 and the following as applicable:

When two coats of markings are required, measure each coat.

When measuring pavement markings by the linear foot or mile, measure the length of line applied along the centerline of each line applied regardless of color. Measure broken or dotted pavement lines from end to end of the line including gaps. Measure solid pavement lines from end to end of each continuous line. Measure line quantities based on a 4-inch-wide line. For line widths greater than 4 inches, adjust the measured length of line in the ratio of the required width to 4 inches.

When measuring pavement markings by the square foot, measure the number of square feet of line, symbol, or letter marking based on the marking area shown in the plans. If not shown, measure the area of each marking in place to the nearest square foot.

Payment

634.14 The accepted quantities will be paid at the contract price per unit of measurement for the Section 634 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section.

See Subsection 109.05.
