Stamark Liquid Pavement Marking Series 1500

Transcription

1 3 Stamark Liquid Pavement Marking Series 1500 Market Test Product Bulletin 1500 March 2004 Replaces PB 1500 dated February 2002 Description 3M Stamark Liquid Pavement Marking (LPM) Series 1500 is designed for intersection pavement markings. The binder for series 1500 pavement marking is a two-component liquid marking system that quickly cures to hardness after application. The quick cure time of the product is independent of air and road surface temperature, allowing for application in cool weather when other products would require longer traffic closures or detours. Reflectivity is provided by glass beads dropped onto the binder just after it is coated and before it hardens. Series 1500 liquid pavement marking resists color change from UV exposure, and is suitable for application on properly prepared asphalt and Portland cement concrete. The material is packaged in 5-gallon containers for ease of handling and loading into equipment. Series 1500 can be used for crosswalks, stop bars, symbols and legends and other transverse markings. Product Features Retroreflective. Will not yellow due to ultraviolet exposure. Reliable adhesion to properly prepared asphalt cement concrete or Portland cement concrete surfaces. Manufactured without the use of heavy metals, lead chromate pigments or other, similar, lead containing chemicals. Low temperature application. Quick cure time. Available in white, yellow and yellow green.* No significant VOCs.

3 Application Requirements The applicator of the markings is responsible for meeting the following requirements: Binder Coating Thickness and Corresponding Application Rates Surface Type New Concrete Surface 2 New Asphalt Surface (Standard Asphalt Mix) Existing Smooth Asphalt or Concrete Mix Rough, Irregular Surfaces such as Open Grade Friction Course (OGFC), Stone Matrix Asphalt (SMA) Rough Surfaces after grinding and surface preparation 3 Recommended Liquid Pavement Marking Thickness (1 inch=1000 mils) and Rates of Application mils (64 square feet per gallon) mils (80-64 square feet per gallon) 1 Application rates calculated using a conversion of 231 cubic inches per US liquid gallon. 2 Use thicker binder (25 mils) on new concrete surfaces with heavy tines. 3 Vary mil thickness relative to surface roughness - rougher surfaces require thicker coating. Glass Bead Application Rates Glass beads shall be applied at the rates shown in the table below. Units Glass Beads 4 Grams per square foot 54 grams/ft 2 Pounds per square foot lb/ft 2 Pounds per gallon - 20 mils, 9.5 lbs./gal 80 theoretical square feet per gallon Pounds per gallon - 25 mils, 7.6 lbs./gal 64 theoretical square feet per gallon 4 Application rates calculated using a conversion of grams per pound. Marking Dimensions In accordance with the Manual of Uniform Traffic Control Devices and the project plans. Proportioning and Mixing Continuous proportioning at 2 volumes of Part A to every 1 volume of Part B and adequate mixing so that markings are hardened throughout and are free of soft and uncured or blackened areas. Placement of Beads Beads must be dropped in the polyurea binder so that their upper exposed portions are free of binder material. Control of Overspray The markings must not exhibit excessive overspray. 3

4 Weather and Pavement Conditions Dry weather only. Air temperature of at least 40 F. Road surface completely dry. Road surface free of dirt, sand, dust, oil, grease and all other contaminants. Curing compound and latents removed from new Portland concrete surfaces. All road surfaces that have been exposed to traffic must be prepared by grinding, sandblasting, or shot blasting prior to application of LPM Series Preparation must remove all existing markings, dirt, automotive fluids, and other contaminants, AND remove a layer of the existing pavement to expose a fresh, new pavement surface. After preparation is complete and prior to application of new markings, the surface shall be blown free of loose debris and dust using a high-pressure blower from a compressed air source. If existing pavement markings are present on the roadway, remove entire marking from the surface by sandblasting, grinding, or other suitable method. A minimum of 90% of the road surface under the existing marking must be exposed prior to LPM Series 1500 application. Additional grinding to remove a layer of the pavement surface must be completed over the entire surface where LPM Series 1500 will be applied. After grinding, if oil-drip zones are visible, more grinding is recommended. See Information Folder 5.19 for additional application guidelines. Equipment Application equipment consists of a mobile, truck mounted or palletized self-contained pavement marking machine, specifically designed to apply two-component liquid materials through a spray gun. Application machines accommodate mixing of the two liquid materials at a 2-to-1 volumetric mixing ratio. Several companies manufacture pavement marking application equipment with airless spray systems that will apply LPM Series The equipment shall be capable of heating and maintaining the Part A and Part B liquid components at separate, controllable temperatures to enable proper pump loading, mixing and spraying of the material. Storage Store liquid pavement marking binder and crosslinker in a cool, dry, well ventilated area indoors, 40 F F (5 C - 40 C). Use within six (6) months of receipt. Clean up of empty containers is the responsibility of the contractor. For more information see 3M Stamark Liquid Pavement Marking Safe Handling Procedures brochure. If the Part B liquid pavement marking container is exposed to high heat for an extended period, it can be pressurized and possibly rupture explosively.
