1 Helping to Save Lives and Protect Infrastructure

2 What is SafeLane ® surface overlay? Two part epoxy and unique aggregate overlay designed to provide two major benefits –Safety –Infrastructure Protection

3 Helping to Save Lives and Protect Infrastructure Safety Accident Prevention 70% of U.S. deaths related to ice and snow occur in vehicles – Source: Virginia Department of Emergency Management Preventing slick conditions from occurring during winter driving can reduce collisions by up to 75% - Source: C-SHRP Technical Brief # 20 July 2000

4 Helping to Save Lives and Protect Infrastructure Safety Accident Prevention Helps prevent black ice from forming Helps prevent frozen precipitation from bonding to the road surface, reducing slick conditions Provides longer residual effect for deicing/anti-icing products

5 Helping to Save Lives and Protect Infrastructure Safety Increased Friction Year round friction course gives added safety SafeLane ® surface overlay provided superior friction versus asphalt and concrete overlays

6 Helping to Save Lives and Protect Infrastructure Infrastructure Protection Epoxy provides barrier that helps prevent water and chloride intrusion Can help extend the life of both existing and new infrastructure

7 Helping to Save Lives and Protect Infrastructure SafeLane ® technology Field Example #1 Early signs of spalling concrete

10 Helping to Save Lives and Protect Infrastructure Overlay installation methods Epoxy Mixing Manual Automatic mixers Aggregate Manual Tow-behind spreader box(Cargill modified) Mobile chip spreader

11 Helping to Save Lives and Protect Infrastructure Gradation% Passing 3/8 (9.5 mm) #4 (4.75 mm)30-70 #8 (2.36 mm)0-15 Aggregate Specifications

12 Helping to Save Lives and Protect Infrastructure CourseEpoxy Rate Gal/100 sq. ft. (liters/sq. meter) Aggregate lbs/ sq. ft.* (kg/ sq. meter) 1 st 2.0 to 4.0 (0.8 to 1.6)1-2 (4.9 to 9.75) 2 nd 6.0 to 8.5 (2.4 to 3.4)3-4 (14.6 to 19.5) *Application of aggregate shall be of sufficient quantity to completely cover the epoxy Application Rates - Double Pass Method

13 Helping to Save Lives and Protect Infrastructure Application Conditions - Double Pass Method (Approximate Cure Times) CourseAverage Temperature of Deck, Epoxy, and Aggregate Component in °F (°C) (16-18) (18-21) (21-23) (24-26) (27-29) *85+ (29+) 1 st 4 hr3 hr2.5 hr2 hr1.5 hr1 hr 2 nd 6.5 hr5 hr4 hr3 hr 3 hrs

14 Helping to Save Lives and Protect Infrastructure 1. Clean 2. Install test patches over cleaned surface3. Core drill 4. Adhere pull disks to overlay surface 5. Measure Adhesion 6. Successful Test

15 Helping to Save Lives and Protect Infrastructure Recap Safety Automatic Anti-icing helps reduce accidents Reducing accidents helps save lives Reducing accidents helps reduce costs Reduce your environmental footprint Infrastructure preservation Seals pavement and helps prevent intrusions Extends the life of your investment Allows for valuable maintenance dollars to be spent elsewhere
