4 TechCrete History

5 What is TechCrete? TechCrete is the most advanced flexible concrete solution for highway and airport pavement rehabilitation! 5

6 TechCrete Composition Binder- Polymer-modified resin and oils to better resist shoving and cracking. Aggregate designed to provide mass and stability for compression resistance and to meet load bearing requirements, while still allowing the material to flow. 6

7 TechCrete Products TechCrete R TechCrete R contains finer aggregate and is used for repairs up to ¾ inch (20mm) deep. TechCrete TBR TechCrete TBR contains larger aggregate particles and is used for repairs from ¾ inch to 8 inches (20 to 200mm) deep. This is the most frequently used TechCrete product. 7

8 TechCrete Attributes w/video Pre-blended mix Produces no compressive or tensile stress on the surrounding pavement Flowable/Pourable Aggregate Filled/Extendable Load Bearing Resistance Flexible Excellent Adhesion Voidless Waterproof 8

9 Where to Use TechCrete TechCrete products provide solutions for concrete distresses that include but are not limited to: Wide Cracks Longitudinal Cracks Transverse Cracks D Cracking Corner Slab Breaks Pavement Blow-ups Joint Failures Spalls Potholes Pop-outs 9

15 Benefits of TechCrete 15

16 Benefits of TechCrete TechCrete is easily installed and can be opened to traffic within an hour TechCrete waterproofs PCC pavement and is chemical-resistant 16

17 Installation - Equipment Use only an indirectly-heated Patcher with sufficient agitation.

18 Installation - Preparation Mark the perimeter of the areas to be repaired Remove the defective pavement

19 Installation - Preparation Clean and dry the repair area with a hot air lance. Ensure the pavement temperature exceeds 40 F (4 C) during application

20 Installation - Preparation Prime the entire repair area Install TechCrete 375 F-400 F 2 lifts if depth is greater than 2 ½.

25 FIBRECRETE FIBRECRETE provides an impervious, color-matched hard-wearing finish. The finished patch has good tensile strength, flexibility, and resists compression and wheel tracking. FIBRECRETE is designed to replace traditional cementitious repairs which are prone to failure due to their stiffness. the only proven durable patch

26 FIBRECRETE B and G FIBRECRETE B (black) is a hot-applied polymer modified asphalt base material containing mineral fillers, chopped fibers, sand and graded granite aggregates. FIBRECRETE B is supplied in 50 lbs blocks. FIBRECRETE G (grey) is a hot-applied synthetic polymer modified resin compound. The grey formulation performs equal to FIBRECRETE B, and meets or exceeds the same performance specifications. Fibrecrete G is a supplied in 50 lb melt bags. the only proven durable patch

28 Purpose-Built Equipment

29 FIBRECRETE solution Deep Repair Method The defective area is removed to the required width and depth and where necessary the existing joint sealing compound is removed. Loose material and debris is mechanically swept and removed from the site. The area is thoroughly cleaned with controlled use of hot compressed air. Where the repair depth is greater than 2, hot applied Fibrecrete material is bulked out with larger aggregate. The remaining recess is then filled with Fibrecrete compound to finish flush with the pavement surface. While Fibrecrete is still molten a dressing of pre-heated high PSV aggregate is applied. IH Fast installation minimizes costly traffic management and aircraft movement disruption. The finished repair can withstand very high traffic loading within minutes of application. The repair is totally impervious to water and salts thus arresting further deterioration.
