FIBERGLASS TRACK RAIL SET IN CONCRETE TROUGH

PART 1 – GENERAL

1.1 SUMMARY

PROVIDE LABOR, MATERIALS, EQUIPMENT, AND INCIDENTALS NECESSARY TO INSTALL EXTRUDED FIBERGLASS/COMPOSITE TRACK RAIL IN FORMED CONCRETE TROUGHS, INCLUDING SURFACE PREPARATION, ALIGNMENT, TEMPORARY SUPPORTS, GROUT BEDDING, AND SEALING OF EXPOSED TOP JOINTS. PRIMARY ATTACHMENT SHALL BE BY GROUT BEDDING SYSTEM, NOT BY SEALANT ALONE. HIGH-STRENGTH EPOXY GROUT PRODUCTS SUCH AS SIKADUR-42 GROUT-PAK ARE DESCRIBED BY SIKA AS 100% SOLIDS, MOISTURE-TOLERANT EPOXY GROUTING

SYSTEMS USED FOR PRECISION GROUTING UNDER EQUIPMENT AND UNDER CRANE RAILS.

1.2 PERFORMANCE REQUIREMENTS

A. INSTALLED RAIL SHALL BE FULLY SUPPORTED, TRUE TO LINE AND GRADE, AND CAPABLE OF TRANSFERRING IMPOSED SERVICE LOADS INTO

THE CONCRETE TROUGH WITHOUT VOIDS OR UNSUPPORTED BEARING POINTS.

B. PROVIDE AN ELASTOMERIC RAIL GROUT RECOMMENDED BY THE MANUFACTURER FOR ADHESION TO BOTH RAIL AND CONCRETE WHILE

MAINTAINING LINE AND GRADE.

C. EXPOSED TOP JOINTS, WHERE REQUIRED, SHALL BE SEALED WITH AN ELASTOMERIC POLYURETHANE SEALANT COMPATIBLE WITH BOTH

CONCRETE AND FIBERGLASS/COMPOSITE SUBSTRATES.

PART 2 – PRODUCTS

2.1 GROUT BEDDING MATERIALS

A. FLEXIBLE GROUT OPTION: PROVIDE ELASTOMERIC RAIL GROUT DESIGNED FOR ADHESION TO RAIL AND CONCRETE WHILE MAINTAINING LINE AND GRADE, WITH VIBRATION-DAMPENING CHARACTERISTICS; BASIS OF DESIGN: STONHARD ELASTOMERIC GROUT OR APPROVED EQUAL.

2.2 JOINT SEALANT

PROVIDE ONE-COMPONENT OR APPROVED EQUIVALENT POLYURETHANE ELASTOMERIC SEALANT FOR SEALING EXPOSED TOP JOINTS AFTER GROUT CURE; BASIS OF DESIGN: SIKAFLEX NP 1 FOR NON-SAG JOINTS OR SIKAFLEX SL 1 FOR SELF-LEVELING HORIZONTAL JOINTS, AS

APPLICABLE.

2.3 ACCESSORIES

PROVIDE SHIMS, TEMPORARY SUPPORTS, ALIGNMENT FIXTURES, BOND-BREAKERS, BACKER ROD WHERE NEEDED, PRIMERS IF REQUIRED BY SEALANT MANUFACTURER, AND ALL MISCELLANEOUS ITEMS NECESSARY FOR A COMPLETE INSTALLATION IN ACCORDANCE WITH THE RAIL AND GROUT MANUFACTURER’S WRITTEN INSTRUCTIONS. MANUFACTURER COMPATIBILITY REQUIREMENTS SHALL GOVERN FINAL PRODUCT

SELECTION.

PART 3 – EXECUTION

3.1 EXAMINATION AND PREPARATION

A. VERIFY CONCRETE TROUGH DIMENSIONS, CLEANLINESS, DRYNESS, AND SOUNDNESS PRIOR TO INSTALLATION.

B. REMOVE LAITANCE, DUST, CURING COMPOUNDS, LOOSE MATERIAL, OILS, AND CONTAMINANTS THAT WOULD IMPAIR BOND.

C. CONFIRM THE FIBERGLASS/COMPOSITE RAIL MANUFACTURER PERMITS THE PROPOSED GROUT TYPE. USE ELASTOMERIC GROUT

3.2 INSTALLATION

A. SET RAIL TO REQUIRED ELEVATION, ALIGNMENT, AND GAUGE USING TEMPORARY SUPPORTS AND CONTROL POINTS.

B. PLACE GROUT CONTINUOUSLY BENEATH AND AROUND RAIL IN ACCORDANCE WITH GROUT MANUFACTURER’S INSTRUCTIONS TO ACHIEVE

FULL BEARING WITH NO VOIDS.

C. DO NOT USE SEALANT AS THE PRIMARY ATTACHMENT MEDIUM. PRIMARY RAIL SUPPORT AND ATTACHMENT SHALL BE BY THE SPECIFIED

GROUT BEDDING SYSTEM.

D. AFTER GROUT CURE, CLEAN AND SEAL EXPOSED TOP JOINT, IF REQUIRED, WITH POLYURETHANE SEALANT. TOOL SEALANT TO PROVIDE A

NEAT, WATERTIGHT JOINT PROFILE.

3.3 FIELD QUALITY CONTROL

A. VERIFY FINAL RAIL ALIGNMENT, BEARING SUPPORT, AND JOINT CONDITION.

B. REPLACE OR REPAIR RAILS EXHIBITING MISALIGNMENT, VOIDED GROUT SUPPORT, OR SEALANT FAILURE.

C. PROTECT INSTALLED WORK FROM LOADING AND TRAFFIC UNTIL GROUT AND SEALANT ACHIEVE MANUFACTURER-REQUIRED CURE.
