SECTION 09305
PART 1 GENERAL
1. related documents
-
Drawings and general provisions of Contract, including General and Special Conditions and
Division 1 Specifications Section, apply to this Section.
2. DESCRIPTION
-
This Section specifies furnishing and installing surface applied concrete tactile tiles where
indicated, using an exterior grade tactile warning surface tile herein.
3. SUBMITTALS
- Product Data: Submit manufacturer’s literature describing products, installation procedures and
routine maintenance.
- Samples for Verification Purposes: Submit three (3) samples of full size surface applied concrete
tactile tiles of the kind proposed for use.
- Shop drawings are required for products specified showing fabrication details; tile surface profile;
fastener locations; plans of tile placement including joints, and material to be used as well as
outlining installation materials and procedure.
- Material Test Reports: Submit test reports from qualified independent testing laboratory indicating
that materials proposed for use are in compliance with requirements and meet the properties
indicated.
- Maintenance Instructions: Submit copies of manufacturer’s specified maintenance practices for
each type of tactile tile and accessory as required.
4. QUALITY ASSURANCE
- Provide surface applied tactile tiles and accessories as produced by a single
manufacturer.
- Installer’s Qualifications: Engage an experienced Installer certified in writing by tactile flooring
manufacturer as qualified for installation, who has successfully completed tile installations similar
in material, design, and extent to that indicated for Project. Manufacturer’s supervisor shall be
present at all times.
- Americans with Disabilities Act (ADA): Provide tactile warning surfaces which comply with the
detectable warnings on walking surfaces section of the Americans with Disabilities Act (Title 49
CFR TRANSPORTATION, Part 37.9 STANDARDS FOR ACCESSIBLE TRANSPORTATION
FACILITIES, Appendix A, Section 4.29.2 DETECTABLE WARNINGS ON WALKING
SURFACES. In addition products must comply with CALIFORNIA TITLE 24 requirements
regarding patterns, color and sound on cane contact.
- Vitrified Polymer Composite (VPC) surface applied concrete tactile tiles shall be an epoxy
polymer composition with an ultra-violet coating employing aluminum oxide particles in the
truncated domes:
- Water Absorption of Tile when tested by ASTM-D 570 not to exceed 0.35%.
- Slip Resistance of Tile when tested by ASTM-C 1028 the combined wet/dry static coefficient
of friction not to be less than 0.80.
- Compressive Strength of tile when tested by ASTM-D 695-91 not to be less than 18,000
psi.
- Tensile Strength of Tile when tested by ASTM-D 638-91 not to be less than 10,000 psi.
- Flexural Strength of Tile when tested by ASTM - C293-94 not to be less than 24,000 psi.
- Gardner Impact to geometry "GE" of the standard when tested by ASTM-D 5420-93 to
have a mean failure energy expressed as a function of specimen thickness of not less
than 450 in. lbf/in. A failure is noted if a hairline fracture is visible in the specimen.
- Chemical Stain Resistance of Tile when tested by ASTM-D 543-87 to withstand without
discoloration or staining - 1% hydrochloric acid, urine, calcium chloride, stamp pad ink,
gum and red aerosol paint.
- Abrasive Wear of Tile when tested by BYK - Gardner Tester ASTM-D 2386* with
reciprocating linear motion of 37 ± cycles per minute over a 10" travel. The abrasive
medium, a 40 grit Norton Metallite sand paper, was fixed and leveled to a holder. The
combined mass of the sled, weight and wood block is 3.2 lb. Average wear depth shal
not exceed 0.030 after 1000 abrasion cycles measured on the top surface of the dome
representing the average of three measurement locations per sample.
- Fire Resistance: When tested to ASTM E84 flame spread shall be less than 25.
- Accelerated Weathering of Tile when tested by ASTM-G26-95 for 2000 hours shall
exhibit the following result - no deterioration, fading or chalking of surface of tile.
- Vitrified Polymer Composite (VPC) Surface Applied Concrete Tactile Tiles adhered to concrete
shall meet or exceed the following test criteria:
