for Highway Construction Page 438 of 71 5 SECTION 575 – TEXTURED CONCRETE SURFACE
575.01 Description.
Texture exposed concrete surfac es with plastic form liner patterns specified or other Engineer -approved methods.
575.02 Materials.
Not specified.
575.03 Construction Requirements.
Provide plastic form liner patterns bonded to the forms or alternate texturing methods for Engineer approval at least 2 weeks before concrete placement . Alternate texturing methods will require a field mock -up panel to ensure uniformity. Ensure inside form dimensions provide for full plan dimensions plus the t exturing thickness. Attach and treat plastic form liners with a release agent and then remove in accordance with the manufacturer's written instructions. Align the grooves in the form liner panels at construction joints. Conceal const ruction joints in the textured concrete surface.
575.04 Method of Measurement.
The Engineer will measure acceptably completed work by the square yard.
575.05 Basis of Payment .
The Department will pay for accepted quantit ies at the contract unit price as follows: Pay Item Pay Unit Textured Concrete Surface ..................................................................... SY The cost for materials , form liner, form placement , removal, and finishing work is incidental . for Highway Construction Page 439 of 71 5 SECTION 576 – GLASS FIBER REINFORCED POLYMER (GFRP) REINFORCEMENT
576.01 Description.
Provide and place glass fiber reinforced polymer (GFRP) as specified.
576.02 Materials.
Provide GFRP reinforcement meeting ASTM D79 57/D7957M.
1.Bridge Applications: Provide GFRP reinforcement that is deformed and/or sand coated.
2.Dowel Bar Applications in Concrete Pavement :
a.Provide GFRP reinforcement that is smooth for dowel bar applications. Dowel size will be one size larger than the required size for steel dowels.
b.Meet the requirements of AASHTO T 253 and ASTM D 7705.
c.All GFRP requir es an appropriate and approved bond -breaking material prior to installation of the concrete pavement , unless the manufacturer can demonstrate that pull -out forces, as determined by AASHTO T 253 do not require it.
d.The coating, cladding, or surface finish of all dowel bars must be continuous and uniform over the lateral surface of the dowel and must resist wear (due to abrasion resulting from joint movements) that would reduce corrosion resistance, increase joint restraint or reduce st ructural capacity to unacceptable levels.
e.Any change in material composition or dimension of the dowels or dowel assembly are subject to complete testing by the manufacturer prior to approval.
A.Submittals. Provide written certification that the GFRP reinforcement meets this specification. The written certification must list the identifying lot information and test values and test procedures used to determine the physical properties of the GFRP reinforcement. Provide certifications bearing the notarized signature of a manufacturer’s representative having quality control responsibility. Identify each bundle of GF RP reinforcement with a durable tag displaying the corresponding lot numbers.
B.Repa ir Material. Comply with the bar manufacturer’s requirements for the material used to repair the cut ends of GFRP reinforcement . Perform all repairs of cut ends at the GFRP reinforcement manufacturer's plant unless otherwise approved.
576.03 Construction Requirements.
A.Material Handling. When handling G FRP reinforcement, use equipment that avoids damaging or abrading the GFRP reinforcement. Do not drop or drag the GFRP reinforcement.
