Art. 582.06 Portland Cement Mortar Fairing Course The established average target density shall apply throughout the project unless there are changes in mix materials or an appreciable change in the job mix formula. The Engineer may require a new average target density to be established if there is reason to believe that the mixture being placed is not the same as the mixture used to determine the target density.
582.06 Acceptance Tests. Acceptance tests will be performed once the
average target density has been established. At least one acceptance test will be taken for each 200 ft (60 m) or portion thereof of bridge deck per paver pass. Acceptance tests on material placed in a single day shall average 98 percent of the established average target density with no one test being below 95 nor more than 103 percent of the established target density. If the above requirements for average or individual density tests cannot be obtained, placement of additional material will be discontinued until the cause of the failure is investigated and corrected. Acceptance tests will be performed with the same nuclear equipment used to establish the average target density. Acceptance tests will be for one-minute duration and the area to be tested shall be prepared with mineral filler prior to testing.
582.07 Method of Measurement. This work will be measured for payment
according to Article 406.13.
582.08 Basis of Payment. This work will be paid for according to
Article 406 — 14.
SECTION 583. PORTLAND CEMENT MORTAR FAIRING COURSE
583.01 Description. This work shall consist of placing portland cement
mortar along precast, prestressed concrete bridge deck beams as required for fairing out any unevenness between adjacent deck beams prior to placing of waterproofing membrane and surfacing.
583.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Portland Cement ............................................................................ 1001.01(a)
b.Fine Aggregate .................................................................................. 1003.02
c.Water ...................................................................................................... 1002 CONSTRUCTION REQUIREMENTS
583.03 General. This work shall only be performed when the air temperature
is 45 °F (7 °C) and rising. The mixture for portland cement mortar shall consist of three parts sand to one part portland cement by volume. The amount of water shall be no more than that necessary to produce a workable, plastic mortar. Prior to placement of the mortar fairing course, all areas where unevenness occurs between the deck beams shall be prepared according to Article 503.09(b). Grouting of Anchor Rods And Bars Art. 584.04 The mortar shall be placed to the thickness necessary to eliminate unevenness between the beams. It shall be placed to form a smooth even surface from the higher beam edges to the lower surface. The mortar finished surface shall slope not less than 1:3 (V:H) and shall be feathered smoothly into the deck beam surfaces. The finish shall be free of depressions or sharp edges. The mortar shall be cured for a period of not less than three days by the wetted burlap method according to Article 1020.13(a)(3). Curing shall commence as soon as practicable after mortar placement.
583.04 Method of Measurement. This work will be measured for payment in
feet (meters) along the beam edges.
583.05 Basis of Payment. This work will be paid for at the contract unit price
per foot (meter) for PORTLAND CEMENT MORTAR FAIRING COURSE. SECTION 584. GROUTING OF ANCHOR RODS AND BARS
584.01 Description. This work shall consist of drilling and grouting anchor
rods and bars into hardened concrete.
584.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Chemical Adhesive Resin System .......................................................... 1027 CONSTRUCTION REQUIREMENTS
584.03 General. Holes shall be drilled in the concrete to 1/4 in. (6 mm) larger
in diameter than the diameter of the anchor rods or bars and to the depth shown on the plans. A template or other approved method shall be used to ensure accurate location of the drilled holes. All holes shall be blown free of concrete dust and chips and shall be absolutely dry prior to placing the chemical adhesive. Prior to inserting the anchor rod or bar into the hole, the hole shall be filled approximately 1/3 full of the mixed chemical adhesive. The anchor rod or bar shall be inserted into the partially filled hole and moved up and down several times to ensure total contact of the chemical adhesive with concrete as well as the rod or bar. Additional chemical adhesive shall be extruded to proper concrete level and finished as necessary. The anchor rod or bar shall be aligned to maintain a perpendicular plane. No load shall be applied to the anchors until the chemical adhesive has cured for at least 24 hours.
584.04 Basis of Payment. This work will not be measured or paid for
separately, but shall be considered as included in the unit price bid for the item of construction involved. SECTION 585. RESERVED
