    36、 should conform to the requirements set forth in ACI 11790. A discussion ofconcrete flatness/levelness is given in the commentary to ACI 11790.5.3.1 Flatness and levelness requirements should be described in bid documents. Methods for defining flatness and levelnessshould be in accordance with ACI 1

    37、1790 and Test Method E1155. The flatness values should control local surface bumpiness inaccordance with Test Method E1155. The levelness values should control local conformance to design grade (see Test MethodE1155).5.3.2 PrecautionsConcrete surface tolerance specification and measurement procedure

    38、s should be pre-bid determined.Tolerances should be defined based on what can be reasonably expected from a given construction method. The concreteflatness/levelness constitutes a potential issue, the following precautions are suggested:5.3.2.1 The exact meaning of the flatness/levelness requirement

    39、 and the exact method and time of measurement to determinecompliance should be established before beginning construction.5.3.2.2 The contractor or fabricator should confirm an ability to satisfy the concrete surface tolerance requirement by profilingprevious installations or specimens.5.3.2.3 Where

    40、feasible, test slabs or specimens should be installed or supplied to verify the effectiveness of proposed fabricationprocedures under actual job conditions. If necessary, methods and procedures should then be modified for the actual job installationbased on these results. The acceptance of the test

    41、slab or specimen by the owner as to tolerances and surface finish should clarifyrequirements for the project slab and becomes the project “Exemplar/Benchmark.”5.3.2.4 The exact remedy to be applied to every possible concrete surface tolerance deficiency should be confirmed with thedesigner.5.3.3 Lev

    42、elness and flatness design in concrete skatepark construction should define acceptable tolerances for radii of curvedsurfaces, flatness values on a radius should be similar to those of a flat surface. This applies to all elevation change tolerances,banks, ledges, and so forth.5.4 Expansion Joints an

    43、d Control Joints:5.4.1 Expansion joints should be placed where they are least likely to interfere with a wheel. Careful consideration to expansionjoints location must be given, using the flow of skaters as critical design criteria.5.4.2 Unfilled cut control joint must not exceed 18 of an inch.5.4.3

    44、Filled Control JointSize of control joint is not important. It must be a rigid control joint filler, which must be flush withthe skating surface and close the joint completely.5.4.4 Tooled Control JointsJoints should be placed where they are least likely to interfere with skate wheels, and a cut con
