Physical Properti
35、es5.1 In general, physical properties outline characteristics best suited for skateboard, roller blade, and BMX activities.5.2 Concrete FinishThe concrete surface should provide a smooth and nonslip surface characteristic (see ACI 302.1R-04Class 9 Finish).5.3 Surface Flatness and LevelnessTolerances
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
45、troljoint is not possible.5.5 Consolidation and Compaction of Concrete Around Exposed Steel MaterialsThe placement of concrete on sloped radiior any areas incorporating a change in elevation is critical to the stability of the exposed steel material or concrete coping.

Other Requirements6.1 Protective Edging:6.1.1 If protective edging/surface is used, it shall be flush with the finished riding surface. It shall be strong enough to protectthe surface from damag
