Physical Properties5.1 In general, physical properties outline characteristicsbest suited for skateboard, roller blade, and BMX activities.5.2 Concrete FinishThe concrete surface should provide asmooth and nonslip surface characteristic (see ACI 302.1R-04Clas

35、s 9 Finish).5.3 Surface Flatness and LevelnessTolerances shouldconform to the requirements set forth in ACI 11790. Adiscussion of concrete flatness/levelness is given in the com-mentary to ACI 11790.5.3.1 Flatness and levelness requirements should be de-scribed in bid documents. Methods for defining

36、 flatness andlevelness should be in accordance with ACI 11790 and TestMethod E1155. The flatness values should control local surfacebumpiness in accordance with Test Method E1155. The level-ness values should control local conformance to design grade(see Test Method E1155).5.3.2 PrecautionsConcrete

37、surface tolerance specificationand measurement procedures should be pre-bid determined.Tolerances should be defined based on what can be reasonablyexpected from a given construction method. The concreteflatness/levelness constitutes a potential issue, the followingprecautions are suggested:5.3.2.1 T

38、he exact meaning of the flatness/levelness require-ment and the exact method and time of measurement todetermine compliance should be established before beginningconstruction.5.3.2.2 The contractor or fabricator should confirm anability to satisfy the concrete surface tolerance requirement byprofili

39、ng previous installations or specimens.5.3.2.3 Where feasible, test slabs or specimens should beinstalled or supplied to verify the effectiveness of proposedfabrication procedures under actual job conditions. Ifnecessary, methods and procedures should then be modified forthe actual job installation

40、based on these results. The accep-tance of the test slab or specimen by the owner as to tolerancesand surface finish should clarify requirements for the projectslab and becomes the project “Exemplar/Benchmark.”5.3.2.4 The exact remedy to be applied to every possibleconcrete surface tolerance deficie

41、ncy should be confirmed withthe designer.5.3.3 Levelness and flatness design in concrete skateparkconstruction should define acceptable tolerances for radii ofcurved surfaces, flatness values on a radius should be similar tothose of a flat surface. This applies to all elevation changetolerances, ban

42、ks, ledges, and so forth.5.4 Expansion Joints and Control Joints:5.4.1 Expansion joints should be placed where they are leastlikely to interfere with a wheel. Careful consideration toexpansion joints location must be given, using the flow ofskaters as critical design criteria.5.4.2 Unfilled cut cont

43、rol joint must not exceed18 of aninch.5.4.3 Filled Control JointSize of control joint is notimportant. It must be a rigid control joint filler, which must beflush with the skating surface and close the joint completely.5.4.4 Tooled Control JointsJoints should be placed wherethey are least likely to

44、interfere with skate wheels, and a cutcontrol joint is not possible.5.5 Consolidation and Compaction of Concrete AroundExposed Steel MaterialsThe placement of concrete on slopedradii or any areas incorporating a change in elevation is criticalto the stability of the exposed steel material or concret

45、e coping.The difficulty of achieving proper consolidation around thesteel material and their reinforced attachments through the useof standard air removal consolidation techniques can lead toslumping and the creation of an air pocket around the steelmaterial, which may not be visible during construc

46、tion andmay result in concrete failure on the riding surface. See Section8.3 of ACI 302.1R-04 and ACI 309R for detailed discussion.6. Other Requirements6.1 Protective Edging:6.1.1 If protective edging/surface is used, it shall be flushwith the finished riding surface. It shall be strong enough topro

47、tect the surface from damage and excessive wear due toprolonged use.6.1.2 When protective edging is used as protection againstbike pegs, it shall extend a minimum of 4.0 in. behind thecoping, and be flush with the riding surface.6.2 Coping shall protrude 0.25 6 0.125 in. above the restingdeck and sh

48、all protrude 0.25 + 0.25 in. or 0.125 in. aboveriding surfaces (see Fig. 1).6.2.1 The outside radius of coping shall be a minimum of1.18 in. or 30 mm.6.3 Gaps or transitions between riding surfaces intended tobe in the same plane shall not exceed 0.188 in. in any direction.7. Owners Responsibility7.

49、1 SignageSkatepark signage shall be provided by theowner/operator for installation on a signboard at the skatepark.7.2 Skatepark signage, free standing or fixed fence, mustcomply with the following:7.2.1 Convey safety information to the user and to thoseproviding parental or guardian supervision.7.2.2 Indicate that adult supervision of minors is or is notpresent.7.2.3 Indicate the owner-operator emergency telephonenumbers.FIG. 1 Coping ExampleF2480 06 (2017)37.2.4 Indicate emergency telephone numbers for medical,ambulance, and police.7
