Materials4.1 GeneralAll materials used shall fulfill the sport-specific requirements for skatepark facilities.4.2 Steel ElementsAll exposed steel shall be i
25、nherentlycorrosion resistant or be provided with a corrosion resistantcoating.4.3 Concrete:4.3.1 All concrete should consider the following, which isnot necessarily all-inclusive: compressive strength, flexuralstrength, or both, and finishability; maximum size, grading, andtype of coarse aggregate;
26、grading and type of fine aggregate;combined aggregate grading; air content of concrete, if appli-cable; slump of concrete; water-cement ratio or water-cementitious material ratio; and preplacement soaking require-ment for lightweight aggregates; and should conform to but arenot limited to the requir

31、s outlined in SpecificationC1116 or ACI 302.1R-04-26.4.6 Other MaterialsUtilization of other materials is ad-missible.5. Physical Properties5.1 In general, physical properties outline characteristicsbest suited for skateboard, roller blade, and BMX activities.5.2 Concrete FinishThe concrete surface
32、should provide asmooth and nonslip surface characteristic (see ACI 302.1R-04Class 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 lev
33、elness requirements should be de-scribed in bid documents. Methods for defining 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 loca
34、l conformance to design grade(see Test Method E1155).5.3.2 PrecautionsConcrete surface tolerance specificationand measurement procedures should be pre-bid determined.Tolerances should be defined based on what can be reasonablyF2480 06 (2012)2expected from a given construction method. The concretefla
35、tness/levelness constitutes a potential issue, the followingprecautions are suggested:5.3.2.1 The 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 fabr
36、icator should confirm anability to satisfy the concrete surface tolerance requirement byprofiling 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 conditio
37、ns. If neces-sary, methods and procedures should then be modified for theactual job installation based on these results. The acceptance ofthe test slab or specimen by the owner as to tolerances andsurface finish should clarify requirements for the project slaband becomes the project “Exemplar/Benchm
38、ark.”5.3.2.4 The exact remedy to be applied to every possibleconcrete surface tolerance deficiency 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 s
39、hould be similar tothose of a flat surface. This applies to all elevation changetolerances, banks, 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 locat
40、ion must be given, using the flow ofskaters as critical design criteria.5.4.2 Unfilled cut control 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 joi
41、nt completely.5.4.4 Tooled Control JointsJoints should be placed wherethey are least likely to interfere with skate wheels, and a cutcontrol joint is not possible.5.5 Consolidation and Compaction of Concrete AroundExposed Steel MaterialsThe placement of concrete onsloped radii or any areas incorpora
42、ting a change in elevation iscritical to the stability of the exposed steel material or concretecoping. The difficulty of achieving proper consolidation aroundthe steel material and their reinforced attachments through theuse of standard air removal consolidation techniques can leadto slumping and t
43、he creation of an air pocket around the steelmaterial, which may not be visible during construction 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/surf
44、ace is used, it shall be flushwith the finished riding surface. It shall be strong enough toprotect 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
45、with the riding surface.6.2 Coping shall protrude 0.25 6 0.125 in. above the restingdeck and shall 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 intende
46、d tobe in the same plane shall not exceed 0.188 in. in any direction.7. Owners Responsibility7.1 Signage:7.1.1 Skatepark signage shall be provided by the owner/operator for installation on a signboard at the skatepark.7.2 Skatepark signage, free standing or fixed fence, mustcomply with the following
47、: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.7.2.4 Indicate emergency telephone numbers for medical,ambulance, and p
48、olice.7.2.5 Indicate any applicable regulations regarding the useof safety gear.7.2.6 Indicate there is an inherent risk in the participation ofskatepark activities. Users of skateparks, by participation,accept the risks inherent in such participation of which theordinary prudent person is or should
49、 be aware. Users have aduty to exercise good judgment and act in a responsible mannerwhile using the skatepark and obey all oral or written warnings,or both, prior to or during participation, or both.7.2.7 Indicate users have a duty not to participate in or onany skatepark while under the influence of drugs or alcohol.7.2.8 Shall be readily visible to the intended viewers/usersas in accordance with Section 8.2 and Annex B3.28: B3.29 andB3.2.11-13 of ANSI 2535.4.7.2.9 Sign type shall be the same style as in accordance withANSI 2535.4B.8.
