Test Methods and Requirements for Asphalt Base5.1 Type and Com
23、paction:5.1.1 Description and Required PerformanceThe asphaltbase and asphalt wearing course (two layers) for the runningtrack shall conform to the mixes established for road traffic inthe jurisdiction and according to the synthetic surface manu-facturers recommendation of the running track. The asp
24、haltbase and asphalt wearing course (two layers) shall be com-pacted to a minimum of 95 % density for machine finish and90 % density for hand packed areas according to Test MethodD2950. Laboratory tests are performed with local DOT proce-dures. Hand-packed limited to areas not accessible by appro-pr
25、iate equipment.Where the asphalt is permeable to water or ofan open type, vertical drainage is required.5.1.2 Test MethodUse test method as described in TestMethod D2950.5.2 Evenness:5.2.1 Description and Required PerformanceThe runningtrack asphalt base shall be installed so that on a localized lev
26、el,there shall be no bumps or depressions beneath a 3-m straight-edge exceeding 6 mm for a ClassAand B surfaces or 8 mm forClass C surfaces. Depressions beneath a 1-m straightedge shallnot exceed 3 mm for Class A and Class B surface or 4 mm forClass C. There shall be no step-like irregularities grea
27、ter than1 mm in height (see Table 1).5.2.2 Test MethodDrag or regularly place the 3-mstraightedge, advancing by one half the length of the straight-edge for each measurement, on the surface along the length ofthe odd numbered lanes and each runway as a minimum.Additional locations may be tested at t
28、he discretion of the testlaboratory. Both ends of the straightedge should be in contactwith the asphalt surface. At each location use visual observa-tion to determine if a gap exists under the straightedge. Shoulda gap exist, use a calibrated wedge to determine the actual sizeof the gap. For runways
29、, the measurement is regularly taken upthe center of the runway. Where a gap is found, this is recordedon a plan of the facility.5.3 Drainage:5.3.1 Description and Required PerformanceDue to therequirements for evenness, the drainage requirements for theasphalt surface shall be the same as the drain
30、age requirementsfor the synthetic surface as specified in this standard.5.3.2 Test MethodThe asphalt surface is flooded withwater by any number of means, and the time is measured fromthe time the flooding stops for 20 min. Locations with standingwater are noted on a plan of the facility.6. Test Meth
31、ods, Description, and Required Performancefor Newly Installed Synthetic Surfaces6.1 Imperfections:6.1.1 Description and Required PerformanceThe durabil-ity and dynamic performance of the surface may be compro-mised by imperfections such as bubbles, fissures, uncuredareas, delamination, etc. These wi
32、ll not be allowed and must becorrected.6.1.2 Test MethodA visual examination of the surface isconducted and imperfections noted on a plan of the facility. Aphotographic record of imperfections may be used to enhancethe report.6.2 Evenness:6.2.1 Description and Required PerformanceThe runningtrack su
33、rface shall be installed so that on a localized level, thereF2157 092shall be no bumps or depressions beneath a 3-m straightedgeexceeding 6 mm for a Class A and B surfaces or 8 mm forClass C surfaces. Depressions beneath a 1-m straightedge shallnot exceed 3 mm for Class A and Class B surface or 4 mm
34、 forClass C. There shall be no step-like irregularities greater than1 mm in height. Particular attention is to be paid to seams andjoints in the running surface. The intent is to ensure the safetyof the athlete and provide an even running surface.6.2.2 Test MethodDrag or regularly place the 3-mstrai
35、ghtedge, advancing by one half the length of the straight-edge for each measurement, on the surface, along the length ofthe odd-numbered lanes and centerline of each run-up andapproach area as a minimum. Additional locations may betested at the discretion of the test laboratory. Both ends of thestra
36、ightedge should be in contact with the surface. At eachlocation use visual observation to determine if a gap existsunder the straightedge. Should a gap exist, verify that both endsof the straightedge rest on the surface, moving the straightedgeif necessary, then use a calibrated wedge to determine t
37、heactual size of the gap. For runways, the measurement is takenup the center of the runway. For the high jump fan or “D” themeasurement is taken at 5-m intervals along parallel axis intwo directions. Where a gap is found exceeding the maximumfor the class, this is recorded on a plan of the facility.
38、6.3 Thickness:6.3.1 Description and Required PerformanceThe durabil-ity of the surface and the safety of the athlete can be affectedby the thickness of the running track surface. The use of spikesenhances this requirement for a minimum thickness. There willbe specifically designed areas such as in t
39、he javelin runway orother high stress areas where the safety of the athlete and thedurability of the surface will dictate that the thickness begreater than the minimum. This additional thickness shall notaffect the evenness of the surface. The average thickness of therunning track surface shall be a
40、t least 12 mm, and nowhereshall the thickness be less than 10 mm. For Class A the totalarea with a thickness between 10 mm and 10.5 mm shall be nogreater than 5 % of the total surface.6.3.2 Test Method:6.3.2.1 A calibrated three-prong floor depth measuringprobe is used to determine the thickness of
41、the running surface.Care must be taken not to penetrate the asphalt base of therunning surface. This thickness is measured at a minimum of100 locations, starting at the finish line and moving in acounter-clockwise direction taking readings first in the evenlanes (2, 4, 6, 8) and then the odd lanes (
42、1, 3, 5, 7) in the centerof each lane and at regular intervals. For Class A, the intervalis set at every 10 m. Runways shall be probed at 5-m intervalscentered along the length and the “D area” shall be probed ona minimum of 15 locations evenly spaced throughout the areaas a minimum for Class B and
43、Class C, while for Class A, thetest must be performed at 5-m intervals along parallel axes intwo directions. The measurements taken are recorded and thetest points listed in the test report.6.3.2.2 A core (10 to 25 mm in diameter) is removed andmeasured using the following method to make the finalde
44、termination as to the actual thickness. The surface texture ofthe core is abraded with a grade 60 abrasive for approximately50 % of the surface area of the core. The thickness of theabraded area of the core is measured using a thickness gaugeTABLE 1 Performance Requirements for the TestsTest Methoda
