Test Methods and Requiremen
22、ts for Asphalt BaseType and Compaction5.1 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 o
23、f the running track. The asphaltbase 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 MethodD 2950. Laboratory tests are performed with local DOTprocedures. Hand-packed limited to areas
24、 not accessible byappropriate equipment. Where the asphalt is permeable towater or of an open type, vertical drainage is required.5.2 Test MethodUse test method as described in TestMethod D 2950.Evenness5.3 Description and Required PerformanceThe runningtrack asphalt base shall be installed so that
25、on a localized level,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 i
26、rregularities greater than1 mm in height (see Table 1).5.4 Test MethodDrag or regularly place the 3-m straight-edge, advancing by one half the length of the straightedge foreach measurement, on the surface along the length of the oddnumbered lanes and each runway as a minimum. Additionallocations ma
27、y be tested at the discretion of the test laboratory.Both ends of the straightedge should be in contact with theasphalt surface. At each location use visual observation todetermine if a gap exists under the straightedge. Should a gapexist, use a calibrated wedge to determine the actual size of thega
28、p. For runways, the measurement is regularly taken up thecenter of the runway. Where a gap is found, this is recorded ona plan of the facility.Drainage5.5 Description and Required PerformanceDue to therequirements for evenness, the drainage requirements for theasphalt surface shall be the same as th
29、e drainage requirementsfor the synthetic surface as specified in this standard.5.6 Test MethodThe asphalt surface is flooded with waterby any number of means, and the time is measured from thetime the flooding stops for 20 min. Locations with standingwater are noted on a plan of the facility.6. Test
30、 Methods, Description, and Required Performancefor Newly Installed Synthetic SurfacesImperfections6.1 Description and Required PerformanceThe durabilityand dynamic performance of the surface may be compromisedby imperfections such as bubbles, fissures, uncured areas,delamination, etc. These will not
31、 be allowed and must becorrected.6.2 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.Evenness6.3 Description and Required PerformanceThe runningtrack surface shall be
32、installed so that on a localized level, thereshall 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 forClass C. There shall
33、 be no step-like irregularities greater than1 mm in height. Particular attention is to be paid to seams andF2157022joints in the running surface. The intent is to ensure the safetyof the athlete and provide an even running surface.6.4 Test MethodDrag or regularly place the 3-m straight-edge, advanci
34、ng by one half the length of the straightedge foreach measurement, on the surface, along the length of theodd-numbered lanes and centerline of each run-up and ap-proach area as a minimum. Additional locations may be testedat the discretion of the test laboratory. Both ends of thestraightedge should
35、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 theactual size of
36、 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 axes intwo directions. Where a gap is found exceeding the maximumfor the class, this is recorded on a plan of the facility.Thickness6.5 Des
37、cription and Required PerformanceThe durabilityof the surface and the safety of the athlete can be affected bythe thickness of the running track surface. The use of spikesenhances this requirement for a minimum thickness. There willbe specifically designed areas such as in the javelin runway orother
38、 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 at least 12 mm, and nowher
39、eshall 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.6.6 Test Method:6.6.1 A calibrated three-prong floor depth measuring probeis used to determine the thickness of the running surface. Caremust
40、 be taken not to penetrate the asphalt base of the runningsurface. This thickness is measured at a minimum of 100locations, starting at the finish line and moving in a counter-clockwise direction taking readings first in the even lanes (2, 4,6, 8) and then the odd lanes (1, 3, 5, 7) in the center of
41、 eachlane and at regular intervals. For Class A, the interval is set atevery 10 m. Runways shall be probed at 5-m intervals centeredalong the length and the “D area” shall be probed on aminimum of 15 locations evenly spaced throughout the area asa minimum for Class B and Class C, while for Class A,
42、the testmust be performed at 5-m intervals along parallel axes in twodirections. The measurements taken are recorded and the testpoints listed in the test report.6.6.2 A core (10 mm to 25 mm in diameter) is removed andmeasured using the following method to make the finaldetermination as to the actua
43、l 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 gaugefitted with a 0.01-mm accuracy dial, a plunger flat measuringsurface of 4-mm diameter
44、, and a measurement force between0.8 N and 1.0 N is applied. The measurement is recorded to thenearest 0.1 mm. The difference in thickness between the actualsurface and the abraded surface is calculated and the differencededucted from all of the actual probe measurements and theseTABLE 1 Performance
