    • 1980 Railway Technical Research Institute (RTRI) adopted FFU after laboratorial approval in Japan and started the following field tests: Miomotegawa Bridge of Uetsu Line Kanmon Tunnel of Sanyo Line 1985 very good results of field tests FFU sleeper became a approved standard product of JNR 1991 RTRI reported the results of 10 years field tests, which showed almost no deterioration. Application of FFU by private and municipal railways. 1996 RTRI reported the results of 15 years field tests, which indicated that the strength deterioration of 15 year old wooden sleepers will be equal to the strength deterioration of 50 year old FFU sleepers. 2007 Japanese Industrial Standard JIS 1203 2011 RTRI tested FFU sleeper installed in 1980 positive – announced further use for the next 20 years positive to JR Historical development

    • EBA (German Railway Authority), following research was conducted: • Sleeper behavior under the impact of vertical and horizontal loads during the effect of repeated loading. Bedding in ballast track according DIN-EN 13481-3 (wooden sleeper) • Tightening torque tests: determine tensile strength of sleeper screws depending on torque moment. • Sleeper screw extraction tests in accordance with DIN EN 13481-2. (concrete sleeper) • Impact tests to simulate derailment in accordance with German railways technical terms of delivery • Electrical resistance in accordance with DIN EN 13146-5 • Static and dynamic tests of sleepers according to DIN EN 13230-2.(concrete sleeper) Effect of repeated loading test TU Munich September 2008 Elastic Rail Head Deflection Constant Rail Head Deflection right support left support right support left support 2.12 mm 1.71 mm 0.42 mm 0.29 mm After 3 million load cycles
    • Extraction Testing Average extraction force in FFU is 61 kN. Previous extraction tests on sleeper screws on wooden sleepers showed extraction forces of approx. 35 kN. [see Research Report no. 1687, dated June 30.,1997]. Impact Tests A tup (5 kN) with a wheel-flange shaped blade is dropped twice per test from a height of 75 cm onto the impact area. The sleeper is positioned at a slope of 30°. During testing, the sleeper is placed on a 6mm pad. Electrical Resistance Test 1 Test 2 Test 3 Date 10.07.2008 11.07.2008 12.07.2008 Ry [kΩ] 38.9 63.8 57.7 Y [mS/m] 44.4 45.3 44.6 Ky 1.332 1.359 1.338 R33 [kΩ] 51.8 86.7 77.2 Mean value R33 [kΩ] 71,9 Hence, it can be assumed that the required minimum resistance value of R33 ≥ 5 kΩ in accordance with DIN EN 13481-5 was achieved with great certainty. TU Munich September 2008
    • Static Tests at Sleeper Centre Bearing distance was 1.5 m, load plate width was 100 mm. The initial test force was set at 20 kN. Subsequently, the load was gradually increased by 5 kN, while sleeper deflection was registered by four dial indicator gauges. Up to a load of 240 kN, corresponding to a tensile bending strength of 74 N/mm² on the bottom of the sleeper, no crack was detected within the bending area where flexural tension was applied. TU Munich September 2008
    • Static Pressure Test Up to a load of 150 kN no plastic deformation was detected Thus, a load of 300 kN (supporting force) below the rib plate shows a plastic deformation of a maximum of 0.8 mm. Generally the support force for an axle load of 250 kN is 150 kN under the most severe conditions. Static Bending at T = RT and T = - 10°C FFU sleepers were stored in a climate-controlled environment at T=-20°C for two days. The average testing temperature is T = - 10°C . The sleeper shows no signs of embrittlement at low temperatures. A comparison of deformation results does not show any significant differences. Test of temperature dependency of sleeper deformation behavior showed no significant bending differences at T=RT and T=10°C. At T= -10°C there is no noticeable brittleness due to temperature variation. Deformation is predominately purely elastic. TU Munich September 2008
    • Fatigue test on rail seat height 120 mm A load of 150 kN was selected for the fatigue test. This corresponds to an axle load of 250 kN and a train speed V < 200 km/h. A static load of 1.2 x 150 kN = 180 kN was applied before the fatigue test. After the fatigue test the static load was increased to 2 x 150 kN = 300 kN. No damage to the sleeper could be established during the fatigue test. The ribbed plate was subsequently removed. Plastic deformations of approximately 0.85 mm. Extraction tests on FFU height 120 mm The tests were conducted in line with EN 13481-2 attachment A on 12 sleeper screws Ss 8-140 and synthetic wood sleepers with a height of 120 mm. TU Munich September 2013 Sleeper screw Ss-8 – diameter 24 mm Hole diameter / drill tool Mean value [kN] 19 mm / steel drill 56.8 20 mm / steel drill 52.7 20 mm / wood drill 49.6 Slim tie with a height of 100 and 120 mm
    • Static tests in centre of sleeper (sleeper heights 100 mm and 120 mm) The support spacing was 1.5 m and load plate width was 100 mm. The initial test load was set to 10 kN. Subsequently the load was increased in increments of 10 kN, with sleeper bending registered on four dial gauges. Diagram below shows the values of sleeper bending up to a load of 70 kN, corresponding to a torque of 24.5 kNm TU Munich September 2013 Slim tie with a height of 100 and 120 mm
