• Humidity and temperature bath 50°F (10°C), 90 percent relative humidity; 104°F (40°C), 90 percent relative humidity). Figure 3.8 shows a simple conditioning system for humidity/night-time curing of samples that has been used in an actual field project. The space at the bottom may contain water with ice for low temperature-high humidity, or hot water for higher humidity. A cooler or heater and a thermostat control the water temperature. 3.6.5 The Loaded Wheel Test (LWT) The LWT may be used to establish the upper limit of bitumen content by determining the amount of sand adhesion in accordance with TB-109. Determining the upper bitumen limit is important to prevent bleeding of mixes in service and this test should be modified to include different conditions. The test will be used as is, but conditioning of samples will be carried out at 59°F (15°C), 77°F (25°C), and 95°F (35°C) to allow for the effects of high shear or high temperature. Deformation in early life is evaluated using cohesion testing. Figure 3.7: CAT Test 23
Samples Holes 0.8 inches (~0.20 mm Diameter) Air Gap 4-6 inches (100-150 mm) Figure 3.8: Proposed Curing/Conditioning System 3.6.6 Long Term Performance Tests Air Gap 0.75 – 1.25 inches (20 -30 mm) Water / Ice 0.75 – 1.25 inches (20 -30 mm) The long-term properties of S3 mixes are dependent on their mechanical properties and their ability to maintain these properties over time and under service conditions. This makes them no different from any other thin aggregate/binder mixtures such as thin and ultra-thin hot mix overlays. For high traffic or rut filling applications, when the material is placed in thicker layers up to 4 inches (100 mm), performance becomes important and must be evaluated in the design process. Table 3.6 provides a list of candidate tests that were identified in the original proposal. 24 Thermometer Sieve or Tray
