5.0 CHAPTER 5 RUGGEDNESS TESTING 5.1 PURPOSE OF THE EXPERIMENTS The overall purpose of a Ruggedness Testing Experiment is to evaluate the sensitivity of the output of a particular test to allowable variation in the test conditions. (13) For example, consider a simple hypothetical test method involving a device that can be used to measure the sodium content in a given sample of water. Under the range of typical test conditions, the result of this test may be sensitive to the variability of such factors as the temperature of the water, the amount of solar radiation, and the level of other chemicals and contaminants in the water. A ruggedness test for this device (test method) would involve the design and conduct of an experiment to determine the overall effect of the variation of these other factors on the primary test result (i.e., the sodium content of the water). If the test result is unaffected by the variation of the other factors (within their typical ranges), then the test method is considered rugged. Obviously, ruggedness is a desirable attribute for all test methods, including those that will be used for slurry/micro-surfacing mix design. For any given test method associated with the mix design process, the evaluation of ruggedness can best be done by performing all of the tests in one laboratory, so that there is no laboratory effect to consider. The results from the ruggedness experiment will then provide a basis for evaluating the effect of test conditions under later round-robin testing of the test methods. 5.2 STATISTICAL MODEL For each of the test devices/methods undergoing the ruggedness testing, the statistical model that will be used to evaluate the effect of the variability of test conditions will be a simple linear model. This means that each of the condition variables (X1, X2, X3, and so on) will be evaluated as if they have a linear effect on the dependent variable (i.e., the value of the test result). Considering the overall purpose of the analysis, it is reasonable to assume that the sensitivity can be characterized and evaluated using first order (linear) effects (see Figure 5.1a). Although the relationship may have some curvilinearity, the linear model does capture the primary effect in the region between the low and high levels of the condition variable. The one case where this assumption can break down is the situation where the condition variable has a quadratic effect and the low and high levels of the condition variable are set at points where they have a near-equal effect on the test result (see Figure 5.1b). In this case, the model would indicate a near zero effect, when the effect is actually significant. Considering the 78
