what is wtt testing
Abstract. 1  The wheel tracking test (WTT) is an important tool to define asphalt mixture rutting performance. In this study, the rutting behaviour in the WTT was compared under two different standards, BS 598-110 and EN 12697-22 small size device procedures.
The glucose tolerance test, also called an oral glucose tolerance test (OGTT) is used to diagnose diabetes in pregnancy (gestational diabetes). Up to 14 per cent of pregnant women develop gestational diabetes (Tieu et al 2008). The test checks how your body regulates your sugar levels. Sugar, or glucose, is found in many of the foods you eat.
