WebThe study aims to identify aspects of school inspections (e.g. standards and thresholds, sanctions and rewards) that maximise the positive, intended effects of school inspection and minimise the negative, unintended effects (Ehren et al. 2013). This paper focuses on the survey items aimed at measuring the side effects of school inspection.
The permeability values obtained in terms of coefficient of permeability of GSB mixes are less than 3.17 m/d indicating that these mixes cannot be used for subsurface drainage purpose. On the contrary, the use of such layer may serve as a structural layer that is a lower sub base but without desired drainage property.
