...% improvement in the average level of skid resistance could result in a 13% reduction in the wet-skid accident rate. The same rate is also estimated to be valid for Greece. Other studies indicate that microtexture appears to be the most important pavement parameter in determining accident rates. Macrotexture...

... that a 10% price increase in petrol tax would lead to a 7% reduction in vehicle use, and would affect manufacturing as well as individual behaviour patterns. However, support for the motion does not imply increasing the burden of tax on motoring; it must be considered in the context of switching from fixed...

Piles cannot bereadily inspected once they have been constructed, and variations in the bearing stratum aredifficult...
