At the annual meeting of the Society for Bituminous Works VBW in 1972 three papers were read: (1) Technical-Economical Aspects of Highway Reconstruction, Span, HJT. After having recalled the essential functions of the road and the aspects of highway design and pavement properties which are most important for the performance of these functions, Prof. Span reviews in brief the measuring and calculation methods generally used for planning, strengthening or reconstruction operations. An example is given of strain calculation for a bituminous pavement layer. (2) Vegetation Problems Caused By Highway Reconstruction, Guldemond, JL. The harmful consequences for roadside trees of carriageway widening or replacement of brick paving by an impermeable surfacing are discussed, especially the need for oxygen and moisture access to the root system of trees. (3) Traffic Regulation Measures To Be Taken During Construction Activities On Motorways, Westerduin, B. Temporary signs and signals to be used at bottle-necks caused by construction or maintenance operations are discussed. An example is given of the calculation of traffic delay caused by the closure of one lane of a carriageway. /TRRL/
