CAUSE AND PREVENTION OF DAMAGE TO ROADS DUE TO MOISTURE EXTRACTION BY TREES

OORZAAK EN PREVENTIE VAN SCHADE AAN WEGEN DOOR VOCHTONTTREKKING DOOR BOMEN

In dry years rural roads near tree plantings show cracks and settlements. This is caused by the shrinking of the peat and clay subsoil due to moisture extraction by trees in the road verges. This report describes the process of shrinking and ripening and presents calculation methods for assessing the settlement. At five locations in the Netherlands comprehensive altimetries were carried out, and the course of ditch levels and groundwater levels was monitored. At three measurement sites in the Netherlands a profile hole was dug straight through the road. It appears that soil type, groundwater level, presence of deep water-bearing ditches, and the permeability of the soil have a great impact on the chance of damage. Choosing the right type of tree can prevent or limit a lot of damage.
