PROGRESS ON THE NURSERY SLOPES
Vegetation has been shown to reduce shallow slope failures on embankments and cuttings. A research project conducted in the UK by the Highways Agency and TRL on slope stability and the establishment of vegetation is described. The first phase identified a selection of plant species to be used in controlled trials to determine their growth in over-consolidated clay soils. A trial embankment, built at TRL, was planted with 20 species of trees, shrubs and perennials. A low survival rate was observed when live willow poles were installed at a site on the A249 at Iwade. A survey of vegetated reinforced slopes showed variable success. The primary causes of failure were lack of water and southerly facing slopes. Following a review by TRL, three trial sites were established on the M1 at Toddington, the A5 at Milton Keynes and the A10 at Hoddesdon. The results will provide information on long-term plant growth. For the covering abstract see ITRD E116081.
