Abstract
The paper describes an innovative method for stabilisation and greening of newly formed road slopes. Meandrically arranged thick ropes made from textile waste covered with soil mixed with randomly distributed wool and polyester fibres were applied for stabilisation. The ropes were installed on the slope in autumn. Hydroseeding was performed the following spring. Behaviour of the slope during several months was regularly monitored. In the first period – during autumn and winter – the ropes in combination with fibre-reinforced soil reduced the danger of local landslides and soil erosion. After hydroseeding the system provided water supply needed for seed germination. During grass growth the fertilising effect of nitrogen compounds released as a result of wool biodegradation was revealed. Finally, a stable slope covered with high grass grown in a relatively short time was achieved.
期刊介绍：
The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
