A case study of reinforced pavement above trench under urban traffic load
View through CrossRef
Every year, trenches are being excavated through an existing pavement in Iran for installing urban waste water pipelines. The pavements constructed over these trenches undergo large permanent settlement as many times these trenches are not filled back properly. To reduce the settlements, geogrids have been used at the top of the base course. This case study presents the observed settlements of unreinforced and geogrid reinforced pavement, under urban traffic load, monitored over a period of twelve months. It was observed that the geogrids were highly effective in reducing the settlements in the pavement. The results obtained also show that the geogrids improve the stiffness and strength of the pavement and control the rut formation.
