PERFORMANCE OF A REINFORCED EARTH BRIDGE ABUTMENT AT CARMARTHEN

Four bridge abutments were constructed over the alluvial floodplain of the Afon Tywi near Carmarthen using the Websol reinforced earth system. This system incorporated polyester reinforcing straps (paraweb) and sheets of melt-bonded geotextile (terram). The construction and instrumentation of one of the abutments is described and an assessment of the structure during construction and up to the end of its third year in service is also given. Measurements taken in the three years after the opening of the bypass to traffic in 1983 indicate that no significant changes have occurred to the reinforced earth structure during this period.
