MODEL AND FIELD TESTS OF REINFORCED PAVEMENT OF SOFT CLAY GROUND ---PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON THEORY AND PRACTICE OF EARTH REINFORCEMENT, FUKUOKA, KYUSHU, JAPAN, 5-7 OCTOBER 1988

Tests were conducted to investigate the ability of polymer grids to suppress non uniform settlement of asphalt pavement on soft ground (ariake clay). Model pavements were constructed in a concrete soil tank using reconstructed ariake clay as subgrade. A 5 cm asphalt layer was laid on top of the compacted subbase and base course. Both a one and a two layered polymer grid system was used. Repeated loads of 2 kg per square metre with a frequency of 0.18 hz were applied, and the modulus of subgrade reaction calculated. An analysis of the reinforced soil structure, which introduced the joint element, was effected by the finite element method. Field tests were also carried out using six 50 m sections of different types of road. Each section was constructed using ariake clay subsoil covered by 60-80 cm coal mine waste. The remaining pavement layers of two sections were constructed by conventional methods and four were constructed using two different types of polymer grid (ss3 and ss2). Bearing capacity was measured by 30 cm diameter plate load tests. Benkelman beam tests were also carried out and the vertical stresses were measured. The reinforcing effect of the polymer grid was discussed. For the covering abstract of the symposium see IRRD 818063.
