STUDIES INTO THE CONSTRUCTION OF LOW TRAFFICKED ROADS IN THE CITY OF SALISBURY, SOUTH AUSTRALIA
Two separate investigations are covered in this report. In Part I, Benkelman Beam measurements were carried out on low trafficked urban streets in the City of Salisbury, South Australia, to assess the structural strengths of different types of pavement construction. The pavements had been constructed, in three zones of different subgrade strength, either by stages or initially to full depth. The materials used in the pavements were either crushed rock or macadam and in some instances stabilisation with lime, cement or bitumen had been used. In some streets the subgrade, an essentially clayey material, had been stabilised with lime or cement. Recommendations are given as to thicknesses and types of construction in the three zones. In Part II, two methods of assessing subgrade (CBR) strength--one a field and one a laboratory method--were compared with the standard in-situ CBR method.
