MECHANICAL PROPERTIES OF BASE COURSE MATERIALS

A Pavement Test Facility has been developed at the Road and Transport Laboratory of the University of Oulu, Finland in order to overcome the above difficulties. The pavement structure to be tested is produced in a testbox of size 1200 x 900 x 600 mm and unidirectional or bidirectional loads in the range 7 to 25 kN can be imposed using a moving wheel. The load speed is 5 km/h. The facility is constructed inside an environmental chamber, the temperature of which can be adjusted within the range +5 ...+60 degrees C. Elastic and permanent deflections are measured by LVDTs connected to thin steel rods placed at any point required within the test structure. Elastic and permanent strains in the various layers can be determined from these deflections.
