BEARING CAPACITY OF AIRFIELD PAVEMENTS: PLATE BEARING AND FALLING WEIGHT DEFLECTOMETER TESTS COMPARED

The bearing capacity of airfield pavements in Canada, since the second world war, has been estimated on the basis of static plate load tests. Such tests are time consuming and have become increasingly expensive. In addition, the test equipment is cumbersome and cannot be quickly removed from a runway. The development of heavy falling weight deflectometers capable of applying loads more representative of aircraft wheel loads has renewed interest in substituting falling weight tests for the traditional plate bearing tests. In order to pursue this, a program of parallel testing was carried out in which both falling weight and plate bearing tests were carried out on the same pavements at several Canadian airfields. These tests and the comparison of data from them and from parallel controlled rate of loading tests are the subject of this paper.
