When the vehicles run away on a road, a certain point of the pavement comes under influence of dynamic load at a moment. In order to clear the characteristics of asphaltic pavement under repeated impulsive load, writers have performed an experiment as following. Firstly the specimens for Marshall test have been made of coarse-graded, dense-graded asphalt concrete and topeca with or without powdered rubber. And then a test head setting this specimen has been placed into 60℃ water bath as shown in Fig. 1. The whole apparatus has been set under a mechanical compactor for the preparation of CBR test specimen. The rammer of 4.5kg weight has been automatically dropped on the test head covered by a rubber cushion from 45cm height. After a certain number of repeated dropping, measurement of deformation by means of flow meter and Marshall test have been performed for each specimen. The results obtained in these experiments are mentioned and investigated here.
