REPEATED LOADING TESTER FOR USE ON PAVEMENTS /IN PORTUGUESE/

THE AUTOMATIC EQUIPMENT DESCRIBED IS USED IN FULL- SCALE TESTS ON ACCELERATED FAILURE OF PAVEMENTS. THIS EQUIPMENT FACILITATES THE APPLICATION OF LOADS EQUAL TO THE HEAVIEST SINGLE-AXLE WHEEL LOAD OF THE VEHICLE USUAL IN THIS COUNTRY. THE SPEED OF THIS APPLICATION IS EQUAL TO THAT OF THE WHEEL PASSING AT 66 KM/H, AND ITS RHYTHM IS SUCH THAT THE NUMBER OF APPLICATIONS IN ONE HOUR WILL BE SOMEWHAT GREATER THAN THE MEAN DAILY, HEAVY-TRAFFIC VOLUME IN THIS COUNTRY. WITH THE HELP OF THIS EQUIPMENT USED ON LNEC SOIL TRIAL-PIT, IT IS NOW POSSIBLE TO STUDY THE BEHAVIOR OF FOUNDATION SOILS, PAVEMENTS, AND STRENGTHENING LAYERS, TO TRY TO CORRELATE THEM WITH THE CHARACTERISTICS OF THE MATERIALS FORMING THE DIFFERENT COURSES. /TRRL/
