SOIL VIBRATION STUDY

IT HAS BEEN OBSERVED BY HIGHWAY ENGINEERS THAT CRACKS AND BUMPS FORM IN PAVEMENT ADJACENT TO HIGHWAY BRIDGES AND BOX CULVERTS. WHEN A CRACK FORMS, THE DAMAGE IS AGGRAVATED BY HIGHWAY TRAFFIC AND WEATHER TO A POINT WHERE THE PAVEMENT MUST BE REPAIRED. THE SCOPE OF THIS RESEARCH PROGRAM WAS TO DEVISE A METHOD OF EVALUATING PROBABLE BEHAVIOR OF SOILS ADJACENT TO BRIDGE ABUTMENTS. IN THIS INVESTIGATION DIFFERENT SOIL BLENDS HAVE BEEN SUBJECTED TO BOTH IMPACT AND VIBRATION TESTS. RESULTS FROM THESE TESTS SHOW SIMILAR TRENDS IN THE BEHAVIOR OF SOILS UNDER DYNAMIC LOADING. IT IS , THEREFORE, ASSUMED THAT THE RESULTS OF THESE TESTS CAN BE EXTENDED TO APPLY TO THE DESIGN AND CONSTRUCTION OF HIGHWAY SUBGRADES AND FILLS ADJACENT TO ABUTMENTS. THE MAGNITUDE OF THE VIBRATION AND IMPACT INDICES, DETERMINED FROM THESE TESTS, INDICATES THE SUSCEPTIBILITY OF THE SOILS TO VOLUME CHANGE UNDER DYNAMIC LOADS. /AUTHOR/
