TERRAIN INVESTIGATION TECHNIQUES FOR HIGHWAY ENGINEERS

THE OBJECTS ARE (A) TO INVESTIGATE THE MOST ECONOMICAL AND RELIABLE COMBINATIONS OF DIRECT AND INDIRECT SOIL EXPLORATION TECHNIQUES FOR PROCURING REPRESENTATIVE SOIL AND BEDROCK INFORMATION FOR HIGHWAY DESIGN, AND (B) TO USE THE DATA FROM THE INVESTIGATION TO DEVELOP A MANUAL ON TERRAIN INVESTIGATION TECHNIQUES. AERIAL PHOTOGRAPHY AND GEOPHYSICAL TECHNIQUES ADAPTABLE FOR SHALLOW SUBSURFACE INVESTIGATIONS WERE EVALUATED, AND COMBINATIONS OF AIRPHOTO INTERPRETATION, GEOPHYSICAL SURVEY AND DIRECT SOIL INVESTIGATION METHODS DETERMINED FOR ACCURATE AND REPRESENTATIVE SOIL PROFILES FOR HIGHWAY DESIGN USE. THE RECOMMENDATIONS MADE INCLUDE THE FOLLOWING: PROCURE SOIL AND ROCK DATA FROM INVESTIGATIONS OF (1) UPLAND TERRAIN OF RESIDUAL SOILS BY A COMBINATION OF PHOTOINTERPRETATION, SEISMIC REFRACTION, ELECTRICAL RESISTIVITY AND CORE-BORING TECHNIQUES; (2) THICK LAYERS OF GLACIATED TERRAIN BY A COMBINATION OF PHOTOINTERPRETATION, ELECTRICAL RESISTIVITY AND POWER-ANGER SAMPLING TECHNIQUES; (3) THIN LAYERS OF GLACIATED TERRAIN BY A COMBINATION OF PHOTOINTERPRETATION, ELECTRICAL RESISTIVITY AND SEISMIC REFRACTION OF SURVEYS, POWER-AUGER AND/OR CORE-BORING SAMPLING TECHNIQUES; (4) LANDSLIDE SUSCEPTIBLE TERRAIN BY PHOTOINTERPRETATION, ELECTRICAL RESISTIVITY AND CORE-BORING TECHNIQUES AND, (5) SOFT SUBSOIL TERRAIN BY PHOTOINTERPRETATION, ELECTRICAL RESISTIVITY AND PRESS- SAMPLING TECHNIQUES.
