1 PROJECT THE PROJECT CONSISTS OF CONSTRUCTING TWIN STRUCTURES FOR PROPOSED SR OVER SLOCUM AVENUE (TR-). THE TWO STRUCTURES ARE THREE-SPAN STRUCTURES USING SPI-THROUGH SLOPES AT THE ABUTMENTS. AN MSE WA IS ALSO PROPOSED TO RETAIN THE EMBANKMENT ON THE EAST SIDE OF THE BRIDGE BETWEEN PIER AND THE FORWARD ABUTMENT. HISTORIC RECORDS HISTORIC BORING RECORDS FOR THE AREA WERE REQUESTED FROM THE ODOT OFFICE OF GEOTECHNICAL ENGINEERING AND THE DISTRICT, HOWEVER, NO SUCH RECORDS EXISTED. GEOLOGY BEDROCK IS OF THE MISSISSIPPIAN LOGAN FORMATION. GENERAY, THIS FORMATION CONSISTS OF PRIMARILY SANDSTONE OR SANDY SILTSTONE WITH OCCASIONAL AREAS OF INTERBEDDED SHALE. HOWEVER, THE LITHOLOGY OF THE SANDSTONES VARIES BOTH LATERAY AND VERTICAY. WITHIN THIS AREA THE LOGAN FORMATION TYPICAY CONSISTS OF THICK, MASSIVE SANDSTONE UNITS. LEGEND GRAVEL AND/OR STONE FRAGS.

HUNTLEY ROAD * COLUMBUS, OHIO RECONNAISSANCE SEVERAL SITE RECONNAISSANCE VISITS WERE MADE BETWEEN AUGUST AND SEPTEMBER. THE SURROUNDING AREA IS DESCRIBED AS RURAL RESIDENTIAL. THE PROJECT AREA IS LOCATED IN THE LITTLE SCIOTO RIVER VAEY AND AND IS BOUNDED ON EITHER END BY STEEP SLOPES. THE STEEP SLOPES ARE COVERED WITH TREES AND BRUSH WHILE THE RELATIVELY LEVEL VAEY BOTTOM IS A RESIDENTIAL AREA.

BORINGS TR- THROUGH TR- WERE DRIED BETWEEN JANUARY AND FEBRUARY, FOR THE PRELIMINARY BRIDGE CONFIGURATION. BORINGS B- AND B- WERE DRIED BETWEEN JANUARY AND,, FOR THE CURRENTLY PROPOSED STRUCTURE. TWO ADDITIONAL BORINGS, TR-A AND TR-A, WHICH WERE DRIED FOR THE FORWARD ABUTMENT EMBANKMENT AND THE REAR ABUTMENT EMBANKMENT, RESPECTIVELY, WERE ALSO CONSIDERED IN THE ANALYSES. BORING TR-A WAS DRIED ON JANUARY, AND BORING TR-A ON JANUARY AND, WITH AN ATV MOUNTED ROTARY DRI RIG, USING / -INCH I.D. HOOW STEM AUGERS TO ADVANCE THE HOLES THROUGH SOIL. DISTURBED SOIL SAMES WERE OBTAINED IN ACCORDANCE WITH THE STANDARD PENETRATION TEST (AASHTO T) AT. TO.-FOOT INTERVALS FOR THE FU DEPTH OF THE SOIL PORTION OF THE BORINGS. UNDISTURBED SOIL SAMES WERE OBTAINED AT THE DEPTHS SHOWN ON THE LOGS AND IN THE PROFILE, IN ACCORDANCE WITH AASHTO T. WHERE BEDROCK WAS ENCOUNTERED, THE BORINGS WERE ADVANCED AND THE ROCK WAS SAMED USING A TYPE NQ SERIES CORE BARREL, METHOD. EXORATION FINDINGS THE TEST BORINGS DISCLOSED PRDOMINANTLY COHESIVE DEPOSITS THAT CONSISTED OF MAINLY STIFF TO HARD SILT AND CLAY (A-A), SOFT TO MEDIUM STIFF SANDY SILT (A-A), MEDIUM STIFF TO HARD SILT (A-B), STIFF TO HARD SILTY CLAY (A-B), AND STIFF TO HARD CLAY (A--), WHILE THE GRANULAR SOILS ENCOUNTERED CONSISTED OF MAINLY OF VERY LOOSE TO MEDIUM DENSE SANDY SILT (A-A), VERY LOOSE TO MEDIUM DENSE SILT (A-B) AND LOOSE TO MEDIUM DENSE COARSE AND FINE SAND (A-A). THE NATIVE SOILS EXTENDED TO DEPTHS RANGING BETWEEN AND FEET BELOW THE GROUND SURFACE, WHERE BEDROCK WAS ENCOUNTERED. BEDROCK ENCOUNTERED IN THE BORINGS WAS MOSTLY SANDSTONE EXCEPT IN BORING B- WHERE SILTSTONE WAS ENCOUNTERED WITHIN THE DEPTH OF BORING. THE BEDROCK ENCOUNTERED WAS MOSTLY MEDIUM HARD TO HARD, MODERATELY WEATHERED, AND SLIGHTLY TO MODERATELY FRACTURED. HOWEVER, A LAYER OF SEVERELY WEATHERED ROCK, APPROXIMATELY FEET THICK, WAS ENCOUNTERED ABOVE THE MORE COMPETENT, CORED BEDROCK IN BORINGS TR- AND TR-. THE AMOUNT OF ROCK RECOVERED IN EACH CORE RUN MOSTLY VARIED FROM TO PERCENT AND THE ROCK QUALITY DESIGNATION () OF THE BEDROCK GENERAY RANGED FROM TO PERCENT WITH AN AVERAGE OF PERCENT, INDICATING GOOD QUALITY ROCK. RELATIVELY SEVERE LOSS OF RECOVERY OCCURRED IN THE CORE RUNS BETWEEN DEPTHS OF AND FEET IN BORING TR-. RECOVERY OF THE CORE SAME WAS ONLY PERCENT AND THE VALUE WAS PERCENT BETWEEN THE DEPTHS OF AND FEET OF THIS BORING. HOWEVER, THE CORE SAME WAS UNABLE TO BE RECOVERED BETWEEN THE DEPTHS OF AND FEET. SEEPAGE WAS FIRST ENCOUNTERED IN THE BORINGS AT DEPTHS RANGING FROM. TO. FEET BELOW THE GROUND SURFACE. A MEASURABLE LEVEL WAS ENCOUNTERED IN BORINGS B-, B-, TR- AND TR-A, PRIOR TO ROCK CORING, AT DEPTHS RANGING FROM. TO. FEET BELOW THE GROUND SURFACE. WAS USED DURING ROCK CORING AND MASKED ANY SEEPAGE ZONES THAT MIGHT EXIST IN THE ROCK.
