<br />11.GEOTECHNICAL RECOMMENDATIONS:
<br />A. EXCAVATIONS, SUBGRADE PREPARATION, ROCK FILLING, AND SOIL
<br />COMPACTION SHOULD BE OBSERVED BY A REPRESENTATIVE OF
<br />TERRACON. ACTUAL QUANTITIES FOR EARTHWORK WILL DEPEND ON
<br />CONDITIONS ENCOUNTERED IN THE FIELD DURING CONSTRUCTION.
<br />B. ROCK SLOPE PROTECTION (ROCK) TO BE PLACED DIRECTLY INTO
<br />AREAS WITH RELATIVELY DEEP AND NARROW GULLIES. EXCAVATE
<br />LOOSE OR UNSTABLE SOIL AS EVALUATED BY TERRACON.
<br />C. COMPACTED SOIL SHOULD BE PLACED OVER ROCK FOR FINISH
<br />GRADING IN AREAS TO RECEIVE IMPROVEMENTS (I.E., CONCRETE
<br />V-DITCH OR PAVEMENT) OR WHERE IT IS DESIRED TO ESTABLISH
<br />FINISH GRADES WITH SOIL INSTEAD OF ROCK. FABRIC SHOULD BE
<br />PLACED AT THE BOTTOMS AND SIDES OF THE ERODED AREAS TO
<br />RECEIVE ROCK AND ON TOP OF ROCK WHERE COMPACTED SOIL IS
<br />USED TO ESTABLISH FINISH GRADES.
<br />D. ROCK TO CONFORM TO FACING CLASS ROCK SLOPE PROTECTION IN
<br />CONFORMANCE WITH CALTRANS STANDARD SPECIFICATIONS
<br />SECTION 72-2. THE STANDARD SPECIFIES THE USE OF ANGULAR
<br />ROCK, METHOD B FOR PLACEMENT, AND RSP FABRIC CLASS NO. 8.
<br />SOIL TO BE COMPACTED SHOULD BE PLACED IN HORIZONTAL LIFTS
<br />NOT EXCEEDING 8 INCHES IN LOOSE THICKNESS AND COMPACTED
<br />TO AT LEAST 90 PERCENT RELATIVE COMPACTION AT 2 PERCENTAGE
<br />POINTS ABOVE OPTIMUM MOISTURE CONTENT AS DETERMINED BY
<br />ASTM D1557.
<br />E. AT THE BRIDGE LOCATION, A LEVEL KEYWAY OR TRENCH ABOUT 4
<br />FEET WIDE SHOULD BE EXCAVATED INTO FIRM MATERIAL. LOOSE OR
<br />UNSTABLE SOIL AND DELETERIOUS MATERIAL WITHIN THE ERODED
<br />AREAS SHOULD BE EXCAVATED TO EXPOSE FIRM AND STABLE
<br />MATERIAL PRIOR TO ROCK PLACEMENT AS EVALUATED IN THE FIELD.
<br />EXCAVATION TO CREATE RELATIVELY LEVEL BENCHES ON THE
<br />SLOPE MAY BE NEEDED FOR ROCK PLACEMENT. IT MAY BE POSSIBLE
<br />TO PLACE THE ROCK NEAR ITS PLANNED LOCATION USING
<br />EQUIPMENT FROM THE EXISTING BRIDGE DECK WITH THE ROCK
<br />THEN WORKED INTO ITS FINAL POSITION USING EQUIPMENT ON THE
<br />SLOPE.
<br />F. RELATIVELY SMALL VOIDS ADJACENT TO THE BRIDGE ABUTMENT
<br />AND FOOTINGS EXTENDING UNDERNEATH THE STRUCTURAL
<br />CONCRETE, WHICH CANNOT BE BACKFILLED WITH ROCK SLOPE
<br />PROTECTION (RSP), SHOULD BE BACKFILLED WITH COMPACTED
<br />LOW-STRENGTH MATERIAL (CLSM). EXCAVATION OF LOOSE OR
<br />UNSTABLE SOIL MAY BE NEEDED IN SOME OF THESE AREAS PRIOR
<br />TO CLSM PLACEMENT. THE CLSM SHOULD HAVE A 28-DAY
<br />COMPRESSIVE STRENGTH FROM 50 TO 100 PSI AND SHOULD BE A
<br />FLUID WORKABLE MIXTURE OF AGGREGATE, CEMENT, AND WATER IN
<br />ACCORDANCE WITH CALTRANS STANDARD SPECIFICATIONS SECTION
<br />19-3.02G. FORMS AND OTHER CONTROL SHOULD BE ESTABLISHED TO
<br />CONTAIN THE CLSM AND PREVENT IT FROM FLOWING DOWNSLOPE
<br />INTO THE CHANNEL. BACKFILLING OVER THESE AREAS SHOULD BE
<br />PERFORMED AFTER THE DESIGN COMPRESSIVE STRENGTH OF THE
<br />CLSM HAS BEEN CONFIRMED.
<br />G. AT THE BRIDGE LOCATION, THE INTENT IS TO AVOID DISTURBANCE
<br />AND WORK WITHIN THE DRAINAGE CHANNEL BOTTOM. WHERE
<br />LIMITED WORK IS REQUIRED WITHIN THE CHANNEL NEAR THE
<br />BRIDGE, SMALL EARTHWORK EQUIPMENT LOWERED INTO THE
<br />CHANNEL USING A CRANE SHOULD BE ANTICIPATED. NO TEMPORARY
<br />RAMPS OR ROADS INTO THE DRAINAGE CHANNEL WILL BE ALLOWED.
