<br />DESIGN A A S H 0 DATED 1973 WITH REVISIONS AND AS SUPPLEMENTED
<br />BY BRIDGE PLANNING ANDDESIGN MANUAL.
<br />SECTIONS DESIGNED FOR CULVERT W A TRENCH ON HARD
<br />FOUNOATION,OR CULVERT UNTRENCHED ON YIELDING
<br />FOUNDATION FOR CULVERTS ON PILES OR ROCK
<br />FOUNDATIONS, SPECIAL DESIGN WILL BE REQUIRED
<br />LOADING
<br />LIVE LOAD FOR LEGAL HIGHWAY LOADS, USE HS20-44 OR ALTERNATIVE,
<br />WITH 30% IMPACT FOR ALL COVER DEPTHS NO IMPACT ON INVERT
<br />COVER LESS THAN 2'- WHEEL LOAD DISTRIBUTION ON THE TOP SLAB IS
<br />E.n0.175S+3.2' LONGITUDINALLY AND CONCENTRATED
<br />ALONG THE SPAN WHEEL LOAD DISTRIBUTION
<br />ON THE INVERT SLAB IS 7.5' LONGITUDINALLY AND
<br />UNIFORMLY OVER THE BREATH OF THE CULVERT
<br />COVER 2' OR MORE - WHEEL LOADS DISTRIBUTED UNIFORMLY OVER A
<br />SQUARE,THE SIDES OF WHICH ARE 175 TIMES THE
<br />DEPTH OF COVER, BUT NOT LESS LONGITUDINALLY THAN E
<br />ON THE TOP SLAB,OR 75'ON THE INVERT SLAB
<br />WHEN SUCH AREAS FROM SEVERAL WHEEL
<br />CONCENTRATIONS OVERLAP, THE TOTAL LOAD SHALL
<br />BE CONSIDERED AS UNIFORMLY DISTRIBUTED OVER THE
<br />AREA DEFINED BY THE OUTSIDE LIMITS OF THE
<br />INDIVIDUAL AREAS, BUT THE OVERALL LONGITUDINAL
<br />DIMENSION SHALL NOT EXCEED THE TOTAL LENGTH
<br />OF THE SUPPORTING SLAB. NEGLECT LIVE LOAD,ON SINGLE
<br />SPANS WHEN COVER IS MORE THAN 8' AND EXCEEDS
<br />SPAN, ANDON MULTIPLE SPANS WHEN COVER EXCEEDS
<br />DISTANCE BETWEEN EXTERIOR WALLS.
<br />DEAD LOAD EARTH LOAD OF 120 PCF AND AN EQUIVALENT FLUID PRESSURE OF
<br />36 PCF,REDUCED TO 84 PCF AND 25 PCF RESPECTIVELY FOR
<br />CLEAR SPANS OF 20'OR LESS.

<br />CONSTRUCTION NOTES
<br />GENERAL NOTES
<br />QUANTITIES : QUANTITIES ARE FOR THE SLOPED INVERT SLAB AND DO NOT
<br />INCLUDE SPLICES IN LONGITUDINAL BARS, NOR TEMPERATURE
<br />REINFORCEMENT FOR EXPOSED TOP CULVERT, NOR CONCRETE
<br />OR REINFORCEMENT FOR PARAPETS OR CUTOFF WALLS
<br />SPECIAL COVERAGE BOX STANDARD PLANS ARE NOT TO BE USED FOR CULVERTS
<br />IN A CORROSIVE ENVIRONMENT OR WHERE THERE IS A SEVERE
<br />ABRASIVE FLOW CONDITION.
<br />DESIGNATION : SHOW ON PLANS AS SPAN X HEIGHT - STRENGTH CLASSIFICATION
<br />X LENGTH THUS 4 x 4 -A x 60' , FOLLOWED BY ALTERNATIVES
<br />ALTERNATIVES: INVERT WILL BE SLOPED UNLESS "TRAPEZOIDAL INVERT ", " FLAT
<br />INVERT" OR "V INVERT" IS INCLUDED IN DESIGNATION. ENOS OF
<br />CULVERT WILL BE ROUNDED UNLESS "SQUARE ENDS" ARE DESIGNATED
<br />PARAPETS WILL BE AS SHOWN UNLESS .— FT. PARAPET" IS
<br />DESIGNATED IN PLANS. SUCH DESIGNATIONS MAY BE DIFFERENT
<br />FOR INLET AND OUTLET ENDS.
