Notes:

1) Concrete shall attain 4,000 p.s.i. compressionstrength in 28 days.

2) Contraction joints shall be constructed at allpoints of curvature and at a maximum intervals of20 feet.

3) This curb design is limited to use in cul-de-sac orother special circumstances specifically approved bythe City Engineer.

Notes:1) Concrete thrust blocking to be poured against undisturbed earth. 2) Keep concrete clear of jointand accessories. 3) If not shown on plans, required bearing areas at fitting shall be as indicatedbelow, adjusted if necessary, to conform to the test procedure (S) and allowable soil bearing stress(ES) stated the special specifications. 4) Bearing areas and special blocking details shown on planstake precedence over bearing areas and blocking details shown on this standard detail. 5) Buildingpaper or visquine shall be placed between concrete and fittings. 6) All poured in place concrete shallhave a (28) day strength of 3,000 p.s.i. and 2" to 4" slump. 7) Below bearing areas based on testprocedure of 150 p.s.i. and an allowable soil bearing stress of 2,000 pounds per square foot. Tocompute bearing areas for different test pressures and soil bearing stresses, use the followingequation: bearing area = (test pressure/150) X (2,000/soil bearing stress) X (table value). Bearingareas in square feet.
