G. Flow fill shall be protected from freezing until it has hardened.

H. Flow fill mixing and placement may be started if weather conditions are favorable, when the air

temperature in the shade and away from artificial heat is at least 34 degrees Fahrenheit and

rising. Mixing and placing shall stop when the air temperature in the shade and away from

artificial heat is 38 degrees Fahrenheit or less and falling, and in no care shall flow fill be placed

with the air temperature is lower than 34 degrees Fahrenheit.

I. It shall be the Contractor’s responsibility to ensure that the backfilled trench is not exposed to

vehicular traffic loads until such time that the fill material has sufficiently cured to support the

anticipated vehicle loads. Prior to reopening the roadway to normal traffic, the Contractor shall

subject the fill material to a vehicular test load that is reasonably representative of the ultimate

loading anticipated. When the fill material supports such vehicular test load without apparent

deformation, said fill material shall be deemed sufficiently cured to permit reopening of the

roadway to normal traffic.


A. Testing Agency: Owner will engage a qualified independent geotechnical engineering testing

agency to perform field quality-control testing.

B. Allow testing agency to inspect and test subgrades and each fill or backfill layer. Proceed with

subsequent earthwork only after test results for previously completed work comply with

requirements.

C. Testing agency will test compaction of soils in place according to ASTM D 1556, ASTM D 2167,

ASTM D 2922, and ASTM D 2937, as applicable. Perform field moisture tests in accordance with

ASTM D3017. Tests will be performed at the following locations and frequencies at a minimum:

1. Trench Backfill: The density tests shall be performed during backfilling at specified depths

in the trench to ensure that the required density and moisture is obtained throughout.

For trenches less than 30-inches in depth, density tests shall be taken within 18-inches

above the top of pipe or conduit and at the surface/toplift as a minimum. For trenches

greater than 30-inches in depth, density tests shall be taken within 18-inches of the top

of the pipe or conduit, and at 2-foot vertical intervals to the top of the trench with the

final test at the surface/toplift. For utility mains conduct one (1) set of tests per 100 feet

of linear trench at specified depths and for service lines conduct one (1) test per every




312323 - 11

service line per utility type at specified depths. At a minimum, test intervals and quantities

shall meet or exceed the requirements of the local utility agency.

D. When testing agency reports that backfills have not achieved degree of compaction specified,

scarify and moisten or aerate, or remove and replace soil to depth required; recompact and

retest until specified compaction is obtained.

3.13 PROTECTION

A. Protecting Graded Areas: Protect newly graded areas from traffic, freezing, and erosion. Keep

free of trash and debris.

B. Repair and reestablish grades to specified tolerances where completed or partially completed

surfaces become eroded, rutted, settled, or where they lose compaction due to subsequent

construction operations or weather conditions.

1. Scarify or remove and replace soil material to depth as directed by Owner’s

Representative; reshape and recompact.

C. Where settling occurs before Project correction period elapses, remove finished surfacing,
