Within Township Roads. When excavation of an existing Township Road is required, it shall be done in accordance with requirements of the Township Road opening permit. The backfill shall be as follows:
(a) 
Prior to excavation, all trenches in the existing road are to be saw-cut the full depth of the bituminous paving.
(b) 
Backfill with PennDOT 2A or 2RC crushed stone compacted in eight-inch layers to finished grade and meeting the compaction requirements of Subsection 1G(2)(d).
(c) 
Top existing trench with two inches of compacted bituminous stockpile patching material (cold patch).
(d) 
After 90 days of settlement time, the cold patch and backfill material shall be removed and the trench shall be saw-cut an additional one-foot beyond the initial cut and paved in accordance with Township specifications.
(3) 
All Other Areas.
(a) 
Backfill for the remainder of the trenches or excavations shall be approved material and free from organic matter, large or frozen lumps, or stones over 10 inches in their largest dimensions. Stones which are used in backfilling shall be so distributed through the mass that all interstices are filled with fine material.
(b) 
The material shall be moistened or dried, if necessary, to obtain the required compaction. Backfill material shall be approved by the Engineer. Special care shall be taken in placing the backfill. Particular care shall be used to obtain thorough compaction under the haunches and along the sides of the top of the pipe.

Backfill shall be compacted to a density satisfactory to the Engineer. A thoroughly and satisfactorily compacted backfill is defined as having a minimum dry density of 95% of the maximum density. The maximum density is the maximum dry weight density in pounds per cubic foot as determined by the AASHTO Standard Density Test, T 99, Method C. Where the backfill material consists of sand or silt containing less than 20% by weight of particles passing the No. 200 mesh sieve, a minimum dry density of 100% of maximum density will be required.
(b)

c) 
Prior to construction of the bituminous concrete wearing course, all trench settlement areas shall be excavated to the depth of the unconsolidated or unacceptable backfill material, as determined by the Township Engineer. The excavated areas shall be backfilled with crushed stone material compacted in maximum lifts of six inches to a minimum compaction of 97%, after which the base course shall be replaced.
d) 
The bituminous concrete wearing course shall not be constructed until at least two years after the base course is completed.
e) 
The maintenance period for the roadway shall be extended to three years.
(c) 
Placement of subbase and bituminous concrete base course for proposed roads within Township right-of-way where the trenches were backfilled with crushed stone can proceed following completion of backfill.
H. 
Gravity Sewer Pipe Testing.
(1) 
All sewers must be laid true to line and grade between manholes and must pass a visual test of straightness. If infiltration in any test section exceeds 50 gallons per inch diameter of pipe per mile of length in 24 hours, or if exfiltration exceeds 50 gallons per inch diameter of pipe per mile of length in 24 hours, the system will not be accepted or certified for use until corrections are made. No infiltration or exfiltration will be permitted within 200 feet of a water supply source. All infiltration and exfiltration tests in sanitary sewer lines and manholes must be performed by the developer and observed by the Township Engineer.
(2) 
If the pipe to be tested is submerged in ground water, the contractor shall use low pressure air testing facilities to determine the acceptability of the test section. Air testing shall be performed in the following manner:
(a) 
If the pipe to be tested is submerged in ground water, insert a pipe probe by boring or jetting into the backfill material adjacent to the center of the pipe and determine the pressure in the probe when air passes slowly through it. (This is the back pressure due to the probe). All gauge pressures in the test should be increased by this amount.
(b) 
Plug all pipe outlets with suitable test plugs. Brace each plug securely.
(c) 
Add air slowly to the portion of the pipe installation under test until the internal air pressure is raised to 4.0 psig.
(d) 
After an internal pressure of 4.0 psig is obtained allow at least two minutes for air temperature to stabilize, adding only the amount of air required to maintain that pressure.
(e) 
When pressure decreases to 3.5 psig, start stopwatch. Determine the time in seconds that is required for the internal air pressure to reach 2.5 psig.
(f) 
Minimum permissible pressure holding times for runs of single pipe diameter of eight inches, 10 inches, 12 inches and 15 inches and for systems in combination with trunk lines are indicated in the following tables. These tables indicate minimum holding time in seconds required for pressure to drop from 3.5 psig to 2.5 psig.

J. 
Mandrel Testing.

(2) 
Mandrel tests shall be conducted not less than 30 days after final backfill has been placed.
K. 
Low Pressure Sewer Testing.
(1) 
After the pipe laying is entirely completed, the joints in all pipe lines and appurtenances shall be capable of withstanding a static pressure (psi) of two times the operating pressure of the system for a minimum duration of 30 minutes. Tests of sections as they are completed are to be made by static water pressure in the presence of the Engineer.
(2) 
Extreme care shall be exercised during the testing to limit the possibility of property damage due to pipe failure. Temporary thrust blocks installed for testing purposes must be adequate for the required test pressure.
(3) 
Each section of pipeline shall be filled slowly with water, preferably 24 hours in advance of the time set for the test. Great care must be exercised to insure that all air is expelled from the section of line being tested prior to the test.
(4) 
Should the pipe line or appurtenances show any loss of water during the tests, within said pressure, the contractor shall immediately locate and repair the leak or leaks, at his own expense.
L. 
Highway/Railroad Borings.

Following installation, the steel casing insulator shall not be subject to maximum loadings greater than 30 lbs./sq. in. Sand or pea gravel, as approved by the Engineer, shall be placed to completely fill the void between the carrier and casing pipes.
(6) 
Steel casing insulators shall be installed within one foot of each side of all carrier pipe joints, within one foot of both ends of the casing pipe, and a maximum of 10 feet apart, or as dictated by the maximum load ratings of the steel casing insulators as approved by the manufacturer.
