ROAD RESTORATION

PART 1 - GENERAL
1.01 WORK INCLUDED:

Furnish all labor, equipment and materials required to install crushed gravel base
course, bituminous concrete pavement courses including temporary and permanent trench
paving curbing, sidewalks, disposal of excess material at the City landfill and restoration of
pavement markings in roadway areas where spot sewer repairs are required, manholes are to
be installed, manhole frames and covers are replaced, or as ordered by the Engineer and as
specified herein.

ACCEPTANCE

3.

Prior to final acceptance, any defects that may affect the integrity or strength
of the pipeline is the opinion of the Engineer shall be repaired by the
Contractor at no additional cost to the Owner.

Pipeline shall be true to line and grade, with no visual bulges, sags,
protrusions, deflections, offset joints, leaking joints, or other visible
infiltration, or other defects that would impair the intended use of the
completed pipeline.

3.08 FINISH

The finished CIPP shall be continuous over the entire length of any section
and be as free as commercially practicable from visual defects such as
foreign inclusions, dry spots, pinholes and delamination.

3.09 TESTING, INSPECTION AND ACCEPTANCE

A. MATERIAL TESTING

1. All material testing shall be performed by a registered independent, third-
party laboratory, and paid for by the Contractor.

5. This will be accomplished using a computer and data base that are tamper proof.
During the curing process, infrared sensors will be used to record curing data that will
be submitted to the Engineer with a post CCTV inspection on DVD.

3.04 PRE-LINER/OUTER FILM/OUTER LINER

The manufacturer will test the raw materials and liner materials at various
stages of manufacturing on every liner, including taking samples of every
finished liner and conducting test for e-modulus, tensile, wall thickness
and porosity.

Fiberglass materials must be “direct sized” to enhance the fiberglass/resin
bond. Certification of this coating and its compatibility with the resin
system used is required.

All wet-out or impregnation of the Tube must be done in an EPA-
regulated, quality-controlled facility. Documentation of EPA permitting
must be submitted with all qualified bids. No “over the hole” or “on-site”
wet-out is allowed. For products that are cured with hot water, the wet-out
must be conducted within 300 miles of the job site considering the time-
sensitive characteristics of thermal-cured products.

FIBERGLASS TUBE

B.

by solids, grit, and/or sand. The cured tube shall also be resistant to
corrosion due to acids and gases such as sulfuric acid, carbonic acid,
hydrogen sulfide, methane, and carbon monoxide. The Cure-In-Place-
Pipe system shall utilize thermosetting resins which will withstand the
corrosive effect of the existing residential commercial, and industrial
sewage effluents, liquids and/or gases.
