ub
-
grades and foundation soils from freezing temperatures and frost. Remove

accumulate in excavations. Do n
ot use excavated trenches as temporary
drainage ditches.

3.4

EXISTING UTILITIES

A.

Owner will arrange for disconnecting and se
aling indicated utilities that serve existing structures
before site clearing, when requested by Contractor.

When testing agency reports that sub
-
grades, fills, or backfills have not
achieved degree of compaction specified, scarify and moisten or aerate, or

free of distortions. Straighten bends, kinks, and other irregularities, or replace units as required
before placement. Set mats
for a minimum
2

from joint to
joi
nt unless otherwise approved by Architect.

B
.

of
cracks or defective areas. Fill drilled core holes in satisfactory paving areas with

Portland
cement concrete bonded to

paving with epoxy adhesive.

C
.

Protect concrete paving from damage. Exclude traffic from paving for at least 14 days

after
placement. When construction traffic is permitted, maintain paving as clean as

possible by
removing surface stains and spillage
of materials as they occur.

D.

Maintain concrete paving free of stains, discoloration, dirt, and other foreign material.

Sweep
paving not more than two days before date scheduled for Substantial

E.

Clean off excess joint sealant
or sealant smears adjacent to joints as the Work

progresses, by
methods and with cleaning materials approved in writing by

manufacturers of joint sealants and of
products in which joints occur.

F.

Protect joint sealants, during and after curing period, f
rom contact with contaminating

substances and from damage resulting from construction operations or other causes

so
sealants are without deterioration or damage at time of Substantial Completion. If,

despite such
protection, damage or deterioration occ
urs, cut out and remove damaged

or deteriorated joint
sealants immediately and replace with joint sealant so installations

in repaired areas are
indistinguishable from the original work.
