Phase .. Final Design

• Summary

East Maricopa F100dway Reach-4:

Based on the comments and recommendations offered by the WNTC in thePreliminary Design Review Report, we have reconsidered and find that a two (2)inch wide joint, with installation temperature restrictions, will provide fora better design.

It should be stressed that a safety factor of 1.0 does not put a properlyinstalled joint at the edge of failure, but at its working capacity asdetermined by ASTM.

We will also monitor multiple joint widths (existing, 2" and 3") during thetesting period to gain experience in the behavior of low modulus silicones.

Basis for Design

Preliminary Design Review Report 5/26/88Joint Movement Calculations by LNS 5/16/88Facsimile Transmittal Sheet from LMS 6/2188

Performance Time

The temperature restrictions put on the Contractor for cutting and appling

•

sealant to the joints for EMF R-4 should not increase normal performance time• since he will be able to sequence his work between the Signal Butte F100dway,

which has no restrictions.

Bid Schedule

The alternative for additional one inch joints on EMF R-4 will no longer beconsidered since it would not be economically feasible when compared to therevised two inch joints.

The items below and details on the attached drawing are whatwe believe are neces.ary ~or Inclusion in the specificationsand drawings to adequately monitor the concrete temperatureduring the joint repair for Reach 4. In the interest oftime this information is being sent by FAX.' Other commentsconcerning this job were sent by Speed Memo from LelandSaele to Don Paulus on 5/26/8S.

Items to include in the specification covering temperaturemonitoring of the concrete:

The contractor shall measure and record dally thet~mperature of the eMisting concrete channel liningbeginning 24 hour'S prior to saw cutting or instal lation o~

Joint sealant at any Joint and ending at the completion ofal I work. A minimum of two temperatur~ readings wi I I berecorded each day corresponding with the approximate highand low temperature of the concrete during the working day"

The temperature of. the concrete shall be measured byinstall ing sensors two inches below the concrete surface as~hown on the drawinss. The sen50rs shal I be instal led in~uch a manner as to insure thermal conductiVity between thes~n~or and the surrounding concrete and to ~ccurately

measure the temperature of the concrete at the Z inch depth.Lt,;.cat ion of the tii&ll!iOr shall be adequa.tely mat"ked aridprotected to prevent accidental damage. Marking orprotective barriers shall not alter normal temperatureconditions at ~ensor location.

The sensor shal I be a thermocouple or simi lar device thatcan be connected to a portable readout instrument. Thereadout unit shal I be an easi Iy portable (hand held),battery powered instrument. The"readout unit and sensorGt,a I I have an accuracy with i n ~ Z des."ee s Fa.-er,he i t over arnjr,imurn temperatut"e rar,ge of (I'F to 250"':" The tOeSpC1rlsetime fo~ readings shal I be less than 15 second~. Thereadout instrument complete with connectins leads andinstruct jon manual shal I become the property of thegovernment at the completion of work.

The contractor ahal I p~ovid. his plan, for installation ofsensors. monitoring temperature and type of equipment to beused, for approval, 10 days prior to installation.

Depending on how the specifications are prepared thefol lowing sentence could follow the 'lrst paragraph above or

b~ the alternatewordlns If the Information above isrepeated in another item specifically for the test section.

"During the installation and 10 day monitoring period of thetest section, sufficient readings shall be taken tod .. t ....m i ne thr: apprOH imateh i Sh and I·ow ternper·.,ture extremesof the concrete within any 24 hour period.»

A; Design - The proposed design offers the contractor twooptions: (1) 3 inch wide Joints at 100 foot intervals or <Z)one inch wide Joints at 33 foot intervals.

Both designs should provide for minimal sealant stress fromJo i nt movement.

On theother hand, one inch Joints reduce the exposure of sealantto a minimum but increase the total Joint length by ZOOpercent~ We have no experience or definitive informationindicating that a Joint over a given size should or shouldnot be used.

silicone conforming to the requirements of ASTM C-920 and

shall tolerate submergence by intermittent flood flows.

The sealant shall have the capability to withstand without

failure an increase of 100 percent and a decrease of 50

percent of the joint width as measured at the time of

application when tested in accordance with ASTM C-719.

The elongation shall be a minimum of 800 percent without

failure when tested in accordance with ASTM D-412, and 500

percent without adhesion failure when tested in accordance

with ASTK C-719.

Bond Breaker/

Backer Rod: A bond breaking material shall be compatible with the

sealant and conform to the sealant manufacturer's

(ePrimer:

requirements.

The primer shall insure that proper bond exists between the

sealant and the prepared concrete surface and will resist

intermittent flood flows. The primer shall conform to the

requirements of the sealant manufacturer and the material

data submitted to the Contracting Officer for final

approval.

3. SURFACE PREPARATION AND APPLICATION

The sealant manufacturer's representative shall be present during initial

installation to insure. that proper surface preparation, application, and

handling techniques are being used by the contractor.

Sealant Removal and Refacing:

All old sealant and/or joint filler shall be completely removed from the

joint to the depth of the saw cut. The removal of sealant or filler from

the joint sidewalls may be done with any suitable procedure that does not

damage the j~int surface or concrete. Power driven wire brushes will not

be permitted. The new joint shall be saw cut as required to attain the

width and depth shown~n the drawings. Concrete cutting equipment shall

be equiped with carbide or diamond blades. A water wash with a minimum

operating pressure of 90 psi is permissible for the initial removal of

contaminants and dried laitance. Flushing shall be done in one direction

only.

Cleaning:

The top one inch of each joint face shall be sand-blasted. The sand­

blasting nozzle must be held at an angle or fitted with deflectors to

direct the sand against the joint face within one or two inches of the

pavement." A minimum of one pass shall be made for each joint face.

After sand-blasting, the joint shall allowed to air dry for a minimum of

24 hours, under natural drying conditions. Just prior to priming, the

joints shall be be air-blasted to remove sand and dust. Air compressors

used for sandblasting and airblasting shall be equiped with traps to

remove moisture and oil from the air. Air-blasting shall be done in one

direction only.

The joint is considered to be clean when no residue is evident after

rubbing your finger or dark lint free cloth along the cleaned dry joint

face. The joint shall be completely dry before proceeding with the

application of primer or sealant.

Sealant Inst~llation:

Apply primer coat to the clean, dry joint surfaces by brushing or spraying

the top one inch of each joint face. The primer shall be allowed to dry

in accordance with the manufacturer's recommendations.

•(

.. "-'..- -.. --' ...•.. ..-.-_._--_._---~--------

Bond breaker .aterial shall be placed such that it will prevent adhesion

of the sealant with the bottom surface of the prepared joint. and also

establish the cross section needed for the application of the sealant:

Installation of the bond breaker shall be done in such a manner that it

will not force extrusion of the sealant during closure of the joint.

Joints must be clean and dry when the sealant is installed. Drying of the

joint surfaces may only occur from natural weather conditions.

During the sealant placement the nozzle of the sealant applicator shall be

moved steadily along the joint. pushing the sealant ahead to form the

required cross section. The minimum and maximum temperature at

installation should be in accordance with the manufacturer's

recommendation unless specified otherwise in Section 6.

Immediately after placement and before a skin forms. the sealant shall be

tooled. forcing it onto the bond breaker surface and against the joint

faces. The finished tooled surface shall be recessed below the concrete

surface as d~tailed on the drawings. Excess sealant on the pavement

surface sha~l be and removed.
