5.9 Compacting MiMUre
5.9.1 Provisions Applicable to Ali Types
a. Equipment and Sequence: For each paving or leveling train in
operation, the Contractor shall furnish a separate set of rollers.
with their operators. The rolling shall be done in the following
sequence, with the equipment a shown, unless otherwise
permitted by the Engineer of Record, with the concurrence of
the Department of Public Works.
(~) Seal rolling. using tandem steel rollers weighing 5 M 12
tons, and following as close behind the spreaders as is
possible without pick-up, undue displacement or blistering
of the material.
(2) Rolling with self propelled pneuma[ic-tired rollers, following
se behind the seal rolling es the mu will permit. The
rolleroshall cover every podlon of the surface with at laaet
five passes.
(3) Fnel mlling with the 5 to 12 ton tandem steel rollers, to be
done after the seal rolling and pneumatio-tiretl rolling have
been completed, but before the pavement temperature has
dropped below 1T5 degrees F.
b. Compaction at Crossovers, Intersection, etc: When a separate
paving machine is being used to pave the crossovers, fhe
ompactlon of the crossovers may be done by one 5 [0 10 ton
tandem steel roller. If crossovers, intersections and acceleration
and deceleration lanes are placed with the main run of paving, a
traffic roller shall also be used In the compacflon of these areas.
5.9.2 Rolling Procedu_
The initial rolling shall be longitudinal. When the lane being placed Is
adjacent to a previously placed lane, the center joins shall be pinched
or rolled, prior to the mlling of the rest of the lane.
After the rolling or pinching of fhe centerJoint, the rolling ehall continue
ss the mat by overlapping each previous roller path by a[least
ne-half the width of the roller wheel. The motion of iha roller shell be
nough to avoid displacement of the mixture, and any
displacement shell be corrected at once by the use of rakes, and the
addition of 4resh mtxlure if required Flnel rolling shell be contlnuatl
until all roller marks are eliminated.
a. Speetl of Rolling: Roiling with the self-propelled, pneumatic-tired
rollers shall proceed et a speed of 8 to 10 mliea per hour, and the
ered by each roller shall not be more than 4,000 square
yartlscper hour, except that (or Type 5 Asphaltic Concrete, this
maximum rate of coverage shall be 3,000 square yartls per hour.
b. Number of Pneumatic tired Rollers Requiretl: A sufficient number
of self-propelletl pneumatiotlred rollers shall be used to assure that
the rolling of the surface for the requlretl number of passes will not
delay any other phase of the laying operation nor result in excessive
cling of the mixture before the rolling Is complete. In the event
[haf the roiling falls behlntl, the laying operation shall be
tliscontinued until the rolling operations are aufFlGently caught up.
c. Compaction of Areas Inaccessible to Rollers: Areas which are
ssible to a roller (such as areae adjacent to curbs, headers,
gutters, bridges, manholes, eYC.) shall be compacted byihe use of
hand tamps or other satisfactory means.
d. Rolllr~q Patching antl Leveling Courses: Self-propelled
pneumatic-timd rollers shall be used for Na rolling of ell palohing
and leveling courses.
e. Correcting Defects- The rollere ehall not be allowetl to tleposii
gasoline, oil or grease onto the pavement. and any areas tlamagetl
by such tleposits shall be removed and replaced as directed by the
Engineer of Record. While rolling is in progress, the surface shall
be tested continuously antl all tliscrepancies corrected to comply
with the surface requirements. All drippings, fat orlean areas antl
defective construction of any description shall be removed and
replacetl. Depressions which develop before the completion offhe
rolling.. shall be remedied by loosening the miMUre and adding ne
mixture to bring the depressions to a true surface. Should any
tlepression remain after the final compaction has been obiained-
the full depth of the mixture shall be removetl antl replaced wish
suffcieni new mixture to form e true and even surface- All high
spots, high joints and honeycomb shall be correctetl as directed by
the Engineer of Record. Any mixture remaining unbontletl after
ling shall be re vetl and replaced. Any mixture which
becomes loose or broken, mixetl or coated with dirt or in any way
defective. prior tc laying the weenng course, shell be removetl antl
replaced with fresh mixture, which shall be immediately compacted
to conform with the surrounding area. Areas of detective surface
may be repairetl by the use of intllrect heat. No method of repair
involving open-flame heaters shall be usetl.
f. Provisions Applicable to Shoulder Pavement Only: Shoultler
pavements witler than three feet shall be compactetl by the use of
equipment of the type required for other asphaltic c Crete
pavements. Compadlon of asphaltic conorete three fee[orlass in
width, shell be done by the u of tantlem steel rollers not
eeding 12 tons in weight. Other compaction in such restrictetl
widths shall be by the use of any type of rubber-firetl equipment
the Contractor may elect to use, approvetl by the Engineer of
Recortl, with the concurrence of the Department of Public Works.
5.9.3 Density Required for Asphaltic Concrete Pavement After final
ompaction, the density shall be at least 96% of the laboratory
eompacied denslfy of the paving mixture for that day's production.
5.10 Joints
5.10.1 Transverse Joints: Placing of the mixture shall be as continuous as
possible antl the roller shall not pass over the unprotectetl antl of the
freshly laid mixture except when the laying operation is to be
discontinued long enough to permit the mixture to become chilled.
When the laying operation is thus interrupted, a transverse ~olnt shall
be c nstructetl by cutting back on the previous run to expose the full
depth of the mac.
5.10.2 Longitudinal Joints: Where only a portion of the witlth of pavement is
to be laid antl openetl to tratfc, longitudinal joints shall be formed by
rollingthe exposed edge of the strip frst laid. When the atllaceni strip
onstvcted, the Engineer of Record may require the etlge of the
mixture in place to be trimmed back to expose an unsealed or granular
vertical surface. Where the strip first laid Is closetl io traffc, the etlge
shall not be sealetl bu[ shall be left vertical and the atljacent strip
placed against i[ without trimming.
5 10.3 General: When (rash mixture is laid against the exposed etlges of
jointe (trimmed or foamed as provitletl above), It shall be placed inclose

dated with entrance'mto antl exit from [he system, friction through
the system, and turbulence n the 1ntlNidual manholes/catch-0esins~unction
boxes within the system. The energy lasses associated with the turbulence in
the intlividual manholes are minor for an open channel or gravity storm sewer
system and can typically be overoome by adjusting (Increasing) the upstream
pipe invert elevations in a manhole by a small amount. However, the energy
dated with the Nrbulence in the individual manholes can be
signif cant for a pres urchargetl storm sewer system and must be
accounted for in establishing a reasonable hydraulic 9radien~ line.

SUBDIVISION PLANNING
OBJECTIVES
The objectives of the Ciry of Longwood In subdivision planning areto promote health,
safety end welfare In anhanoing the quality of Ilfe for tts rasitlents. This dictates a
safe and effcient access and traffic circulation system. The following principles are
to be considered in accomplishing these objectives.
1.1 Adequate Veh'cular and Pedestrian Access
Adequate vehicular and pedestrian access shall be provitletl for all parcels.
Street widths, sidewalk placement, patterns of streets and number of
tntersactlons shau take mto constleratton both sefery and efnclency of access
to abutting parcels. Every parcel shall abut an approved private street, an
approved access easement. or a street dedicated to, and accepted by the City
for maintenance-
1.2 M'ri zafon of Traffic Mov ants Through Local Streets
Through 1raRlc shall be dlscoureged through the use of discontinultles in local
street patterns by offsetting local street lnterseclions and by channeling or
controlling street medians along peripheral major or collector streets. This will
reduce the amount and speed of traffc, thereby making local streets more
safe and amenable to residents.
1.3 I g d C ' t St 1 N b 'nq ands
A consistent and logical pattern shall be developed to simplify local street
ming and numbering, to assist visitors in locating addresses and facilitate
access by emergency vehicles, delivery vehicles, etc.
1.4 E(fdent Tragic Circulation and Development Patterns
Driv ways. intersection placement and access shall be controlled so that no
parcels require direct access to major or collector streets Provisions shall be
provitletl for con6naing existing principal streets from ed]oimng arses through
subdivisions. Where streets are extended to subdivision boundaries and
abut either undeveloped adjoining land, or connect to collector or arterial
roads, the location of the subdivision street shall be coordinated with the Clty
Administrator to facilitate future street development In adjoining areas, for
eral efficiency of traffic Flaw and (or safety considerations of future
m~araecugne.
1.5 Design for PUroose lntentled
Local streets shall not be overtlesigned or overbuilt, i.e: extra witlth, higher
