Roadway Machine Placed Hot Mix Asphalt (9.5mm, 12.5mm, 19mm)

These items shall cover the complete placement of a uniformly blended, homogenous mixture of Hot

Mix Asphalt on an approved base. The Contractor shall compose the Hot Mix Asphalt with aggregate,

performance graded asphalt binder, and mineral filler if required. The Contractor shall size, uniformly

grade, and combine the aggregate fractions in proportions that provide a mixture meeting the grading

requirements.

The acceptable temperatures of all mixes is 300 ̊ F(+/- 25 ̊ F) at the time of delivery in the truck or in the

paver; unless other temperatures are approved prior to paving.

Page 4: CITY OF SACO, MAINE2021. 3. 8. · HMA plants shall conform to AASHTO M156. The scales shall be inspected and sealed by the State Sealer annually to verify their accuracy. Plant scales

The Contractor may utilize either a 64-28 or 58-28 performance graded asphalt binder.

HMA plants shall conform to AASHTO M156. The scales shall be inspected and sealed by the State

Sealer annually to verify their accuracy. Plant scales shall be checked prior to the start of the paving

season, and each time a plant is moved to a new location. An approved automatic ticket printer system

shall be used with all approved automatic Hot Mix Asphalt plants. The Contractor shall dry and heat the

aggregates for the Hot Mix Asphalt to the required temperature. The Contractor shall properly adjust

flames to avoid physical damage to the aggregate and to avoid depositing soot on the aggregate. The

Contractor shall combine the dried aggregate in the mixer in the amount of each fraction of aggregate

required. The Contractor shall measure the amount of PGAB and introduce it into the mixer in the

amount required. The aggregate shall be coated completely and uniformly with a thorough distribution

of the PGAB. The resultant material shall be a uniformly blended, homogenous Hot Mix Asphalt

mixture.

The City of Saco will determine when Hot Mix Asphalt may be applied. If weather conditions change

during a paving operation, paving may be suspended by the Contractor or City until the City determines

it is acceptable to pave. The City will not pay for any Hot Mix Asphalt not placed or wasted because of

weather interruptions.

Trucks used for hauling Hot Mix Asphalt Pavement shall have tight, clean, and smooth metal dump

bodies, which have been thinly coated with a small amount of approved release agent to prevent the

mixture from adhering to the bodies. Solvent based agents developed to strip asphalts from aggregates

will not be allowed as release agents. All truck dump bodies shall have a cover of canvas or other water

repellent material capable of heat retention, which completely covers the mixture. The cover shall be

securely fastened on the truck, unless unloading.

Pavers shall be self-contained, self-propelled units with an activated screed (heated if necessary) capable

of placing courses of Hot Mix Asphalt Pavement in full lane widths. The Contractor shall operate the

paver in such a manner as to produce a visually uniform surface texture and a thickness. The paver shall

have a receiving hopper with sufficient capacity for a uniform spreading operation and a distribution

system to place the mixture uniformly, without segregation in front of the screed. The screed assembly

shall produce a finished surface of the required evenness and texture without tearing, shoving, or

gouging the mixture. Pavers with extendible screeds shall have auger extensions and tunnel extenders as

per the manufacturer’s recommendations

Rollers shall be static steel, pneumatic tire, oscillatory, or approved vibrator type. Rollers shall be in

good mechanical condition, capable of starting and stopping smoothly, and be free from backlash when

reversing direction. Rollers shall be equipped and operated in such a way as to prevent the picking up of

hot mixed material by the roller surface. The use of rollers, which result in crushing of the aggregate or

in displacement of the Hot Mix Asphalt, will not be permitted.

The City may reject any equipment that they find to be defective or incapable of properly performing

quality work.

On areas where irregularities or unavoidable obstacles make the use of mechanical spreading and

finishing equipment impracticable, the Contractor shall spread, rake, and lute the Hot Mix Asphalt with

hand tools to provide the required compacted thickness. Solvent based agents developed to strip asphalts

from aggregates will not be allowed as release agents.

Immediately after the Hot Mix Asphalt Pavement has been spread, struck off, and any surface

irregularities adjusted, the Contractor shall thoroughly and uniformly compact the Hot Mix Asphalt by

rolling. The Contractor shall roll the surface when the mixture is in the proper condition and when the

rolling does not cause undue displacement, cracking, or shoving. The Contractor shall prevent adhesion

of the Hot Mix Asphalt to the rollers or vibrating compactors without the use of fuel oil or other

petroleum based release agents. Solvents designed to strip asphalt binders from aggregates will not be

permitted as release agents on equipment, tools, or pavement surfaces. The Contractor shall immediately

correct any displacement occurring as a result of the reversing of the direction of a roller or from other

causes to the satisfaction of the City. Any operation other than placement of variable depth shim course

that results in breakdown of the aggregate shall be discontinued. Any new pavement that shows obvious

cracking, checking, or displacement shall be removed and replaced at no cost to the City. Along forms,

curbs, headers, walls, and other places not accessible to the rollers, the Contractor shall thoroughly

compact the Hot Mix Asphalt with mechanical vibrating compactors. The Contractor shall only use hand

tamping in areas inaccessible to all other compaction equipment.

Rolling methods shall be used to compact the mix to a target of 95% its maximum density.

The paver shall maintain a uniform head of HMA during transverse and longitudinal joint construction.
