Payne & Dolan » About Us » New Technologies

The world needs sustainability and Payne and Dolan, Inc. is committed to being a leader in that quest. We have researched new technologies, methods, materials, training, and equipment needed in order to help us usher in the "Green Era". These Steps are the foundation of building sustainable development, conserving energy, and material resources, reducing the carbon footprint of our industry, and improving the quality of the pavements that all Americans rely on.

ASPHALT PAVEMENTS - CLOSING THE LOOP

In the past, the materials we used in our daily lives followed a linear path. They were extracted, manufactured, used, and discarded. As landfills begin to fill up, and seemingly inexhaustible natural resources begin to dwindle, we are realizing the negative effects humans are having on our natural environment. By reducing raw material and energy consumption and reusing still viable materials in new ways, we are bending the linear path into a circular path and "closing the loop". In other words, we can provide for the needs of today without compromising the ability of future generations to meet their own needs.

Asphalt pavements provide great opportunities for recycling, reducing fuel consumption, and lowering emissions. Payne and Dolan, Inc. is committed to using the latest materials and procedures to increase sustainability without losing our industry standard of high quality, long-lasting, and safe asphalt pavements.

By utilizing these waste products, we can divert the waste stream away from
landfills and into high quality pavements. The recycled content of many
asphalt mixes may also earn your project credits towards LEED® certification.

RECYCLED ASPHALT PAVEMENTS:

Payne and Dolan, Inc. has been recycling asphalt pavements into new products for decades. As our society continues flowing toward sustainable development, we will continue to use recycled asphalt pavement (RAP) and work to increase the amount of RAP we put into pavements. This is just one of the many ways Payne and Dolan, Inc. is committed to meeting the needs of the present without compromising the ability of future generations to meet their own needs.

Asphalt pavements are 100% recyclable
They are the most recycled product in America
Recycled asphalt pavement is a one-to-one replacement of raw materials
Recycling asphalt pavements saves landfill space

RECYCLED ASPHALT SHINGLES:

Payne and Dolan, Inc. does not limit its recycling efforts to Recycled Asphalt Pavements. Products recycled from other industries and incorporated into new asphalt pavements include tires, glass, and foundry sand. One of the more recent developments in waste material reuse involves Recycled Asphalt Shingles (RAS). At Payne and Dolan, Inc. we are doing our part to stop this waste of an environmentally sensitive, economically viable and recyclable product.

10 million tons of waste shingles are produced each year in the United States
9.5 million tons (95%) of this waste goes into landfills
Recycling asphalt shingles reduces demand for asphalt cement
Using RAS lowers construction costs
Recycling asphalt shingles saves landfill space

RECYCLED OIL:

Reuse is not limited to the material in our pavements. The process of making hot mix asphalt requires the drying of the aggregate before it is mixed with asphalt cement. Most of our asphalt plants use recycled oil as a fuel source for heat generation.

Recycling used oil reduces petroleum demand
It is 100% recycled material
Recycling used oil reduces need for oil disposal

WARM-MIX ASPHALT:

Warm-mix asphalt (WMA) is a newly emerging technology in the asphalt paving industry. Payne and Dolan, Inc. was quick to take it upon ourselves to investigate the possibility of using warm-mix technologies to complement our existing hot mix asphalt offerings. As with hot mix asphalt, WMA may be able to earn you points towards LEED® Certification.

WMA reduces energy/fuel use in production and placement
RAP can still be used in WMA
WMA reduces emissions

POROUS PAVEMENTS:

Porous pavements can provide multiple environmental benefits. Full porous pavements placed over a recharge bed aids in storm water management. Instead of water running off the pavement and into storm drains, or into surface waters, storm water is allowed to drain through the pavement and then infiltrates the soil. This aids in overall site design and layout of a property. Many local governments have enacted regulations that limit the amount of impervious surfaces and impose minimum on-site storm water detention capacity. LEED® credits may also be obtained for using porous pavements.

Less site design constraints
Porous pavements reduce runoff/increase water filtration
They also improve water quality
Urban heat island effects are reduced by porous pavements
Porous pavements increase water detention capacity

COURSE GRADED ASPHALT MIX:

Course graded pavements are utilized on projects with thicker layers to provide increased structure. Using a course graded mix can also be a more economical option as there is less of a demand for petrolium products.

More economically viable
High tensile strength
No rutting
Stone on stone strength

STONE MATRIX ASPHALT PAVEMENT:

Stone matrix asphalt (SMA) pavements are increasingly utilized on highway projects. SMA provides a strong, long lasting pavement option for high traffic volume applications. SMA is an open-graded pavement type that is paved over traditional lower layer asphalt mixes.

SMA increases safety by reducing vehicle spray
SMA is a strong pavement for high traffic and heavy truck routes
Less chance a vehicle will hyrdo-plane on a SMA surface

REUSING THE RUBBLE:

Rubblization is a sustainable pavement reconstruction technique. Failing concrete pavement is left in place and rubblized (fractured) and used as the base for a new asphalt pavement.

Rubblization decreases construction time
Rubblization reduces need for new base material
It also eliminates trucking of new base material
Recycle concrete in place
Saves time & money

SMOOTHING OUT THE PATH TO SAVINGS:

Smooth pavements are not only more enjoyable for the motorist to travel on; they also reduce energy consumption and extend pavement life! Payne and Dolan, Inc. has completed extensive testing and tracking of pavement smoothness on a number of various projects. State agencies are very aware of the benefits of smooth pavement surfaces both in the obvious public perception of job quality and the more subtle environmental benefits of reduced fuel consumption and extended pavement life.

Fuel efficiency increases by 5% on smooth pavements
Smooth pavements extend pavement life by 10%
Less wear on a vehicle traveling on smooth pavements

PERTETUAL PAVEMENTS - EXTENDING THE LIFE CYCLE

Perpetual pavements perform better, last longer, and carry lower life-cycle costs. Perpetual asphalt pavements are designed and constructed to last longer than 50 years! These pavements are 8 ½" to 14" of HMA built with a minimum of three layers. The design keeps distresses confined to the top of the pavement so that only a periodic renewal of the surface is needed.

Longer design life
Lower life-cycle costs
Distresses confined to top layer

QUIETER - TURNING THE VOLUMN DOWN

Asphalt surfaced pavements have been shown to be quieter than concrete surfaced pavements. This has a quality of life benefit to those who live near roadways. Also, by using lower noise asphalt surfaces, construction cost and raw materials needed are reduced.

Asphalt surfaces lower noise pollution by 1 to 10 decibels
Costly noise barrier walls are reduced

SHORTENING THE DELAY

The process required to reconstruct most roads creates a certain amount of inconvenience for the traveling public. Asphalt pavements involve much less user delay than concrete pavements. On a typical highway project user delay has been measured to cost $3,000 per hour or more. By choosing an asphalt pavement structure, traffic can flow freely when crews are not present. Projects constructed from concrete typically impede traffic 24 hours a day.

Less traffic congestion is experienced on asphalt paved projects
Less fuel is wasted by vehicles stuck in traffic
Asphalt paving requires fewer road closures
Scheduling flexibility is greater with asphalt pavements

SKIMMING THE SURFACE - ULTRA THIN OVERLAYS:

Ultra-thin overlays are used in a variety of applications where a thin surface cross section is needed. Ultra-thin overlays can be a cost effective option for extending the life of an existing pavement structure.

Ultra-thin overlays reduce the amount of material used
Cost effective alternative to full reconstruction
They can repair wheel ruts, ride quality, and light to moderate cracking
