Payne & Dolan's principal product is asphalt mix, which consists of a predetermined combination of crushed aggregate, air and liquid asphalt cement. Proper design of the mix is necessary if the pavement is to handle design loads and special customer requirements.
Payne & Dolan’s asphalt mix design process is handled at state qualified labs (Illinois, Michigan and Wisconsin). These labs determine the proper type, size, shape and combination of aggregates and liquid asphalt in each mix well as conduct acceptance, sampling and testing of all materials used for those States’ State Truckline and National Highway system projects. In fact, Payne & Dolan had the first laboratory in the State of Wisconsin to receive national accreditation from AASHTO (American Association of State Highway and Transportation Officials).
Production of each specially designed asphalt mix is handled at Payne & Dolan plants strategically located to serve our customers as well as maintain quality. Quality Control (QC) monitors product production to ensure mix design requirements and customer specifications are met. HMAs are generally produced in large quantities and then trucked to the hopper of an asphalt paving machine at the jobsite, leveled with the paver and compacted to a specified density with rollers.
Asphalt vs Concrete
Asphalt surfaced pavements have been shown to have several benefits over concrete. Asphalt surfaced pavements have been shown to be quieter than concrete surfaced pavements, reducing noise pollution by 1 to 10 decibels. This has a quality of life benefit to those who live near roadways. Also, by reducing the need for costly noise barrier walls, asphalt reduces costs for construction and raw materials.
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. Quite a cost when you consider that projects constructed from concrete typically impede traffic 24 hours a day. By choosing an asphalt pavement structure,
- 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
Innovation has Benefits
Quality innovations can make all the difference in a paving project. Payne & Dolan constantly works to improve both the pavements themselves and the ways they are installed — extending pavement life, improving fuel efficiency for motorists and even lowering noise pollution.
Warm-mix Asphalt - Warm-mix asphalt (WMA) is a newly emerging technology in the asphalt paving industry. Consistent with our commitment to innovation and environmental responsibility, Payne & Dolan is investigating the possibility of using warm-mix technologies to complement our existing asphalt mix offerings.
- WMA reduces energy/fuel use in production and placement
- Recycled Asphalt Pavements (RAP) can still be used in WMA
- WMA reduces emissions
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
Perpetual Pavements - Perpetual pavements perform better, last longer, and carry lower life-cycle costs. 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.
Smooth Pavements - Smooth pavements are not only more enjoyable for the motorist to travel on, State agencies are very aware of their benefits. Smooth pavement surfaces result in a public perception of high job quality plus benefit the environment by reducing fuel consumption and extending pavement life. Payne & Dolan’s extensive testing and tracking of pavement smoothness has shown:
- Fuel efficiency increases by 5% on smooth pavements
- Smooth pavements extend pavement life by 10%
- Less wear on a vehicle traveling on smooth pavements
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
