Sustainable Pavement Program

Overall, ADOT views their Pavement Management System as contributing to sustainability by optimizing pavement life cycles to reduce costs, the environmental impacts of construction, and material usage. ADOT’s pavement team always considers sustainable pavements for its projects. The sustainable pavements are used when they are the best option available.  Pavement design life is a term that engineers use when they’re planning to build a new road or maintain an existing roadway. They’ll also use a number of years to go along with it, for example: 10-year pavement design life, 20-year pavement design life, etc. The phrase should not be taken to imply that a road is only being built to survive for a set number of years. What it does represent is the road’s age at which some preventative maintenance or reconstruction will be considered so the road can continue to be durable and useful for the traffic it’s serving. A lot is taken into consideration, soil condition, location, expected traffic levels and the area’s climate. All those conditions play a role in how the pavement is designed.

ADOT’s pavement management contributes to sustainability by enhancing roadway safety, optimizing pavement life cycles to reduce costs, while considering the environmental impacts of construction and material usage.

ADOT’s Quiet Pavement Program 
ADOT has completed its Quiet pavement program. The Federal Highway Administration has issued an updated memo to clarify its position on use of pavement as a noise abatement measure. The memo reiterates that regulations at 23 CFR 772 do not allow for the use of pavement type or surface texture as a noise abatement measure. FHWA will continue to consider pavements as contribution to the noise abatement measure if evaluated for the pavement's full life cycle. The FHWA will also allow new Quiet Pavement Pilot Projects that evaluate the pavement for its full life cycle, to avoid premature overlay of the pavement solely to restore the noise reduction. FHWA encourages highway agencies to continue researching their pavement types and surface textures and to construct those pavement in accordance with their agency's requirements. The FHWA will continue to investigate data used for its Traffic Noise Model and "average pavement type" for noise analyses on projects.
