Recycling has come a long way. Now, recycled can be better than new.
Reducing Environmental Impact while Improving Economics.
To achieve true sustainability, we address the environmental and economic impact of each pavement practice from start to finish. Consumption of resources like aggregate and oil: net energy expended at each stage; greenhouse gas emissions; dust pollution; waste generation; and transportation (such as import/export) are all part of the equation. Meanwhile, performance and economics must be equal or better.
Confronting the resource crisis, from rock to oil.
Gravel pits are scarring our landscape. Sky high aggregate and oil prices are the new reality. Our strategies to reclaim aggregates and recycle in-place asphalt eliminate the need for virgin rock. Oil usage is reduced too: fewer in-and-out truckloads mean less fuel consumed, and recycled aggregate mixes often require less oil-based emulsion.
Reducing emissions: from greenhouse gases to dust.
Our processes that re-use and rehabilitate in-situ materials, from pavement to soil, eliminate the cost, energy use, air pollution and disruption caused by importing and exporting materials to and from jobsites. The ratios are startling: 40 truckloads to 1 or better, versus conventional methods.
When asphalt recycling first started, it was inferior. Those days are long gone. Pavement Recycling Systems (PRS) is at the forefront of the advances in recycling technology and application.
The Federal Highway Administration has adopted an official policy on recycling. Builders and owners are recognizing the cost efficiencies and value of recycling strategies. Increasing material costs and environmental pressures have intensified the market need. Advanced technologies (such as sophisticated additives), specialized equipment, and years of proven performance have eliminated the risk. Recycling has come of age. Pavement Recycling Systems has been part of that evolution.
From project evaluation, to pulverization, to mixing, to application, Pavement Recycling Systems has developed a series of engineering best practices for pavement preservation and recycling. Best practice engineering for roadways means building the required structural section and wearing course at the best price. Today's real world problems also require all of us to reduce energy consumption and greenhouse gases.
PRS combines best engineering with best practice energy use by finding the best way to use in-place materials. Since the turn of the century, we have invested substantial R&D resources seeking new and better ways to improve and use in-situ materials. The result is superior pavement sections at much lower cost.
New Products, New Research.
Using and improving existing technologies like Cold In-place Recycling, Full Depth Reclamation and Soil Stabilization, PRS already has a significant, positive effect on local street budgets.
New technologies we have developed include RAP (reclaimed asphalt pavement) road slurries for pavement preservation; warm-asphalt recycling where 100% of an asphalt roadway is recycled, and cement-treated recycled aggregates as a pavement's load bearing section.
Recouping investments in aging infrastructure.
America needs its roads, but they are aging. Vehicle miles traveled in the U.S. have increased five-fold over the past 50 years to more than 3 trillion vehicle miles a year. Roadways are becoming distressed, carrying heavier loads than originally intended.
Since 2004, unprecedented price increases for steel, cement, asphalt and construction equipment have translated into a 30% plus rise in the cost of street and highway construction. At the same time, federal, state and local governments continue to face shortfalls in funding for roadway construction and maintenance.
PRS pavement preservation and recycling strategies help agencies meet these challenges. We prolong pavement lifecycles' value for their investment in street reconstruction largely by preserving or recouping prior investments.
