Recycling saves money and natural resources
Full-depth reclamation uses the materials from the team-deteriorated asphalt pavement, and, with the addition of cement, creates a new stabilized base. A surface consisting of a thin bituminous chip seal, hot–mix asphalt, or concrete completes the parking lot or roadway. The recycled base will be stronger, more uniform, and more moisture resistant than the original base, resulting in a long, low-maintenance life. And most important, recycling costs are normally at least 25% to 50% less than the removal and replacement of the old pavement.
A WISE CHOICE
Conserving Virgin construction materials through recycling with cement makes smart, economic, strategic sense. A century of modern growth and urbanization in America has depleted once plentiful aggregate supplies. Frequently, they either come from distant quarries at a great expense or from local sources offering only marginal quality. Continuing to exhaust these valuable resources to rebuild existing roads only propagates and accelerates the problem.
Additionally, old asphalt and base materials are not recycled, they must be disposed of or stockpiled, increasing transportation costs and utilizing valuable rental space. In some locales, old asphalt can no longer be landfilled. Environmental laws are becoming stricter, thus adding to the next expense of mining new materials and then filling old.
Recycling with cement makes the reconstruction of old roads a largely self-sustaining process. The old “investment” in virgin road materials becomes a one-time cost, which is renewed periodically, through cement stabilization and a new, thin-surface course.
