Isn't Asphalt Bad For The Environment
Asphalt does have environmental considerations. Its binder is refined from crude oil, and a worn surface can contribute runoff, so the concern is reasonable. At the same time, asphalt is commonly recycled at the end of its life, and how a pavement is built, maintained, and eventually reused largely determines its environmental impact. A well-built driveway that is maintained over many years is part of that picture.
What is the concern?
Asphalt is made with a binder refined from crude oil, and some people worry about its chemistry, the runoff from its surface, and the energy used to heat the mix. These questions deserve direct answers. A balanced view looks at how the material performs over its whole life, not only what goes into it at the start.
Recycling is common practice
When asphalt reaches the end of its useful life, it can usually be milled, which means the top layer is ground off with a milling machine. The removed material, often called reclaimed asphalt pavement, can be crushed and reused in new asphalt mixes or as base material, depending on the project and the specifications. Recycling milled asphalt is common practice in the paving industry.
Runoff and water quality
Water that flows across any paved surface can carry oil, grit, and other materials toward storm drains and nearby streams. Well-maintained pavement, prompt repair of worn areas, and proper drainage design all help reduce that runoff. Sealcoating also helps protect the surface, and the sealer is chosen for each job.
Sealer choices
Some property owners ask about sealers. Coal tar and asphalt emulsion sealers are both used, and each has tradeoffs that depend on the site and the goals for the surface. The choice for each job is explained in the written estimate, so ask your estimator about the options before deciding.
Energy, maintenance, and lifespan
Hot-mix asphalt is produced at elevated temperatures, which uses energy. Pavement that lasts longer needs fewer repairs and less new material over time. That is why sound base preparation, timely crack repair, and regular maintenance matter for the environment as well as for the owner's budget.
How asphalt compares with other surfaces
Every paving material has tradeoffs. Concrete requires cement, which is energy intensive to produce. Gravel surfaces need periodic replenishment and can wash away with heavy rain. Asphalt offers recyclability and a smooth, durable surface. The best choice depends on how the area will be used, the site conditions, and how the surface will be maintained.
What property owners can do
- Repair cracks early so water does not reach the base.
- Keep drainage moving away from pavement edges.
- Ask about sealer options and how each one is applied.
- Plan routine maintenance so the surface lasts longer.
Small, steady steps usually do more good than waiting for a large repair.
Frequently asked questions
Is recycled asphalt as good as new asphalt?
Reclaimed material is used in many mixes and base layers when the specifications allow it. The right mix depends on the project, the quality of the material, and the engineering requirements, so the decision is made for each job rather than assumed.
Can old asphalt be recycled on my property?
Often it can. Milled material may be reused on site or taken to a recycling facility, depending on its condition and the project plan. Ask your estimator how removal and reuse would work for your project.
Does sealcoating harm the environment?
Sealcoat products vary, and the choice between coal tar and asphalt emulsion is worth discussing with your estimator. Each option has tradeoffs, and the written estimate states which sealer is recommended and why.
