Concrete is made with renewable resources.
Unlike asphalt pavements that are made with non-renewable petroleum supplies, concrete materials are made from abundant, sustainable resources including water, natural rock and sand, and cement. The predominant raw material for the cement in concrete is limestone, the most abundant mineral on earth.
Concrete can utilize recycled and waste materials.
Ready mix suppliers routinely use fly ash, ground blast furnace slag, and silica fume–all byproducts from power plants, steel mills, and other industrial processes. You can also use recycled aggregates in the concrete mix and reinforcing steel that has a high recycled content.
Concrete saves energy by reflecting light.
One of the greatest overlook characteristics of concrete is that it is naturally brighter and more reflective than asphalt, saving energy by reducing the need for lighting at night. Up to 27% of light falling on a concrete surface will be reflected, compared with as little as 5% of light from asphalt pavements according to the American Concrete Pavement Association. In addition, light colored paving materials help reduce the heat-island effect in urban areas.
Concrete lasts longer.
A properly installed concrete pavement should last for many decades – and at least two or three times longer than an asphalt driveway and requiring far less maintenance. Because concrete pavements don’t need to be replaced or resurfaced as often, fewer raw materials are consumed over the life of the pavement. Concrete can be recycled at the end of its service life.
If your concrete driveway or sidewalk ever needs to be replaced, it can be crushed and recycled at the end of its service life. The material from your recycled driveway is then used as granular fill, as a base for the new pavement, or as aggregate in new concrete. Gary Groh Construction LLC takes all of its concrete to be recycled and reused again as fill. We are committed to recycling not only on the job site but at our shop as well. We recycle all of our plastic bottle containers, oil, and cardboard boxes. We reduce, reuse, recycle. So should we all!
