It’s good news for the environment and the asphalt industry in general.
Last year, an epic 79 million tons of asphalt material was reused by the construction business. The asphalt products being recycled comprise of components such as blast furnace slag and tire rubber.
And across the United States the statistics for recycling this versatile paving material are encouraging.
In fact, studies done in 2017 prove that asphalt is by far the most consistently recycled material.
Last year, 99 percent of all old roads which were dug up, found themselves being reused. This figure also includes the hundreds of square miles of asphalt paving, which have been either newly resurfaced, or completely re-laid.
By using Reclaimed Asphalt Paving Material (RAP) and Recycled Asphalt Road Shingles (RAS) $2.2 billion dollars has been saved in the purchase of new materials.
Reclaimed Asphalt Paving Material (RAP) accounted for 76.2 million tons of product that was recycled and Recycled Asphalt Road Shingles (RAS) made up 950000 tons last year.
On top of this, almost 4 million tons (3.9 million) of both RAP and RAS were used in cold mix asphalt. This has been used for both paving and road building and has also found its way into the components of aggregate.
Most of the recycled asphalt was turned into new paving structure and is what we are walking and driving on today.
Furthermore, over a hundred million tons (103.5 million) has been set aside by the industry, of both RAP and RAS, for use in new construction projects.
By recycling this product it has been estimated that 50 million cubic yards were saved in the nation’s landfill sites.
WARM MIX ASPHALT
Asphalt has long been one of the most recycled products there is.
Not only is this set to continue, but there are also other ways in which asphalt is becoming more environmentally friendly.
The use of warm mix asphalt has also increased rapidly over the last few years.
Since the year 2009, the National Asphalt Pavement Association has been studying asphalt production methods used in construction, by the asphalt paving industry.
They have recorded the usage of the various types of material, as used by asphalt paving companies, up and down the land.
One thing NAPA has been looking keenly at is the use of warm mix asphalt.
Between 2009 and 2010, the use of this form of asphalt increased by 148 percent. This is something which is continuing today.
Last year, its use was up to well over a third of all new road construction across the country.
In fact, it accounts for 39 percent of road building.
This translates into an impressive 147.4 million tons of warm mix asphalt being used on the nation’s roads in 2017.
Warm mix asphalt is better than the traditional hot mix asphalt for the planet. This is because it takes less fuel and energy to produce.
Additionally, there are less gases and fumes associated with its cooling process. It also compacts better and more easily at a low temperature.
Its elevated use marks an increase of 777 percent in under ten years!
Although some professional asphalt paving contractors do utilize the benefits that warm mix asphalt has to offer, it has been mainly state departments who have been responsible for the uptick in its usage.
Since it is the DOTS (state departments of transport) who oversee the building of highways and roads, they are clearly likely to be the ones purchasing large quantities of asphalt.
The NAPA chairman, Craig Parker says this because the road commissioners and bodies who own the highways can see the benefit that warm mix asphalt brings to the environment.
