Asphalt is dirtier than it looks.
But the world’s most polluted place is the United States, according to a new report that ranks the dirtiest places on the globe by number of asphalt repairs and the percentage of asphalt pavements that are being replaced.
The report, by the nonprofit environmental group Environmental Integrity, ranked the dirtest places on Earth according to how much asphalt is being removed, the number of pavement repairs that have been completed and the amount of pavement that has been replaced.
In the United Kingdom, the dirtier the place, the more asphalt was removed in its most recent year.
The U.S. was the dirtliest place on Earth, with nearly 20 percent of the asphalt in its nation being removed.
In New Zealand, which is the most polluted country on Earth and has the highest rate of pavement removal in the world, there are more than 6,000 miles of pavement, according the Environmental Integrity report.
The United Kingdom has more asphalt than any other country in the report, with 4,000 kilometres.
The country has a high rate of asphalt removal, with about 40 percent of its roads in use.
The rest of the country has less than 4 percent.
The number of miles of asphalt in use in the United Sates, New Zealand and the U.K. increased by more than 15 percent in the last decade, according EPA data.
The agency reported that in 2010, U. S. roadways averaged about 4,300 miles of surface pavement per year, down from more than 7,000 in 2000.
The overall number of surface miles in use decreased by about 5 percent, while the percentage that was paved or paved-over decreased by 9 percent.
In 2010, there were 8.5 million miles of paved roads in the U, compared to 11.2 million in 1999, according U.N. figures.
But U.s. road miles are declining more quickly than in other countries, according a 2009 study by the Pew Charitable Trusts.
The Pew report said that the rate of road construction has fallen in recent years.
The rate of roadway construction in the country decreased from 10.6 million miles in 2010 to 6.7 million in 2020, according data compiled by the U-M Transportation Research Institute.
The study said that a majority of Americans drive at least some of the time, but only about half drive for the rest of their lives.
