While only 9% of the 400 million tons of plastic produced annually is recycled, waste plastics are now being used to reinforce asphalt. Tests in Texas showed that a coating made with melted plastic prevented cracking at temperatures above 38°C and increased road resistance by 171%.
In 2025, Texas engineers mixed 4.5 tons of recycled plastic into a highway, replacing part of the bitumen to test how it handles extreme heat
US News: On State Highway 205 in Rockwall, a suburb east of Dallas, engineers paved a 3,500-foot stretch of road using about 4.5 tons of recycled plastic mixed.
Plastic waste reaches the roads: Texas tests the asphalt in which 4.5 tons of waste replaced part of the bitumen
Dodavanje reciklirane plastice u asphalt drastično povećava njegovu čvrstinu i otpornost na paklene vrućine, čime se produžava vijek trajanja puteva i istovremeno rješava problem ogromnog plastičnog otpada.
Early indications suggest that the technique could extend the life of a road by several years. Researchers in Texas are testing a different way to manage plastic waste, converting thousands of pounds of plastic into road construction material. In Rockwall, a suburb of Dallas, about 4.5 tons of recycled plastic were used to build 1,600 meters of road. The plastic was used as part of the asphalt, replacing about 8% to 10% of the traditional petrol…
