Asfalt din sticlă reciclată: orașul american în care drumurile strălucesc în lumina felinarelor

Baltimore is utilizing recycled crushed glass in asphalt mixtures, which can replace traditional aggregates. Properly processed glass has shown good performance in road surfaces, with 10-15% glass content yielding satisfactory results. However, past projects revealed issues with larger glass proportions leading to surface degradation. The Federal Highway Administration recommends specific processing and size guidelines for effective use. Crushed glass can enhance asphalt stability and reduce thermal conductivity, but larger particles may cause slipperiness. The main challenge for wider adoption remains the consistent supply of recycled glass.
