This article reports that the Land Transport Authority in Singapore is conducting trials to assess the feasibility of using greener road surfacing materials that incorporate recycled plastic waste. Various field tests are being carried out until the first quarter of 2024 to measure factors such as noise reduction, heat absorption, and road roughness. The trials are part of the government's drive for transport sustainability, and if the new mixes are found to be acceptable, they may be used on selected expressways and roads. The trials involve two asphalt mixes that have plastic waste in them, and they are targeted at different road applications. The article also notes that LTA has changed road construction specifications since 2010 to allow the use of recycled waste materials, and asphalt mixes incorporating recycled plastic waste have been in use overseas since the early 2000s.
