Reviewing Quality of Roads

44 Mr Muhamad Faisal Bin Abdul Manap asked the Minister for Transport what processes are in place to review the quality of roads, such as those with potholes and those affected by maintenance shortcomings.

Mr Khaw Boon Wan: The Land Transport Authority (LTA) maintains more than 100 kilometres (km) of expressways, more than 700 km of arterial roads, and more than 2,000 km of minor roads in Singapore. LTA conducts inspections regularly to ensure their serviceability, looking out for not only potholes, but also defects in lane markings, signs, kerbs and so on. The frequency of the inspections ranges from once a week for expressways to once every two weeks for major roads to once every eight weeks for minor roads. Defects, such as potholes, are typically repaired within 24 hours upon discovery. Members of the public who wish to provide feedback on road matters can do so by calling the LTA Hotline.

LTA also takes additional measures to reduce the frequency of the occurrence of potholes, ranging from patching of localised road sections to resurfacing of entire stretches of roads. LTA is also studying the feasibility of using asphalt preserver and asphalt mix additives to prevent the formation of potholes.
