Plus Anti-skid pavement-1

In a continous effort to improve safety on its highways, the North-South Highway Project (PLUS), today held a media briefing at the Kajang interchange on the anti-skid pavement it has applied in certain areas. Mohammad Fuad Khusairi, chief operating officer of PLUS, said, “we have applied the technology at 10 accident hotspots since 2010 such as the slip roads at Rawang, Bangi, Kajang, Bertam, Ayer Hitam, Yong Peng and others.”

According to Fuad, the application of the pavement has helped reduce accidents in those critical areas by 50%. PLUS has spent RM5.5 million thus far on applying the anti-skid pavement. The pavement increases friction between the pavement and tyre, increasing tyre grip and reduces skidding at bends and corners.

The anti-skid pavement comprises of a layer of anti-skid aggregate that is applied on top of the existing road surface. A layer of resin and silicon carbide is then applied on top of the aggregate to seal it in. Fuad said the coating will last approximately five years before reapplication is required.

The coating is applied overnight, and takes three to four hours to dry before the highway is re-opened to traffic. Fuad said oil spillage from accidents will damage the coating, requiring reapplication.

“Although the coating appears as if it is slippery and oily, it actually increases grip and prevents vehicles from skidding,” said Fuad. In the briefing, Fuad explained that normal roads, without the coating, have a skid resistance value (SRV) of 45. This is increased to above 65 SRV after application of the anti-skid pavement.

The anti-skid pavement originates from Germany, and is widely used in applications such as bridges and airport runways. “PLUS would like to remind highway users that although the anti-skid pavement has a positive impact on highway safety, users should adhere to the speed limits at slip roads. Users are also reminded to ensure their tyres are in good condition at all times,” said Fuad.
