Performance of pavement preservation with ralumac micro surfacing atlatar highway

Abstract

Maintaining pavementto desired level of serviceability as requiredby Malaysian Highway Authority (MHA) give immense pressure to highways operators.Pavement distress such as roughness, rutting and cracking are common problems that occur after the highway has been operational. Pavement preservation has been sought as a potential alternative for managingallthe pavement distress. This paper evaluates the performance of pavement preservation withRalumac Micro surfacing for slow lane and fast lane fromKM23.70 to KM24.10 Eastboundat LATAR highway.The evaluation comprises of International Roughness Index (IRI), texture depth and skid resistance.The result revealed that micro surfacing treatment has significant improvement on roughness, rutting, and skid resistance even after 36 monthsoperational.The performance of Ralumac Micro surfacing at slow lane is slightly lowerthan Ralumac Micro surfacing at fast lane as it affected by heavy vehicles.
