Analysis of Road Improvement (Overlay) on Road Damage on the West Silver Dorang Fish Road Section Surabaya (STA0+000-STA0+470)

Abstract

Jalan Ikan Dorang Perak Barat Surabaya is categorized as a class I road, which is an arterial road with flexible pavement that is daily traversed by motorized vehicles including cargo vehicles with a width size not exceeding 2,500 mm, a length size not exceeding 18,000 mm and a permitted heaviest axis load of 11 tons, and there is a lot of road damage such as alligator cracks, local cracks, peeling, subsidence, longitudinal cracks, and holes. These conditions reduce the functional value of the road and require maintenance of the road to be very important. This research discusses the handling of road damage with the overlay method which is considered faster, and more efficient, and gets a more optimal result. This is because the method is widely used for planning the thickness of pavement in Indonesia. The results of this study are known on the road section, the traffic conditions are quite heavy, and the level of functional conditions is Heavy Damaged, so it is necessary to increase the road (overlay) as high as 4.5 cm with the type of pavement (AC-WC).
