PREDIKSI UMUR RENCANA FLEXIBLE PAVEMENT MENGGUNAKAN METODE HDM III

Abstract

Outputs that need to be known in designing AC WC flexible pavement construction is how long the infrastructurecan provide services based on the quality and accumulation of the available load, in other word during the service periodit is expected that there will be no significant damage to the construction. According to the World Bank terminology thatthe "pavement age" is the service life up to the initiation of a fine crack on the pavement surface, while "pavement life" isthe service period at the time of occuration of 50% cracks. The modulus of elasticity of asphalt mixture, value of each ofpavement layer strength coofficient material, bearing capacity of the subgrade and design of annual accumulation data of8.16 tons standard axle load is essential to predict pavement age and pavement life of construction with HDM III methodprovided by the World Bank. The purpose of this research is to analyze the effect of traffic accumulation, effectivegravity weight of aggregate fraction mixture (Gse) and mixed asphalt content to the pavement age and pavement life offlexible pavement construction. The largest and smallest of design life, both in pavement age and in pavement life, occurin Gse and asphalt content level of 2,738 and 6,5% respectively. The longest and shortest time of achievement of thepavement age are 4.64 and 4.10 years respectively. While the longest and shortest period of achievement pavement liferespectively 10.64 and 10.10 years.
