Abstract

Kudus Ring Road Damage Assessment and Alternative Handling Kudus Ring Road construction has planned design life of 10 (ten) years but in reality only 1 (one) is visually seen to have suffered damage in various places and most types of damage is damage alligator cracks and holes in both small and large scale. The intent and purpose of this research is to identify and analyze damage to the Kudus ring roads look like the structure of the surface layer of pavement, base coarse layer, a layer of subgrade / embankment soil, and a layer of native soil, and determine how to handle repairs in accordance with the level and type of damage as well as proposed ring road pavement design Kudus. Stages of research in this thesis was to collect primary data and secondary data to determine the issues raised in the Kudus roundabout. For primary data by performing the following a) The study analyzes the visual field damage in the form of road and test pit (hole test) on the side of the road to determine the structure of the existing road perkaran and analyze each existing pavement layers (such as layer thickness, CBR field, density field, etc.). b) Laboratory study was conducted to determine / analyze the characteristics and properties of each layer of pavement properties (such as soil properties test, CBR test, etc.) As for the secondary data with the collected data and the literature of related agencies such as the Kudus geological data, the data traffic of Kudus ring road and others. The damage in the Kudus ring road is structural damage. Cause of damage of Kudus ring road is circumference decreased carrying capacity due to the occurrence of damage and instability in because each layer of pavement layers have a lot that does not meet specifications, geological conditions are alluvial areas (soft clay) and the traffic that passes through a heavily laden vehicle. Alternative treatment is to use a layer of rigid pavement (rigid pavement) the surface layer of water-resistant and able to withstand the existing traffic load. Rigid pavement is seen as more able to cope with the damage that occurred on Kudus ring road circumference compared with a layer of flexible pavement (flexible pavement). Suggested rigid pavement thickness around 32 cm and during the implementation needs to be watched closely to avoid damage - damage caused by one early in the implementation. This is based on an existing flexible pavement a lot that does not meet specifications.
