Development Precast and Prestressed Concrete Rigid Pavement System in Indonesia

Abstract

Roadway pavements are important parts of transportation system and thus should be adequately strong and durable. Unfortunately, many pavements constructed in Indonesia fail to reach their design service life. Among major factors contributed to early damages to the pavements in Indonesia are unfulfilled specified pavement construction specifications, traffic overload and poor support condition. As an attempt to produce better pavement system and as part of an accelerated infrastructure program in Indonesia, new precast pavement system using unbonded posttensioned technology that has characteristic of self-centering has recently been developed. This self-centering concrete pavement is expected to reduce the impact of overload and be able to overcome imperfect subbase, subgrade and poor soil condition. The theoretical and experimental development programs of the new concrete rigid pavement system will be described in this paper. The developed pavement system is then implemented to see the effectiveness construction procedures and later on tested using Falling Weight Deflectometer (FWD) method to evaluate its structural performance.
