Typical West Java Road Surface Power Spectral Density 830914

One of the factor which determine vehicle ride quality is the waviness of the road surface. A series of power spectral density measurements has been done on several road types in West Java, that is Macadam, Nacas, Coldmix Buton Asphalt and Hotmix Buton Asphalt. The measurement were carried out by means of fifth wheel and the data were digitally analysed using Spectrum Analyser and Desktop Computer, The results would be very useful for the development of vehicle design, and for the construction of the road itself.
