Full text not available from this repository.Abstract
Road pavement condition deteriorates due to traffic loading and environment and to maintain the pavement in a satisfactory condition, various maintenance treatments are required periodically. When using the life-cycle approach to maintenance, prediction of pavement condition over its design life is needed and both the Bina Marga and HDM-IV models have this capability. Bina Marga predicts the deterioration of pavement condition in term of reduction in Present Serviceability Index (PSI). The variables that are used in the prediction are cumulative traffic loading (N), Initial PSI, SUbgrade Support (SSG), Regional Factor (RF) and Structural Number (SN). The HDM-IV model predicts the deterioration of pavement condition in term of individual components of the PSI value such as Cracking, Potholing, Ravelling, Rut depth and Roughness. The variables used and the calculations are more complex because the progress of each type of deterioration is predicted separately and each type of deterioration influences the other in the calculations. The International Roughness Index (IRI) used in the HDM-IV models have been correlated with PSI. Comparing prediction based on PSI value, these are similar if the structural number is low i.e. SN = 8. At higher structural number value (SN = 12 and 16), there are significant differences between the predictions; the HDM-IV model predicts a more rapid deterioration of pavement condition. For using the pavement condition prediction in the life-cycle approach to maintenance, HDM-IV is more realistic. The model predicts the progress of various types.. of deterioration and can quantify the magnitude of deterioration year by year over the pavement design life. On the other hand, Bina Marga only predicts the PSI value, so the magnitude of individual types of deterioration cannot be determined from the model. In Summary, the Bina Marga model is simpler and possibly more practical but it only considers the global condition. HDM-IV Model is more complex and more difficult to operate but provides a more detailed prediction of condition.
