Abstract

Roads that have poor surface roughness can cause uncomfortable to road users, traffic accidents, increase dynamic loads on the road surface, thereby accelerating the process of road damage, and damage to vehicles. This research aims to evaluate the stability of road conditions based on the international roughness index (IRI). Evaluation of road stability conditions was carried out on 14 road segments in the city of Yogyakarta, with details of four secondary arterial road segments and 10 secondary collector road segments. Data on road surface roughness (IRI) values were obtained using NAASRA roughness meter which refers to SNI 03-3426-1994. Evaluation of the stability of road conditions is done by comparing the IRI values of the survey results and the limits of IRI values determined by the Directorate General of Highways. The results showed that 14 roads were evaluated, 64% were in moderate condition and 36% were in good condition. Of the 14 roads, the Sisingamangaraja, Lowanu, and Sugeng Jeroni roads have the highest IRI value in a sequence so that the three road segments are prioritized for handling.

Abstract

The Remaining Service Life (RSL) of the pavement can be used to assist in determining the proper timing of maintenance work. This study aims to analyze the value of the remaining service life of flexible pavement based on the prediction of damage that occurs using the MEPDG method and based on the prediction of pavement performance conditions with the Pavement Condition Index (PCI) value. Three roads in D.I. Yogyakarta is used as the object of research, namely the Milir-Sentolo, Pakem-Prambanan, and North-West Arteries. Prediction of the remaining service life of the pavement is calculated based on the prediction of the amount of damage. The types of damage predicted were rutting, alligator cracking, and longitudinal cracking. The pavement response value is obtained from the results of the analysis using the Kenpave program with the modulus of elasticity of the material for each layer as input. The results of the analysis show that the Pakem-Prambanan road segment has the longest remaining service life, both based on the prediction of pavement damage (³ 14th year), and the predicted PCI value (7th year). This is because this section serves the least traffic compared to others
