Abstract

Aggregates from Sampang are still rarely used in flexible pavement. Therefore, this research is to identify the effects of coarse aggregate and soft aggregate from Sampang – Madura, to recognize their performance in the HRS – WC mixture. It adopted Bina Marga General Standards 2010, Division 6 (Revision 3) for HRS – WC mixture, by testing the physical characteristic of coarse aggregate and soft aggregate from Sampang (in terms of specific gravity and absorption, coarse aggregate wear and tear, and sieve passing Nr. 200) and Marshall Characteristic Testing with asphalt content variables of 6%, 6,5%, 7%, 7,5%, and 8% of the total mixture, each with 3 tested objects. With reference to the physical aggregate characteristic, it was found that the coarse aggregate satisfied the specification standard. On the other hand, the value of the specific gravity of the soft aggregate was still lower than the specification standard, i.e., 2,25 gram/cm2, while the minimum standard was 2,5 gram/cm3. It definitely affected the performance of the HRS – WC mixture. As the volume of the mixture was larger and left a larger cavity in the mixture, it required larger content of asphalt in order to generate a mixture qualifying the Bina Marga General Standards 2010, Division 6 (Revision 3). Based on the results of Marshall Test Characteristic Testing, it was found that the optimum content of asphalt was 8% of the total mixture.

Abstract

The roads hold a vital role in the transportation system in the Province of Papua, especially in the Jayapura area. However, real road conditions often experience a decrease in performance (damage) due to construction failures or deviant utilization. On Koti Road in Jayapura, sometimes vehicles passing it do not match the maximum permissible load. Consequently, excessive loading on the pavement can directly affect the design life of a road section. Therefore, this study aims to analyze the percentages of actual overload on each vehicle class, the increase in the cumulative VDF value, and the decrease in the design life on Koti Road, Jayapura. The research results indicated that the actual overload on Koti Road, Jayapura, obtained 81.06% for group 6a, 43.13% for group 6b, and 40.42% for group 7a. According to the Bina Marga method (1987), the cumulative VDF value increased by 133.8% due to actual excessive load in the field, while based on the NAASRA method (2004), it was 121.2%. In terms of the actual overload effects, the design life decreased by 9,273 years, or 46,365%, from the 20-year design life using the Bina Marga (1987) method, while based on the NAASRA (2004) method, the decrease in design life was 8.7898 years, or 43.949%, from the 20-year life plan.
