Abstract

Toll roads are one of the infrastructure development targets in Indonesia to speed up traffic and vehicle travel times. This paper analyzes the flexible pavement structure of the Yogyakarta-Bawen Toll Road. It predicts damage and residual values using elastic and viscoelastic approaches based on MDPJ Bina Marga 2017 using the KENPAVE Program. The recommended design alternative is pavement with a layer of AC-WC 40 mm, AC-BC 60 mm, Base AC 180 mm, and LPA 300 mm. This alternative is predicted to be able to serve load repetitions in the elastic approach of 432,857,828 ESAL until fatigue cracking occurs, 215,176,089 ESAL until rutting occurs, and 136,575,580 ESAL until permanent deformation occurs. Analysis using the viscoelastic approach can provide load repetitions of 153,304,378 ESAL until fatigue cracking occurs, 47,014,109 ESAL until rutting occurs, and 71,859,938 ESAL until permanent deformation occurs. Based on the elastic approach, the pavement's service life is 33 years, with initial damage in the form of permanent deformation. In comparison, the viscoelastic approach has a service life of 22.7 years, with initial damage in the form of rutting.

Abstract

The Stone Matrix Asphalt (SMA) concrete mixture generally consists of aggregates, fillers, and additives. Stone dust filler has become a scarce component in the composition of the mix. One alternative filler that can be used is geothermal waste, which contributes to environmental pollution reduction and enhances its utility. This research investigates the influence of geothermal waste content as a substitute filler on the characteristics of Stone Matrix Asphalt (SMA) mixtures. The laboratory research follows the SNI 8129:2015, examining aggregate, filler, and asphalt materials. Subsequently, test specimens are fabricated to determine the optimum asphalt content (OAC). The OAC produces test specimens for Marshall, VCA, IRS, ITS, TSR, CL, and AFD tests. These tests are conducted at each geothermal waste filler substitution level, ranging from 0%, 10%, 20%, 30%, to 40%. The analysis results indicate that using geothermal waste as a filler in SMA mixtures performs optimally at a 40% substitution level. Increasing the substitution level enhances VFWA and density while decreasing VITM and VMA, as well as flow values. The SMA mixture achieves good stone-on-stone contact, demonstrated by the VCA value. As IRS and TSR indicate, geothermal waste improves stability and indirect tensile strength, enhancing the mixture's durability. Geothermal waste enhances the overall integration and homogeneity of the mix, making it resistant to plastic deformation and high temperatures, as observed in CL results.

Abstract

The Solo-Yogyakarta-NYIA Kulon Progo Toll Road is one of Proyek Strategis Nasional (PSN) that has an important role in the smooth movement of traffic. The infrastructure development process must be carefully considered, especially at the planning stage. This paper analyzes the design of rigid pavement planning using MDPJ 2017 and MDPJ 2024 to determine the difference in design results and can be the best alternative design proposal so that it can provide a reference for pavement performance performance. In addition, an empirical mechanistic analysis was conducted using KENSLAB in the KENPAVE program. The program outputs stress, deflection, and service life prediction. The analysis results show that MDPJ 2017 and MPDJ 2024 with JSKN value of 125,538,693,248 have the same rigid pavement thickness value of 305 mm and with KENSLAB analysis, a service life of 1000 years is obtained. MDPJ 2017 and MPDJ 2024 do not produce significant differences, there are only differences in the tie bar spacing and dowel diameter. The different tie bar spacing and dowel diameters have little effect on the value difference in the KENPAVE output. However, the design with MDPJ 2024 has a slightly higher value than MDPJ 2017. Thus, alternative designs are needed to make the pavement performance more effective and efficient, including 200 mm, 185 mm, and 180 mm thick. From several alternative pavement designs, it is concluded that the design that produces the most optimal performance is alternative 3 with a layer arrangement of 180 mm thick slab, 100 mm LMC, and 150 mm LPA with a predicted service life of 48.2 years.
