The Overloading Effect on the Design Life of Road and Thickness of Pavement Layer

Abstract

Solo-Yogyakarta KM 9-15 Road is the national highway, which supports the traffic of goods and services, but many passing goods transport vehicles do not match the allowable load. As a consequently, the damage on the pavement occurred. Therefore, this study aims was to know the effect of overloading on design life and pavement thickness. This study used the method of Binamarga to analyze the effect of pavement thickness caused by overloading. The analysis was carried out by using the formula of design life decreasing with the value of Cumulative Equivalent Standard Axle (CESA) for overloading and standard load. Based on the 2013 Binamarga method, the design life is reduced by about eight years, from the previously determined is 20 years. Moreover, based on the analysis on pavement thickness of 20 years design life for a standard load, it showed that pavement thickness is needed for total surface layer is 100 mm consist of AC WC 40 mm and AC BC 60 mm. In addition, the base course layer is 145 mm (AC Base), and the subbase course layer is 300 mm (LPA Kelas A). At the same time, for overloading, the analysis result showed that it was required the pavement thickness for the surface layer is 100 mm, the base course layer is 180 mm, and the subbase course layer is 300 mm. These results indicate that overloading causes a reduction in the design life of the pavement and an increase in the thickness of the pavement.

Revealing the impact of losses on flexible pavement due to vehicle overloading

“…9, 170-205 mm thickness is obtained to anticipate overloading of vehicles using Arizona local calibration because it is considered to have a freezing index of 0, which is in line with Indonesia [33]. Where the results of this additional layer thickness allow it to be a solution for road administrators when compared to the design of road construction against overloading carried out by [34] because currently, the roads that have been built are more dominant than the construction of new roads, so as a solution for road management, especially vehicle overloading this is beneficial.

Analysis of Remaining Service Life for Flexible Pavement Using Mechanistic-Empirical Methods

“…Figure 3 shows that as the design life increases, the CESA4 value will increase also. The analyze the reduction in design life and the effect of pavement thickness by using the formula of design life decreasing with the value of Cumulative Equivalent Standard Axle (CESA) [23]. Figure 4 depicts the relationship between load repetition and fatigue cracking and rutting.…”
