Abstract

Assessing road surface quality is essential for maintaining and ensuring the safety of transportation infrastructure. This study evaluates the effectiveness of Mobile Laser Scanning (MLS) using the Leica Pegasus TRK 700 Evo in comparison to the conventional Dipstick method for measuring the International Roughness Index (IRI) on road surfaces. IRI data were collected from five sample locations, with observed differences between the two methods ranging from 0.02 m/km to 1.00 m/km and an average deviation of 0.19 m/km. The results suggest a high degree of compatibility between the IRI values generated by both methods, indicating that MLS can serve as a reliable alternative for road condition surveys. The Leica Pegasus TRK 700 Evo demonstrated operational efficiency, capable of surveying 40 to 100 kilometers of road per day under typical field constraints, such as equipment setup and GNSS base station relocation every 15 kilometers. Data processing required approximately four hours for every hour of field measurement. A field deployment scenario was developed, detailing the necessary resources, including a survey vehicle equipped with the MLS unit (staffed by a driver, operator, and section owner), a support vehicle for high IRI zones, a GNSS base station transport vehicle, and a two-person data processing team. The findings demonstrate that MLS technology is a practical and efficient tool for road condition assessment and offers a flexible, reliable alternative to traditional survey techniques in managing transportation infrastructure. Keywords: International Roughness Index (IRI), Mobile Laser Scanning (MLS), point cloud, road condition, road assessment.

Abstract

The Lampung Provincial Road and Construction Agency reported in 2022 that approximately 391.985 km or 23.05% of road infrastructure was damaged. The use of hot mix asphalt (HMA) for road repairs requires high production temperatures, resulting in increased energy consumption, fuel costs, and GHG emissions. Therefore, the environmental impact of road paving should not be ignored. Additives are added to the mixture to lower the mixing temperature, resulting in a mixture known as warm mix asphalt (WMA). In analyzing the potential for environmental impact savings, LCA was used. Inventory data was obtained from previous research literature studies. LCA was conducted based on a gate-to-gate approach that only covered the mixing process at the asphalt mixing plant (AMP). This study aims to determine the potential for energy reduction, fuel consumption savings, GHG reduction, and total cost savings in the alternative use of WMA in provincial road repairs in Lampung Province. Five types of WMA alternatives were considered, namely WMA with Asphamin, Advera, LEA, Sasobit, and Asphaltan additives. The results of the study show that WMA can reduce the mixing temperature and provide energy savings of between 3.15% and 13.65%. From an environmental perspective, WMA also reduces GHG emissions, with a reduction potential of up to 5.00 kgCO₂ per ton of mixture, equivalent to 13.22% compared to HMA. Economically, the use of WMA provides potential production cost savings ranging from 3.05% to 13.22%. Among the five types of additives tested (Asphamin, Advera, LEA, Sasobit, and Asphaltan), the LEA additive proved to be the most environmentally friendly alternative while also providing the greatest energy and cost savings.

Abstract

Toll roads can play a vital role in supporting mobility, logistics, and regional economic growth. However, issues such as congestion, declining road quality, and limited real-time information systems often hinder service performance. This study aims to update the Toll Road Service Quality (TRSQ) model by integrating artificial intelligence (AI)-based technological innovations as a mediating variable to enhance excellent toll road services. Using a quantitative explanatory approach, data were collected from 480 users of the Pemalang–Batang Toll Road via a questionnaire survey. Data analysis employed SmartPLS to test causal relationships among TRSQ variables, which include information, accessibility, reliability, mobility, safety and security, rest areas, and responsiveness. Results show that all TRSQ variables significantly influence service excellence, both directly and through technology as a mediator. Priority indicators identified include toll gate queue length, availability of road markings and information boards, traffic flow, real-time traffic updates, and service comfort. The study highlights the urgency of applying AI-based intelligent transportation systems—such as innovative CCTV, remote sensors, and automated information management—to optimise toll road performance, improve user satisfaction, and strengthen sustainable transport services.

Abstract

Permanent deformation is a common type of distress that occurs on pavement surfaces due to the inability of the pavement structure to withstand repeated traffic loading. This type of damage leads to irreversible changes in the pavement surface, such as rutting and surface irregularities, which can compromise both driving comfort and road safety. To address this issue, innovative surface treatment solutions are needed to enhance pavement performance and service life. One such solution is SteelGuard, a polymer-modified asphalt surface coating specifically designed to repair minor surface damage. SteelGuard can be applied using spray techniques or brushed directly onto existing pavement surfaces. The research method involved two combinations of test specimens, namely asphalt concrete wearing course (AC-WC) with and without SteelGuard coating. To analyze the effect of the SteelGuard layer on permanent deformation resistance, tests were conducted using a Hamburg Wheel Tracking (HWT) under wet conditions at two temperatures, 28°C and 45°C. The analysis compared wheel passes, rut depth, Stripping Inflection Point (SIP), Number of Passes to Failure (Nf), and performance behavior during creep and stripping conditions between the two specimen combinations. The experimental results indicate that AC-WC mixtures treated with a SteelGuard coating exhibit improved resistance to permanent deformation. This improvement is evidenced by a reduction in rut depth and enhancements in other performance parameters. Based on these findings, SteelGuard is considered effective in improving the durability and functional performance of pavement surfaces, thereby contributing to longer service life and improved roadway conditions for users.

Abstract

Roads are one of the key infrastructures supporting public mobility. However, road conditions in Indonesia still face various issues, one of which is the frequent occurrence of road damage even before reaching the planned service life. This damage is generally caused by the insufficient stability of asphalt mixtures, which prevents pavement layers from optimally withstanding traffic loads. One type of asphalt mixture that can address this issue is AC-Base, which functions as a supporting layer beneath the surface layer and transfers traffic loads to the subgrade. Therefore, additive materials are needed to improve the stability and durability of the AC-Base mixture. One of the additives used in this study is LDPE plastic pellets, as previous research has shown that LDPE can improve the properties of asphalt mixtures, particularly stability. However, further research is required regarding the use of LDPE plastic pellets to acknowledge the effect of the use of Low-Density Polyethylene (LDPE) plastic pellets on the characteristics of an AC-Base mixture, and to obtain the LDPE optimum content with various content levels, namely 2%, 4%, 6%, and 8% by weight of asphalt. Based on the experimental results, the LDPE plastic pellet content that met the specified criteria was 2%. The comparison between the control AC-Base mixture and the modified AC-Base mixture with 2% LDPE pellets and AC-Base mixture modified with LDPE plastic pellets on the optimum content of asphalt at 4,5% showed an increase in density from 2.33 gr/cm³ to 2.35 gr/cm³ and residual stability from 90.24% to 91.08%. However, several other parameters decreased slightly: VIM from 3.18% to 3.16%, VMA from 14.13% to 13.56%, VFB from 83.49% to 82.15%, and stability from 1856.33 kg to 1839.34 kg. This research contributes to the development of more sustainable pavement material by utilising polymer waste for asphalt mixture engineering.

Abstract

Single Lane Free Flow (SLFF), known as “Let It Flo,” is a contactless toll payment system based on RFID technology developed by PT Jasamarga to reduce transaction time and queuing at toll gates. However, its implementation has not been fully effective due to low user adoption. This study aims to identify the implementation of SLFF, analyze vehicle flow, service time, service level, and delay time between the E-Toll and SLFF systems, as well as evaluate user perceptions toward the system. The analysis applies queuing theory using vehicle survey data collected at the Bekasi Timur 2 Toll Gate on January 13, 16, and 18, 2025, and questionnaires distributed to toll road users. The results show that SLFF is only used by four-wheeled light vehicles with a low adoption rate of two vehicles per hour compared to 343 vehicles per hour for E-Toll. Nevertheless, SLFF can reduce delay time by 0.6 seconds per vehicle and increase service capacity with a projected result of 6,000 vehicles per hour, significantly higher than the E-Toll system’s capacity of 957 vehicles per hour. The system eliminates queues and reduces congestion with a service intensity below one (ρ < 1), while users report improved safety and comfort due to non-stop and contactless transactions. The main challenges include limited infrastructure, restricted gate availability, ongoing application development, and limited technological information on the SLFF/Flo system. Therefore, infrastructure expansion, application improvement, and government support are essential to accelerate adoption and enhance the performance of the toll system in Indonesia.
