Abstract

Strong road infrastructure plays an important role in supporting community mobility, economic growth and regional development. Dirt road pavement is the type of pavement most often used in rural areas or areas with light to moderate traffic. Its advantages include lower costs compared to asphalt pavement as well as ease of construction. However, the main challenge of soil pavements lies in ensuring adequate consistency and stability, as the success of the pavement depends on proper compaction. Compaction of the subgrade road layer is a critical aspect that, if failed, can cause deformation and premature damage to the pavement. One of the tools used to test pavement stability and deflection is the Light Weight Deflectometer (LWD), which provides important data regarding the quality of the subgrade before the pavement is applied.

Abstract

Infrastruktur jalan yang kuat memainkan peran penting dalam mendukung mobilitas masyarakat, pertumbuhan ekonomi, dan pengembangan wilayah. Perkerasan jalan tanah merupakan jenis perkerasan yang paling sering digunakan di daerah pedesaan atau wilayah dengan lalu lintas ringan hingga sedang. Keunggulannya meliputi biaya yang lebih rendah dibandingkan dengan perkerasan aspal serta kemudahan konstruksinya. Namun, tantangan utama perkerasan tanah terletak pada memastikan konsistensi dan stabilitas yang memadai, karena keberhasilan perkerasan bergantung pada pemadatan yang tepat. Pemadatan lapisan jalan tanah dasar merupakan aspek kritis yang, jika gagal, dapat menyebabkan deformasi dan kerusakan dini pada perkerasan. Salah satu alat yang digunakan untuk menguji stabilitas dan lendutan perkerasan adalah Light Weight Deflectometer (LWD), yang memberikan data penting mengenai kualitas tanah dasar sebelum perkerasan diterapkan.

Abstract

Calculating the thickness of the flexible overlay needs to consider several factors, such as traffic load, soil characteristics, existing pavement conditions, and planned changes to the road design. This procedure generally uses recognized pavement design methods, such as the AASHTO 1993 method (Guide for Design of Pavement Structures). This research aims to determine the thickness of the added layer using an asphalt layer on composite roads in accordance with the 1993 AASHTO standards. It is hoped that this method can produce an effective overlay design, extend the life of the pavement, and increase the comfort and safety of road users. The data used in this research includes primary and secondary data. The results of this analysis are to calculate the STA 0 segment, for other STAs use the same method. From the Light Weight Deflectometer (LWD) deflection data, the Subgrade Reaction Modulus (k) value was 473 psi/in, the Concrete Elasticity Modulus (Ec) value was 4,843,105 psi and the Rupture Modulus (Sc') value was 699 psi. The traffic load used is 25.000.000, so the result of calculating the plate thickness to serve future traffic (Df) is 10.79 inches or 27.40 cm and the effective plate thickness value (Deff) is 9.13 inches or 23.30 cm, then the result is the added layer thickness (Dol) is 3.30 inches or 8.39 cm

Abstract

This research analyses the correlation between air temperature, road surface temperature and pavement temperature using the MPU 6050 accelerometer sensor and the Pearson correlation method. Temperature measurements were taken at several predetermined locations, with the data analysed to identify the correlation between the three types of temperature. The analysis showed a very strong correlation between air temperature and road surface temperature, with a correlation coefficient of 0.7845 at night and 0.9663 during the day. Similarly, there is a very strong correlation between road surface temperature and pavement temperature, with a correlation coefficient of 0.8482 at night and 0.9673 during the day. These findings indicate that an increase in road surface temperature leads to an increase in pavement temperature. It was concluded that the correlation method can be used to predict temperatures at other points without invasive direct measurements, thus preventing damage to the road due to destructive measurements. This method is recommended as an alternative in pavement temperature monitoring.

Abstract

In an era of rapid technological and infrastructural development, the quality of roads is critical to ensuring efficient and safe mobility. Composite roads, which consist of a mixture of different types of construction materials, have become an attractive option in road development in various regions. However, to ensure the success of composite roads, structural consistency and performance must be considered. A Light Weight Deflectometer (LWD) is a device used to measure the instability of road layers by applying surface pressure and measuring the resulting deflection. Although the use of LWD is common in the road construction industry, specific research on LWD consistency testing of composite roads is limited. This study investigates and analyzes the consistency of LWD on composite roads to improve the understanding of its performance. The results of the study on composite pavements conducted at three points with 30 trials showed a coefficient of variance of less than 5%. This result indicates very strong data consistency. Based on these consistency values, the LWD is acceptable, but it needs to be correlated with other tools to determine its validity. If the consistency and correlation meet the requirements or are less than 5%, LWD has a good chance of being used in composite pavements.

Abstract

Asphalt is a primary component in road pavement construction. Optimizing the utilization of industrial waste, such as fly ash from coal-fired power plants, is increasingly important as the number of companies using coal as fuel continues to grow. Although fly ash is widely used, applying nano fly ash as an asphalt additive remains limited. This study aims to evaluate the effectiveness of nano fly ash as an additive to improve the characteristics of asphalt. The research follows an experimental method conducted entirely in a laboratory setting. Testing was based on the 2018 Bina Marga Technical Specifications, with procedures aligned to AASHTO, ASTM, and SNI standards to ensure accurate and reliable results. Nano fly ash was added to Pen 60/70 asphalt in variations of 0%, 1%, 2%, and 2.5%. Each asphalt sample underwent parameter tests, including stability, flow, density, and stiffness. Results showed that the 1% addition provided the best outcomes, meeting all specified standards and demonstrating improved asphalt characteristics across multiple parameters. Variations of 2% and 2.5% yielded fewer compliant parameters, suggesting diminishing returns at higher nano fly ash levels. These findings indicate that nano fly ash can be a viable additive for Pen 60/70 asphalt, with a recommended optimal use of 1%. Further studies on economic viability and scalability are suggested to enhance the practical application of this material. Keywords— Pen 60/70 Asphalt, Nano Fly Ash Additive, Road Pavement Improvement, Industrial Waste Utilization
