Abstract

Perencanaan perkerasan jalan yang andal penting untuk menjamin umur rencana dan kinerja struktural, terutama pada ruas jalan dengan volume lalu lintas tinggi seperti pada rencana Jalan Tol Gilimanuk–Mengwi. Penelitian ini memiliki urgensi untuk membandingkan metode desain perkerasan kaku yang mengusung prinsip empiris dan mekanistik empiris terhadap kondisi lapangan di Indonesia, yang memiliki karakteristik iklim tropis dengan curah hujan tinggi serta tanah dasar bervariasi. Penelitian ini bertujuan membandingkan hasil tebal perkerasan kaku dengan metode AASHTO 1993, Pd T–14–2003, dan Manual Desain Perkerasan 2024 (MDP 2024). Metode penelitian dilakukan menggunakan pedoman desain perencanaan pada tebal slab beton, yaitu AASHTO 1993, Pd T–14–2003, dan MDP 2024. Hasil analisis menunjukkan metode AASHTO 1993 menghasilkan tebal slab 30,00 cm dengan nilai W18 sebesar 31.363.966 ESA, menunjukkan efisiensi struktural tinggi. Metode Pd T–14–2003 memperlihatkan hasil analisis kelelahan dan erosi dengan nilai persentase kerusakan di bawah 100%, menandakan desain yang aman secara struktural. Sementara metode MDP 2024 menghasilkan nilai fatigue 0% dan erosi 92,77%, menandakan ketahanan tinggi terhadap beban berulang dan potensi erosi tanah dasar. Kesimpulannya, metode MDP 2024 paling representatif dan adaptif terhadap kondisi lalu lintas serta lingkungan di Indonesia. Penelitian ini berkontribusi dalam memberikan dasar ilmiah untuk pemilihan metode desain perkerasan kaku dalam konsep empiris maupun mekanistik empiris.

Abstract

Cold Mix Asphalt Emulsion (CMAE) has the potential to serve as an environmentally friendly, efficient, and accessible alternative for road construction, as it eliminates the need for heating during production and can be compacted at low temperatures. One of the key factors affecting CMAE performance is the aggregate gradation used in the mixture. This study aims to analyze the effects of aggregate gradation on the volumetric characteristics, mechanical properties, and durability of CMAE. Laboratory experiments were conducted using several aggregate gradation types. The results indicate that the middle-limit gradation (G. L2) produced the highest dry density, while the lowest air void content was found in gradation G. L1. The mechanical properties, including soaked stability and Indirect Tensile Strength (ITS), were positively correlated with dry density, as they are influenced by aggregate structure, the asphalt emulsion content, and its asphalt adhesion quality. CMAE durability measured through moisture susceptibility (TSR) and mass loss (Cantabro loss test) was affected by the gradation type, asphalt–aggregate bonding, and water content in the mixture. Overall, aggregate gradation plays a critical role in determining CMAE performance. Notably, optimal performance is achieved when the mixture has fully lost its moisture, allowing for maximum asphalt binding efficiency. These findings highlight the importance of selecting appropriate aggregate gradation in CMAE design to enhance performance outcomes.
