Abstract

The scarcity of natural materials that meet specifications for road rehabilitation has encouraged the utilization of recycled pavement materials, particularly cement-treated recycled base (CTRB). Despite its widespread use, CTRB is susceptible to shrinkage cracking, which can lead to reflective cracking in the surface layer and reduce pavement service life. This study investigates the performance of CTRB and a modified mixture incorporating emulsified asphalt—designated as IRBCAE (In-place Recycling with Cement and Asphalt Emulsion)—to mitigate shrinkage-induced cracking. Both mixtures were prepared using recycled aggregates containing 5.34% residual asphalt, with a composition of 49% surface course and 51% base course aggregates. Resilient modulus testing was conducted to evaluate mechanical behavior, and pavement structural responses were analyzed using KENPAVE software. The results indicate that IRBCAE exhibits viscoelastic characteristics with superior fatigue cracking resistance, whereas CTRB demonstrates higher stiffness and greater resistance to permanent deformation. In practical application, CTRB requires a thicker asphalt overlay to prevent reflective cracking, while IRBCAE enables the use of a thinner asphalt layer. The differences in structural performance between the two mixtures provide a basis for selecting suitable stabilization methods for recycled base layers.

Abstract

Confined masonry walls are commonly found in non-engineered housings in Indonesia. To better understand their behavior and to find improvement to the current practice, experimental studies have been conducted using full-scale (3m × 3m) wall specimens, which represent simple housing wall panels. In this research, the performance of plastered confined masonry walls in resisting lateral loads was studied experimentally. Three wall specimens were constructed following general construction practice in Indonesia. All specimens were plastered on both sides. Model 1 was constructed without continuous anchorage, Model 2 with two continuous anchorages with 1m spacing, and Model 3 with two continuous anchorages with 0.5m spacing. The specimens were subjected to cyclic in-plane lateral loads. The parameters evaluated were damage pattern and failure mechanism, load capacity, stiffness, ductility, and energy dissipation. The study revealed that adding plaster improved the wall’s lateral capacity. The continuous anchorage shows less significant improvement on plastered walls compared to non-plastered walls, but still increased stiffness, ductility, and energy dissipation. The study verifies that having plaster and continuous anchorage improve structural performance while delaying damage. Analytical study reveals that all models have adequate capacity to resist the design seismic load based on the current code.

Abstract

Floating wind turbines and floating houses are innovative solutions to global challenges such as land scarcity and rising sea levels. This study investigates the dynamic responses of both structures under wave excitation. The floating wind turbine is modeled as a cantilever column with a lumped mass at the top, while the floating house is idealized as a single-story portal frame. Both structures are supported by pontoons, which are represented as beams on elastic foundations using the Winkler foundation theory. Wave loads are modeled based on linear wave theory and Froude-Krylov forces. The analysis is conducted in the time domain using the Finite Element Method and Newmark-Beta integration scheme. The results show that the floating wind turbine experiences a maximum drift of 61.986 mm, heave of 104.310 mm, and pitch of 0.141°, whereas the floating house experiences a maximum drift of 35.587 mm, heave of 60.621 mm, and pitch of 0.408°. The highest internal forces occur in the pontoon section of both structures, indicating that the pontoon plays a significant role in resisting wave loads. This study contributes to a better understanding of the dynamic behavior of floating structures and demonstrates that a simplified 2D modeling approach can be effectively used as an initial step in designing stable and efficient floating systems.
