Summary: The study focuses on the impact of reclaimed asphalt pavement materials on air quality and resource conservation during sustainable cold-recycling. The investigation analyzes the adhesion characteristics of asphalt-aggregate interface in different cold recycled asphalt mixtures using atomic force microscopy. Results show that the addition of cement enhances the roughness and inclination in the interface regions, while the mixing water amount has the most significant effect. The adhesion force, DMT modulus, and dissipated energy increase with the addition of cement, indicating improved microscale mechanical properties of cold recycled asphalt mixtures.

Summary: This study investigates the use of waterborne epoxy resin (WER) and styrene butadiene styrene (SBS) composite modified emulsified asphalt sealant (WER-SBS-EA) for crack sealing. The results show that WER increases the shear strength of the sealant and the optimal WER to SBS-EA ratio is 2:3. WER-SBS-EA exhibits hydrophobic properties and has higher surface energy and work of adhesion compared to SBS-EA. Additionally, the bonding strength of WER-SBS-EA remains higher even after aging, making it a suitable preventive maintenance material for extending the service life of asphalt pavements.

Summary: Ice protection techniques in aerospace and wind energy applications have limitations in terms of cost and convenience. This review focuses on the use of passive icephobic coatings, specifically examining the role of surface roughness in anti-icing and de-icing performance. The interdependence of surface roughness with other icephobicity strategies, such as superhydrophobicity and elastomeric surfaces, is discussed. Furthermore, the sensitivity of de-icing evaluation methods to surface roughness is explored.

The combined PVDF-SPTFE coating shows superior electrochemical characteristics, hydrophobicity, and icephobic properties. The decrease in ice adhesion strength after treatment with PVDF-SPTFE is significant, making it a promising solution for anti-icing applications.

Summary: Bentonite is commonly used as the drilling fluid for cast-in-situ bored pile constructions. It has been observed that the formation of bentonite filter cake significantly reduces the shaft resistance capacity of piles in sedimentary bed rocks. However, its impact on crystalline metamorphic rocks is relatively insignificant. The lack of reliable experimental data has resulted in conservative pile designs being used, but recent studies conducted in Sri Lanka suggest that unnecessary conservatism can be avoided.

Summary: Structural adhesive bonding has advantages over welding and riveting. However, creep is an important long-term phenomenon that needs to be considered. Experimental investigations at the scale of the adhesive layer are necessary. The Arcan test method was chosen for its advantages and a mechanical testing machine was developed to study the creep behavior of adhesive layers.

Summary: A method for predicting rutting in semi-rigid pavement structures was proposed using accelerated loading tests and finite element analysis. Dynamic modulus and creep tests were conducted on three pavement materials to obtain a prediction equation, which was then validated using the falling weight deflectometer test and back-calculation modulus. The results showed that rutting deformation varied under different conditions, highlighting the need for maintenance and repair of pavement structures.

Summary: This study investigates the mechanical behaviors of hydraulic asphalt concrete (HAC) under combined compressive-shear stress at different temperatures and normal compressive stresses. The results show that the combination of normal compressive stress and temperature affects the peak shear stress and correlated shear strain. An increase in normal compressive stress leads to the emergence of horizontal cracks and an amplification of deformation at elevated temperatures. The peak shear stress progressively increases with an increase in normal compressive stress, but decreases with an increase in temperature. The study also establishes three modified compressive-shear failure criteria for HAC at different temperatures.
