Summary: This study evaluates the effects of adding 1% Portland cement or 1% hydrated lime on the compactability and volumetric properties of 100% reclaimed asphalt pavement and bitumen emulsion Cold Recycled Mixtures (CRM). Dynamic triaxial tests were conducted to determine the influence of these active filler additions on the resilient modulus (Mr) of the mixtures. The results showed increased Mr values at lower temperatures and reduced stress dependencies for all mixtures, with cement addition improving compactability and hydrated lime addition resulting in greater increases in Mr and reduced stress dependencies. The results were analyzed using the Stress-Temperature Superposition Principle (STSP) for simpler and more straightforward analysis.

Summary: This study evaluates the short-term resilient behavior of cold in-place recycled (CIR) asphalt mixtures with bitumen emulsion. The results show that water loss during curing and stiffness increase are closely related, and mixtures with 2.50% residual bitumen and 2.75% added water exhibit the best short-term stiffness evolution.

Summary: This paper evaluated the adequacy of different triaxial resilient modulus (TxRM) models for cold recycled asphalt mixtures (CRAMs) with different compositions, aggregate gradation, and physical characteristics. Three different models were selected based on the literature, and non-linear estimation was performed using the Levenberg-Marquardt algorithm. The most suitable model for CRAM's TxRM modeling was found to be Ni et al.'s model based on RSSR analysis. The model selection was independent of factors such as aggregate gradation, binder type/content, air void content, RAP content, TxRM values range, active filler type, and curing time of the tested specimens.

Summary: In this study, the self-cementing properties, permanent deformation, and resilient deformation behavior of two recycled concrete aggregates (RCA) with different self-cementing properties were investigated after different curing times. The results showed that the self-cementing properties significantly improved the mechanical behavior of RCA, comparable to lightly treated materials. The permanent strains of RCA with strong self-cementing properties decreased quickly after 180 days of curing and then stabilized. On the other hand, curing had no influence on the mechanical behavior of RCA with negligible self-cementing properties.

Summary: By conducting cyclic triaxial tests, the resilient deformation characteristics of silty filler under intermittent loading were investigated. It was found that intermittent loading had a reduction effect on resilient deformation, with the most significant reduction effect seen in incremental collapse samples. A classification criterion for deformation behaviors based on the difference of resilient strain between the first and second loading stages was proposed and verified. Additionally, a simpler method to identify the deformation behaviors of subgrade filler was presented based on the stable value of resilient strain under intermittent cyclic loading.

Summary: This paper investigates the permanent and resilient deformation behaviour, as well as the shear and physical properties of different types of recycled concrete aggregates (RCA). The results show that all RCA have acceptable physical properties and can be used in pavement construction. However, the use of concrete wastes with low strength and high amount of rounded particles can lead to poor pavement performance.

Summary: This study investigated the deformation properties of RCA/RG blends for pavement base applications. Results showed an increase in permanent strain and a decrease in M-r of blends as the RG content increased. Blends exhibited strain-hardening behavior in the post-peak zone when RG content was over 10%.

Summary: This study aims to increase knowledge about the physical and mechanical properties of basalt aggregates used as crushed-stone. Experimental tests were conducted and compared with existing specifications. The results showed that the impact resistance, abrasion resistance, and freeze-thaw durability of basalt aggregates were good, but water absorption and flakiness index were relatively high. It was found that the commonly used single-graded and static test methods did not provide sufficient information about material performance, and dynamic triaxial tests should be used to support laboratory test results. The recommended resilient modulus values for basalt aggregates were obtained using the K-theta formula, which can be used as a stiffness parameter in pavement design.

Summary: Crushed waste rocks (CWR) are commonly used in the construction of mine haul roads. In this study, RLCBR tests were found to be a simpler and more available method to estimate the resilient behavior of CWR under low and high stress levels. The good agreement between RLCBR equivalent modulus and RLT resilient modulus suggests that RLCBR tests could be an effective alternative to estimate resilient behavior of CWR used in mine haul roads.

Summary: Zero energy buildings (ZEBs) have attracted significant attention in the US, with the potential to achieve more cost-effective energy savings through new materials and systems that regulate building enclosure heat losses and gains. The study on thermo-optically responsive solid-solid phase change material (SS-PCM) coatings demonstrates their ability to reduce heat exchange in building enclosures and highlights the rooftop as the optimal location for installation. The findings also suggest that SS-PCM systems offer more thermal benefits and energy savings in warm climates compared to cold climates, presenting a promising solution for existing passive solar facades.

Summary: This study investigated the effects of pre-setting chemical exchanges on the mechanical and chemical properties of geopolymers cast and cured in saline solutions of different concentrations. Results showed that the influence of salinity and Na/Al ratio on mechanical properties varied, and there exists a critical Na/Al ratio for the highest mechanical strength of geopolymers cast in saline waters. Excessive Na+ cations diffused into the geopolymer slurry may be detrimental to strength development.

Summary: The mining of barite in Nigeria by artisanal and small-scale miners poses significant health risks due to heavy metal contamination in drinking water. Measures need to be taken to mitigate the non-carcinogenic risks associated with Ba and Pb. It is crucial for barite mining to be conducted responsibly in adherence to local and national mining regulations and global environmental standards.

Summary: A bioinspired brick-and-mortar structure has been explored to overcome the brittleness of geopolymer and enhance its mechanical performance. By using geopolymer as the brick phase and 3D-printed polymers as the mortar phase, strong and tough geopolymer composites with significantly improved toughness and strength were achieved. Various toughening mechanisms, including brick interlocking, crack bridging, and crack deflection, were revealed through experimental techniques.
