Summary: The effect of different warm mix asphalt (WMA) technologies on the moisture resistance of asphalt mixtures was studied. It was found that moisture damage in WMA mixtures was influenced by aggregate type and base asphalt binder. Rediset, a chemical WMA additive, showed higher moisture resistance compared to other technologies. Correlations were observed between bond strength ratio (BSR) and tensile strength ratio (TSR), with a minimum BSR of 0.7 suggested for satisfactory performance against moisture damage.

Summary: The study evaluates the performance of recycled asphalt binders prepared using warm-mix recycling technology in terms of linear viscoelasticity, rutting resistance, fatigue resistance, and low-temperature crack resistance. Different warm mix asphalt (WMA) technologies and modifiers have significant effects on the performance of recycled binders. The addition of crumb rubber powder (CRP) in warm-mix recycled binders shows the best comprehensive performance, and suitable modifiers are recommended to compensate for the loss of pavement performance caused by the use of WMA technologies and RAP.

Summary: The aging performance and durability of foamed warm mix asphalt (FWMA) have not been fully studied. This study examined and evaluated the performance variation of FWMA compared to conventional hot mix asphalt (HMA) under long-term service conditions. The results showed that the aging resistance of FWMA was slightly diminished under construction conditions with no temperature reduction, but improved at high temperatures and deteriorated at low temperatures with increased service time. The foaming water and service time were primary determinants of the aging and rheological properties of FWMA.

Summary: Global warming and reduced energy resources are driving the search for alternative materials and technologies for pavement construction. This research focused on investigating the mechanical and durability performance of WMA mixtures containing reclaimed asphalt pavement (RAP) with different types of additives. Results showed that the performance of the mixtures varied depending on the WMA additive, with PAWMA (R) decreasing resistance to moisture damage. Despite decreasing flexibility and cracking resistance, incorporating RAP material led to improved resistance to rutting. Mixtures containing RAP and Kaowax (R) had the highest flow number value, while those with Zeolite (R) had the lowest. Furthermore, mixtures containing RAP and PAWMA (R) showed the highest resistance to moisture damage and best resilient modulus and cracking resistance among all mixtures studied.

Summary: The use of ultra-thin layers (AUTL) raises concerns about the applicability of current characterization tests for small thicknesses of 10-20 mm. The guillotine type clamps used in shear tests can be problematic for thicknesses below 20 mm, leading to regulations requiring minimum layer thicknesses. This study investigates alternative tests, including shear tests, tensile tests, a Fenix test adaptation, torsion tests, and fatigue tests, to determine their validity when one layer is thin. Results show that all tests can effectively distinguish between different tack coat dosages.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
