A novel multiphase composite was developed to prevent premature failure of waterproofing layers in pig houses. The system, comprising polyurethane, asphalt, and calcium carbonate, achieves a 1.35 MPa bonding strength and resists corrosion via a synergistic crosslinking, buffering, and passivation mechanism.

Development of Cold In-Place Recycling with Bitumen Emulsion and Biomass Bottom Ash
Power generation from biomass is one of the most promising energy sources available today. However, this industry has a series of wastes derived from its activity, mainly biomass fly ash and biomass bottom ash.

Experimental methods in chemical engineering: Electrospinning
Abstract Electrospinning produces micro‐ and nanofibres by forcing a polymeric solution through a fine needle in an electric field that produces a filament that accumulates onto a collector plate. The fibre morphology depends on solution properties, distance between needle and plate, feed rate, and electric field intensity.

Assessing pavement sustainability requires jointly evaluating structural performance and environmental impacts, yet these dimensions are often analyzed separately. This study proposes an integrated framework combining mechanistic–empirical pavement design and life cycle assessment (LCA) to quantify the structural–environmental trade‐off associated with

Laboratory Performance Evaluation of CIR-Emulsion and it Comparison Against CIR-Form Test Result from Phase II, Final Report TR-578 Phase III, December 2009 [PDF]
Currently, no standard mix design procedure is available for CIR-emulsion in Iowa. The CIR-foam mix design process developed during the previous phase is applied for CIR-emulsion mixtures with varying emulsified asphalt contents.

To address the technical bottlenecks associated with the poor overall performance of emulsified asphalt mixtures incorporating high‐proportion (84 wt%) recycled asphalt pavement (RAP) aggregates, this study proposes a synergistic modification strategy using styrene‐butadiene rubber (SBR) and nano‐silica (SiO2), coupled with the regulation of cement and

Improving the Behavior of Cold Mix Asphalt With Induction Heating After Asphalt Paving
Cold asphalt exhibits weaker mechanical properties (stiffness, deformation, and fatigue, etc.) and moisture resistance compared to hot mix asphalt (HMA). Its high moisture sensitivity is due to its low‐temperature production, which manifests as poor adhesion between bitumen and aggregates.
