Summary Ten groups of peanut protein powder (PPP)–soy protein isolate (SPI)/wheat gluten (WG) mixtures were prepared and extruded under the moisture content of 55%. Extrusion response parameters (specific mechanical energy (SME) and die temperature) during the extrusion were determined. Microstructure and textural properties of the extrudates were analysed. Results suggested that blending the PPP with SPI led to a lower SME and a higher die temperature during the extrusion, which led to a smoother and denser structure in the extrudates. While blending the PPP with WG resulted in a higher SME and a constant high die temperature during the extrusion, showing a rougher and looser structure in the extrudates. Compared with WG, SPI played a major role for the texturisation behaviour of PPP‐SPI‐WG mixtures during high moisture extrusion and for the extrudates. Both SPI and WG are required to improve the textural quality of texturised peanut protein.

In order to evaluate the pavement performance of recycled asphalt mixture processed by microwave, an experimental method was designed to compare the microwave heating with the conventional heating in recycling affection of asphalt mixture. The samples AC-13 were produced. Conventional and microwave heating performance of modified asphalt recycling test including the rutting test, the trabecular cold bending test, the Marshall immersion test, the freeze-thaw split test, and the splitting strength mechanical properties were test. The experimental results show that it is roughly the same in the high temperature stability and mechanical properties of these two areas, and at low temperature cracking resistance the use of microwave processing can improve the low temperature flexibility to reduce the surface temperature seasonal prone temperature shrinkage cracks and fatigue cracks. The stability on the water by using microwave processing can enhance the asphalt and aggregate adhesion so that mixture enhanced resistance to water damage, there is a better role in improving the water stability. These results could promote microwave recycling and provide the basis for the promotion applications.
