Abstract Despite significant economic and environmental benefits, performance of warm mix asphalt (WMA) containing reclaimed pavement (RAP) remains a matter concern. Among the current WMA technologies, plant foaming technique (called “foamed WMA” in this study) has gained most attention, since it eliminates need for chemical additives. In present study, laboratory performance, namely rutting mo...

Transformants of the Trichoderma reesei strains QM9414 and Rut-C30 were constructed in which the genes for the two major hydrophobin proteins, hydrophobins I (HFBI) and II (HFBII), were deleted or amplified by molecular biological techniques. Growth parameters and foam production of the transformant strains were compared with the corresponding properties of the parent strains by cultivation in ...

Free radical polymerization is one of the most widely employed polymerization techniques. This technique is applied to prepare latexes to be used in paints, high molecular weight poly (methyl methacrylate) for safety glass (Plexiglas), or foamed poly (styrene) to be applied in coffee cups. Some advantages of radical polymerizations, with respect to other techniques, are the relative insensitivi...

ement integrity achieved in the Gulf of Mexico Marco Polo development in Green Canyon block 608 is putting innovative slurry systems on the map of sought-after technologies for deepwater plays. These new slurries help reduce the known risk of shallow flow and combat possible formation of gas hydrates. While Anadarko considered conventional foamed slurries in the planning phase of this 20-in. co...

A metamaterial structure formed by foamed metal and starch and oil-based electrorheological (ER) fluid is designed in this paper. Experiments show that the metamaterial structure exhibits a regulation effect on the amplitude and phase of the transmitted waves of 35–80 kHz ultrawideband ultrasonic waves in water. With the increase of the electric field, the transmission amplitude and phase of th...

In this study pure Al and pre-alloyed Al alloy powders (Alumix 231Al-Cu %2.5-Mg %0.5–Si %14) with or without reinforcing elements were used to produce classical Al foam or spherical Al foam with various production parameters by using powder metallurgy route and the results obtained have been discussed. Al2O3 and SiC particles were used as reinforcing elements and TiH2 powders were used as foami...
