Water Damage

In order to address water damage of asphalt pavement, reduce the occurrence of water-related potholes, deformation, and other diseases, and improve the performance and service life of the pavement, a nano-TiO2 superhydrophobic coating (PSC) on asphalt pavement was prepared from waterborne polyurethane and nano-TiO2 modified by stearic acid. FT-IR measured stearic acid successfully modified low surface energy substance on the surface of nano-TiO2. The SEM image shows that the PSC has a rough surface structure. The contact angle and rolling angle of the PSC in the contact angle test are 153.5° and 4.7°, respectively. PSC has a super-hydrophobic ability, which can improve the water stability of the asphalt mixture. Although the texture depth and pendulum value have been reduced by 2.5% and 4.4%, respectively, they all comply with the standard requirements. After the abrasion resistance test, the PSC coating still has a certain hydrophobic ability. These results surface PSC coating can effectively reduce water damage on asphalt pavement, and has considerable application value.

In paper new setup for studying the thermal transfer of nanofluid in the steel micro-channel with inner diameter 358 microns is described. Setup testing carried out by means of known experimental data about thermal transport of the water. Then the data about the thermal tranfer coefficient of the water based nanofluids with silicon dioxide nanoparticle with average size 25 nm are discussed. It was shown that nanofluids have the thermal transfer coefficient much more than that of base liquid. The enhancement of the thermal transfer coefficient of one-percent nanofluid is about 60 %. This enhancement grows with increasing of the nanoparticles volume fraction and flow rate of the nanofluid.
