“…Most existing studies in the literature have focused on optimal design solutions for BTES, considering among others (i) the existing ground and climate conditions [9][10][11], (ii) the occurring heating and cooling demands [11,12], (iii) the integration of a BTES with other systems [9,[13][14][15], (iv) key parameters for optimal (dis-)charging [16][17][18], and (v) advanced materials in the borehole grouting to improve heat storage [19]. In contrast, there has been little focus on evaluating existing BTES and considering strategies to improve their operation.…”

“…Researchers modified asphalt by adding polymers to improve the road performance of asphalt [19][20][21]. After the use of rubber as an asphalt modifier, more and more polymers have been used in the field of modified asphalt [22][23][24][25] whose properties are different, and their modification effects on asphalt are different.…”

The mechanical properties of polyurethane grouting materials were significantly improved when cement, sodium meta-silicate, red mud, slag, and fly ash were added. However, the grouting mechanisms of polyurethane composite materials are not clear. The grouting mechanisms of polyurethane composite materials in asphalt pavement subsidence were investigated. The results of computed tomography analysis show that polyurethane foam is filled with geopolymer hydration products. The results from ground penetrating radar after grouting show that mapping has no significant fluctuation or dislocation effect, which indicates that the grouting effect is strong. The high-density electrometer can also test the pavement subsidence place and distribution. The grouting mechanisms indicate that polyurethane foam acts as the consolidation structure, and the geopolymer filled with the foam pores of polyurethane and geopolymer forms a stable consolidated body. The seriflux includes under-layer seriflux (red mud, slag, water, and polyurethane composite materials) and upper-layer seriflux (polyurethane seriflux), and there exists a weak phase separation phenomenon, in which the separation phase is mainly polyurethane with little red mud-based geopolymer.
