The surface properties of pavement concrete have great influence on the overall performance of pavement, so it is of great significance to study how to effectively strengthen the surface properties of pavement concrete. The surface properties of pavement concrete are mainly reflected in three aspects: abrasion resistance, frost resistance, and impact resistance. The ways to strengthen the surface properties of pavement concrete are mainly focused on surface fortifier, adding polymer mixture, fiber, and additive, improving the way of maintenance, improving construction technology and optimizing the basic components of concrete. These five ways have its advantages and disadvantages. To enhance the surface properties of concrete economically, effectively and comprehensively, the way that laying fiber mesh into cement mortar layer is put forward.

At present, fiber-reinforced solidified soil is a research hotspot in the civil engineering field, but there are few related researches. Researches mainly focus on solidified soil and fiber-reinforced soil. Based on this, the research status of solidified soil and fiber reinforced soil is comprehensively analyzed in this paper. It is found that there is still a great lack of research on the strengthening mechanism of solidified soil. The research on the mechanism is still in the stage of qualitative description, and the related technical problems need to be further studied. Similarly, there are still great limitations in the research of fiber reinforced soil. These are reflected in the limited types of soil studied, more laboratory mechanical properties tests, but less research on fiber toughening mechanism.
