The invention discloses a cement-base colored microsurface, belonging to the technical field of road engineering. The microsurface pavement comprises a cement-base layer, wherein the cement-base layer comprises the following components in parts by mass: 100 parts of cement, 150-170 parts of colored quartz sand, 50 parts of water, 7 parts of waterproofing agent and 10 parts of pigment; and the cement-base layer also comprises 0.1 vol% of polyvinyl alcohol fiber and a right amount of modifier. The modifier is composed of a water-based epoxy resin (the mass ratio of the water-based epoxy resin to the cement is (8-12):100) and a curing agent (the mass ratio of the curing agent to the water-based epoxy resin is 1.3:1), or hydroxy cellulose (the mass ratio of the hydroxy cellulose to the water is 3:100), or a water-based organic silicon resin (the mass ratio of the water-based organic silicon resin to the cement is 2.5:100). The color of the colored quartz sand has the same color system as the color of the pigment. The invention also discloses a construction method of the cement-base colored microsurface. The cement-base colored microsurface has the advantages of higher water resistance, higher crack resistance, higher wear resistance, higher color distinction degree and high color durability, and is easy for construction.
