<p>A porous concrete road surface structure made from polymer modified cement and a construction method thereof are disclosed. The structure successively comprises a bottom layer (4), a bonding layer (3), a porous concrete layer (2) and a surface treatment layer (1). The bonding layer (3) is located on the bottom layer (4), and the porous concrete layer (2) on the bonding layer (3) is prepared through paving, leveling and jolting a composition mixed from broken stone, sand and a slurry mixture of polymer modified cement. The addition of polymer promotes bonding of granular materials with the slurry mixture tightly, the use of the bonding layer makes the road surface structure and the bottom layer form an integral body, and the road surface structure has high strength, good crack resistance, water resistance, ageing resistance and corrosion resistance; the use of an intermittent or single graded of particles results in large pores, makes the road surface water-penetrating, decreases noise and amount of the polymer; and, the surface treatment can improve markedly surface properties and its use according to the application can make the porous concrete layer has rigid or flexible characteristic. The porous concrete road surface can be paved, leveled and jolted by paving machine or manual labor, and the invention has advantages of simplicity and convenience, and wide application.</p> |
