PROBLEM TO BE SOLVED: To easily install a paving material employing natural soil and sand in a steep slope face or a narrow paving site. SOLUTION: The paving material is prepared by kneading of the natural soil and sand after dry treatment, an inorganic solidifying material, a soil and sand pavement material containing a permeable material or a water-absorbing and retentive material with water. This paving material is fed to a spray machine 3 with a belt conveyer 2 and compressed air is fed to the spray machine 3 with a compressor 4, and the paving material is sprayed to a paving surface through a nozzle 6. By this spraying method the paving material is gradually laid little by little and leveled on a paved surface, the paving material on the paved surface is excellent in solidifying function. The paving material is prevented from slipping along an inclined surface even in a steep inclined surface which is not less than 30°. COPYRIGHT: (C)2005,JPO&NCIPI
