Abstract
When the unevenness quantities of the surface of a surface-treated, existing concrete are measured at a given pitch by a measuring device 10, the measured unevenness quantities are automatically collected by a CPU 21 to calculate the characteristic quantities of the surface-treated form of the existing concrete. The CPU 21 compares the calculated characteristic quantities with characteristic quantities beforehand stored in a data ROM 23 to give an evaluated result of the surface-treated form automatically. The evaluated result is displayed on a display device 40 or printed by a printer 50, so that the result can be immediately checked. An ideal surface-treated form is a surface-treated form in which the average height of unevenness of the surface of the existing concrete is from 13 to 35% of the maximum particle size of aggregates contained in the existing concrete, and the slope length ratio thereof is 1.13 or more, and the unevenness having a height of 2 mm or more occupies 14% or more of all the unevenness.
