摘要： PROBLEM TO BE SOLVED: To provide a form-type color tile and a tiling method therewith which a sufficiently satisfactory hue can be obtained in a color pavement or the like. SOLUTION: Lustrous fine pieces 2 are scattered and fixed onto the surface of a tile 1. Fine pieces of a material such as metal, paper, or the like, for instance are used for the lustrous fine pieces 2. Above all, fine pieces of metal foil are favorably used. Fine pieces of aluminum foil colored with acrylic resin are more favorably used. The lustrous fine pieces 2 are scattered on the surface of the tile 1 immediately after the tiles have been finished to form the tile part 2, that is, immediately after the tiles are applied so that the finished height becomes flush with the upper face level of a bar-shaped form. In this way, after the applied tiles have cured, the lustrous fine pieces 2 can be fixed onto the surface of the tile 1.

摘要： PROBLEM TO BE SOLVED: To restrain scattering of an aggregate, to reduce traveling noise, to enhance safety, and to provide a beautiful appearance of the finish of a surface by using a crushed stone for enhancing uniformity of the grain size and uniformity of a grain shape by selecting the grain size and the grain shape as the aggregate. SOLUTION: A crushed stone on which a vertical difference is within 3 mm in conversion of sieve opening and the ratio of a long diameter to a short diameter is not less than 1.6 is removed, and is selected by using a difference in repulsion when an aggregate 1 strikes on a collision plate 2. In this case, the sieve opening is arranged so as to be vertically dislocated, and the aggregate 1 having the large ratio of a long diameter to a short diameter is selectively left on the sieve opening. The crushed stone for enhancing uniformity of the grain size and a grain shape is used as the aggregate 1 to perform surface treatment of a road surface to repair and refresh a flowing road surface, an abraded road surface and a cracked road surface. The crushed stone is applied to an asphalt road surface, the surface is heated and faired when necessary, and a bitumen material is sprayed on it. Thus, the aggregate 1 is sprayed, rolled and compacted to increase sticking force of the aggregate 1 to restrain scattering of the aggregate 1 to reduce traveling noise.

摘要： PROBLEM TO BE SOLVED: To provide a control method in which a paved face is controlled carefully as a whole, a measuring operation is mechanized and in which labor and skill are saved. SOLUTION: A moving carriage 2 to which a measuring mark target 1 is attached is run along a plurality of measuring lines 4a, 4b, 4c which are set on a paved face to be measured, the movement of the target 1 is measured repeatedly at very small time intervals by using a three-dimensional position measuring device 5 which is installed in advance on the ground, and three- dimensional positions of the respective measuring lines 4a, 4b, 4c are found on the basis of position data on the measured target 1. Then, a control method is featured in such a way that the found position data are plotted in a three- dimensional rectangular coordinate space, that many plotted points 22a, 22b, 22c,... are connected by line segments so as to draw polygonal lines 23a, 23b, 23c,... which correspond to the respective measuring lines 4a, 4b, 4c and that, on the basis of the height coordinates of the respective drawn polygonal lines, the flatness of a road surface which is based on a paved height, a paved thickness, a paved width and a power spectrum density is computed so as to be collated with a design value and a reference value for finished-shaped control.

摘要： PROBLEM TO BE SOLVED: To reduce time and labor required for sorting pavement waste and curb equipment investment in recycling plants by paving a mixture of pavement waste where a binder is added to pavement waste and providing a surface protection layer over the top for storage. SOLUTION: Pavement waste is obtained by cutting draining type pavement for which a recycling technique has not been established yet, with a cutting machine. A storage layer of pavement waste is built by laying and leveling a mixture of pavement waste where a binder is added to pavement waste with a laying and leveling machine and compacting with a compactor. To store and protect the storage layer of pavement waste, a surface protection layer of a thin asphalt draining type pavement is provided on the top, thereby storing pavement waste in a present site, reducing significantly transport, sorting and equipment costs involved in the storage of waste. The provision of the surface protection layer helps store pavement waste without allowing an entrance of foreign matter until a recycling technique is established and making it a raw material immediately when the recycling technique is established.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for reconstructing a drainable paved layer by heating for regeneration of an existing draining pavement and putting a thin layer of draining pavement on the draining pavement. SOLUTION: This method of regenerating the surface layer of an existing draining paved layer formed by uniformly laying down a draining pavement material formed of aggregate, sand, stone dust, and binder containing asphalt on the surface of the existing draining paved layer in the state of remaining spaces between the aggregate, comprises the steps of heating the existing paved surface layer, scratching the heated existing road surface layer 12, removing a part of the scratched draining pavement material, and re-laying down the pavement material, feeding new draining pavement material, and uniformly laying down the fed new draining paving material. By heating the surface of the existing paved layer, the asphalt binder in the existing paved layer is molten and the flowability of the aggregate is increased, and a thin layer pavement is applied onto the existing paved layer.
