、この合材は次のようにして製造していた。In general, room-temperature bituminous paving mixtures, which can be paved at room temperature, are used for simple paving of road surfaces and repair work for sunken road surfaces because they do not require temperature control and can be stored. Conventionally, this composite material was manufactured as follows.

質物舗装用合材が製造される。Aggregates heated and dried in a dryer are classified into several types by passing through a vibrating sieve, and each type of aggregate after classification is weighed in a weighing tank and fed into a mixer. At the same time as this addition, stone powder (filler) measured in a stone powder measuring tank is added and mixed dry, and this is mixed with asphalt from the asphalt tank.
When a mixture of heavy oil A from the heavy oil tank, a small amount of rubber solution, and/or anti-peeling agent, i.e. cut hack asphalt, is added and kneaded, the surface of the aggregate is covered with a coating layer containing a mixture of stone powder and cant back asphalt. A room-temperature bituminous material pavement mixture is manufactured.

って、施工時期や施工場所によっては強度不足と耐久性
の不足から使用できないことがある。Paving with room-temperature bituminous paving mix is often done by lowering the viscosity of the bituminous binder, which improves workability and compacts with a small number of compactions, reducing the number of bot holes in the road surface. It is often used for filling holes and sliding work such as lining boards, and may also be used when the road structure is weak. However, if the viscosity is reduced, in hot weather or on roads where heavy vehicles pass, risks such as the formation of ruts shortly after construction are likely to occur, and especially in areas where rainwater tends to accumulate, rainwater often scatters after construction. . Therefore, depending on the construction time and construction location, it may not be possible to use it due to insufficient strength and durability.

る。Figure 5 shows the aggregate particles when room-temperature composite material is produced by the above method, and the surface of aggregate A is coated with a mixture coating layer of slaked lime and stone powder (slaked lime layer) The mixture is coated with three layers: a coating layer (asphalt N) Y, which is a mixture of cantobank asphalt, and a coating layer Z, which is a mixture of spindle oil and dimer acid (additive layer). The mixture in this state has low viscosity and flexibility, but when it receives a certain load due to compaction during paving, a mixture of spindle oil and dimer acid forms on the outermost part of aggregate A. Dimer acid in the coating layer (additive layer) Z combines with calcium in the slaked lime layer X to accelerate hardening.

優れた常温合材が得られる。As is clear from the above explanation, according to the method and apparatus for producing a mixture for room-temperature bituminous pavement of the present invention, slaked lime silos, spindle oil, and dimer acid can be combined without making major design changes to existing asphalt plants. or a mixture of heavy oil and dimer acid. By simply installing a new tank, it is possible to produce a room-temperature composite material with excellent workability and durability. In addition, by adding a mixture of spindle oil and dimer acid or a mixture of heavy oil and dimer acid, the aggregate is covered with a coating layer of this additive, so that it can be combined without impairing the extensibility or adhesion of asphalt. The viscosity of the material can be reduced, which greatly improves the workability during paving. In addition, during compaction, dimer acid and calcium in the mixture of spindle oil and dimer acid or the mixture of heavy oil and dimer acid can be reduced. chemically reacts and accelerates the curing speed of the composite material, resulting in a sufficient degree of compaction even with a small number of compactions, improving work efficiency, and creating a room-temperature composite material with high strength and excellent durability. is obtained.

きる。Furthermore, strength is developed without being hindered by rain during or immediately after construction, and stable paving is always possible.
