Abstract

PURPOSE:To secure abradability, the applicability in paving work, and the oil absorbing properties after application by adding water to a mixture of a powdered or cake-like zeolite with a specific binder and/or a property modifier, then forming the mixture into blocks, and curing and drying the blocks. CONSTITUTION:A powdered or cake-like zeolite is mixed with 20-75% binder selected from the group consisting of a cement, fine blast furnace slag powder, and fly ash and/or property modifier to give a mixture. After is added to the mixture, it is granulated or press molded into blocks, cured by steam or at room temp., and dried to give an oil-absorbing aggregate having an oil- absorption of 30-100%.

BACKGROUND OF THE INVENTION Zeolites are produced naturally, artificially, or synthetically, and their porous properties are utilized for a variety of applications, such as adsorbents, deodorizing materials, and soil improvement materials. The use and amount of zeolite used has been limited due to the balance between its manufacturing cost and porous properties.

Therefore, especially in the summer, direct sunlight damages the road surface by 7.
It is heated to nearly 0°C, and the light oil in the asphalt seeps out onto the road surface, softening and becoming fluid. When a heavy vehicle or the like passes through a road surface in such a state, it deforms and causes ruts, etc., shortening the lifespan of asphalt pavement.

In addition, when the light oil content in the asphalt of an asphalt-paved road evaporates, the binder effect decreases, causing various aggregates and fillers to flake off, shortening the life of the asphalt.

The present invention aims to provide not only workability but also long-term stability by applying the above-mentioned artificial zeolite to a part of the aggregate, which is an asphalt pavement material, by retaining the light oil content in the asphalt for a long period of time. However, as a road aggregate, a corresponding level of strength is required.

In this case, if the amount of the binder and/or property modifier is less than 20% of the powder or cake zeolite, the abrasion properties of the agglomerated material will be poor and the strength as an aggregate cannot be achieved.

In addition, one or more of cement, pulverized blast furnace slag, and fly ash may be mixed with the powder or cake-like zeolite of the present invention as a binder and/or property modifier.
In oil-absorbing aggregates that have been agglomerated and have an oil absorption of 30 to 100%, if the oil absorption is less than 30%, the abrasion resistance of the agglomerates is comparable, but after the construction of an asphalt paved road. Light oil content becomes insufficiently captured when the temperature rises due to direct sunlight.
