Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The aspheric composition for pavement emergency repair according to the present invention is basically composed of
Asphalt containing aggregate and limestone and binder as solvent and vegetable oil, and fiber additive,
91 to 96 parts by weight of aggregate and abrasive powder per 100 parts by weight of the total composition;
3 to 6 parts by weight of an asphalt containing a solvent, vegetable oil, vegetable rosin and a mixture of thermoplastic rubber and acetone as a binder;
And 0.1 to 0.25 parts by weight of a fiber additive.
The aggregate having a particle size of 3 to 5 mm was used so that the porosity was relatively uniform.
The above-mentioned abrasive grains having a particle size of 1 to 2 mm were used.
The asphalt as a binder contains 3 to 6 parts by weight with respect to 100 parts by weight of the total composition. Acetone is used as a solvent and lemon extract is used as a vegetable oil. Acetone and lemon extract, which are used for erasing manicure, It is much more environmentally friendly than the solvents used, such as gasoline, kerosene and heavy oil.
The asphalt as the binder includes 15 to 25 parts by weight of acetone, 5 to 10 parts by weight of lemon extract, 10 to 30 parts by weight of vegetable rosin, and 5 to 10 parts by weight of a mixture of thermoplastic rubber and acetone, relative to 100 parts by weight of asphalt.
The fiber additive includes 0.1 to 0.25 parts by weight based on 100 parts by weight of the total composition. The fiber additive used herein is a cellulosic fiber, which is environment-friendly fiber. The fiber additive is not more than 1 mm in consideration of the strength, elongation, Of a short fiber is used.
Particularly, when cellulose fibers were added to the binder made of asphalt and vegetable oil, lemon extract, more excellent physical properties were shown, especially when 0.1 to 0.25 part by weight was included.
Further, it is more preferable that a surfactant is further added to the binder, and the amount thereof is 0.1 to 0.9 part by weight, particularly preferably 0.5 part by weight.
Surfactants are substances that have both polar and nonpolar groups in one molecule. The polar part of the surfactant acts on the water (polar part) existing on the existing damaged surface, and the polar part of the surfactant acts on the existing broken surface. The non-polar group acts to make the construction possible even in the presence of moisture and strengthens the resistance to moisture after construction.
An asphalt-based coating film peeling inhibitor, adhesion promoter, resin, biting agent and the like may further be added to the aspheric composition for road pavement emergency repair of the present invention.
The following table compares the test results of the properties of the ascon compositions according to the present invention with those of conventional ascon compositions.
