Description

Asphalt sidewalk block and it's installation method [

The present invention relates to a method of installing an asphalt pavement block and an asphalt pavement block which are manufactured using asphalt as a main component. Generally, since the asphalt is weak to heat, it is difficult to produce a pavement block, And the coating layer is formed on the upper part to protect the sidewall block and various additives are added to the sidewalls formed between the adjacent blocks to change the color of the joint part or to increase the aesthetic effect of the joint part such as reflecting light I will.

Generally, blocks are made of concrete blocks using cement and aggregate or elastic blocks made of rubber chips. However, there is a problem that a large amount of carbon dioxide is generated due to the use of cement recently, and there is a problem that a relatively long curing period is required to produce a concrete block. In addition, various problems have arisen, such as a resin used as a binder in the production of an elastic block, such as harmful substances to the human body.

Since asphalt is generally weak at high temperatures and has a larger porosity than other materials, it has been difficult to produce as a block. Therefore, asphalt was mainly used to form a car which car moves, and showed advantages such as short curing period, noise reduction, and improvement of running ability.
