Concrete and asphalt overlay construction equipment and the construction methods

摘要

The present invention relates to a concrete and asphalt pavement overlay construction device and construction method, the primary coating to reinforce the damaged part of the road and maintain the smoothness of the road by applying a mineral emulsion mixed with the oil on the cracked road surface Apply a layer; A second coating layer is applied by re-coating a mineral oil mixture mixed with an emulsion on the first coating layer; The primary coating layer is applied 8mm, the secondary coating layer is made by applying 7mm; The mineral oil, 5 ~ 10mm aggregate 20 ~ 24% by weight, 0.5 ~ 5mm stone powder 46 ~ 50% by weight, emulsion 14.5 ~ 18.5% by weight, cement 1.1 ~ 5.1% by weight, water 8.4 ~ 12.4% by weight is mixed Is done; The emulsion is made of a mixture of bitumin 33.2 to 37.2 wt%, emulsifier 1.3 to 1.7 wt%, hydrochloric acid 1.0 to 1.4 wt%, latex 1.9 to 2.3 wt%, and water 58 to 62 wt%. Therefore, the work of removing concrete and asphalt is eliminated because the cracked pavement surface is applied directly on the pavement surface without being removed, and accordingly, not only the air is shortened by that amount, but also does not incur waste disposal costs, thus significantly reducing the construction cost. Can. In addition, bitumin, emulsifier, hydrochloric acid, latex, and an emulsion in which water is mixed in a certain ratio are mixed with aggregate, stone, cement, and water in a certain ratio to form a mineral oil, and the mineral oil is strong in calcium chloride and has excellent waterproof function. Therefore, it is possible to minimize the coating thickness on concrete or asphalt.
