Preparation method and application of composite-layer pavement brick
The invention relates to the technical field of pavement bricks, and provides a preparation method of a composite layer pavement brick. The preparation method comprises the following steps: preparinga surface layer material by adopting a vacuum pressing method, preparing a bottom layer material by adopting a vacuum exhausting method, and connecting a bottom layer and a surface layer by adopting aconnecting layer containing gravels to increase the interface bonding force of the surface layer and the bottom layer and improve the bearing capacity of the composite layer pavement brick; and carrying out low-temperature curing treatment on the composite layer material to complete demolding, and then treating the surface of the surface layer by adopting a shot blasting treatment technology to form surfaces with different concavities and convexity. The preparation method is simple and excellent, the combination degree of the surface layer and the stratum can be improved, and it is guaranteedthat the surface layer material and the bottom layer material are not prone to falling off; and the contractibility of the material is reduced, so that the composite layer pavement brick material ishigh in bearing capacity, good in skid resistance, good in durability, low in overall manufacturing cost and suitable for wide application.
本申请涉及路面砖技术领域，提供了一种复合层路面砖的制备方法，该制备方法采用真空压制的方法制备面层材料，再采用真空排气的方法制备底层材料，在底层和面层之间采用含有碎石的连接层进行连接，以增加面层与底层的界面结合力，提高复合层路面砖的承载力；进一步对复合层材料先进行低温固化处理以完成脱模，再采用抛丸处理技术对面层表面进行处理，形成具有凹凸不同的表面，该制备方法简单优异，能够提高面层与地层的结合程度，保证面层和底层材料之间不易脱落，同时，降低材料的收缩性，使复合层路面砖材料承载力高，防滑性能好，耐久性能好，整体造价低，适合广泛应用。
