Abstract

The invention provides a permeable concrete pavement protection agent and a preparation method thereof. The permeable concrete pavement protection agent contains the following components (shown in the description), can improve the bonding properties of pavement aggregates, can improve the water permeable performance of a pavement and effectively prevent concrete whiskering, can make a pavement color more uniform, brighter and more durable, and meanwhile can also slow down the carbonization and aging speed of permeable pavement concrete and improve the usage durability of ecological pavements.

Description

Technical field [0001] The invention relates to the technical field of additives in pavement mixtures, and more specifically, to a permeable concrete pavement protective agent and a preparation method thereof. Background technique [0002] Permeable concrete is an ecological and environmentally friendly concrete with continuous pores, good air and water permeability. The paving of permeable concrete pavement can replenish groundwater, relieve urban waterlogging, absorb sound and reduce noise, improve the urban thermal environment, and have good environmental and social benefits. [0003] At present, the permeable concrete pavement is mainly based on cement concrete, inorganic concrete permeable pavement and asphalt permeable pavement. However, the surface of this type of permeable pavement has the characteristics of easy effusion and blooming, dull and single color, and small particles on the pavement surface are easy to run out and permeable. There are many problems such as the i...
