# Mixing: The proportion of the aggregate: cement: water: additive in the coloured Pervious Concrete is in accordance with the combination. JS500W mixer is selected and stirred for more than 5 minutes.
# Pouring: Before pouring, the roadbed should be wet with water, and the Pervious Concrete mixture is relatively hard. The mixtures of previous Concrete should be spread with benchmarking.
# Tamping: Choose a flat-plate vibrator of light vibration, light vibration can ensure the porosity of the pavement and increase the effectiveness of water permeability.
# Levelling: After tamping, use a polishing machine to flatten the permeable road surface to increase its flatness.
# Maintenance: After levelling, the surface needs to be covered with plastic film, in order to keep the water does not volatilize. The 2nd day, Pervious Concrete begins to be sprayed with water for curing. During spraying, water is poured from top to bottom through water pipes. Generally, Pervious Concrete is sprayed for curing for 7 days.
Cold Applied Porous Asphalt, also called the newest type of Color Asphalt, is a new generation of pavement colour paving system based on reactive inorganic materials modified polymers. Its main components are modified decolourized asphalt synthetic resin, additives, curing agent and so on. It is a low mixing viscosity at room temperature with long service life and moderate curing speed at medium and low temperature.
The cured product has high mechanical strength, good adhesion, small shrinkage and great weather resistance. It had not only the rigidity of inorganic materials but also combined with the flexibility of organic materials, which kept synchronous shrinkage with the road surface ability. With not easily cracking, anti-skid wear, environmental protection, Porous Asphalt is the new environmental protection porous colour asphalt pavement.
Great anti-skid: Color Permeable Asphalt pavement has good anti-skid performance, which can effectively reduce the braking distance and improve driving safety.
Fast construction cycle: Its construction is fast and efficient, effectively reducing traffic delays caused by construction.
Good noise reduction effect: the fine aggregate structure of Color Permeable Asphalt has the effect of conducting audio frequency, which can reduce the noise of 3~4 dB when used in cement pavement.
Good visual sense: different colour road surface effectively enhances the road colour brightness, greatly improves the road surface perception effect.
