2.1 There are simple? steps for process:

1). Mixed with Part A and Part B thoroughly,

2). Pour aggregate into the mixer, then pour Part A and B mixture into the mixer and stir for 2  minutes.

3). Using transport tools to transfer the ready materials to the on-site.

4).Level the surface in good condition.

5). Locked down the on-site, cover and protect the finished area.

6). Reopen the area after 24 hours in summer, and after 48 hours in winter.

2.2 We need to confirm all materials(Mixer & Stone) and on-site is under dry condition, otherwise it can cause to fail.

Here are some key points you need to pay more attention :

1). Water and resin can’t mix together

2). Ensure Part A and B are mixed in dry conditions

3). The mixer must keep dry

4). Make sure the substrate is in dry condition

5). Part A and B can’t be mixed more than 2 minutes

6). The ready materials to the on-site distance can’t be too far away, because the ready materials will be freeze after 20 minutes.

# 4.3 Mainly the difference between Cold and Hot-Applied Asphalt

Because of asphalt’s practical and aesthetic, coloured asphalt is widely used. Now there are two types of coloured asphalt on the market, one is hot-applied Asphalt, and the other is Cold-applied  Asphalt material. The two kinds of materials have their own characteristics and advantages. Hot-applied Asphalt needs to be heated and stirred at high temperature. The mixing temperature of aggregate and asphalt is 160-175 degrees. In order to maintain good construction effect, the construction temperature should not be lower than 110 degrees. Compared with Hot-applied Asphalt, cold-applied Asphalt construction is much simpler, no subject to the season, weather, temperature restrictions, and can be used at regular temperature, the construction process is simple, can be used as needed according to the actual situation, reduce the waste of resources, and cold filling asphalt pavement is not easy to appear temperature shrinkage cracks.

Cold Applied Porous Asphalt has persistent adhesive, which like a breathable material can effectively resist damp and hot environment alternately road surface deformation. Its surface is smooth and non-slip, wearing resistant, and can improve the safety of traffic and pedestrians. As a newly breathable type of sponge city material, with air permeable, great compressive strength, high permeable coefficient, so it not only beautify the road with colourful combination plan but also eliminating Hot Applied Asphalt weakness as depending on the hot source and complicated construction conditions, which made its construction is efficient.

Sponge city actually means that a city, like a sponge, has good “elasticity” in adapting to environmental changes and responding to natural disasters. It can absorb water, store water, seeping water and purify water when it rains, and “release” the stored water when it is needed.

Cold Applied Color Porous Asphalt is a new material for environmental protection permeable asphalt pavement and also a new environmental protection material in sponge city construction.
