In the hot summer, walking in traffic, blatant noisy streets and concrete cities, outdoor temperature is 38 ℃, the surface temperature is 40 ℃ +,  people feel inevitably irritable, heart internal heat. People in order to avoid the heat, tend to close themselves in a small air-conditioned room or go to the suburbs to travel, so the city began to become empty, deserted.

Why is the actual temperature of urban streets much higher than that of rural areas in summer? Because specific heat capacity C=Q/m (m stand for quality, △T stand for temperature difference), the specific heat capacity cement and concrete is relatively small  in the case of absorbing the same solar heat, the temperature will rise higher; And in the countryside, trees, rivers crisscrossing, cement relatively few, nature to cool a lot.

In recent years, in order to solve the problem that urban roads are too hot, local governments have started to build urban roads with more and more plastic and wood materials instead of the traditional reinforced concrete, which is very popular among local residents.

Second, wpc material has the advantages of insect control, corrosion prevention and non-cracking while having the appearance of wood. In addition, the price of real wood is higher, and a large number of trees will be cut down. The wpc material is made of wood fiber and recycled plastic, which is more economical and environmentally friendly. That's why the wpc material is used instead of the real wood directly.

But due to the mixed wpc material market and the manufacturer is mixed and disorderly, No all of the wpc material are suitable for urban road construction, for example, some wpc material  (HDPE, PS) can only be applied to interior decoration, because of the characteristic of the PE, PS plastic component, this kind of wpc materials easy to stretch and deform in outdoor heating, wind rain environment , adding extra maintenance costs.
