he expressway is complex due to various vehicles and harsh environment. The road has a long service life and is troublesome to maintain, and the drainage requirements are high when the road passes through the city.

Before the drainage of highways in countries, the drainage covers were mainly made of cast iron or cement. However, because cast iron is easy to be stolen, while cement has a relatively low bearing capacity and is easy to aging, the highway drainage with a long service life has basically collapsed. The SMC drainage kerb developed by Avatar possesses the following advantages:

1. High load-carrying requirements,

2. Good aging resistance, which can last for more than 100 years,

3. No recycling value,

4. Beautiful appearance,

5. The product is light in weight, easy to install and maintain,

6. The surface can be made into a yellow ribbon of reflective material to guide vehicles driving at night.
