As we all know,Asphalt concrete is made by artificial matching and consisted of some graded mineral aggregate and a certain proportion road bituminous material. It is a mixture formed under strictly controlled conditions. The raw materials are crushed stone, crushed gravel, stone chips or sand and others.

Asphalt concrete can be divided into two kinds: petroleum asphalt and coal tar pitch according to the combined different materials. Some countries or areas also use or mix natural asphalt. The used materials can be with crushed stone, gravel, sand and slag, of which the asphalt concrete with slag is the best and its prospect is blue.

Ground Granulated Blast Slag is also called mineral powder. Nowadays slag is mainly applied in concrete admixture. These are produced in professional factory and make concrete into manufacturing this kind concrete; the amount to mix is same to the cement in the concrete. GGBS can be equal to cement in various usage of concrete and cement products. This can significantly improve the overall performance of concrete and cement products. GGBS as a new high-performance concrete admixture can improve concrete performance.
