Abstract: A semi-rigid asphalt concrete that can be produced under ambient temperature by applying traditional cement concrete production method. A high temperature heating and great pressure rolling that are necessary for producing asphalt concrete in conventional skills are never being constraints while producing the semi-rigid asphalt concrete. The method of producing the semi-rigid asphalt concrete generates less air pollution than the traditional method for producing hot mix asphalt concrete. The semi-rigid asphalt concrete consists of cationic emulsified asphalt, type-I cement, F-type superplasticizer, Na-Carboxymethyl Cellulose (Na-CMC), calcium chloride(CaCl.sub.2), stone dust, and III d, IV b, or VII a gradation aggregates. By applying the procedure of producing cement concrete, the semi-rigid asphalt concrete is completely produced after mixing, placing, and curing. The cationic emulsified asphalt and the F-type superplasticizer are first mixed to generate a mixture, and then pour the prepared CaCl.sub.
