| Abstract: | The present paper descusses the deficiencies of gradation composition of bituminous mixture on existing norm. In order to make best use of the function of the aggregate gradation, and satisfy thd demands of its pavement performance with high type road, the design theory and method of bituminous mixture gradation was developed and presented on aggregate volume batching in this paper. The results of laboratory test and field test clearly showed that the method is reasonable, simple and practicable. Bitumen being saved, pavement fatigue life and maintenance period being growed. as well as obvious economic benefit and technical meaning by using the design method, It is suitable for construction departments spread and adopt it. |
