This paper deals with the technology in new type speed frame on the basis of a great number of original data obtained by multi-factor orthogonal test L27(313), the combination effects of parameters in speed frame on roving and spun yarn qualities are analyzied.

The model-temperature in road construction is simulated by multi-index orthogonal test,and the characteristics of three mixing methods including the dry-mixing method,wet-mixing method and compound-mixing method are elaborated,and the effects of different mixing methods and model temperatures on Marshall index of fiber-enhanced asphalt concrete are analysed in Marshall test.
