This paper analyzes the effect of molding methods on asphalt stabilized macadam performance by gyratory compaction molding,vibratory compaction molding and large Mashell molding methods,and the Mashell indexes with different molding methods are also compared.

Study on the SGC and inter-lock analysis in improvement of stage filling;

Based on the advantage that the Superpave gyratory compactor(SGC) could character- ize the in-situ pavement compaction,and its operation system is convenient for data acquisition,the gyratory compaction method is adopted for the proportioning design of SMA 13.

The crumb rubber-asphalt concrete with different fineness and different blended amounts, is studied by laboratory Marshall test, gyratory compactor test and wheel tracking test in this paper.

Development of speciality resin suitable for rotational molding;

The principle and characteristics of rotational molding of plastics are introduced.

This paper mainly introduces the design principles of the rotational molding mould, the determination of mould wall thickness and the choosing of mould material.

An aqueous slurry was developed as a sort of raw materials in rotational moulding for the preparation of short glass fiber reinforced polypropylene composites.

The investigation of the drying behavior of the aqueous slurry of powdered polypropylene (PP) using sodium carboxymethylcellulose (CMC) as a suspension stabilizer during heating process in rotational moulding was carried out.

Bubble effect in aqueous slurry of powder polypropylene (PP) using poly(vinyl alcohol) (PVA) as the stabilizer which is used as a sort of raw materials in rotational moulding has been investigated.
