WB17型稳定土拌和机是用来在公路基层上直接拌和石灰土或其它稳定材料的机械。交通部新津筑路机械厂已于1980年12月制造出两台样机,进行了基本性能的测试和试验路段的拌和作业。1981年针对试验中暴露出的弱点,又对设计进行了改进,并再次进行了密集强度试验,证明该机达到了设计要求,能拌和虚铺厚度300毫米的石灰土 WB17 Stabilized Soil Mixer is a machine used to directly mix limestone or other stable materials on the grassroots level. Xinjin Road Machinery Plant of the Ministry of Communications has made two prototype machines in December 1980 to carry out the basic performance testing and the mixing of the test road sections. 1981 for the weaknesses exposed in the experiment, but also to improve the design, and re-intensive intensity test to prove that the machine has reached the design requirements, can pave the limestone thickness 300 millimeters
