Main technical requirements: In addition to the parameters of GB/T16277, product performance parameters should include: a) driving force of the conveying device; b) rotational torque of the spiral material distribution device; c) maximum traction force. The performance parameters and characteristic values of remanufactured paver are subject to the data and test methods provided by the original manufacturer. For projects that cannot provide data and test methods, 3 new machines of the same specification can be used according to GB/T16277 and Appendix B of this standard. The arithmetic average of the data detected by the specified testing method is used as the performance parameter characteristic value of the remanufactured machine.
