1、 Introduction to Asphalt Elongation Tester:
The LYY-7A intelligent asphalt elongation tester is a newly developed and popularized intelligent elongation tester by our company. This instrument adopts new computer technology and has a qualitative leap in technical parameters and performance compared to ordinary digital display products. The refrigeration system adopts imported components, is equipped with a circulation system, and adopts PID and fuzzy control algorithms for stable temperature. The bath is equipped with concealed internal lighting, a stainless steel bottom plate, and a transparent cover. The stretching system adopts ball screws and linear guides for smooth stretching. The stretching speed is infinitely adjustable by the incoming frequency converter, which can return to its original position at high speed. The control system adopts a dual CPU design, and the human-machine interface adopts a Chinese LCD screen with touch sensitive button operation. The interface is simple and friendly, and the operation is easy Execution standard: Complies with GB/T4508JTJ/T0606JTJ/T0662 ASTM D 113. Suitable for measuring the ductility of asphalt and also for testing the elastic recovery test of modified asphalt2. Main features of asphalt elongation tester
