Standard: EN 14769, ASTM D6521, AASHTO R28
Product Description
The NL PavePro Vacuum Degassing Oven (VDO) utilizes advanced vacuum generator technology to remove air bubbles from asphalt binders and materials following pressure aging. This system ensures sample integrity for subsequent testing by maintaining a precise negative pressure environment while monitoring temperature and pressure in real-time.
Designed for efficiency and durability, the unit features a 7-inch touchscreen for curve tracking and a glass viewing window for process observation. Housed in an easy-to-clean stainless steel cabinet, it supports automatic data printing and USB export, ensuring full compliance with international standards.
