ASPHALT BINDER TESTING-VDO
Vacuum Degassing Oven (VDO Touch)
ASTM D6521; AASHTO R28-06: EN 14769
The vacuum degassing oven (VDO touch) is used to precisely and accurately degas pressure-aged binder samples and is designed for rapid removal of entrapped air bubbles in asphalt specimens to the required 15 ±1.0kPa (25.5Hg). The net- work-ready 7in (178mm) touch-screen controller features easy menu-driven operation in multiple language options for fast programming of vac- uum, temperature values and soak times. The controller display indicates time, temperature, and current process stage, with alerts at the end of each test. When connected to a network with an Ethernet cable, the VDO Touch can be operated remotely via smart phones, tablets, or PC’s. USB Ports allow easy software upgrades.
The compact, table-top unit is constructed of stainless steel with a hinged lid to conserve space while allowing easy access to the stainless steel vacuum chamber. The oven holds up to (8) 4 oz. (114ml) or (4) 8 oz. (236ml) sample containers and features a self-contained, automatic vacuum system.
Temperatures in the VDO Touch vacuum cham- ber are measured by a platinum RTD probe with a range from ambient to 200°C with accu- racy to ±5°C. Soak and degassing times are both programmable up to 4,320 minutes. The rugged stainless steel cabinet, chamber and cover are easy to maintain, and the removable cover features a heat-resistant glass view- ing window for monitoring purposes The VDO includes: (4) 8 oz. (236ml) specimen contain- ers, specimen removal tool, stylus and clip. Dimensions: 24" x 16" x 12" (610 x 406 x 304mm).
ASPHALT BINDER TESTING-PAV, PBR
The PAV4 sample holder is a one-piece, solid device requiring no assembly and is easy to achieve an accurate level position with the lev- eling ring in the vessel. There is also room for a small bubble level between slots for verification purposes.
The PAV4 includes a network-ready modem, which provides connection to the internet, per- mitting the user to access the PAV3 with a mobile device or PC using a VNC viewer app program. VNC connection enables the user to connect, monitor, and control the PAV4 from a remote loca- tion. The PAV3 can be programmed with a custom IP address, so the number of PAV4s on a single network is essentially endless.
