Despatch Laboratory Ovens

There is no better way to complement the quality of the Troxler Superpave™ compactor than by using the best quality laboratory heating oven. Ovens from Despatch Industries will meet or exceed your expectations for a busy asphalt design and testing lab.

Since 1902, Despatch Industries has produced heat process equipment for a variety of industries, including ovens for asphalt testing. The LBB series from Despatch is designed specifically for Superpave™ mixtures and is now available through Troxler.

I-FIT (IL - Flexibility Index Tester)

Mechanical Configuration

The Troxler I-FIT (Illinois - Flexibility Index Tester) machine is completely contained on a rolling portable test frame that is approximately 31.5" L x 20" D x 34" H. The fixture is designed to apply load to a Semi-Circular Beam (SCB) specimen through a pivoting head and roller bearing pins. The system is designed to meet the most current standard for TP105 Illinois.

Servo Hydraulic Actuator

The system includes a 4500lbf actuator with low friction seals. It utilizes closed loop feedback from the load cell and magneto restrictive position sensors for stroke and load line displacement (LLD).

Load Line Displacement Measurement

The LLD position sensor utilizes a non-contacting method to measures displacement of SCB specimen at the loading head.

Controls and Software

It includes a custom program for I-FIT test operation. Every test has a text data file created for easy to use post processing as well as printouts from the test during operation. In addition, a Multi-Test Language (MTL) compiler is provided to allow the user to create custom programs or modify custom programs and store as a callable application.

Features

• Accuracy - patented 2 CUDT system
• Immediately prints and plots test summary
• Includes ICT software for determining Flexibility Index (FI)
• Three second runtime
• Simple sample preparation
• Most advanced hydraulics on the market

DCT-OT (Disk-shaped Compact Tension)

Features

The Troxler Disk-shaped Compact Tension and Texas Overlay Test Machine (DCT - OT) offers the following features.

• Test results are printed and plotted immediately. There is no prost processing.
• The DCT is completely contained on a rolling portable test frame that is designed to carry the load through the conventional pins used by DCT to load the specimen. 
• It comes with a Texas Overlay test fixture and a copper tub.
• The system is designed to meet the most current AASHTO D7313 standard.
• A built-in insulated chamber in a chest style configuration with a flip top eliminates immediate air exchange when opening the chamber to change a specimen.
• The system includes a 4500 lb force actuator with low friction seals and a magneto restrictive position sensor that is controlled by a proportional valve for closing the loop to control load, position, or strain.

IDEAL Plus

The IDEAL Plus offers precise rate control for testing. 

Machine Configuration

• Stand-alone cart provides dedicated work space and allows hassle-free portability
• Re-configuration spring rollers for running various SCB tests (I-FIT, LSU, SCB, etc.)
• Standard 13,000lbf capacity for running IDEAL and TSR tests
• High performance valve option for dynamic tests and precise load control

Load Line Displacement (LLD) Measurement

• No need to worry about mounting an LVDT or crushing one by running over LVDT travel limits
• Optional patent pending LLD average measurement and control gives the highest confidence in test rate control - averages the displacement on the left and right side of the fixture

Testquip Saws

Customized for quick and accurate sample cutting!

Brick Saw

The Testquip Tile Saw is customized with a 16" blade for 6" cuts. Once the specimen is inserted, simply slide the table left or right in the preconfigured thickness offsets (50mm and 62 mm default).

Tile Saw

The Testquip Brick Saw features a 0.050" thick 10" blade to meet test standard notch cut thickness requirements. A custom spring clamp fixture is mounted to the back of the table for quick and secure sample loading. It includes spacer block to allow cutting SCB (15mm default) and DCT specimen notch cuts without adjusting the blade.
