Advanced Automated Asphalt Saw, AUTOSAW II

Main Features:

• Touch screen CPU control allows for easy set-up including carriage speed and retraction sequence
• Intelligent system with adjustable limit switches allow for repetitive cuts with minimal carriage over travel saving time
• Protection cabinet with several automatic locking access doors to ensure unparalleled safety and clean operation in laboratory environments.
• Slab and prism of any shape and dimensions can be sawn without additional accessories (see table for maximum dimensions)
• Pneumatic clamping of prisms and cores
• Compressed air gun for cleaning specimens and sawing system
• Easy spacer system allows precise preparation of beams or cores
• Automatic advance and retraction of saw blade to home position

• Quick and easy specimen set-up

Asphalt Vibratory Compactor

The Asphalt Vibratory Compactor (AVC) is designed to form rectangular and cylindrical test specimens used for evaluating the susceptibility of permanent deformation (rutting), fatigue cracking, and moisture damage of asphalt mixes. The AVC compacts specimens at the same amplitude, same frequency, and same relative weight that a contractor experiences with a vibratory compactor on the roadway.

CORELOK

An innovative, non-nuclear method of determining SuperPave, Stone Matrix (SMA), and coarse mix asphalt air voids. CoreLok performs 5 standard lab tests:

• Bulk Specific Gravity
• Maximum Specific Gravity
• Aggregate Specific Gravity
• Porosity
• % Asphalt Content

The CoreLok® is a system for sealing asphalt samples so that the sample densities may be measured by water displacement methods. Samples are automatically sealed in specially designed puncture resistant polymer bags. Densities measured with the Corelok® system are highly reproducible and accurate. The results are not dependent on material type or sample shape. The GravitySuite™ PC software package calculates and manages your data for ease of operation. One Machine for All your Gravity Measurements of Asphalt and Aggregate. ASTM D6752, ASTM D6857, ASTM D7063. A fundamental density measurement. It does not require empirical calibrations. An accurate method for Bulk Specific Gravity measurement.
