Standard cutting machines in the market are standard saws for field use in the building industry. They do not assure the rigidity and stability to obtain precisely specimens for laboratory use. For this reason, we have designed and produced the specific requirements of the relevant Standards and consequently of the Research and Central laboratories.
Multisaw is a universal sawing system for fast, accurate cutting of beams from prisms and for trimming cylinders. An easy-to-use spacer system sets the specimen position and allows beams or cores to be cut without the need for measurement. The saw blade advances and retracts to the home position by a user-friendly hand wheel.
The Multisaw includes the multislab jig, complete with table and manual clamping device for slabs. Cores at the desired length. It can be fitted with 650 mm dia. blade with a maximum cutting depth of 200 mm and prism length of 500 mm (extendable to 700 mm, on request).
The Multisaw allows an easy-to-use sawing system for the Four-Point Bending Beam tests, Two Point Bending Beam tests, TSRST, Texas Overlay Test, Prall Test, Semi-Circular Bend Test, Wheel Tracking Tests with large and small devices, or any concrete beam or cylinder. The system allows cylindrical cores with diameters from 100 to 150 mm, and 200 mm dia. to be quickly and accurately cut to different lengths from 10 to 300 mm.
The Multisawcan be used as part of your Superpave performance based testing program.
- Standards in terms of precision, planarity and perpendicularity of the specimens.
- High rigidity and stability
- Slab and prism of any shape and dimensions can be without additional accessories (see table for maximum dimensions)
- Jig for round cores, from 100 to 150 mm and for 200 mm dia, length up to 300 mm
- Unique clamping mechanism for cylindrical specimens minimizes specimen damage. Use of a sacrificial PVC tube produces a superior finish and minimizes the edge of the chipping of asphalt samples
- Easy spacer system allows precise preparation of beams or cores
- Saw blade to home position
- Motor mounted on twin chrome-plated steel rails with sealed bearings
- Also suitable for concrete and rock samples
