Universal asphalt and concrete saw, MULTISAW

A unique machine specifically designed for laboratory use to precisely cut Asphalt, Concrete and Rock samples

Main features
  • Specifically designed to fulfill the stringent requirements of the relevant 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 sawn 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 edge chipping of asphalt samples
  • Easy spacer system allows precise preparation of beams or cores
  • Manual advance and retraction of saw blade to home position
  • Motor mounted on twin chrome-plated steel rails with sealed bearings
  • Also suitable for concrete and rock samples
General description
General description
The cutting machines proposed in the market are normally standard saws for field use in the building industry, modified to clamp and to cut samples. They do not assure the rigidity and stability to obtain precisely specimens for laboratory use. For this reason we have designed and produced specifically designed Asphalt saws to fulfill the stringent 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, water pump for cooling the blade. Completed with the suitable accessory, it can be used to cut also 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 accurate cutting of beams for asphalt prisms to be used for 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 diameter from 100 to 150 mm, and 200 mm dia. to be quickly and accurately cut to different lengths from 10 to 300 mm.
