The versatile Hveem-N-Beam Tester is a mid-range 60,000lbf (267kN) digital compression tester specially designed for Hveem asphalt stability testing, R-Value testing of soil samples, or (with attachments) recorded flexural testing of 6x6in (152x152mm) concrete beams. It can be adapted to suit many other tests including compressive strength of 6x12in soil cement cylinders, 3x6in grout or concrete cylinders, and for molding and strength of 2in, 3in, or 4in diameter bituminous concrete specimens.
The display shows live load, peak load, peak stress, and load rate with ±0.5% accuracy from 1%—100% of capacity in 0.44in digits. Load is displayed in lbf, N, or kgf, and memory is provided for up to 1,000 tests. USB interface allows transfer of data to PC. The 2.5in (64mm) stroke hydraulic ram has controller positions for rapid advance, metered advance at constant loading rate, hold, and retract. The two-stage hydraulic system is powered by a 1/2hp motor and safety features limit pressure to within load frame capacity, protect against piston overextension, and guard against flying specimen fragments. The rigid one-piece solid steel load frame comes with an 8in (203mm) diameter 1in (25mm) thick hardened steel lower platen and a 6.5in (165mm) diameter spherically-seated upper platen. Both are plated and scribed with concentric circles.
The MC-60 is set up for Hveem and R-Value testing as supplied. Upper platen shim locks are included to eliminate swivel action for mold compaction. The special Hveem valve is manually activated to drop load to 1,000lbf and automatically hold to ±20lbf as required in the test procedure. The 14x21.5in (356x546mm) WxH daylight opening (with platens) and included support stand are designed to permit easy placement and use of the Hveem stabilometer.
The MCA-4 Flexural Attachment and MCA-15 Spacer are required for testing 6x6in (152x152mm) beams of 12—30in (305—762mm) span in either center or third-point loading. Optional MCA-22 Data Collection and Reporting Software allows plotting of Modulus or Rupture (MOR) in lbf/in² vs. time and installs on the user's PC connected to the MC-60.
