DTS-30 (Pavetest)
The DTS-30 Dynamic Testing System is a servo-hydraulic testing machine utilizing digital control of a high performance servo valve to provide accurate loading wave shapes up to 100 Hz.
30 kN Servo-hydraulic actuator (100 mm Stroke)
2.2 kW Hydraulic Power Supply
HPS Pressure up to 210 bar
16 Channel Control
Load cell (± 30 kN)
100 mm actuator LVDT
Core Drill
Automated Core Drill (ACD) for fast, accurate cutting of cores from cylinders, prisms and slabs.
The ACD can produce cores of 12mm, 25mm, 38 mm, 50mm, 75mm, 100 mm and 150 mm diameter from Asphalt Shear-Box Compactor (ASC) prisms, Asphalt roller compactor (ARC) slabs and GYROTRONIC gyratory compactor or other SGC specimens (using the optional cylindrical specimen jig).
Ductility Tester (Basic)
The H-1068X is a three-speed machine designed for standard and force ductility tests. Ductility of formed asphalt/cement or semi-solid bitumen is determined by measuring the distance of elongation before reaching the breaking point of a briquette sample, which is pulled apart at a specific speed and temperature.
It includes a quality mechanical gear box. Speeds of 1/4, 1 or 5cm per minute are selected via lever shift on mechanical gear box. The unit is a bare-bones, economical ductility machine, which does NOT include a wrapped exterior or thermal-finned, stainless steel tubes for enhanced thermal transfer.
The APS is capable of cutting prismatic specimens up to 200mm high and a cutting length up to 500mm and cylindrical specimens up to 150 mm diameter.
Supports ASTM D113, ASTM D6084, AASHTO T51 standards
Ductility Tester (Temperature-controlled)
The H-1068B is a three-speed machine designed for Standard and Force Ductility tests. The machine builds on the H-1068X machine and adds a circulating temperature-control unit.
Solid-state thermostatically controlled bath and circulator maintain water temperature within a ± 0.18°F (± 0.1°C). The unit tests three briquettes simultaneously and its DC, direct-drive motor maintains constant speed, entirely vibration-free. Speeds of 1/4, 1 or 5cm per minute are selected via lever shift on mechanical gear box.
Conforms to ASTM D113, ASTM D6084, AASHTO T51 test standards
Asphalt Roller Compactor
Fully electro-mechanical system, that does not require any air source (compressor) or hydraulic pressure.
The sample slabs can be also cored or cut off to obtain cylinders and beams for run test, bending fatigue, indirect tensile, static and dynamic creep, stiffness and 4-point tests.
Multi Station Thermal Asphalt System (TSRST)
The Thermal Stress Restrained Specimen Test (TSRST) is used to determine the low temperature cracking susceptibility of asphalt concrete.
