This series of testing machine takes hydraulic pressure as power, USES electro-hydraulic servo control technology to test the compressive mechanical properties of cement, mortar, brick, concrete and other building materials, and shows the loading force value, loading speed and loading curve. Test data is processed, stored and printed automatically.

The Pavetest BBR is a thermoelectrically-cooled bending beam rheometer for testing flexural creep of asphalt binders from ambient to –40 °C (± 0.03 °C). The load is applied by a miniature servo-controlled actuator capable of applying up to +/- 10N and loading frequency from static to 25Hz, without the need for compressed air supply. The use of servo-control eliminates the need for frequent calibration and repeated adjustment of air bearing pressures. Just enter the required load and the servo-controlled actuator will apply and maintain the requested load with incredible precision. The temperature is controlled very precisely using a temperature controller mounted on the front of the machine. The user can set the bath temperature using the controller or via the software. The BBR is supplied complete with a suitable chiller to ensure a temperature range between ambient and -40°C.

Dynamic Cone Penetrometers (DCP) provides quick field determinations of soil shear strengths at depths up to 6ft (1.8m), with optional extensions. This accurate and portable field equipment measures soil properties that can be related to CBR or Resilient Modulus laboratory values. Original design by the United States Army Corps of Engineers meets ASTM requirements. The DCP bridges the gap between laboratory pavement design and construction quality assurance.

The Los Angeles Abrasion Machine is used for determination of the aggregates resistance to fragmentation. The machine consists of an electronic control unit and a rolled steel drum having an inside diameter of 711 mm and internal length of 508 mm. The drum is rotated at a speed of 30-33 r.p.m. The machine is equipped with an automatic counter, when the preset revolution count is reached, the machine will stop automatically. The drum is equipped with an interlock device which allows the operator to lock the drum into position for easy loading/unloading of the sample.

The integrated rebar detector is a portable non-destructive testing instrument, which can be used to test the construction quality of reinforced concrete structures. It can measure the position of rebars on the concrete surface, detect the thickness of the steel protective layer and the diameter of the rebar. Compact size, light weight, easy to carry, wireless cloud transmission function, laser，precise positioning of steel bar position;Thickness detection mode is intuitive, showing thickness and steel spacing at the same time. Waveform scanning mode shows the distribution of reinforcing bars intuitively, and it is more intuitive to detect and analyze dense reinforcing bars. The waveform scanning mode also shows the thickness and spacing of the rebar protective layer. It can detect the middle position of the two reinforcing bars, The instrument automatically stores the calibration value, realizes fast measurement and avoids the trouble of each calibration.

The density of asphalt pavement is directly proportional to the dielectric constant of the measured material.The gtj-2701 USES an innovative, spiral-shaped magnetic field detector to test the dielectric constant in the presence of a magnetic field generated by the sensor plate. The electronic components of the gtj-2701 convert the field signal into a material density reading displayed on the screen.Once the instrument is calibrated, the density can be read at once.
