    Rock Point Load Tester, Rock Point Load Testing Instrument, Model STDZ-3

    Rock Point Load Tester, Rock Point Load Testing Instrument, Model STDZ-3

    The rock point‑load tester is an instrument used for conducting point‑load tests on rocks and determining the point‑load strength index. Based on this index, it is possible to calculate the uniaxial compressive strength of the rock, assess its anisotropy (i.e., the ratio of the minimum point‑load strength to the maximum), identify weathering zones, estimate drilling rates, classify rocks, and more.

    Pavement Smoothness Tester, Continuous Eight-Wheel Highway Smoothness Meter, Model LXBP-6

    Pavement Smoothness Tester, Continuous Eight-Wheel Highway Smoothness Meter, Model LXBP-6

    The continuous eight‑wheel road roughness meter is an instrument primarily used for assessing pavement smoothness. It features continuous measurement, automatic data processing, high accuracy, rapid measurement, and the ability to display and print the standard deviation of pavement smoothness. It is suitable for construction inspection, as‑built acceptance, and routine pavement maintenance, serving as a critical data indicator for highways, urban roads, airport runways, and other pavement projects. However, it is not appropriate for use on pavements with numerous potholes or severe distress.

    HZ-20 Type Trailer-Mounted Concrete Core Drilling Machine; Vehicle‑Mounted and Trailer‑Mounted Pavement Drilling Machine

    HZ-20 Type Trailer-Mounted Concrete Core Drilling Machine; Vehicle‑Mounted and Trailer‑Mounted Pavement Drilling Machine

    The HZ-20 trailer‑mounted concrete core drilling machine employs high‑speed cutting technology and is compatible with thin‑walled diamond drill bits. It is widely used for drilling and coring in engineering construction, municipal projects, equipment installation, and building quality inspection. It is employed to extract cores from concrete, asphalt pavements, and limestone foundations at highways, airports, ports, dams, and other sites for compressive and flexural strength testing, as well as for drilling anchor bolt holes during the installation of heavy machinery and equipment, and for drilling openings to install bridge handrails and traffic safety guardrails.

    ZBBM-III Pendulum Friction Tester, Pendulum Tester, Pavement Pendulum Tester – In Stock

    ZBBM-III Pendulum Friction Tester, Pendulum Tester, Pavement Pendulum Tester – In Stock

    The pendulum tester is a dynamic pendulum‑impact instrument. It was developed based on the fundamental principle that “the loss of potential energy of the pendulum equals the work done to overcome friction between the rubber pad mounted at the end of the pendulum arm and the road surface as it slides along it.”

    Road Marking Retroreflectance Meter

    Road Marking Retroreflectance Meter

    The STT-301D pavement marking retroreflectance meter is an instrument designed to measure the reflective performance of road markings. Its primary measurement parameter is the retroreflectance coefficient (also known as relative luminance), expressed in mcd·lx⁻¹·m⁻². This device is easy to operate, delivers reliable results, and is suitable for both laboratory settings and field measurements. It is an essential tool for construction firms, quality‑control agencies, supervisory bodies, and other relevant organizations engaged in assessing the retroreflective properties of pavement markings.
