the capillary viscometer acts like a precise temperature probe, capturing the secrets of flow at high temperatures; while the rotational viscometer acts like a director simulating construction, recreating the true state of asphalt during paving. Viscosity is not just data, but a silent oracle o...

Soil Proctor compaction test is a method of understanding the compaction characteristics of soil by compacting a soil sample with a hammer. This method involves hammering soil samples with different moisture contents using different compaction efforts (hammer weight × drop height × ...

Cone penetrating test apparatus is a kind of survey instrument widely used in designing and construction of building, power, traffic and harbor as well as original position test tool used in university for the use of scientific researching and designing groundwork.The apparatus through hydrauli...

This Asphalt Bending Beam Rheometer is used to determine the mechanical properties of asphalt bending failure at specified temperature and loading rate. Evaluate the deformation performance of asphalt.

The standard penetration test is an in-situ test that is coming under the category of penetrometer tests. The standard penetration tests are carried out in borehole. The test will measure the resistance of the soil strata to the penetration undergone. A penetration emphirical correlation is der...

In the field using a calibration equipment, rotary torque load shall be prepared in advance, can use weight, sand, stone and other materials, and was in the following order: The instrument base is installed on the casing, fixed properly, put on the transmission parts.

Vane Shear tester is used for on-site measurement of the saturated soft clay and natural shear strength of the instrument. High sensitivity for soft clay, earth sample preparation since the disturbance, the impact strength is very obvious, the use of the instrument can get closer to the actual ...

Over long-term use, asphalt pavements develop defects due to the combined effects of vehicle loads and the external environment, resulting in loss of their original functionality. Asphalt pavement defects can be broadly categorized into two types: surface functional defects and pavement structu...

Point load strength testing can be performed on irregular rock blocks and cores. This portable equipment is suitable for rapid on-site testing, offering low cost and short testing time. Uniaxial compressive strength directly reflects the rock's ability to resist uniaxial pressure and is a core ...

Asphalt mixtures undergo thermal aging during the mixing, paving, and compaction processes. During service, asphalt pavements are exposed to various factors such as sunlight, temperature, oxygen, ultraviolet radiation, rainwater, and groundwater, leading to long-term aging. Aging results in pav...

ZK-2000 Air generator is an air generator with stable pressure and pure air output. This instrument can be used with any type of evaporative light scattering analyzer or gas chromatograph produced by any manufacturer. It is an ideal upgraded product to replace the high-pressure air bottle suppl...
