Standard Asphalt Viscosity,The time required for a specified amount of asphalt sample to flow out of a specified volume through a specified orifice in a specific sample cup at a specified temperature.

The Asphalt Bending Beam Rheometer (BBR) is a core instrument used to evaluate the low-temperature performance of asphalt materials.

Soil mechanics is similar to the study of all other material mechanics, specifically the deformation and failure behavior of geotechnical materials under certain loads. Soil is a loose medium with a certain amount of porosity, and soil particles often exhibit both cohesion and the ability to sl...

This method uses Saybolt viscometer to measure the conditional viscosity of viscous petroleum asphalt, emulsified asphalt, liquid petroleum asphalt, etc. at higher temperatures, and is used to determine the construction temperature of asphalt. Under normal circumstances, the measurement tempera...

Industrial burn-in ovens are developed for dynamic and fixed burn-in of integrated circuits and other digital tools consisting of laser diodes. Typical burn-in equipment sizes range from under 30 cubic feet to over 0.85 cubic feet (3 cubic meters) with either air or nitrogen units. Operating te...

The rock point load tester is a portable test equipment used to measure the point load strength and anisotropy of rocks. It is suitable for coal mining, geology, transportation and other fields. The instrument adopts a precision guide structure and hydraulic loading system with a maximum workin...

In the study of residual strength of soil, the ring shear apparatus is a better test instrument. Compared with the direct shear apparatus and the single shear apparatus, the ring shear apparatus has the advantages of being able to achieve larger shear displacement, keeping the shear area unchan...

DCP was developed by the Transport Research Laboratory (TRL) in the UK and weighs 20kg. It mainly includes an 8kg drop weight with a drop height of 575mm, a penetration rod, a ruler, and a 20mm diameter cone tip connected to the end of the penetration rod.

Data collection and analysis in the Field Vane Shear Test are vital for accurately determining the undrained shear strength of soil. By following standardized procedures for both manual and digital data collection, ensuring data integrity, and performing thorough analysis, geotechnical engineer...

The field cross-plate shear test is a key tool in geotechnical engineering that provides valuable data on the undrained shear strength of cohesive soils. Its ability to accurately measure the undrained shear strength of soft clays makes it an indispensable tool for engineers and researchers.

The Marshall tester is a test to determine the optimal asphalt-to-rock ratio of asphalt mixture. The test process is to compact the specimen under specified temperature and humidity conditions, measure the stability and flow value of the asphalt mixture, and after a series of calculations, draw...

The asphalt Marshall test is used to detect the performance indicators of asphalt mixtures, focusing on three parameters: stability, flow value, and void ratio. These three indicators directly affect the high-temperature deformation resistance, low-temperature crack resistance and durability of...
