Marshall Stability Tester for Asphalt Mixtures，This method is applicable to Marshall stability tests and immersion Marshall stability tests for asphalt mixture mix design or asphalt pavement construction quality inspection. The immersion Marshall stability test (and vacuum saturated Marshall te...

Viscosity testing standards vary from country to country. The following are viscosity testing standards from different countries.

Viscosity refers to the resistance a fluid exhibits to flow. When a fluid (gas or liquid) flows, if one part flows on top of another, it experiences resistance; this is the fluid's internal friction. To make the fluid flow, a linear force must be applied in the direction of flow to counteract t...

The main causes include substandard aggregate properties, unreasonable gradation selection, unreasonable structural design, construction technology, and the influence of traffic and climate environments.

Pavement rutting is an indentation formed when a pavement is subjected to repeated traffic loads, resulting in continuous micro-deformation in the longitudinal direction. This deformation accumulates and forms indentations, primarily manifesting as depressions within the wheel tracks and raised...

There are many different types of cracks. Cracks can be categorized as top-down, bottom-up, longitudinal, transverse, and blocky. The causes of cracks vary, and so do the solutions.

The "Testing Procedure for Asphalt and Asphalt Mixtures for Highway Engineering" (JTG 3410-2025) (hereinafter referred to as the "New Procedure") will come into effect on October 1, 2025, and the previous "Testing Procedure for Asphalt and Asphalt Mixtures for Highway Engineering" (TGE 20-2011)...

Road traffic reflective sheeting is the "invisible guardian" of nighttime driving safety, and its performance is directly related to road safety. GB/T 18833-2012, "Road Traffic Reflective Sheeting," is the core standard for domestic reflective sheeting products. It clearly defines product classif...

Full-automatic triaxial meter controller is an intelligent instrument using the latest contemporary technology. It is displayed and operated by computer software, which can accurately measure the circumferential pressure, counterpressure and hole pressure, and can precisely control the circumfe...

The microcomputer controlled stress-strain triaxial instrument can control the loading mode of force, stress, and strain in triaxial tests. This instrument is mainly used to measure the triaxial consolidation and shear compression tests of soil, in order to monitor changes in pore pressure. Acc...

Rock's elasticity, plasticity, brittleness, and toughness are different properties exhibited by rocks when subjected to stress.
