How to detect asphalt msds?Inspection methods: sample inspection, visual inspection, witness test, on-site inspection, etc.

Test scope: including performance test, component analysis, biological test, formula test, etc.

Main test items: penetration (viscosity) of asphalt: viscosity of viscous petroleum asphalt is expressed by penetration value. Viscosity is the ability to resist deformation under external force.

Bitumen ductility (plasticity): plasticity refers to the ability of searching for the deformation without damage of petroleum asphalt under external force. Asphalt softening point (temperature stability): temperature stability refers to the performance of viscosity and plasticity of petroleum asphalt changing with temperature rise and fall.

Solubility, density, evaporation loss, film oven test, brittleness point, wax content, penetration, kinematic viscosity, freezing point, softening point, sag, asphaltene content, composition analysis, etc.

Test indicators: generally adopt national standards and industrial standards, and can also refer to ASTM, TP, ISO, UOP, JIS and EN indicators.


Test method for asphalt content of asphalt mixture

1. Ray method: it is applicable to the detection and use of asphalt dosage during the construction of hot-mix and hot-paved asphalt mixture pavement to quickly evaluate the product quality of the mixing plant.

2. Centrifugal separation method: this method is applicable to the detection of asphalt dosage during the construction of hot-mixed and hot-paved asphalt mixture pavement to evaluate the product quality of the mixing plant. This method is also applicable to the detection of asphalt content of asphalt mixture during the investigation of old roads. The asphalt solution extracted by this method can be used for recycling asphalt to evaluate the aging properties of asphalt.
