Asphalt Mixture Segregation Tester Conical Hopper

This asphalt mixture segregation tester (also known as asphalt mixture mixing characteristic tester) is specifically designed for determining the asphalt content segregation index, gradation segregation index, and mixing quality index of hot-mix (warm-mix) asphalt mixtures, to indirectly evaluate the mixing performance of asphalt mixtures themselves. It is a testing device for asphalt mixture mix design and construction quality control.

Test Principle: Load a specified mass (10kg±1kg) of asphalt mixture into the conical hopper. By controlling the sequential opening and closing of three switches (bottom, inner, outer), the mixture falls onto the material platform in layers. Asphalt content and gradation analysis are performed on each layer to calculate the segregation index and evaluate the mixing uniformity of the mixture.

Structure:

• Conical Hopper: Size φ400mm×φ80mm×500mm, inner opening diameter 140mm±5mm, outer opening diameter 220mm±5mm

• Three Switches: Bottom switch, inner switch, outer switch for controlled layered discharge of mixture

• Material Platform: Receives the layered falling mixture

• Rigid Frame: Provides stable support for the entire structure

Material & Process: Main body made of stainless steel for corrosion resistance and easy cleaning. Hopper equipped with rock wool insulation to reduce temperature loss of the mixture during testing.

Technical Parameters: Overall dimension 800×800×1600mm, net weight approx. 130kg.

Mainly used in highway engineering laboratories, asphalt mixture testing institutions, research universities, construction units, and more for segregation evaluation and mixing characteristic analysis of hot-mix and warm-mix asphalt mixtures.
