The Tri-Unit Asphalt Mixture Permeability Tester is a high-precision testing instrument designed specifically for laboratories, primarily used to determine the permeability of hydraulic asphalt concrete. Equipped with three independent testing units, this device can simultaneously test multiple samples, improving experimental efficiency.

Triple-Unit Bituminous Mixtures Permeability Tester

Model:TDZR-5326-III

I.Product Introduction

The Triple-Unit Bituminous Mixtures Permeability Tester is designed to determine the permeability coefficient of asphalt concrete in accordance with DL/T 5362-2006(Hydraulic Asphalt Concrete Test Procedure),while also referencing international standards such as ASTM D5084(Standard Test Methods for Measurement of Hydraulic Conductivity of Saturated Porous Materials Using a Flexible Wall Permeameter)and EN 12697-19(Bituminous Mixtures–Test Methods–Part 19:Permeability of Specimens).The constant head test is suitable for specimens with a large permeability coefficient,while the variable head test is suitable for specimens with a smaller permeability coefficient.

Scope of Application:Concrete

1.Primarily used for testing the permeability of hydraulic asphalt concrete.

2.Suitable for research institutions,engineering testing organizations,construction companies,etc.,for evaluating the impermeability of asphalt mixtures.

II.Test Methods

Constant Head Test:Applicable to high-permeability specimens,the permeability coefficient is calculated by measuring the seepage rate under a stable head.

Variable Head Test:Applicable to low-permeability specimens,the permeability coefficient is calculated by observing changes in head.

III.Product Features

Triple-unit design:Allows for simultaneous testing of three specimens,improving testing efficiency.

Easy operation:Equipped with digital display and automatic control functions,reducing human error.
