The Slurry Seal Loaded Wheel Sand Adhesion Tester is used to evaluate the asphalt content control and sand adhesion performance of slurry seal mixtures under repeated wheel loading. It helps determine whether excess asphalt exists in the mix and assesses surface stability and resistance to sand loss.

Slurry Seal Loaded Wheel Tester

Model:TD755-1

I.Product Introduction

This instrument is designed and manufactured in accordance with the Ministry of Transport of the People’s Republic of China industry standard JTG 3410-2025, specifically the requirements of “T0755-2025 Loaded Wheel Sand Adhesion Test for Slurry Mixture”.This testing apparatus is mainly used to determine whether excessive asphalt exists in emulsified asphalt slurry seal mixtures and to control the upper limit of asphalt content. The test results serve as an important basis for slurry seal mix design and construction quality control. In combination with the Wet Track Abrasion Test, it can be used to determine the optimum asphalt content of emulsified asphalt slurry seal mixtures.

Applicable or Reference Standards:ISSA TB 147A, EN 12274-5, ISSA TB 109.

III. Test Principle and Function

This equipment simulates the repeated rolling action of tires in actual road traffic to conduct loading tests on slurry seal specimens, thereby evaluating the mixture's resistance to sand adhesion and structural stability.

The main functions include:

Determining whether there is excessive asphalt in the mixture;

Controlling the upper limit of emulsified asphalt content;

Evaluating the surface's resistance to sand removal;

Analyzing the stability of the mixture under wheel loads;

Providing experimental basis for the optimal asphalt content.

IV. Product Features

1. Highly simulates actual traffic wheel loads

2. Stable with good test repeatability

3. Multiple mold sizes adaptable to different mix design ratios

4. Simple operation, stable and reliable data

5. Can be used in conjunction with wet tire wear tests to improve the completeness of the evaluatio
