Why are permeability, friction, and texture grouped together?

These tests collectively define surface functional performance: drainage capacity affects water evacuation, friction testing evaluates skid safety, and texture depth reflects macrotexture characteristics that influence both tire contact and wet-weather performance.

What is the difference between LS-SKD-P and BM-V?

Both are pendulum-based skid resistance instruments. LS-SKD-P is the classic manual-format friction tester, while BM-V is the intelligent digital version for users who prefer an integrated readout interface.

When should I choose LS-TEX-S instead of a friction tester?

Choose LS-TEX-S when you need macrotexture depth data rather than direct friction coefficient measurement. It is used to quantify pavement surface texture using the sand patch method.

ASPHALT MIX

Asphalt Permeability, Skid Resistance & Texture Testing

Surface functionality in asphalt pavements depends on the combined performance of drainage, friction, and macrotexture. Lithostek’s workflow in this section covers water permeability testing, pendulum-based skid resistance measurement, and sand patch texture depth assessment for road, runway, and wearing-course evaluation.

Selection Guide

Need Drainage Data?

Choose the LS-PRM-S to evaluate permeability performance of asphalt pavements or compacted asphalt mixture specimens.

Need Surface Friction?

Choose the LS-SKD-P for classic pendulum friction testing or the BM-V for a digital intelligent pendulum workflow.

Need Macrotexture Depth?

Choose the LS-TEX-S to measure pavement macrotexture using the standard sand patch method.
