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.
Category: ASPHALT MIX
Available Systems
- LS-PRM-S: Asphalt Mixture Permeability Tester. Finely manufactured asphalt mixture permeability tester for determining the water permeability coefficient of asphalt pavements and laboratory-compacted asphalt specimens. Used to evaluate pavement drainage performance and support asphalt mixture design verification.
- LS-SKD-P: Skid Resistance & Friction Tester. Portable British Pendulum Tester for measuring skid resistance and friction coefficient of highways, urban roads, airport runways, and traffic marking coatings. Designed for stable laboratory or field testing with simple setup and minimal disruption to live traffic.
- BM-V: Intelligent Pendulum Friction Coefficient Tester. Intelligent pendulum friction coefficient tester for measuring skid resistance of highways, airport runways, and pavement marking coatings. The BM-V combines the proven British pendulum method with a digital readout interface for easier operation, stable data collection, and low-disruption field deployment.
- LS-TEX-S: Sand Patch Apparatus. Portable sand patch texture depth kit for measuring pavement macrotexture depth by the volumetric method. The kit uses a known volume of standard dry sand spread into a circular patch to calculate the average surface texture depth of road and runway pavements.
Frequently Asked Questions
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.
