General Information
- Abstract
This document specifies a test method for determining the particle loss of porous asphalt mixtures. Particle loss is assessed by the loss of mass of porous asphalt samples after turns in the Los Angeles machine. This test enables the estimation of the abrasion resistance of porous asphalt. The test applies to laboratory compacted cylindrical specimens of porous asphalt mixtures, the upper sieve size of which does not exceed 22,4 mm. It does not reflect the abrasive effect by studded tyres.

Overview
FprEN 12697-17: Bituminous mixtures - Test methods - Part 17: Particle loss of porous asphalt specimens is a European draft standard developed by CEN (European Committee for Standardization). This standard specifies a laboratory test method for evaluating the particle loss of porous asphalt mixtures. Particle loss is determined by measuring the mass loss of compacted cylindrical porous asphalt specimens after they undergo a tumbling process in a Los Angeles machine. The procedure is designed to estimate the abrasion resistance of porous asphalt, an important factor in assessing the durability and long-term performance of asphalt surfacing for road construction.
The standard applies to laboratory-compacted porous asphalt mixtures with a maximum aggregate size of 22.4 mm. It is relevant for quality control, product development, and performance assessment of porous asphalt, and does not assess the specific abrasive effect of studded tyres.
Key Topics
- Abrasion resistance testing: Describes a repeatable laboratory method for quantifying the resistance of porous asphalt mixtures to particle loss due to mechanical action.
- Los Angeles machine use: Specifies the use of a standardized Los Angeles machine, with controlled rotational speed and without abrasive balls, to simulate real-world wear.
- Sample requirements: Defines preparation, compaction method, specimen dimensions, density assessment, and conditioning prior to testing.
- Measurement and calculation: Involves pre- and post-test weighing of specimens to compute mass loss as a percentage, representing particle loss.
- Effect of water: An informative annex includes procedures for assessing the impact of water conditioning on particle loss, supporting evaluation under different environmental exposures.
- Repeatability and precision: Provides repeatability and reproducibility data to ensure consistent results across laboratories.
Applications
FprEN 12697-17 offers practical benefits for various stakeholders in the road construction industry:
- Quality assurance: Helps manufacturers and contractors validate the abrasion resistance of porous asphalt mixtures before installation, ensuring compliance with project specifications.
- Material optimization: Assists researchers and mix designers in comparing different bituminous formulations or aggregates to develop more durable, water-resistant porous asphalt surfaces.
- Performance prediction: Provides objective data for predicting the lifespan and maintenance needs of porous asphalt pavements under typical mechanical stress.
- Regulatory compliance: Supports national authorities and testing laboratories in aligning with harmonized European standards for construction materials.
- Environmental considerations: The annexed water conditioning test procedure enables the evaluation of how water exposure may accelerate particle loss in porous asphalt, informing decisions on material suitability in climate-exposed regions.
