What Is ASTM E1710 Retroreflectance Pavement Marking?
ASTM E1710 is the standard test technique for assessing the retroreflective characteristics of horizontal pavement markings, such as traffic lines, utilizing a portable retroreflectometer. This method is intended for field measurement of pavement markings, but may also be used to measure the performance of materials on sample panels before placing the marking material in the field.
Applications and Benefits of ASTM E1710 Retroreflectance Pavement Marking Testing
Scope
ASTM E1710-18 focuses on determining the coefficient of retroreflected luminance (RL) of pavement markings under standardized geometry conditions. It ensures consistent and accurate field measurements.
The test evaluates:
- Retroreflectivity (RL) of pavement markings
- Nighttime visibility performance
- Effect of wear and aging
- Compliance with road safety standards
- Uniformity of markings
Applications
- Used by transportation agencies to verify compliance with performance requirements.
- Portable retroreflectometers allow on-site testing of pavement markings.
- Helps manufacturers and engineers assess different marking materials under real conditions before use.
- Retroreflectivity data from this method can be part of roadway safety assessments.
- Used to standardize performance benchmarks in contracts and technical specifications.
Benefits
- Helps ensure pavement markings are sufficiently visible at night or in low-light conditions.
- Provides a standardized method with defined geometry
- Designed for use with portable instruments that can be deployed directly on roads.
- Assists agencies and contractors in verifying retroreflective performance before and after installation.
- Higher measured retroreflectivity correlates with better visual recognition by drivers.

ASTM E1710 Retroreflectance Pavement Marking FAQs
ASTM E1710-18 is a standard test method used to measure retroreflectivity of pavement marking materials using a portable retroreflectometer with CEN-prescribed geometry under field conditions.
ASTM E1710-18 is important because it ensures pavement markings remain visible at night, helping drivers navigate safely and improving overall roadway safety and compliance with regulations.
ASTM E1710-18 measures light reflected from pavement markings at specified angles simulating vehicle headlights, determining how effectively markings return light to the driver’s eyes.
ASTM E1710-18 requires a portable retroreflectometer with defined geometry, calibration standards, and proper field setup to ensure accurate and repeatable measurements.
Results are reported as coefficient of retroreflection, typically in millicandelas per lux per square meter, indicating visibility performance and compliance with roadway safety standards.
ASTM E1710 measures the retro reflectivity of road pavement markings, such as traffic lines and road symbols, using a portable retro reflectometer. The instrument directs light onto the marking and measures the light reflected back toward the source at specified angles. Results are used to evaluate marking visibility and support road safety, particularly under night time driving conditions. Testing can be performed on road surfaces or sample panels before installation.
