Road Consulting Services
Technical measurement and evaluation of road markings.
Overview
On-site retro-reflection and skid-resistance audits, applicator training, and DOT-grade quality reports — delivered by Candela field engineers.
We measure both diffuse and retro-reflection performance, and report retro-reflective values for dry and wet/rain conditions — the data municipalities and DOTs need for compliance and re-strike scheduling.

Two kinds of light.
One that matters at night.
We measure both — and we report retro-reflective values for dry and wet/rain conditions. The numbers municipalities and state DOTs need for compliance and re-strike scheduling.
Retro-reflection
Reflection from the light on the road markings under headlight illumination — returned directly toward the driver. The measurement that matters for night-time safety.
- Dry conditions (RL — daylight standard)
- Wet floor / rain conditions (RW — required for high-spec corridors)
