Vertical & Horizontal Signage

Along with checks on materials and on-site monitoring Article 700 of Order PG-3 (dating from 2000) on signage, ground lighting and guard rails for roads requires the back-reflection, luminance factor and slip resistance of road markings to be maintained within certain limits over time.

The first step is to select the right materials, based on criteria such as:

• Location of road markings
• Traffic-free zone
• Right-hand shoulder, 2-lane road
• Left-hand shoulder, 2-lane road
• Shoulder, single-lane road
• Central axis
• Special strips
• Crossings, symbols
• Pavement texturing
• Low
• Medium
• High
• Type of highway & lane width
• ADT
• = 5,000
• > 20,000

It must be assured that all marks maintain the proper back-reflection, luminance factor and SRT throughout their warranty period.  To that end, Euroconsult Nuevas Tecnologías has portable back-reflection meters, a spectrophotocolorimeter and an SRT pendulum. We also have three Ecodyn units capable of taking measurements at normal traffic speeds to assess the back-reflection of marks in service
