Methodologies for the Use of Ground-Penetrating Radar in Road Condition Surveys - ME 91/16

This publication is aimed at the users of Ground-Penetrating Radar (GPR) in pavement condition surveys. It makes recommendations for the choice of GPR equipment as well as for the collecting, processing and interpreting of data.

CEDR Event on Energy Efficient Materials and Technologies for Durable and Sustainable Roads - November 10, 2016

The transition towards more sustainable road materials with lower energy demand introduces many challenges and difficulties in procurement, product specification and characterization of delivered pavements. The projects of this CEDR Call 2013 focus on tools and methods to solve these issues.

On 24th August 2015, about seventy delegates from fifteen countries gathered in BRRC’s auditorium at Sterrebeek to attend the final PERSUADE seminar (acronym of PoroElastic Road SUrface: an innovation to Avoid Damages to the Environment).

The objective of this six-year European research project (September 1, 2009 – August 31, 2015) led by BRRC was to develop a safe and durable poroelastic road surface, as a means to control road traffic noise.

A poroelastic road surface is composed of rubber granules (from recycled car tyres), small-sized stone aggregate and a number of additives, which are bound with an elastic synthetic resin (polyurethane). It contains no bitumen and must, therefore, not be confused with rubberized asphalt.

Earlier experiments had demonstrated that such a road surface can reduce road traffic noise by 7 to 12 dB. For comparison, a 4 m high noise screen has a noise-abating effect of about 8 dB.

However, durability was inadequate, especially for fretting and adhesion to the underlying layer. Further extensive research was necessary to improve those aspects and to find the answers to a number of pending questions.

About "Water and roads"

Road infrastructure should enable rainwater to be evacuated as soon as possible, so as to minimize disruption to traffic. This can be done in several ways: local infiltration, water-permeable road structure, or drainage by channels and gullies.

Today we are faced with climate change, resulting in irregular occurrence of extreme local peaks of precipitation.

Global warming is caused mainly by increased concentrations of greenhouse gases, in which CO2 emissions play a major part. Prompted by a number of developments such as the Kyoto protocol, road managers, road contractors and material producers try to reduce emissions. The transport sector is responsible for approximately 25 % of all greenhouse gas emissions, with the greater part being due to road transport. Energy consumption is also closely monitored in the road construction sector. Road managers and contractors have an interest in quantifying greenhouse gas emissions and energy consumption.

Choice of surfacing type

The right choice of structure and constituent layers is a primary concern to designers in both the private (engineering consultants, architects) and the public sector (technical departments of municipalities, provinces and regions) who have to make designs for new roads or for maintenance, renovation and adaptation works to existing infrastructure.
