Dive Brief:

• The World Road Association has issued its 2013 guide to reducing road noise from a range of pavement types.
• The guide, Quiet Pavement Technologies, uses information contributed by highway engineers globally.
• A range of asphalt mixes and Portland cement techniques are addressed in terms of acoustics noise, durability, safety and structural performance.

Dive Insight:

The World Road Association, also known by the acronym of its French name at its founding, PIARC, has national committees in 37 countries that it draws on for what highway engineers and builders have learned. The report looked at ways to quiet roads after construction and ways to plan for quieter pavements ahead of building, and it says that it expects planning for reduced noise to be "the most cost–effective and efficient approach."
