Highway Pavements R&TCritical issues
Pavements are the backbone of transportation.Growing expectations of the highway user for smoother ride and reduced delay and disruption.

Long Life Pavements for the 21st Century
Critical issues“Just in time” delivery has increased from 10% in 1990 to over 60% in 2000.Of every dollar invested in highways more than 50 cents goes to pavements.

Long Life Pavements for the 21st Century
Critical issues
Most of the NHS pavements were constructed in the 1960-70’s.
