Structural design of hard surfacing

Summary

In 1987, the Department of Transport published a series of notes giving guidance on the design of new road pavements for highways, and these were based on research work reported in LR 1132, "The Structural Design of Bituminous Roads", and an analysis of surveys on the behaviour of flexible composite roads with cement bound roadways.

Report RR87 published by the same body reported recommendations on the thickness required for Concrete Roads . The new design approach assumed in the recommendations of looking much more closely at the selection of materials, and of predicting with more confidence the mean time before major repair, has found wide acceptance.

The BSI Committee charged with the preparation of standards for pavers identified the need for authoritative design guidance, and as a result published BS 7533 – "Structural Design of Pavements constructed with Clay or Concrete Block Pavers" in 1992. 

This symposium paper (83 Kb PDF) considers some of the revolutionary aspects of this document.
