Trl Road Note 31 5th Edition Road note 31 was first published in 1962 and revised in 1966 and 1977 to take account of advances in our understanding of the behaviour of road budding materials and their interaction in composite pavements. Road note 31 was first published in 1962 and revised in foundation design principles have been included to 1966, 1977 and 1993 to take account of advances in our encourage the use of various combinations of materials.
Overseas Road Note 31 Pdf Road note 31 was first published in 1962 and revised in 1966, 1977 and 1993 to take account of advances in our understanding of the behaviour of road building materials and their interactions in pavements. It is aimed at highway engineers and provides recommendations for designing roads expected to carry up to 30 million cumulative equivalent standard axles. the guide covers estimating traffic loads, determining subgrade strength, designing pavement layers, and providing a structural design catalogue.

Road note 31 outlines important aspects of flexible pavement design, including cbr requirements for base material and subgrade, as well as the necessity of a capping layer for weak soils. This guide provides comprehensive recommendations for the structural design of bitumen surfaced roads in tropical and subtropical climates, addressing material behavior, traffic loads, and environmental factors. A summary of the areas covered under these topics is provided as follows, but it is important to note that significant further content is covered in the 5th edition.
