FOOTWAYS. DESIGN AND MAINTENANCE GUIDE. PARTS 1 AND 2

This Design and Maintenance Guide is based upon the findings of research work commissioned by CSS and the Pavement Engineering Group of the Highways Agency and provides a practical field guide for engineers involved in the construction and maintenance of footways. Part 1 of the Guide covers footways constructed from common materials and subject to a range of pedestrian traffic and some overrun by vehicular traffic. Cycleways are also considered as these are frequently shared footways. Research has shown that designs are required for three categories of footway, the appropriate category being chosen according to the risk and type of vehicle overrun and on the amount of pedestrian usage. Guidance is given on selecting the most appropriate category and investigating the strength of the subgrade where a footway may be subject to vehicle overrun. The basic geometrical requirements are outlined and drainage works by Statutory Undertakers and environmental factors are discussed. Recommended construction thicknesses are given for each category of footway. These may vary with the wearing course material and bituminous materials, concrete or clay pavers, precast concrete flags and in-situ concrete are considered. Information is provided on construction details, including edge restraint, material specifications, compaction and skidding resistance requirements, tolerances and testing. Worked examples are included and a "notes for guidance" section provides additional information. Part 2 of the Guide covers the maintenance of footways constructed from common materials. Defects which are likely to be encountered by the maintenance engineer are described and illustrated. The mechanisms of material and structural behaviour, whereby these defects arise, are discussed. Advice is given on suitable treatment options, depending on the cause of the defect and the urgency of maintenance treatment. Both temporary and long-term treatments are described in some detail. As there are many different maintenance situations, and many possible solutions, flow charts are included, which outline the main decisions to be taken. Illustrated case studies show how maintenance solutions are chosen. (A) (This complete edition supercedes the edition published in 1996 containing Part 1 only).
