ABSTRACT
This chapter deals with external hard surfaces, including private roads for light traffic. Certain notes also apply to public highways. Owing to the wide range of functions and materials that are included, it is difficult to avoid repetition, unless cross-references are included. These have been kept to a minimum as it is realized how maddening they can be, and the chapter has been organized thus:
1. notes on the functions of paved surfaces 2. list of highway engineering terms 3. notes on roads and pavements primarily intended for wheeled traffic 4. general design problems common to all paving structures 5. descriptions of individual types of pavement, by type rather than function. This means
that surfaces intended for vehicular or pedestrian traffic are described together. Since the problems involved are often common to both, and since many pedestrian spaces are also intended to take the occasional wheeled vehicle, this seems the clearest division to make
6. problems of detail common to all types of pavement.
