FOURTEENTH WORLD CONGRESS - PRAGUE 1971 - COMMITTEE FOR LOW COST ROADS - REPORT OF THE COMMITTEE AND GENERAL REPORT ON QUESTION 7: LIGHTLY-TRAFFICKED ROADS

QUATORZIEME CONGRES MONDIAL - PRAGUE 1971 - COMITE DES ROUTES ECONOMIQUES - RAPPORT DU COMITE ET RAPPORT GENERAL SUR LA QUESTION VII ROUTES A FAIBLE CIRCULATION

This report summarizes replies obtained from 18 countries, it comprises nine chapters. Chapter 3 deals with the stabilization of pavements in tropical and subtropical countries. It is mainly concerned with the technical arrangements to be made for the design and construction of pavements stabilized with cement, lime or bitumen. Chapter 4 considers the use of non-traditional materials for the construction of pavements, special binders (lime, slag, fly-ash, emulsion, fillers), laboratory tests, and in-situ tests for studying the performance of non-traditional materials. Chapter 5 deals with the behaviour of pavements under traffic and their strengthening under subtropical and tropical conditions. It shows the need for a detailed knowledge of traffic characteristics, the influence of the climate and that of the nature of the materials. Visual observations and deflection measurements under load are used to evaluate the need for strengthening. The subject of chapter 6 is corrosion prevention in subtropical and tropical countries and emphasis is laid on the wide variety of means of preventing erosion. Chapter 7 studies the influence of secondary roads on the economic and social development. Chapter 8 examines the maintenance costs of roads with a daily traffic volume less than 100 vehicles. In chapter 9 the problems of the total cost of the transport of 1 tonne of freight to the user as a function of the type of vehicles is discussed, but there exist too few data on transport costs as a function of vehicle axle load. The number of the covering abstract of the conference is irrd abstract no. 100978. /TRRL/
