The author reports on the specialist contributions to the conference on the themes: road construction and traffic planning in hesse; hopes for cars and roads in the future; treatment of heavily trafficked wearing courses in France, their behaviour and practical experience; latest developments in the use of road tar in the construction of motorways in England. In the contributions to the main theme of the conference reports were made mainly on the possibilities of using tar, modified tar or bitumen-tar-mixes in the treatment of wearing courses. In England tarmacadam is now also permitted for the manufacture of basecourses and roadbases. The subject of the report of the working party was also the treatment of wearing surfaces, adhesive qualities and modified tars. In relation to adhesion it was shown that deficiencies in adhesion are only seldom admitted as the reason for damage. Pvc, polystyrene, polyurethene and epoxy resin are all considered as additives for modified tars. Bituminous mixes made with such additives have been used for the construction of wearing courses at airports, carriageways subject to deformation and for sealing reservoirs. /TRRL/
