ENVIRONMENTAL EFFECTS OF OPERATION AND MAINTENANCE METHODS

MILJOEEFFEKTER AV DRIFT OCH UNDERHAALL AV VAEGAR OCH GATOR

The project has involved a survey of tasks, directives and norms in the Nordic countries and a comparison among the countries with special regards of differences in prerequisites and methods. The tasks and methods have been divided into three main areas: 1) use of chemicals; 2) mechanical methods; and 3) direct environmental efforts. Within each of these areas a survey is made showing primary desired effects and known or suspected environmental effects of different operation and maintenance methods. The effects are looked upon both from the point of view of the road users and the outer environment. The main environmental problems concerned with road operation and maintenance are: 1) pollution of air, ground and ground water; 2) noise and vibrations; 3) damage to nature and cultural environment; and 4) consumption of natural resources. During winter, the use of salt on the roads is one of the major problems areas. The salt not only threatens the ground water close to the road and around snow heaps, but it also causes corrosion of bridges, increases corrosion of vehicles and traffic signs and causes soiling. In summer time the problems concern: 1) the use of machinery and material which affect the environment; 2) the use of gravel pits and stone quarries which implies permanent or "difficult to repair damages" to nature and consumption of natural resources; 3) surface work with asphalt machinery causing irritating noise; 4) use of chemicals, such as weed-killers and solvents. A survey is also done concerning the state of knowledge of the effects. It has also been possible to indicate important tasks of research. Among these we can mention: 1) an evaluation is needed of the experiments with salt solutions; 2) environmental aspects when using recycled pavement must be studied; 3) the development of pavements with lower noise levels must be supported. Finally the report also gives some estimations of the consequences, environmentally and cost wise, of alternative and more environmentally friendly operation and maintenance methods. (A)
