Seasonal truck-load restrictions and road maintenance in countries with cold climate (الإنجليزية)

Some new member countries of the Bank are in regions where road structures are subject to seasonal freezing and thawing. Roads in these countries used to carry light vehicles during the spring thaw period without causing major pavement or structural damages. However, thin road overlays on frost-susceptible soils are subject to severe structural damage as vehicle weights increase. Vehicle weight restrictions can limit this damage. A sustainable solution to this problem is road rehabilitation using frost-resistant structural layers with high bearing capacity. This note also discusses current policies in France, the United States, and the Nordic countries pertaining to thaw restriction guidelines.
