Abstract. Roads are an integral part of the modern technological landscape, one of the most important elements of logistics and necessary condition for the functioning of social production. Roads today are impacted by the constant growth of traffic volumes, which increases the requirements to the quality of constructed subgrade, the stability and strength of this complex engineering structures. Sloping part of the road structure are one of the most vulnerable of its elements. Timely, high–quality and reliable strengthening of slopes of embankments and excavations of subgrade of roads, protecting them from erosion and other surface deformations plays an important role in modern society. Studies assessing the economic costs of strengthening of slopes of a highway planting of perennial lawns are held in the Perm district of the Perm region, on the slope of the roadbed reconstruction of automobile roads of General use of Federal value 1Р242 Perm – Ekaterinburg PC 73 + 00 – PK 74 + 00 (left). We study a mixture of “classic” and the Mixture of II with different seeding rates. Economic evaluation of actions for the planting of lawns on the slope of the subgrade of the road held in the collection of prices FER in base prices of 2001, taking into account the then–current period of inflation. The exclusion of perennial ryegrass from the composition of mixtures "classic" and replaced by meadow fescue increases the cost of seed was 1.7 %, while the quality of the turf surface does not change. The decrease in rate for every 20 kg/ha reduces the costs for the planting of lawns by 3.4–3.5 per cent.
Keywords: lawns, the slope of highway subgrade, seeding rate, grass mixture, economic evaluation of laying the lawn.
