JUSTIFYING THE DESIGNING METHODOLOGY OF THE EARTH WORKING PRODUCTIVITY DURING CONSTRUCTION OF THE FOREST ROADS
N A Turin
The management process of the agriculture and forest zones are carried out over vast territories, especially in the agricultural reclamation and areas or even in the planed agricultural land for rehabilitation. To carry out the problem of delivery the agricultural and forest yield and production required materials and equipment, it is necessary to planning for construction of more roads to achieve the goal of delivering the materials, equipment and yield on the time with the low cost and high quality. As a basic knowledge: the main material of the roadbed in such places (agriculture and forest) is the local soil, however the soil in some spots doesn’t show the quality of the using it to fill the filling stations. The main issue during road construction in forest and agriculture zones is the optimization of the soil moving process from the embankment spots to the filling spots. The earth moving optimization during the construction of the roads is a dual problem which contains; - optimization of the distribution of the soil along the constructed road (Designing the soil distribution) according to the following criteria: minimizing the moving distance and reduction of the using external materials – and the determining the sufficient amount of the technological machines according to their kinds, with the criteria of the available amount in the construction organization with the ability of renting specific technology.
