How to improve the performance of earth spur-roads



How to improve the performance of earth spur-roads



Lesnaya Promyshlennost' (11): 22-24



The modulus of deformation of the ground (as measured by the SoyuzDorNII impact-tester) is the criterion by which assessments are made in the USSR of the date when timber extraction can start on earth spur roads. A graph is presented showing the relationship between optimum dates for start, finish and duration of transport. Another graph shows the relationship between the number of passes of loaded lorries and the modulus of deformation.
