عنوان انگلیسی Effect of Hydraulic Seeding Treatments on of Road Cut Slope
چکیده انگلیسی مقاله Aims: In the present study, effect of different hydro seed binder combinations were evaluated on stability clay soil cut slope of road in the campus of Gorgan University of Agricultural Sciences and Natural Resources, Iran. Materials & Methods: The hydro-seed treatments were classified as A (5L m-2 water, 50g m-2 Festuca arundinacea L., 40g m-2 polyacrylamide tackifier, 30g m-2 starter fertilizer and 20g m-2 super absorbent polymer), B (5L m-2 water, 70g m-2 Festuca arundinacea L., 50g m-2 polyacrylamide tackifier, 40g m-2 starter fertilizer and 30g m-2 super absorbent polymer) and C (5L m-2 water, 90g m-2 Festuca arundinacea L., 60g m-2 polyacrylamide tackifier, 50g m-2 starter fertilizer and 40g m-2 super absorbent polymer). Then mean weight diameter, aggregate stability, liquid limit, friction angle and, soil cohesion indices experiments in wet and dry conditions conducted in three replications for each treatment. Findings: Results showed that the maximum value of MWDwet (0.91mm), MWDdry (5.4mm), aggregate stability (88%), liquid limit (48%), plastic limit (35%), friction angle (44.9 degree) and soil cohesion (13.5kPa) obtained by application of hydro-seed C. Minimum percentage of aggregate destruction (38%) and plastic index (13%) obtained in results of hydro-seed C application. Conclusion: The application of hydraulic seeding treatments improved the structural stability, plastic index and shear strength of the soil. Future research in this subject requires to perform in the field. This study will eventually be used in the implementation section.
