Sandy soil contains many geotechnical problems, including high permeability, less shear strength, sand dunes, and liquefaction. Therefore, it is necessary to stabilize the sandy improve its engineering properties, either through mechanical or chemical fixations. The one done by changing classification of mixing with other types soils additives in various gradients. While fixation related modifi...

subgrade soil stabilization is one of the primary and major processes in the construction of any highway; also environmental authorities are concerned about the growing amount of polyethylene (pet) bottles produced by household sectors. this research in order to study effect of adding recycled polyester fiber on soil engineering properties, especially shear strength and california bearing ratio...

The present study compares conventional pavement and perpetual in the case of ground-granulated blast-slag-stabilized black cotton soil. Ground-granulated blast slag (GGBS) can be used for over weak subgrade. We added to soil proportions 10 %, 20 30 40 %. After determining engineering properties GGBS, modified Proctor compaction California bearing ratio tests were performed. these values, six c...

Abstract The expansion and contraction of black cotton soil makes it difficult to build structures on it. behavior must be adapted make suitable for construction purposes. This research is an attempt evaluate the geotechnical characteristics by performing laboratory testing incorporating ground granulated blast furnace slag (GGBFS) (10, 20, 30 40%) polypropylene fiber (0.5, 1 1.5%) so as use co...

Red mud is a strong alkaline waste discharged from the process of alumina extraction, which harmful to environment and its utilization rate always low. One effective ways utilize red used as road subgrade material. In this paper, industrial wastes including mud, fly ash, slag, desulfurized gypsum are basic raw materials prepare filling materials. A series laboratory tests, such compaction test,...

Objectives: To determine the strength and swelling behavior of black cotton soil (expansive soil) using a shredded rubber tyre as an additive. Methods: Series unconfined compressive California Bearing Ratio (CBR) tests were carried out on mixed with 0%, 5%, 10%, 15% tyres, results compared untreated samples. The study also investigated influence characteristics by performing pressure test. Find...

Total metal concentrations in sediments from within Ensenada and El Sauzal Harbors are generally higher than at the mouths. Grain-size analyses suggested that this enrichment could be due to the presence of fine-grained sediments in the inner part of the harbors rather than to anthropogenic perturbations. The (Me/Al)sample ratios for Pb, Co, Ni and Fe were significantly higher for Ensenada Harb...

Tourmaline-bearing quartz veins and replacement deposits, commonly copperand gold-bearing, are found in unusual concentration in northwestern Nevada and adjacent northeastern California in Triassic and Jurassic arc rocks and in the Cretaceous plutons that intrude them. Mines and prospects that exploit the tourmaline-bearing deposits are found in a zone approximately 70 miles long and 50 miles w...

Abstract Geosynthetics are human made material used to reinforce soils improve the bearing capacity and permeability of soil, reducing soil settlement. application plays a vital role in highways constructions with no additive layers, such as cement concrete, asphalt or subgrade layer that affects unbounded layers. This paper presents geosynthetics tensional has been for reinforcement clayey soi...
