For various construction purposes soils may be improved through the addition of chemical binders. These chemical additives range from waste products to manufactured materials and include mainly lime, fly ash, Portland cement and cement kiln dust (CKD). They bind soil particles together in order to make the soil matrix more water and pressure resistant. Soil binder has two functions: erosion control and soil stabilization. The success of common soil binder applications varies significantly depending on the local conditions and use of stabilized soil. Lime in certain forms can be used as soil binder. These forms are quicklime, hydrated lime and…

When present, dust disturbs everyday life and work by reducing visibility, by depositing on various surfaces and by irritating nose, throat and skin. Moreover, dust has sincere influence on health through direct contact or through dispersion in air, soil and water bodies. Sources of dust are mining and construction processes, driving and operating on unpaved roads, etc. Therefore, there are different types of dust depending on the source. For example, coal dust is quite hazardous because it is a leading cause of black lung disease among miners. On the other side, dust produced from sand, gravel and stone processing causes…

Stabilized soil is to serve under various local conditions, such as hot or cold weather, and dry or wet periods. The problems with non-treated soils are: deformations created under the loads of vehicles, machines, buildings, etc. shrinking and swelling due to higher or lower water saturation water permeability which leads to various forms of deformations, from small ones such as small cracks, to large ones such as erosion Methods of soil stabilization There are various methods for stabilization of soil and they can be broadly divided into physical and chemical ones. Physical methods involve physical processes to improve soil properties….

Bitumen is a by-product of the fractional distillation of crude oil, but is also found in natural deposits. It has water-proofing and adhesive properties and thus has been used for thousands of years. Bitumen is widely used in roofing, road and pavement applications. However, it has significant drawbacks. Bitumen is brittle under low temperature and becomes soft under high temperature conditions. If used for pavement, likely results during time are dust, potholes, rutting, corrugation and other surface degradations caused by heavy traffic or extreme temperature. The road deteriorations lead to unsafe traffic conditions, decreased useful life of vehicles and higher…

Dust affects almost all parts of life and work as it influences human health, environment, traffic and work by reducing visibility and decreasing useful life of vehicles and machinery. Therefore, dust control is of high importance. The most affective and least expensive methods are those involving dust prevention at source. For this purpose various dust control products can be used. The type of dust suppressant to be used usually depends on numerous factors: local climate, type of ground material, road traffic volumes, load to be supported, expected duration of treatment results, etc. Disregarding of type of dust issue and location,…
