General information on the use and application of road building materials on the basis of soil and Portland cement
The development of effective materials for the structural layers of pavements based on local strengthened soils by using of different binders and additives is one of the promising areas of road construction research. Strengthened soil-cements are used as the blanket with a wear layer or base of the road pavement. The analysis of domestic and foreign literature in the field of production and application of road building materials based on a soil and Portland cement is shown in the article. Possibilities of production and application of soil-cement, and the influence of technological factors on the quality characteristics of the resulting material are described. It is determined that the rotating of freezing and thawing processes have the most devastating effect on soil-cement layers of road structures. The modification of the soil-cement by various additives can improve the frost resistance and strength properties and will promote to the more active application of its in road construction.
