Title of the articleRefinement of local staked priming coats by grain size distribution regulation
Abstract.This work is devoted to solving the actual problem of the Republic of Tatarstan on the connection of rural settlements by roads with a firm covering and expansion of the range of road-building materials from local ground. On the basis of the literary review the basic lacks of the local ground strengthened by cement are defined. Authors offer a method of refinement of the local strengthened clay ground by regulation of the grain structure. The work purpose was to study the physical and mechanical properties of the local ground of various grain structure strengthened by cement. According to the research the influence of the maintenance of sand particles on physical and mechanical properties of the local strengthened clay ground is determined. Test results showed that increasing the maintenance of the sand fraction of the material promotes a durability gain on compression and stretching at bend and to sharp increase in frost. Thus it was established that refinement of the local strengthened ground for efficient road clothes of rural highways, is possible by introduction in the ground, in addition to knitting, grain additives. Regulating grain structure, i.e. quantity of sand and clay particles, it is posible to change physical and mechanical properties of the strengthened ground depending on area of their application. Based on the analysis of the received data, the scope of the investigated local strengthened ground of various grain structure is defined.
Keywords.Staked priming coats, grain-growing structure, durability and frost resistance of staked priming coats.
