Frost susceptibility of improved soils to pavement subgrade
Lorenc, Daniel ; Špaček, Petr (referee) ; Stehlík, Dušan (advisor)
This diploma thesis deals with the issue of the effect of freezing on soils in subgrades of road structures. The theoretical part compares methods of determining the frost susceptibility of soils used in selected countries of the European Union and the Czech Republic. It also explains the principle of frost heave in subgrade layers. The aim of the practical part is to compare the direct and indirect method of determining frost susceptibility in the Czech Republic and the California bearing ration CBR or the immediate bearing ratio IBI.

Durability of the waste building materials for subgrade
Lorenc, Daniel ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The Bacherol thesis is focused on the use of waste building materials to subgrade of the pavement. Examines in detail advantages and disadvantages of this recycled material. Mainly deal with negative properities like water absorption and frost action, and figure out the dependance on the amount of brick parts in waste buildingng material. It practically verifies California bearing ratio, water absorption and rate of frost action of waste building material. A decisive impact on results will have a number of brick parts in recycled material.
