Сriteria for research of the process of dispersion of the system of hydrate lime-water

The process of dispersion of slaked lime in a vibrating activator of the bunker type is investigated. The nature of the change in the viscosity of lime dough during machining by vibration and rotary viscometer has been studied. It is established that the process of vibroactivation of hydrated lime successively goes through the stages of proportional growth of dynamic viscosity, slowing down its growth and cessation of dispersion. The efficiency of using the vibration method for determining the viscosity of the hydrated lime – water system is shown.

Rheology, Deformational Properties and Fatigue of the Asphalt Mixtures

The deformational properties and fatigue of asphalt layers are important for the design and assessment of semi-rigid and flexible pavements. The Two-point Bending Test was used for determination of deformational characteristics of asphalt mixtures on Department of Construction Management in Zilina. The results are evaluated with the KATEMS assessment software. The long-term research lead to estimation of deformational characteristics and fatigue of different types of asphalt mixtures. The tests have shown a positive impact of additives (ground rubber, hydrate lime component) on the results of these mixtures. This article is focused on assessment of deformational properties and fatigue of selected types of asphalt mixtures.
