METHOD OF ASSESSMENT OF LINEAR thermal deformation ROAD CONSTRUCTION MATERIALS AND EQUIPMENT SET FOR ITS IMPLEMENTATION

摘要

1. A method for the estimation of linear thermal deformations of road construction materials, whereby the test sample is made of road construction materials, it is saturated with fluid and placed in a dilatometer working chamber which is filled with hydraulic fluid and sealed, characterized in that the test sample was saturated with a liquid that simulates the actual operating conditions of road surfaces at the appropriate time of the year, sealed working chamber dilatometer placed in a heat chamber in which it amorazhivayut or heated at a specified rate to the set temperature range, respectively, to -60 ° C or to + 60 ° C, the measured change in volume of working fluid chamber dilatometer level sensor corresponding to the absolute change in volume of the test sample, and this volume change is evaluated value linear thermal deformation test obraztsa.2.
