Abstract

In Lithuania, since 2007 the suitability of aggregates, used for producing asphalt mixtures, has been tested in accordance with the requirements of TRA MIN 07:2007 The List of Technical Requirements for the Mineral Materials of Roads. When analysing mechanical-physical properties of aggregates the tests of different type of aggregates of different manufacturers were carried out to determine the resistance of aggregates to freezing and thawing (F value), resistance to fragmentation by the Los Angeles Test (LA value) and the Impact Test (SZ value), the polished stone value PSV, resistance to wear MDE and dry particle density ρrd value. Taking into consideration mineral materials, available in Lithuania and used in road building, the suitability tests were carried out and the requirements for their properties were described. When testing mineral materials, used in road building, the suitability of each test method was assessed for Lithuanian climatic conditions. Having made statistical estimations the hypotheses were tested on the correspondence of the same (mechanical-physical) quality indices of different type crushed rock (granite, dolomite and gravel). Having analysed the results of statistical estimations correlation dependencies were determined between the values of mechanical-physical properties F, LA, SZ and ρrd quality indices of aggregates of the same origin. Based on the histograms of frequencies of the impact test values and dry particle density values the hypotheses were tested whether the test data of these quality indices are distributed by normal distribution. It was determined that in Lithuania mechanical-physical properties of crushed gravel, used for producing asphalt mixtures, have not been sufficiently tested, therefore, it is necessary to carry out more comprehensive tests and analysis of crushed gravel of various fractions. The mechanical strength of mixture is simulated and experimentally validated by various techniques developed for sandy soils, namely: strength and deformation properties.
