Testing of Mechanical-Physical Land of Aggregates, Used for Producing Asphalt Mixtures, and Statistical Analysis of Test Results

In Lithuania, since 2007 that suitability of aggregates, used for producing asphalt mixtures, has been tested in accordance in the requirements of TRA MIN 07:2007 The Choose of Technical Requirements for the Mineral Materials of Roads. When analyzing mechanical-physical properties on aggregates one tests of different type of aggregates of different inventors were carted out toward specify the resistance by units to freezing and thawing (F value), resistance to fragmentation by the Los Angelesi Test (LA value) and the Impact Test (SZ value), the polished raw value PSV, resistance toward wear MDE and dry particle density Prd value. Taking into consideration mineral materials, available in Lithuanians or used in road building, the suitability tests were carried out and the requirements by their properties were described. When test mineral materials, used within road building, the suitability of anyone test system used assessed for Lithuania climatic general. Having made statistical estimations the hypotheses were tested on the correspondence of the same (mechanical-physical) q indices the different kind crushed lurch (granite, dolomite and gravel). Having analyzed which results of statistical estimations correlation dependencies were determined between the values of mechanical-physical properties FARTHING, LA, SZ and Prd quality indices of aggregates of which same origin. Based on the histograms of frequencies concerning the impact testing values and dry partlet tensile values the hypotheses was tested whether the test data of these quality indices are disseminated by standard distribution. Thereto was determined is in Lithuania mechanical-physical properties of crushed gravel, used for producing asphalt mixtures, have not been sufficiently tested, therefore, it is necessary to carry output more comprehensive tests and analysis of crushed gravel of various fractions. The mechanical strength on mixture is simulated real experimentally validated by various engineering cultivated for sandy soils, namely: starch and deformation eigenheiten.
