COMPACTABILITY OF BITUMINOUS MIXTURES - DEFINITION, DETERMINING INFLUENCING FACTORS, QUANTIFYING THE INFLUENCE
| 项目名称： | COMPACTABILITY OF BITUMINOUS MIXTURES - DEFINITION, DETERMINING INFLUENCING FACTORS, QUANTIFYING THE INFLUENCE |
| 摘要： | THE OBJECT OF THE RESEARCH IS TO STUDY VARIOUS ASPHALT MIXTURES WITH RESPECT TO THEIR COMPACTABILITY IN RELATION TO THE INDIVIDUAL COMPONENTS OF THE MIXTURE. THE VARIOUS MIXTURES ARE TO BE COMPACTED WITH A GRADED AMOUNT OF EFFORT WITH MARSHALL COMPACTION EQUIPMENT. IT IS THEN POSSIBLE TO REPRESENT THE BULK DENSITY OF A MIXTURE IN RELATION TO THE COMPACTIVE EFFORT BY MEANS OF AN EXPONENTIAL FUNCTION. BY MEANS OF REGRESSION CALCULATION THE FACTORS WHICH DESCRIBE THE COMPACTION PROCESS CAN BE DETERMINED NUMERICALLY FOR ANY ASPHALTIC MIXTURE. IN THIS RESEARCH MARSHALL SAMPLES ARE TO BE SUBJECTED TO SYSTEMATIC VARIATION OF THE COMPONENTS FILLER, SAND, PARTICLES LESS THAN 2 MM, TYPE OF BINDER AND NUMBER OF IMPACTS DURING COMPACTION, AND TESTED FOR BULK DENSITY IN ORDER TO DETERMINE THE FACTOR WHICH CONTROLS COMPACTABILITY. THE EXPONENTIAL SOLUTION WILL BE APPLIED TO THE DATA OBTAINED. THROUGH WIDE VARIATION OF THE MIXTURE COMPONENTS IT IS INTENDED TO ESTABLISH THE COMPACTABILITY FACTOR FULLY SO THAT ASPHALTIC MIXTURES CAN BE CHARACTERIZED BY THEIR ABILITY TO BE COMPACTED. |
