碩士 === 國立中興大學 === 土木工程學系所 === 103 === In recent years, due to increased vehicle axle load and tire pressure, so that the contact pressure of the tire and the pavement dramatically, resulting in a lot of the actual occurrence of severe rutting and pavement damage ahead of time, such as stripping, rutting deformation, cracks, holes and other phenomena, Pavement relatively lower quality of service. The main of this study was to investigate the two different surfaces in the super fine aggregate crushing pavement graded to resist deformation of the impact of permanent passes under the restricted zone, in accordance with specification ASTM C1252 (Fine Aggregate Angularity) and bring to strike a fine aggregate crushing two different surfaces, with the same asphalt cement and graded AC-20 (super pavement through below the restricted zone), Marshall mix design method to determine the optimum amount of oil and the production of asphalt concrete test specimen, and then explore the different fine aggregate crushing test through a series of mechanical properties the face of this asphalt concrete mixtures.
