| Summary: | 碩士 === 逢甲大學 === 土木工程所 === 100 === In recent years, the government will enhance the flatness of the road as the policy focus of the project and related research going on now, mainly to avoid road damage and durability caused by poor security, so the quality level of materials will affect the flatness of the road. In particular, highway construction and laying of the old road improvement, a higher demand on the road of the high-temperature stability of asphalt pavement, low temperature cracking performance. And how to extend the life cycle and performance of the asphalt pavement has become an important subject of the modern road. In Taiwan use the traditional Marshall method, and his general design procedure is the quality of the asphalt material and aggregate property must first determine the project with the compliance requirements, selection of materials (aggregates, asphalt, mineral filler, stabilizer) and select the Grading , and adjustments in the final.
In this study, focusing on the study of the processes of the asphalt concrete, by Marshall test to obtain test data analysis and discussion, find the best synthesis of graded and also cost-effective, also verify that the asphalt plant in Taiwan in accordance with the synthesis Grading with a test basis. Upper and lower limits can be to comply with regulatory requirements, the trial mix to determine the optimum asphalt content in the materials selected, the job.
To assess the nature of asphalt concrete meets the standard specification, Such as all properties are to meet the requirements of the Marshall mix design criteria, is the best mix asphalt content; if some of the nature of non-compliance, you must do some or re-mix design adjustment, With the design is completed, the optimum asphalt content with the economy and can meet all the specification value of the benefits. Appropriate with the design process must be based on the pavement the environment, asphalt clay and aggregate combinations to achieve the quality standards required by the pavement performance.
