【摘要】：隨著經(jīng)濟的突飛猛進，我國的公路事業(yè)也迅速發(fā)展起來，尤其是高速公路的發(fā)展取得了令人矚目的成績。瀝青路面作為高速公路的主要路面形式，還存在很多路面病害，如車轍、裂縫和水損壞等等。因此，道路瀝青作為瀝青路面的重要的道路建筑材料，其性能的優(yōu)良直接關(guān)系到整個瀝青路面的質(zhì)量，所以對其性能的研究是非常重要的。本文主要對道路瀝青的性能進行了綜合分析和評價。 本文主要通過對五種基質(zhì)瀝青和五種SBS改性瀝青的高溫性能、低溫性能、感溫性能和老化性能四個方面做了瀝青性能指標的分析。瀝青為多指標材料，先從每個性能的優(yōu)劣出發(fā)對基質(zhì)瀝青和SBS改性瀝青進行了優(yōu)劣排名，，然后總結(jié)瀝青的這四種性能，提出一個粗略地綜合評價瀝青性能的評分標準，主要對多種瀝青的室內(nèi)試驗，通過得到的實驗數(shù)據(jù)分析了瀝青的路用性能，得到了評價瀝青優(yōu)劣的方法。首先是對相同標號（70#）的5種基質(zhì)瀝青和5種SBS改性瀝青進行了高溫性能、低溫性能、感溫性能和老化性能的分析與評價，分析了瀝青的老化規(guī)律，包括瀝青老化后三大指標的變化規(guī)律和瀝青老化后組分的變化規(guī)律，并分析了瀝青的組分與瀝青路用性能之間的關(guān)系;其次是把瀝青的評價指標綜合起來分析瀝青性能的優(yōu)劣，提出一種評價瀝青綜合性能的簡易評分標準，以此來判別瀝青的優(yōu)劣;最后通過對瀝青混合料路用性能的驗證，得出這種評分方法在評價道路瀝青性能方面的可行性，為我國的瀝青性能評價提供一種可行的參考方法。
[Abstract]:With the rapid development of economy, China's highway industry has also developed rapidly, especially the highway development has made remarkable achievements. Asphalt pavement, as the main pavement form of expressway, still has many pavement diseases, such as rutting, crack and water damage and so on. Therefore, as an important road building material of asphalt pavement, the performance of asphalt is directly related to the quality of the whole asphalt pavement, so it is very important to study its performance. In this paper, the performance of road asphalt is comprehensively analyzed and evaluated. In this paper, five kinds of asphalt matrix and five kinds of SBS modified asphalt are analyzed in four aspects: high temperature performance, low temperature performance, temperature sensing property and aging property. Asphalt is a multi-index material. This paper first ranks the base asphalt and the SBS modified asphalt according to each performance, then summarizes the four properties of asphalt, and puts forward a standard for evaluating the asphalt performance in a rough and comprehensive way. The road performance of asphalt is analyzed based on the experimental data, and the method of evaluating asphalt is obtained. Firstly, five kinds of base asphalt and five kinds of SBS modified asphalt with the same grade (70#) were analyzed and evaluated for their high temperature, low temperature, temperature sensing and aging properties, and the aging rules of asphalt were analyzed. It includes the change law of three major indexes after asphalt aging and the change law of asphalt component after aging, and analyzes the relationship between asphalt component and asphalt road performance, secondly, synthesizes the evaluation index of asphalt to analyze the quality of asphalt performance. This paper puts forward a simple scoring standard to evaluate the comprehensive performance of asphalt, which is used to judge the quality of asphalt. Finally, the feasibility of this scoring method in evaluating the performance of road asphalt is obtained by verifying the pavement performance of asphalt mixture. It provides a feasible reference method for asphalt performance evaluation in China.
