硬质沥青及其混合料路用性能的试验研究
|
摘要
近年来,我国高速公路路面早期损坏严重。从最早出现的水破坏到现在的车辙,开裂,如何防治沥青路面的早期破坏一直是路面研究者的重点研究内容。国外广泛应用的硬质沥青,柔性基层这些针对沥青路面破坏现象的有效措施渐渐的被国内研究者熟悉并研究采用。在这个背景下,本文研究了硬质沥青应用于中下面层以及柔性基层时的路用性能,这对硬质沥青在国内的发展应用具有重要的学术价值和参考作用。
本文从硬质沥青的性能研究开始,通过大量的室内试验,主要研究了以下内容:
第一,硬质沥青的常规试验以及SHRP PG分级试验。研究表明硬质沥青具有优良的高温性能,低温性能存在不足,但是在本文开展试验的河南省,是可以满足路用要求的。
第二,本文将贝雷法引入配合比设计。选取了AC-20C和AC25C以及ATB30,ATB40这几种工程应用较普遍的混合料进行试验研究。通过马歇尔试件体积指标,确定了他们的最佳油石比。
第三,混合料路用性能测试。主要研究了车辙试验,极限拉伸试验,水稳定性试验,疲劳性能试验。结果表明硬质沥青具有比SBS改性沥青更优秀的路用性能,如高温稳定性,耐疲劳性能等。通过研究表明,硬质沥青是一种适合应用于中下面层以及基层的材料,具有广阔的应用前景。
The phenomenon of a large number of early damage associated with the development of China's highways. From the water damage to the track and cracking, the problems of how to control the early damage of asphalt pavement surface have been the focus of researcher's study. Hard asphalt and flexible base that widely used at abroad are both effective measures of preventing pavement from damage, and it now has been familiar with by domestic researchers. Against this background, this paper research on the pavement performance which applying hard asphalt to the mid and below surface or to the flexible base layer, which is an important development of applications and reference to the role of academic value.
Though a large number of laboratory test, this paper mainly studies the content as follows:
First, the conventional tests of asphalt and SHRP PG grading test. Research shows that hard asphalt has excellent high temperature performance, low-temperature performance deficiencies, but tests carried out in Henan province show it can also meet the road requirements.
Second, according to the characteristic of the mid and below surface, this article select AC-20C , AC25C and ATB30, ATB40 which are commonly used in engineering to do tests. Through the Marshall specimen volume indicators to determine their best than oilstone.
Third, do the mixture performance tests. Mainly concluding track test, the limits of tensile test, water stability test, fatigue test. The results show that the hard asphalt has better pavement performance than SBS modified asphalt and matrix asphalt, such as high temperature stability, fatigue-resistant properties. The study shows that hard asphalt is suitable for the application of mid and below surface, and it has broad application prospects.
