Multi-scale study of the polishing behaviour of quartz and feldspar on road surfacing aggregate

In this paper, the exact mechanisms as to how petrographic properties of aggregate influence the polishing behaviour quantitatively were identified. Since the aggregate is composed of the different rock-forming minerals, the analyses conducted in this research project focused not only on the aggregate but also on crystals/minerals. The hardest and most abundant rock-forming minerals found on earth – quartz and feldspar – were investigated with polishing tests with the Aachen Polishing Machine on granite aggregates from four sources which exhibit different mineralogical properties. Changes of the aggregate texture and minerals were studied based on texture measurements and skid resistance measurements obtained by means of the Pendulum Test and the Wehner/Schulze device. The influences of mineral composition and crystal size on the changes of the micro-texture and skid resistance of the aggregates were determined by comparing the four granites. The polishing and wearing behaviour of quartz and various feldspars (albite, microcline and plagioclase) were characterised quantitatively by means of a spectral analysis and abrasion analysis. The results show that the micro-texture of exposed minerals is greatly smoothened on wavelengths from 100 to 500 μm. Fine-grained quartz or feldspar crystals tend to be rougher than medium of large-sized crystals. Quartz exhibits more favourable properties than feldspar between 100 and 500 μm; this is especially true for fine quartz crystals. The correlation that more content of coarse-grained quartz leads to high friction value cannot be proved in this research.

故县水库导流洞的磨损情况分析及防磨损措施

入县水库导流洞实测磨损资料，对导流洞磨损的特点、原因及速度进行了分析。结果表明：以施工弃渣为主的推移质过洞是造成导流表面磨损的主要原因。此外，悬移质、水流流态及材料的抗磨性能对导流洞的磨损也是一定影响，并在此基础上提出了导流洞的防磨损措施。     

不同SBS含量的改性沥青对薄层磨耗层混合料路用性能影响

分析了不同SBS掺量(4.0%,4.5%,5.0%,5.5%)改性沥青对密实断级配薄层磨耗层混合料浙漏特性、飞散特性、高温稳定性及水稳定性等路用性能的影响.试验表明,随着SBS含量的增加,改性沥青的技术指标有明显提高,混合料的各项性能随之提高,当SBS含量大于5.0%时,改善效果最为显著,但是由于SBS含量增加,改性沥青存储稳定性有所下降。对剪切加工水平的依赖性增强,考虑到薄层磨耗层混合料的高技术要求,推荐SBS的掺量最好在5.0%以上,考虑原料造价和剪切加工水平,SBS的加入量最好控制在5.0%～6.0%。
