摘要
集料含泥量对沥青混合料的路用性能有很大影响。含泥量过大影响沥青混合料的高温稳定性和水稳定性,影响集料与沥青的粘结强度。通过试验,研究集料含泥量对集料与沥青粘附性的影响、含泥量对混合料高温稳定性和水稳定性的影响,分析含泥量对混合料路用性能影响的机理,提出控制集料含泥量的技术措施。
The silt content in aggregate has great influences on pavement performance of asphalt mixtures. Excessive silt content affects high -temperature stability and water stability of asphalt mixtures as well as cohesive strength between aggregate and asphalt. This paper via test studies influences of silt content in aggregate on adhesion between aggregate and asphalt and on high - temperature stability and water stability of mixtures, analyzes mechanism of influences on pavement performance of mixtures, and proposes technical measures for controlling silt content in aggregate.
