针对沥青路面的车辙损坏,通过掺加改性剂PR/RA以提高沥青混凝土模量,达到有效提高路面抗车辙能力的目的。介绍了高模量沥青混凝土(HMAC)的研究成果,如提出基于抗车辙功能高模量沥青混凝土的合理设置层位和模量值的合理取值范围、抗车辙能力强的高模量沥青路面结构组合,以及高模量沥青混凝土路面典型结构等。并结合试验路实体工程,提出高模量沥青混凝土路面的施工工艺与质量控制技术。
In view of the asphalt pavement rutting damage, this paper adding the modifier PR / RA to increase the modulus of asphalt concrete, the objective of improving pavement anti-rutting ability effectively can be achieved. This paper introduce high modulus asphalt concrete ( HMAC ) research resuits briefly, which based on the function such as the reasonable position, the reasonable range of modulus values of rutting resistance and anti-rut ability of high modulus asphalt pavement structure combination of high modulus asphalt concrete, and the high modulus asphalt concrete pavement typical structure etc.. Combined the test road, high modulus asphalt concrete pavement construction technology and quality control technology can be put forward.
