AK-16A 配合比设计准则研究

AK-16A是广东省沥青混凝土路面抗滑磨耗层的典型结构，抗滑磨耗层的关键技术问题是抗滑和密水，而抗滑与密水是一对矛盾，由于实践经验不足，致使水损害成了广东省高速公路沥青混凝土路面的主要病害之一。为进一步提高广东省抗滑磨耗层配比设计水平，克服水损害，本文着重研究了AK-16A抗滑磨耗层混合料级配曲线位置和形状对混合料马歇尔指标的影响，归纳出抗滑磨耗层配比设计准则。

Research on Design Principles of AK-16A Proportioning

AK-16A is the typical structure for the skid-resistant wearing courses of bitumen pavement in Guangdong Province. For the skid-resistant wearing courses the critical problem is the skid-resistant property and water-tightness, but the skid-resistant property and the water-tightness are contradicted each other. The water damage becomes one of main problems for the expressway pavements due to the lack of practical experiences. In order to improve the level of the proportioning design for the skid-resistant wearing courses and to overcome the problem of water damage, this paper focues the study on the influences of the position and shape of the mixture grading charts for the skid-resistant wearing course AK-16A on the Marshall Index and sums up design principles for the skid-resistant wearing courses.
