实现彩色沥青混凝土强度和抗变形承载能力的高标准
用以彩色透水沥青路面:增强沥青与石料之间的粘结力,确保排水沥青混合料大孔隙结构强度承载能力,抗车辙性能比普通彩色沥青提高4-8倍,抗飞散掉粒性能提高2-4倍。
Color pervious asphalt pavement: enhance the bond between asphalt and stone, ensure the strength and bearing capacity of the large pore structure of the drainage asphalt mixture, improve the rutting resistance by 4-8 times compared with the ordinary color asphalt, and improve the flying particle resistance by 2-4 times.
用以机动车道、公交车道:实现彩色沥青混凝土强度和抗变形承载能力的高标准,结合沥青混合料专项设计,满足重载交通彩色沥青路面复杂的受力环境和苛刻工况。比普通彩色沥青抗车辙强度4-8倍。提高抗低温和疲劳开裂性能50%左右。
For motorway and bus lane: to achieve high standards of strength and deformation resistance of color asphalt concrete, combined with the special design of asphalt mixture, to meet the complex stress environment and harsh conditions of heavy traffic color asphalt pavement. It is 4-8 times stronger than ordinary color asphalt. The low temperature and fatigue cracking resistance are improved by about 50%.
RVA采用沥青拌合楼外加剂工艺,使用普通彩色沥青即可,工艺简单,且适用于绝大多数彩色沥青(脱色沥青)产品的性能增强。同时,改性剂中的抗氧化剂可提高耐老化性能,长期保持彩色沥青路面的鲜亮色彩。
RVA adopts the additive process of asphalt mixing plant, which is simple and suitable for the performance enhancement of most color asphalt products. At the same time, the antioxidant in the modifier can improve the aging resistance and keep the bright color of the colored asphalt pavement for a long time.
