彩色沥青混凝土路面的设计与施工要点
(一)彩色路面工程
(1) Colored pavement engineering
1、改性彩色沥青路面:采用改性彩色沥青胶结料、矿物燃料、相同色系的石料、特色添加剂等,经设备热拌、摊铺、压实。色彩鲜艳不退,路面经久耐用。
1. Modified colored asphalt pavement: Using modified colored asphalt binder, mineral fuel, stones of the same color series, characteristic additives, etc., it is hot mixed, spread, and compacted by professional equipment. The colors are bright and long-lasting, and the road surface is durable.
2、高弹性彩色沥青广(操)场:采用特别改性的高弹性彩色沥青胶结料、矿物颜料、特种添加剂、特殊的矿料级配,经设备热拌、摊铺、压实。其高弹性来自工程的整体结构而非塑胶工程的表面,是塑胶广(操)场的换代产品。
2. High elasticity colored asphalt field (operation): using specially modified high elasticity colored asphalt binder, mineral pigments, special additives, and special mineral material gradation, it is hot mixed, spread, and compacted by professional equipment. Its high elasticity comes from the overall structure of the engineering rather than the surface of the plastic engineering, making it a replacement product of the plastic field.
3、反光彩色沥青路面:在彩色沥青路面施工中,采用专用设备向表层加入反光材料。铺筑的路面在灯光照射下呈现鲜艳的彩色,不仅为夜行提供方便,更是一道独特的夜间风光。
3. Reflective colored asphalt pavement: In the construction of colored asphalt pavement, specialized equipment is used to add reflective materials to the surface layer. The paved road surface presents bright colors under the illumination of light, not only providing convenience for nighttime travel, but also creating a unique night scenery.
(二)彩色沥青材料
(2) Colored asphalt materials
1、改性彩色沥青胶结料。各种不同标号的胶结料供用户选用,也可按用户要求的标号生产胶结料。由专用设备运输,直接与用户的拌和站对接供料。
1. Modified colored asphalt binder. Various types of adhesive materials with different grades are available for users to choose from, and adhesive materials can also be produced according to user requirements. Transported by specialized equipment, directly connected to the user's mixing station for material supply.
2、矿物颜料,按用户采购的石料情况,经试验确定颜料用量,可按用户要求提供颜料。
2. Mineral pigments can be provided according to the user's requirements based on the amount of stones purchased and determined through testing.
3、热拌彩色沥青混合料:较近距离范围内可由生产基地直接提供热拌料。
3. Hot mix colored asphalt mixture: Within a relatively close range, the production base can directly provide hot mix materials.
(三)沥青设备制造
(3) Asphalt equipment manufacturing
1、各种储量、产量的导热油快热沥青库、灌。
1. Various reserves and yields of thermal oil for fast heating and energy-saving asphalt storage and filling.
2、各种储量、产量的直热式快热沥青库、灌。
2. Direct heating fast heating energy-saving asphalt storage and filling with various reserves and production capacities.
3、彩色沥青设备;沥青改性、沥青乳化设备;冷、热沥青撒布罐。
3. Colored asphalt equipment; Asphalt modification and emulsification equipment; Cold and hot asphalt spreading tanks.
二、彩色沥青混凝土路面主要性能特点
2、 Main performance characteristics of colored asphalt concrete pavement
(1)具有良好的路用性能,在不同的温度和外部环境作用下,其高温稳定性、抗水损坏性及耐久性均非常好,且不出现变形、沥青膜剥落等现象,与基层粘结性良好。
(1) It has good road performance, and under different temperatures and external environmental conditions, its high temperature stability, water damage resistance, and durability are all very good, without deformation, asphalt film peeling, and other phenomena. It has good adhesion with the base layer.
(2)具有色泽鲜艳持久、不褪色、能耐77℃ 的高温和-23℃的低温,维护方便。
(2) It has bright and long-lasting color, does not fade, can withstand high temperatures of 77 ℃ and low temperatures of -23 ℃, and is easy to maintain.
(3)具有较强的吸音功能,汽车轮胎在马路上高速滚动时,不会因空气压缩产生强大的噪音,同时还能吸收来自外界的其他噪音。
(3) It has strong sound absorption function. When car tires roll at high speed on the road, they will not produce strong noise due to air compression, and can also absorb other noise from the outside world.
(4)具有良好弹性和柔性,“脚感”好,适合老年人散步,且冬天还能防滑,再加上色彩主要来自石料自身颜色,也不会对周围环境造成大的危害。
(4) It has good elasticity and flexibility, good foot feel, and is most suitable for elderly people to walk. It can also prevent slipping in winter. In addition, the color mainly comes from the color of the stone itself, and it will not cause significant harm to the surrounding environment.
