沥青砼路面的改色施工工艺
来源：http://www.ycgjglcl.com/ 日期：2022-06-15
新铺筑的沥青路面未经过车辆轮胎的弹性揉搓，沥青混合料中的沥青不能充分的泛油，路面空隙较大。改色剂喷涂施工时会渗透到空隙与游离的沥青产生少许反应。所以用沥青改色保护剂给新旧沥青路改色时需要了解施工注意事项再施工。
The newly paved asphalt pavement has not been elastically rubbed by vehicle tires, and the asphalt in the asphalt mixture cannot be fully flashed, so the pavement gap is large. During spraying, the color modifier will penetrate into the gap and react with the free asphalt. Therefore, it is necessary to understand the construction precautions before using asphalt color changing protective agent to change the color of old and new asphalt roads.
1、新铺筑的济南沥青砼沥青面层尽量是开放交通1周后再进行改色施工。如果工期紧张，必须在新铺筑路面的后2天。
1. The newly paved Jinan asphalt concrete asphalt surface course shall be subject to color change construction after opening the traffic for one week. If the construction period is tight, it must be 2 days after the new pavement is paved.
2、在天气晴好的条件下，用轮胎压路机多次碾压，轮胎反复揉搓新铺筑沥青路面，改善沥青泛油条件，再进行改色施工。
2. Under the condition of fine weather, use the tire roller to roll for many times, and repeatedly rub the tires to newly pave the asphalt pavement, improve the asphalt oil flashing conditions, and then carry out the color modification construction.
3、如喷涂过程中出现路面发黄的情况，需调高喷枪嘴与路面距离或喷涂机压力调整为6MPa，并且喷涂时喷嘴与路面成45度夹角（此方法旨在减轻改色剂对沥青路面颗粒的渗透度，避免改色剂完全包裹碎石颗粒，导致颗粒表面无包裹油膜而脱落）。
3. If the road surface turns yellow during spraying, it is necessary to increase the distance between the spray gun nozzle and the road surface or adjust the pressure of the spraying machine to 6Mpa, and the nozzle forms an included angle of 45 degrees with the road surface during spraying (this method aims to reduce the permeability of the color modifier to the asphalt pavement particles and avoid the color modifier completely wrapping the gravel particles, resulting in the particles falling off without wrapping the oil film on the surface).
沥青砼路面比普通路面多了些优势：
Asphalt concrete pavement has more advantages than ordinary pavement:
1、厚度较薄：厚度非常的薄，因此不会影响隧道等路面的通行净高度，并且重量也比较轻，不会增加桥梁、路面基础的负担。
1. Thin thickness: the thickness is very thin, so it will not affect the net traffic height of roads such as tunnels, and the weight is relatively light, which will not increase the burden of bridges and pavement foundations.
2、防滑性能更好：彩色沥青路面采用的集料是一种人工合成的材料，具有非常高的磨光值，通过粘结剂将集料在既有路面上，可以显着增加路面的干燥和雨天抗滑性能。
2. Better anti-skid performance: the aggregate used for the color asphalt pavement is a kind of synthetic material with very high polishing value. The dry and rain anti-skid performance of the pavement can be significantly increased by applying the aggregate to the existing pavement through the binder.
3、粘结强度高：彩色沥青路面所采用的粘结剂属于有机、无机结合性材料，对于各种材料，沥青砼、水泥砼、钢铁、木材等具有很强的粘结强度，而且适用范围宽。
3. High bonding strength: the binder used for color asphalt pavement belongs to organic and inorganic binding materials. It has strong bonding strength for various materials, such as asphalt concrete, cement concrete, steel, wood, etc., and has a wide range of applications.
4、颜色丰富，多选择：目前彩色沥青路面采用的颜料有：红、黄、棕、橙、绿色等等，可自由选择；而且色彩艳丽持久，改变了原来传统路面的面貌，即使集料被磨损也不会褪色。
4. Rich colors and multiple choices: at present, the pigments used for color asphalt pavement include red, yellow, brown, orange, green, etc., which can be freely selected; Moreover, the color is bright and lasting, changing the appearance of the original traditional pavement. Even if the aggregate is worn, it will not fade.
5、施工方便，固化迅速：济南沥青砼在施工过程中，断交时间比较短，有利于在城市里比较繁忙的路段施工或进行的抢修工程。可在常温环境下使用，较利于环境的保护，不需要大型机械设备，可在狭小区域施工。
5. Convenient construction and rapid solidification: Jinan asphalt concrete has a short time of disconnection during construction, which is conducive to construction in busy sections of the city or rush repair works. It can be used in normal temperature environment, which is more conducive to environmental protection. It does not need large machinery and equipment, and can be constructed in narrow small areas.
