瀝青路面在使用過(guò)程中色澤的變化主要原因
來(lái)源：http://m.81tyre.com/ 日期：2022-07-25
瀝青路面較水泥混凝土剛性路面具有表面平整、耐磨、施工與維修簡(jiǎn)單、行車舒適、低噪音、少揚(yáng)塵等特點(diǎn)，被廣泛用于各等級(jí)公路路面。瀝青路面在使用過(guò)程中色澤的變化主要原因有哪些呢？
Compared with cement concrete rigid pavement, asphalt pavement has the characteristics of flat surface, wear resistance, simple construction and maintenance, comfortable driving, low noise and less dust, and is widely used in all levels of highway pavement. What are the main reasons for the color change of asphalt pavement during use?
自然老化
Natural aging
瀝青路面在長(zhǎng)期使用的過(guò)程，也是瀝青混凝土材料老化的過(guò)程。隨著各項(xiàng)組成材料路用性能逐漸下降，路面自然會(huì)出現(xiàn)顏色變化。
The long-term use of asphalt pavement is also the aging process of asphalt concrete materials. With the gradual decline of the road performance of various constituent materials, the color of the pavement will naturally change.
剛生產(chǎn)出的瀝青混合料，由于瀝青完全裹附于石料表面，通常整體上呈黑色，鋪筑后大粒徑骨料與細(xì)集料粘結(jié)充分，影響光的反射，所以人們?cè)谝曈X(jué)感受上發(fā)烏，沒(méi)有光澤。經(jīng)過(guò)一段時(shí)間后，大粒徑骨料表面的細(xì)集料被車輪摩擦和水沖刷失去，大骨料表面變得光滑，反光效果增強(qiáng)，人們感覺(jué)路面烏黑油亮。再經(jīng)過(guò)一段時(shí)間之后，由于水分、氧氣、紫外線等因素會(huì)發(fā)生瀝青的老化，骨料表面瀝青被摩擦脫落，石料本身顏色顯露，加上大量灰塵聚集在路面，瀝青路面整體上看上去呈灰白色。
As the asphalt mixture just produced is completely wrapped on the stone surface, it is usually black as a whole. After paving, the large-size aggregate is fully bonded with the fine aggregate, which affects the reflection of light. Therefore, people are dark in visual perception and have no luster. After a period of time, the fine aggregate on the surface of large particle size aggregate is lost by wheel friction and water scouring, and the surface of large aggregate becomes smooth, the reflective effect is enhanced, and people feel that the road is dark and shiny. After a period of time, due to moisture, oxygen, ultraviolet and other factors, the asphalt will age, the asphalt on the aggregate surface will be rubbed off, and the color of the stone itself will be exposed. With a large amount of dust gathering on the pavement, the asphalt pavement looks gray white on the whole.
組成材料本身的顏色
The color of the constituent material itself
瀝青混凝土主要是由瀝青、石料、礦粉等材料，按照一定的配比在嚴(yán)格的控制條件下加工而成。瀝青的顏色決定了瀝青路面的顏色，但對(duì)普通瀝青路面使用中的顏色漸變差異不明顯。石料部分通常的比重在90%以上，所以對(duì)各地區(qū)普通瀝青路面在老化后出現(xiàn)的顏色差異，影響較大。
Asphalt concrete is mainly made of asphalt, stone, mineral powder and other materials, which are processed under strict control conditions according to a certain proportion. The color of asphalt determines the color of asphalt pavement, but the color gradient difference in the use of ordinary asphalt pavement is not obvious. The proportion of stone is usually more than 90%, so it has a great impact on the color difference of ordinary asphalt pavement in various regions after aging.
級(jí)配類別和生產(chǎn)工藝的差別
Difference between grading category and production process
瀝青混凝土在生產(chǎn)過(guò)程中由于質(zhì)量控制的原因（拌合時(shí)間過(guò)短或者瀝青投放量不夠）造成的顏色花白和不均勻，屬于產(chǎn)品質(zhì)量不合格，一般不會(huì)用于施工。需要注意的是，個(gè)別生產(chǎn)廠家生產(chǎn)級(jí)配不合理，為減少瀝青投放量而減低細(xì)集料摻加比例，瀝青路面鋪裝后，顏色整體較亮，但空隙率過(guò)大，水穩(wěn)定性下降。
The graying and uneven color of asphalt concrete caused by quality control (too short mixing time or insufficient asphalt dosage) in the production process belongs to the unqualified product quality and is generally not used for construction. It should be noted that the production grading of individual manufacturers is unreasonable, and the proportion of fine aggregate is reduced to reduce the amount of asphalt. After the asphalt pavement is paved, the color is generally bright, but the void ratio is too large, and the water stability is reduced.
濟(jì)南瀝青生產(chǎn)廠家認(rèn)為SMA瀝青路面對(duì)材料品質(zhì)以及生產(chǎn)與施工的工藝要求高，瀝青混合料在生產(chǎn)、運(yùn)輸以及攤鋪過(guò)程中，稍不注意就會(huì)出現(xiàn)質(zhì)量問(wèn)題，所以對(duì)材料質(zhì)量控制較為嚴(yán)格，有利于提高瀝青路面施工質(zhì)量。
Jinan asphalt manufacturers believe that SMA asphalt pavement has high requirements for material quality and production and construction technology, and quality problems will occur if asphalt mixture is not paid attention to in the production, transportation and paving process. Therefore, the material quality control is relatively strict, which is conducive to improving the construction quality of asphalt pavement.
