Description

高粘沥青改性剂 技术领域  High viscosity asphalt modifier
本发明涉及的是高粘沥青改性剂， 它适用于制备黑色和彩色高粘沥 青， 用来铺筑高等级道路， 特别涉及的是黑色和彩色降噪排'水性路面的铺 筑。 背景技术  The present invention relates to a high-viscosity asphalt modifier which is suitable for the preparation of black and colored high-viscosity asphalt for paving high-grade roads, and more particularly to the laying of black and colored noise-reducing rows of 'water-based pavements. Background technique
降噪排水路面是一种开级配、 大空隙率的路面结构， 它可以降低车辆 在道路行驶时所产生的噪音， 提高车辆刹车时的摩擦系数， 缩短刹车距 离， 而且还可以将降雨时的路面积水渗入到下面的不透水层， 并且将水通 过路肩部位快速排走， 从而減轻了积水对路面结构造成的损害， 这种路面 结构也可降低雨天车辆高速行驶时路面的眩光现象和水膜平滑现象， 提高 行车安全性。 应力吸收层是一种新型路面结构， 它可以有效降低路面改造 过程中， 原路面产生的反射裂缝； 而且具有防渗水功能， 避免路表的水分 下渗到路基层， 造成对路基的破坏。  The noise-reducing drainage pavement is an open-graded, large-cavity pavement structure, which can reduce the noise generated when the vehicle is driving on the road, improve the friction coefficient of the vehicle when braking, shorten the braking distance, and can also The road area water seeps into the impervious layer below, and the water is quickly drained through the shoulder portion, thereby reducing the damage caused by the accumulated water on the pavement structure. This pavement structure can also reduce the glare of the road when the vehicle is driving at high speed in rainy days. Smoothing with water film to improve driving safety. The stress absorbing layer is a new type of pavement structure, which can effectively reduce the reflection cracks generated on the original pavement during the road reconstruction process. It also has a water seepage prevention function to prevent the water surface of the road surface from infiltrating into the road base layer, causing damage to the roadbed.
降噪排水路面在实际应用中有很多优点， 但是由于结构特殊， 路面空 隙率达到 18 ~ 25%左右， 而一般密级配沥青混凝土路面的空隙率仅为 3% ~ 6%, 所以这就对铺路用沥青胶结料的性能提出了更高要求。 主要原因： ①沥青胶结料必须具有较高的粘度， 以增加胶结料与集料的粘结力， 防止 表面集料在车轮荷载作用下飞散。 ②大空隙率路面结构增加了沥青胶结料 与日光和空气接触的机会， 为防止由此产生的老化， 包裹集料的^青薄膜 要有足够的厚度。 ③由于雨水等往混合料体的浸透， 为确保耐水性， 沥青 对集料应有很好的粘附性。 ④在重交通道路上应用时， 混合料应具有较高 的抗塑性变形能力， 要求沥青胶结料具有较高软化点和粘附性。  Noise-reducing drainage pavement has many advantages in practical applications, but due to the special structure, the pavement void ratio is about 18 ~ 25%, while the general dense grade asphalt concrete pavement has a void ratio of only 3% ~ 6%, so this is paving Higher performance is imposed on the performance of asphalt binders. Main reasons: 1 Asphalt cement must have a high viscosity to increase the adhesion of the binder to the aggregate and prevent the surface aggregate from scattering under the wheel load. 2 Large void ratio pavement structure increases the chance of contact of asphalt binder with sunlight and air. To prevent the resulting aging, the green film of the aggregate must have sufficient thickness. 3 Due to the penetration of rainwater into the mixture, the asphalt should have good adhesion to the aggregate in order to ensure water resistance. 4 When applied on heavy traffic roads, the mixture should have high resistance to plastic deformation, requiring asphalt binders to have higher softening points and adhesion.
因此要求铺筑降噪排水性路面用的沥青胶结料应符合如下要求， 其中 聚合物占混合物的重量百分比足够使所形成的沥青胶结料具有如下特征： 针入度 ( 25°C ) 40 - 80 ( l/10mm ) , 最好是 40 ~ 60 ( l/10mm ) ； 软化点 60 ~ 105°C , 最好是 80 ~ 100°C ; 延度（ 15 °C ) , 50 - 150cm, 最好 50 ~ 130cm; 60°C粘度 10000 ~ 200000Pa«s, 最好是 20000 ~ 100000Pa*s; 韧度 ( 25°C ) 大于 20N*m, 最好大于 25N'm; 抗拉强度（25°C ) 大于 15Ν·ηι, 最好大于 20N*mo 发明内容 Therefore, it is required that the asphalt binder for paving noise-reducing drainage pavement should meet the following requirements, wherein the weight percentage of the polymer is sufficient for the formed asphalt binder to have the following characteristics: Penetration (25 ° C) 40 - 80 ( l/10mm ) , preferably 40 ~ 60 ( l/10mm ) ; softening point 60 ~ 105 ° C , preferably 80 ~ 100 ° C ; ductility ( 15 ° C ) , 50 - 150cm , preferably 50 ~ 130cm; 60 ° C viscosity 10000 ~ 200000Pa «s, preferably 20,000 ~ 100000Pa * s; toughness (25 ° C) is greater than 20N * m, preferably greater than 25N 'm; tensile strength (25 ° C) is greater than 15Ν·ηι, preferably greater than 20N*m o Summary of the invention
