Description

一种水泥混凝土路面养护剂及制备方法 A cement concrete pavement curing agent and preparation method

技术领域 FIELD

[0001] 本发明涉及一种可改善水泥混凝土路面表层性能,密封路面,提高道路抗滑能力,美化路面的水泥混凝土路面养护剂及制备方法,属于浙青路面维护和修理相关领域。 [0001] The present invention relates to an improvement in the surface properties of the cement concrete pavement, road sealing, improve road skid resistance, preparation of curing agents and cement concrete pavement road landscaping, green road belonging Zhejiang maintenance and repair related art.

背景技术 Background technique

[0002] 水泥混凝土路面具有承载能力大、稳定性好、使用寿命长、日常养护费用少等优点,现广泛应用于飞机场跑道、高速公路、干线公路、城市道路、厂矿道路以及停车站场、隧道内路面和过水路面。 [0002] cement concrete pavement with a large carrying capacity, good stability, long life, low routine maintenance costs, etc., are widely used in airport runways, highways, trunk roads, urban roads, factories and roads and parking stations, tunnel and road pavement over the water. 然后其维修时间长、成本高、行车舒适性差、噪音大和易扬尘等缺点,越来越不能适应于现代道路发展需要。 Then its long service time, high costs, poor driving comfort, noise is large and easy to dust and other shortcomings, increasingly unable to meet the development needs of the modern road. 特别是过去几年水泥路面被频繁应用于在高速公路的桥面、隧道路面在通行多年后,路面摩擦会衰减或出现断板、错台和接缝破坏等病害,对道路的安全性、畅通性带来极大影响。 Especially in the past few years is frequently used in cement pavement in highway bridge, tunnel road after the passage of many years, the road surface friction or attenuation occurs off the board, dislocation and destruction of joints and other diseases, safety on the road, smooth of tremendous influence. [0003] 为了增加道路美观、行车舒适性和便于维修管理,近几年出现“白改黑”、微表处等工艺,这些工艺都是在白色路面上加铺一层浙青混凝土面层。 [0003] In order to increase road appearance, driving comfort and ease of maintenance management, in recent years, technology "white to black", micro-surfacing and the like appear, these processes are on a white Pavement concrete surface layer of Zhejiang green. 在实际使用过程中,由于原路面自身缺陷和加铺工艺的不成熟,应用效果仍不理想。 In actual use, since the original pavement and Paving own shortcomings immature technology, the application is not satisfactory. 随着水泥路面养护技术的发展,最近也出现了超级微表处技术,它是在水泥路面铺罩一层环氧金刚砂或一层阻燃浙青,进行抗滑处理,有效地提高路面的附着系数的一种技术,然而该技术仍处于探索中,没能推广应用。 With the development of cement pavement maintenance technology, recently there have been super-micro-surfacing technology, which is laid in the cover layer of epoxy cement road or diamond layer of flame retardant Zhejiang Green, Sliding treatment effectively improve road adhesion a technology factor, but the technology is still in the exploration, failed to promote the application.

[0004] 在我国高速公路路面、城市道路路面上,白色路面仍占较大比例,特别是钢桥面、隧道路面等。 [0004] on the highway pavement, road pavement of the city, still accounts for a large proportion of the white pavement, especially steel bridges, tunnels and other roads. 根据道路建设的周期,这些路面正面临着维修养护。 According to the cycle road construction, which is facing the road repair and maintenance. 例如,在隧道内路面上,水泥混凝土路面经过一段时间的运营后,路面的防滑性能会逐渐衰减,这给行车安全带来极大隐患,采用加铺热浙青、微表处、罩面等传统的处理方式会加高路面,缩小隧道的净高,进而影响大型车辆的通行。 For example, on the tunnel road, concrete pavement after a period of operation, the performance of non-slip road will gradually decay, which brings great risks to road safety, the use of overlay heat Zhejiang Green, micro-surfacing, overlay, etc. the traditional approach would be raised pavement, narrow tunnel clear height, thereby affecting the passage of large vehicles. 在净高和承重两大因素的限制下,在桥面、隧道路面上加铺热浙青、微表处、罩面等传统处理方式显然不能适应道路本身要求。 In two factors limit the clear height and bearing, on the deck, hot tunnel Pavement Zhejiang Green, micro-surfacing, overlay and other traditional approach is clearly not meet the requirements of the road itself. 那么,选择新材料、新工艺对原水泥路面进行处理,以期达到既起到不抬高路面,又能提高路面的抗滑性能,改善路面性能及美化路面的目的显得尤为重要。 Then, select the new materials, new techniques for processing the original concrete pavement in order to achieve both play not raise the road, but also improve the skid resistance of the road surface, improving pavement performance and beautify the road is very important.
