乳化瀝青在道路養(yǎng)護(hù)中的應(yīng)用
來源：http://www.81tyre.com/ 日期：2023-05-08
乳化瀝青是將熱熔的石油瀝青，經(jīng)過機(jī)械作用，以細(xì)小的微粒分散到含有乳化劑、穩(wěn)定劑的水溶液中形成的水包油乳狀液。下面濟(jì)南瀝青料廠家來講講乳化瀝青在道路養(yǎng)護(hù)中的應(yīng)用事項(xiàng)吧。
Emulsified asphalt is a water in oil emulsion formed by dispersing hot melt petroleum asphalt into an aqueous solution containing emulsifiers and stabilizers through mechanical action. Let's talk about the application of emulsified asphalt in road maintenance by Jinan asphalt manufacturers.
（1）稀漿封層
(1) Slurry sealing layer
稀漿封層是一種由硬質(zhì)耐磨性骨料和瀝青混合級(jí)配組成的冷拌施工技術(shù)。乳化瀝青混合料具有較好的粘附性，能在潮濕的路面上進(jìn)行現(xiàn)場(chǎng)施工。通常情況下，級(jí)配相似的稀漿封層具有較高的穩(wěn)定性、較高的模量和較高的抗形變能力，常被用來填充路面車轍裂縫病害，使路面具有高磨損阻力和好的抗變形能力，大大地增加了路面的強(qiáng)度性能和完整性。應(yīng)用乳化瀝青進(jìn)行稀漿封層，可以大大延長(zhǎng)公路壽命。
Slurry sealing layer is a cold mix construction technology composed of hard wear-resistant aggregate and asphalt mixed grading. Emulsified asphalt mixture has good adhesion and can be used for on-site construction on damp roads. In general, slurry seals with similar grading have high stability, high modulus, and high resistance to deformation. They are often used to fill rutting and crack defects on road surfaces, resulting in high wear resistance and good resistance to deformation, greatly increasing the strength and integrity of the road surface. The application of emulsified asphalt for slurry sealing can greatly extend the service life of highways.
（2）石屑罩面
(2) Stone chip cover
石屑罩面是常用的瀝青高含量道路表面處治養(yǎng)護(hù)技術(shù)方法，它是在道路面層上撒布粘結(jié)料層后再均勻攤鋪同粒徑骨料層，具有柔性和耐磨性特征，摻加聚合物后能夠有效增加粘結(jié)力、耐磨性和路面的抗裂性能。改性后能夠進(jìn)行道路封層和橋梁裂縫修補(bǔ)，可以有效減少路面反射性裂縫。由于乳化瀝青具有好的化學(xué)粘附性和防潮濕等路面修補(bǔ)養(yǎng)護(hù)性質(zhì)，石屑罩面處理后的復(fù)合封層道路表面可承受相當(dāng)大的交通負(fù)載量。
Stone chip overlay is a commonly used asphalt high content road surface treatment and maintenance technology method. It spreads a binder layer on the road surface layer and then evenly spreads the same particle size aggregate layer. It has the characteristics of flexibility and wear resistance. Adding polymer can effectively increase the bonding force, wear resistance, and crack resistance of the road surface. After modification, road sealing and bridge crack repair can be carried out, which can effectively reduce reflective cracks on the road surface. Due to the good chemical adhesion and moisture resistance of emulsified asphalt in road repair and maintenance, the composite sealing layer road surface treated with stone chip overlay can withstand a considerable amount of traffic load.
（3）Cape封層
(3) Cape Seal
Cape封層是利用乳化瀝青在耐磨性稀漿封層下鋪設(shè)柔性石屑罩面的路面處治技術(shù)。這種封層為減緩路面組合裂縫提供了技術(shù)保障，具有表面光滑特性。Cape封層融合了石屑罩面中較高的抗滑性和承載性能以及稀漿封層所具有的平整度優(yōu)點(diǎn)，比單獨(dú)使用稀漿封層或石屑罩面技術(shù)的耐磨性要高，路面養(yǎng)護(hù)中應(yīng)用乳化瀝青進(jìn)行Cape封層能夠充分延長(zhǎng)道路的使用壽命。
Cape sealing layer is a pavement treatment technology that utilizes emulsified asphalt to lay a flexible stone chip overlay under a wear-resistant slurry sealing layer. This type of sealing layer provides technical support for alleviating combined cracks on the road surface, and has a smooth surface characteristic. The Cape seal layer combines the high skid resistance and load-bearing performance of the stone chip overlay, as well as the flatness advantages of the slurry seal layer. It has higher wear resistance than using slurry seal layer or stone chip overlay technology alone. The application of emulsified asphalt for Cape seal layer in road maintenance can fully extend the service life of the road.
（4）噴射修補(bǔ)坑洞
(4) Spray repair of potholes
路面養(yǎng)護(hù)中，噴射修補(bǔ)坑洞是針對(duì)路面凹陷坑洞以及破裂病害采用乳化瀝青進(jìn)行填充修補(bǔ)的技術(shù)方式。采用壓縮空氣將路面坑洞吹干清凈，在坑洞內(nèi)表面涂乳化瀝青并填充骨料進(jìn)行充分混合，后在坑洞上面鋪設(shè)干骨料表面封層，完成修補(bǔ)。噴射修補(bǔ)坑洞技術(shù)不需壓實(shí)程序，修補(bǔ)后的坑洞防水性能和強(qiáng)度性能較高。
In road maintenance, spray repair of potholes is a technical method of using emulsified asphalt to fill and repair potholes and cracks in the road surface. Use compressed air to blow dry and clean the road potholes, apply emulsified asphalt on the inner surface of the potholes, fill with aggregates, and mix thoroughly. Then, lay a dry aggregate surface seal layer on the potholes to complete the repair. The spray repair pothole technology does not require a compaction program, and the repaired pothole has high waterproof and strength performance.
（5）微表處
(5) Microsurface processing
乳化瀝青稀漿罩面的高級(jí)形式就是微表處，微表處適用于重要交通公路的預(yù)防性養(yǎng)護(hù)，主要由聚合物改性乳化瀝青、礦物填料、100%軋碎石料、水和必要的添加劑組成，使用施工設(shè)備邊拌和邊攤鋪。在路面養(yǎng)護(hù)中，微表處用于填補(bǔ)已經(jīng)穩(wěn)定的車轍病害應(yīng)用較多。微表處混合料攤鋪后，可在短時(shí)間內(nèi)開放交通。微表處對(duì)集料組成要求非常高，石料必須耐磨、堅(jiān)固、清潔。微表處所用的乳化瀝青是經(jīng)聚合物改性的，通常是采用SBR膠乳，也可采用SBS改性，殘留物具有較高的軟化點(diǎn)。
The advanced form of emulsified asphalt slurry cover is micro surface treatment, which is suitable for preventive maintenance of important transportation highways. It mainly consists of polymer modified emulsified asphalt, mineral filler, 100% crushed stone material, water, and necessary additives. Construction equipment is used for mixing and paving. In road maintenance, micro surface treatment is widely used to fill stable rutting defects. After paving the micro surface mixture, traffic can be opened for a short period of time. Micro surface treatment requires very high aggregate composition, and stones must be wear-resistant, sturdy, and clean. The emulsified asphalt used in the micro surface is modified by polymers, usually using SBR latex or SBS modification, and the residue has a high softening point.
（6）透層和黏層
(6) Prime layer and adhesive layer
在瀝青路面施工中，透層和黏層是不可或缺的工序，在路面的修補(bǔ)中，由于普通瀝青的均勻性和滲透性比較差，往往在施工后，防滲水和粘結(jié)性達(dá)不到理想的要求，從而對(duì)路面修補(bǔ)后的質(zhì)量造成影響。乳化瀝青在該方面則具有很好的性能，應(yīng)用于養(yǎng)護(hù)維修工程路面鋪筑中有著良好的應(yīng)用效果。
In the construction of asphalt pavement, the prime coat and adhesive layer are indispensable processes. In the repair of the pavement, due to the poor uniformity and permeability of ordinary asphalt, the anti permeability and adhesion often do not meet the ideal requirements after construction, which affects the quality of the repaired pavement. Emulsified asphalt has excellent performance in this area and has good application effects in maintenance and repair engineering pavement.
公路橋梁路面在承載運(yùn)行過程中，往往會(huì)出現(xiàn)不同程度的病害，給交通穩(wěn)定運(yùn)行造成大的安全隱患。運(yùn)用乳化瀝青的科學(xué)性能，針對(duì)公路路面進(jìn)行及時(shí)養(yǎng)護(hù)，是現(xiàn)代交通可持續(xù)發(fā)展的重要技術(shù)保障。您有產(chǎn)品需求就來我們網(wǎng)站http://www.81tyre.com咨詢吧！
