Rapid repairing method for concrete pavement
The invention relates to the technical field of road materials, in particular to a rapid repairing method for a concrete pavement. The method comprises the following steps: pouring an early-strength concrete pavement repairing material doped with self-repairing microspheres on a pavement to be repaired, and maintaining. The preparation method of the self-repairing microspheres comprises the following steps: adding sodium alginate, styrene-maleic anhydride and nano CaCO3 into deionized water, and after the sodium alginate is completely dissolved, adjusting the solution to be alkaline and stable to obtain a mixed solution; dropwise adding a liquid polyethylene glycol-bisphenol A-epichlorohydrin copolymer into the mixed solution, uniformly mixing, standing, curing, washing and drying.
本发明涉及道路材料技术领域，具体而言，涉及一种混凝土路面快速修补方法。该方法将掺有自修复微球的早强型混凝土路面修补材料浇筑于待修补路面，并进行养护。该自修复微球的制备方法包括将海藻酸钠、苯乙烯‑马米酸酐、纳米CaCO3加入到去离子水中，待海藻酸钠完全溶解后，调节溶液至碱性至稳定得到混合液；将液态聚乙二醇‑双酚A‑环氧氯丙烷共聚物滴加到所述混合液中混匀，静置固化后洗涤干燥。
