【摘要】：半剛性基層施工技術(shù)在國內(nèi)的研究較多，，在國內(nèi)多省市地區(qū)得到了大面積的推廣應(yīng)用，鋪筑效果良好，材料的路用性能顯著提高，但目前施工技術(shù)應(yīng)用的單層鋪筑厚度卻僅限于16～20cm，基層需要采取分層施工，分層施工受材料層間接觸狀態(tài)的影響，對路面構(gòu)成整體性能差，分層施工周期長，從而施工成本增加。大厚度攤鋪施工存在材料離析控制、壓實(shí)度控制標(biāo)準(zhǔn)以及檢測方法等方面問題需要深入研究解決。大厚度施工技術(shù)的成功應(yīng)用顯著增加了水泥穩(wěn)定碎石基層的整體性能。 本論文以振動(dòng)壓實(shí)法為試驗(yàn)手段，對水泥穩(wěn)定碎石進(jìn)行路用性能研究，提出相應(yīng)的大厚度施工技術(shù)、質(zhì)量控制和驗(yàn)收評價(jià)指標(biāo)，從而推廣和規(guī)范化該項(xiàng)技術(shù)的應(yīng)用。首先對水泥穩(wěn)定級(jí)配碎石進(jìn)行配合比優(yōu)化及路用性能研究；其次對大厚度施工碾壓設(shè)備、碾壓工藝、養(yǎng)生、壓實(shí)度差異控制、防離析處理措施等進(jìn)行研究，確定大厚度水泥穩(wěn)定碎石基層施工技術(shù)；再次對壓實(shí)度檢測方法及現(xiàn)場質(zhì)量控制方法進(jìn)行研究，確定大厚度水泥穩(wěn)定級(jí)配碎石基層質(zhì)量控制與驗(yàn)收評價(jià)方法；最后進(jìn)行實(shí)體工程應(yīng)用以及技術(shù)經(jīng)濟(jì)的分析。 通過本文的研究能有效的提高水泥穩(wěn)定碎石基層施工效率，減少早期開裂破壞，進(jìn)一步改善和提高公路瀝青路面的使用質(zhì)量，延長使用壽命，適應(yīng)全國日益增長的經(jīng)濟(jì)建設(shè)和行車安全舒適的需求，實(shí)現(xiàn)更大的經(jīng)濟(jì)和社會(huì)效益。
[Abstract]:The semi-rigid base construction technology has been widely studied in China. It has been widely used in many provinces and cities in China. The paving effect is good, and the pavement performance of the material is improved significantly. However, at present, the thickness of single layer paving is limited to 16 ~ 20 cm. The layered construction is required. The layered construction is affected by the contact state between the layers of materials, and the overall performance of the pavement is poor, and the construction period of the layered construction is long. As a result, construction costs increase. The problems of material segregation control, compactness control standard and testing method need to be deeply studied and solved in the construction of large thickness paving. The successful application of large thickness construction technology has significantly increased the overall performance of cement stabilized crushed stone base. In this paper, the vibratory compaction method is used to study the road performance of cement stabilized macadam, and the corresponding large thickness construction technology, quality control and acceptance evaluation index are put forward, so as to extend and standardize the application of this technology. First of all, the mixture ratio optimization and road performance of cement stabilized graded crushed stone are studied; secondly, the compaction equipment, compaction process, health maintenance, compaction degree difference control, anti-segregation treatment measures and so on are studied in the construction of large thickness compacting equipment, compaction process, health maintenance, compaction degree difference control, anti-segregation treatment and so on. The construction technology of cement stabilized macadam base course with large thickness is determined, the compaction testing method and field quality control method are studied again, and the quality control and acceptance evaluation method of cement stabilized crushed stone base course with large thickness cement grade are determined. Finally, the application of entity engineering and the analysis of technical economy are carried out. Through the research of this paper, it can effectively improve the construction efficiency of cement stabilized crushed stone base, reduce the early cracking and damage, further improve and improve the use quality of highway asphalt pavement, and prolong the service life. To meet the increasing economic construction and the demand of driving safety and comfort, to achieve greater economic and social benefits.
