【摘要】：隨著我國(guó)經(jīng)濟(jì)的發(fā)展、公路交通量的日益增大，已建成的水泥混凝土路面經(jīng)過(guò)一段時(shí)間運(yùn)營(yíng)以后，逐漸出現(xiàn)結(jié)構(gòu)性和功能性的破壞，嚴(yán)重降低了道路的路用性能，縮短了道路的使用壽命。交通運(yùn)輸?shù)牟粩喟l(fā)展，對(duì)道路服務(wù)水平提出了更高的要求，對(duì)已經(jīng)建成進(jìn)行服役的水泥混凝土路面改造和修復(fù)，已成為道路科研工作者所面臨的一個(gè)重要現(xiàn)實(shí)問(wèn)題。本文以黑龍江省沾北公路起點(diǎn)于沾五公路與龍鎮(zhèn)至北安公路（X216）交叉處，終點(diǎn)前嫩公路K343+200段水泥混凝土路面大修改造實(shí)際工程為研究對(duì)象，在調(diào)查舊水泥混凝土路面使用狀況的基礎(chǔ)上，對(duì)原有舊水泥混凝土路面加鋪改造設(shè)計(jì)與施工方案展開重點(diǎn)研究，具體包括以下幾個(gè)方面： 1.通過(guò)對(duì)沾北公路起點(diǎn)于沾五公路與龍鎮(zhèn)至北安公路（X216）交叉處，終點(diǎn)前嫩公路K343+200段進(jìn)行該公路的路面結(jié)構(gòu)、路面破損狀況以及路面彎沉的調(diào)查，全面評(píng)價(jià)了舊水泥混凝土的路面狀況，并分析水泥混凝土路面不同病害產(chǎn)生的原因，，為舊水泥混凝土路面處治方法及加鋪層方案設(shè)計(jì)提供依據(jù)。 2.依據(jù)對(duì)舊水泥混凝土路面實(shí)際狀況調(diào)查結(jié)果，及對(duì)舊水泥混凝土路面處理技術(shù)及加鋪方法進(jìn)行比較分析，確定對(duì)舊水泥混凝土路面采用打裂壓穩(wěn)技術(shù)進(jìn)行路面處理，并采用分離式瀝青加鋪層進(jìn)行改造；確定了合理的瀝青加鋪層結(jié)構(gòu)設(shè)計(jì)及材料設(shè)計(jì)方案。 3.通過(guò)沾北公路起點(diǎn)于沾五公路與龍鎮(zhèn)至北安公路（X216）交叉處，終點(diǎn)前嫩公路K343+200段水泥混凝土路面改造實(shí)際施工，研究了舊水泥混凝土路面打裂壓穩(wěn)技術(shù)及瀝青加鋪層的施工工藝，對(duì)瀝青混合料的關(guān)鍵環(huán)節(jié)的質(zhì)量控制標(biāo)準(zhǔn)過(guò)程進(jìn)行研究，最終形成了混凝土加鋪瀝青層的技術(shù)，為今后舊水泥路面加鋪瀝青面層的設(shè)計(jì)、決策提供經(jīng)驗(yàn)與借鑒[1]。
[Abstract]:With the development of our country's economy and the increasing traffic volume of highway, the cement concrete pavement that has been built has gradually appeared structural and functional damage after a period of operation, which has seriously reduced the road performance. The service life of the road is shortened. With the continuous development of traffic and transportation, higher requirements have been put forward to the road service level, and it has become an important practical problem for road researchers to rebuild and repair the cement concrete pavement that has already been built and served. In this paper, the starting point of Zhanbei Highway in Heilongjiang Province is at the intersection of Zhanwu Highway and Longzhen to Bei'an Highway X216), and the actual project of overhaul and renovation of cement concrete pavement in K343,200 section of Highway K343,200 before the end of the highway is taken as the research object. Based on the investigation of the usage of the old cement concrete pavement, the design and construction plan of the old cement concrete pavement overlay is studied, including the following aspects: 1. Through the investigation of the pavement structure, the condition of pavement damage and the pavement deflection at the crossing of Zhanbei Highway and Longzhen to Bei'an Highway, and K343,200 section of Qianen Highway before the end of the highway, This paper comprehensively evaluates the pavement condition of old cement concrete, and analyzes the causes of different diseases of cement concrete pavement, which provides the basis for the treatment method of old cement concrete pavement and the design of overlay scheme. 2. According to the investigation results of the actual situation of the old cement concrete pavement and the comparison and analysis of the treatment technology and the overlay method of the old cement concrete pavement, it is determined that the old cement concrete pavement is treated by crack and pressure stabilization technology. The structure design and material design scheme of asphalt overlay are determined. The actual construction of cement concrete pavement reconstruction of K343,200 section of Pre-Nen Highway is carried out through the crossing of Zhanbei Highway and Longzhen to Bei'an Highway X216). This paper studies the crack stabilization technology of old cement concrete pavement and the construction technology of asphalt overlay, studies the quality control standard process of the key link of asphalt mixture, and finally forms the technology of concrete overlay asphalt layer. This paper provides experience and reference for the design and decision making of asphalt pavement overlay with old cement pavement in the future [1].
