【摘要】：為解決鋼橋面疲勞開裂和鋪裝層易損壞這兩大難題，作者所在的研究團(tuán)隊(duì)在理論研究及材料性能研究的基礎(chǔ)上，提出鋼橋面板+STC組合橋面結(jié)構(gòu)。為了保護(hù)STC層不受行車磨損及外界環(huán)境因素的影響，同時(shí)改善表面抗滑性能，有必要研究與之性能相匹配的橋面磨耗層。鑒于TPO作為橋面磨耗層時(shí)性能優(yōu)良，，本研究將TPO應(yīng)用在鋼橋面板+STC組合橋面結(jié)構(gòu)上，組成鋼板+STC+TPO的輕型組合鋼橋面鋪裝體系。本文針對(duì)鋼板+STC+TPO的輕型組合鋼橋面鋪裝體系開展試驗(yàn)研究，考察TPO粘結(jié)性能和耐久性能。主要研究工作如下： （1）在充分分析借鑒國(guó)內(nèi)外薄層聚合物磨耗層的應(yīng)用現(xiàn)狀的基礎(chǔ)上，提出將性能優(yōu)異的TPO用于鋼橋面+STC組合橋面結(jié)構(gòu)。 （2）為解決橋面鋪裝由于層間粘結(jié)力不足引起的結(jié)構(gòu)性損壞，本文對(duì)聚氨酯環(huán)氧樹脂粘結(jié)劑自身的粘結(jié)性能展開研究；采用斜剪、壓剪、拉拔試驗(yàn)測(cè)試TPO-STC結(jié)構(gòu)的層間粘結(jié)性能；通過(guò)組合梁彎拉試驗(yàn)測(cè)試TPO-STC結(jié)構(gòu)層間的相對(duì)位移評(píng)價(jià)結(jié)構(gòu)的層間連續(xù)性。試驗(yàn)結(jié)果表明，聚氨酯環(huán)氧樹脂能夠提供足夠的剪切強(qiáng)度，使上下層間粘結(jié)完好；TPO與STC層間粘結(jié)狀態(tài)良好，常溫和高溫條件下都能保持良好的粘結(jié)強(qiáng)度、剪切強(qiáng)度，且表面進(jìn)行處理后，表面粘結(jié)強(qiáng)度、剪切強(qiáng)度提高；TPO粘結(jié)性能優(yōu)良，TPO-STC的樹脂部分能夠承受荷載作用在TPO-STC界面產(chǎn)生的微小位移，保持TPO-STC結(jié)構(gòu)處于共同受力狀態(tài)。 （3）通過(guò)研究TPO-STC組合結(jié)構(gòu)的高溫穩(wěn)定性能、水穩(wěn)定性能和高溫老化性能對(duì)TPO耐久性能進(jìn)行評(píng)價(jià)。試驗(yàn)結(jié)果顯示，TPO能提供足夠的摩擦值和表面構(gòu)造深度，為車輛安全通行提供有力保障；高溫老化、凍融循環(huán)對(duì)摩擦值、表面構(gòu)造深度的影響較小，試驗(yàn)過(guò)程中未出現(xiàn)車轍現(xiàn)象，同時(shí)界面仍能保持很高的拉拔強(qiáng)度，使TPO-STC結(jié)構(gòu)共同受力。 （4）基于本文試驗(yàn)分析結(jié)果以及相關(guān)工程經(jīng)驗(yàn)，文章提出TPO應(yīng)用于輕型組合鋪裝體系的施工技術(shù)要求，對(duì)施工過(guò)程中樹脂材料的儲(chǔ)存與拌合、STC面板處置、撒布法施工及技術(shù)要求等方面進(jìn)行了詳細(xì)介紹，為實(shí)際工程應(yīng)用提供了施工技術(shù)指導(dǎo)。
[Abstract]:In order to solve the two difficult problems of steel bridge deck fatigue cracking and pavement damage, the author's research team put forward the steel deck STC composite bridge deck structure on the basis of theoretical research and material performance research. In order to protect the STC layer from the influence of driving wear and environmental factors, and to improve the anti-skid performance of the surface, it is necessary to study the wear layer of bridge deck matching its performance. In view of the excellent performance of TPO as the wear layer of bridge deck, this paper applies TPO to the steel deck STC composite deck structure to form the light-weight composite steel deck pavement system of steel plate STC TPO. In this paper, an experimental study on the light-weight composite steel deck pavement system of steel plate STC TPO is carried out, and the bond and durability of TPO are investigated. The main research work is as follows: (1) on the basis of analyzing the application status of thin-layer polymer wear layer at home and abroad, TPO with excellent performance is proposed to be used in steel bridge deck STC composite bridge deck structure. (2) in order to solve the structural damage of bridge deck pavement caused by insufficient bonding force between layers, the adhesive properties of polyurethane epoxy resin binder were studied in this paper. The interlaminar bond behavior of TPO-STC structure was tested by oblique shear, compression shear and pull-out test, and the interlaminar continuity of TPO-STC structure was evaluated by flexural-tensile test of composite beam. The experimental results show that the polyurethane epoxy resin can provide enough shear strength to make the bonding between the upper and lower layers intact. The bonding state between TPO and STC layer is good, and good bond strength and shear strength can be maintained at room temperature and high temperature. After surface treatment, the surface bond strength and shear strength are improved. The bonding property of TPO is excellent. The resin part of TPO-STC can withstand the small displacement caused by load on the interface of TPO-STC and keep the structure of TPO-STC in the state of common force. (3) the high temperature stability, water stability and high temperature aging properties of TPO-STC composite structure were studied to evaluate the durability of TPO. The test results show that TPO can provide enough friction value and surface structure depth to provide a strong guarantee for the safe passage of vehicles. High temperature aging, freezing-thawing cycle has little effect on friction value and surface structure depth. No rut phenomenon appears in the test process. At the same time, the interface can still maintain a high drawing strength, which makes the TPO-STC structure under common stress. (4) based on the test and analysis results of this paper and related engineering experience, this paper puts forward the technical requirements for the application of TPO in light-duty composite pavement system, the storage and mixing of resin materials in the construction process, and the disposal of STC panel. The construction and technical requirements of spreading method are introduced in detail, which provides technical guidance for practical engineering application.
