【摘要】：中國高速公路已經(jīng)逐步從大規(guī)模修建轉(zhuǎn)向全面養(yǎng)護(hù)階段,道路養(yǎng)護(hù)成為潛在而又艱巨的任務(wù)。本文結(jié)合海南省高溫多雨地區(qū)雨后或臺風(fēng)過后反復(fù)爆發(fā)大范圍、小面積坑槽的特征研究一款基于早強(qiáng)型水泥乳化瀝青混凝土及其新型修補(bǔ)工藝的養(yǎng)護(hù)設(shè)備,能夠進(jìn)行快速修復(fù)的小型坑槽養(yǎng)護(hù)設(shè)備,從而實(shí)現(xiàn)瀝青路面快速修復(fù)。以海南高溫多雨地區(qū)的高速路面為對象,針對路面坑槽的成因、修補(bǔ)方法,提出以早強(qiáng)型水泥乳化瀝青混凝土為坑槽修補(bǔ)材料和基于新型材料的“三層修復(fù)法”以及利用路面探測雷達(dá)確定坑槽病害修補(bǔ)范圍和深度的新型修補(bǔ)工藝,依據(jù)新型材料及其新型工藝提出養(yǎng)護(hù)設(shè)備的功能要求,對養(yǎng)護(hù)設(shè)備進(jìn)行了結(jié)構(gòu)設(shè)計(jì),使其具備切割、破碎、攪拌、壓實(shí)與一體的多功能養(yǎng)護(hù)設(shè)備。在此結(jié)構(gòu)設(shè)計(jì)的基礎(chǔ)上,分別進(jìn)行了空載、滿載狀態(tài)下的軸載荷分配、操作穩(wěn)定性操作穩(wěn)定性等校核分析,結(jié)果表明各項(xiàng)性能指標(biāo)均達(dá)到了設(shè)計(jì)要求。設(shè)計(jì)了集成各裝置的第二副車架,利用ANSYS Workbench軟件對第二副車架進(jìn)行滿載和空載起吊狀態(tài)下的結(jié)構(gòu)有限元分析,結(jié)果表明第二副車架強(qiáng)度及其剛度在滿載、空載起吊狀態(tài)下都處于安全范圍內(nèi)。在海南環(huán)島高速公路東線瀝青路面段,采用自制的養(yǎng)護(hù)設(shè)備進(jìn)行了試驗(yàn),試驗(yàn)結(jié)果表明自制的養(yǎng)護(hù)設(shè)備達(dá)到了設(shè)計(jì)要求,基于采用早強(qiáng)型水泥乳化瀝青混凝土和新型工藝以及配套的快速養(yǎng)護(hù)設(shè)備為解決海南高溫多雨地區(qū)路面快速修補(bǔ)提供了一有效方法。
[Abstract]:Highway maintenance in China has gradually changed from large-scale construction to comprehensive maintenance, and road maintenance has become a potential and arduous task. Based on the characteristics of large area and small area potholes in high temperature and heavy rain area in Hainan Province, this paper studies a maintenance equipment based on early strength cement emulsified asphalt concrete and its new repair technology. Small pit maintenance equipment that can be repaired quickly, so that asphalt pavement can be repaired quickly. Taking the high speed pavement in Hainan high temperature and heavy rain area as the object, aiming at the cause of formation of the pavement pothole, the repair method, This paper puts forward a "three-layer repairing method" which takes early strength cement emulsified asphalt concrete as pothole repair material and based on new material, and a new repair technology which uses pavement detection radar to determine the repair range and depth of pothole diseases. According to the functional requirements of the new material and its new technology, the maintenance equipment is designed to have the multi-function maintenance equipment with cutting, crushing, stirring, compaction and integration. On the basis of the structure design, the shaft load distribution and operation stability under the condition of no-load and full load are checked and analyzed respectively. The results show that all the performance indexes are up to the design requirements. The second subframe integrated with each unit is designed, and the structure of the second subframe under full load and no load lifting is analyzed by using ANSYS Workbench software. The results show that the strength and stiffness of the second subframe are in full load. All of them are in safe range under the condition of no-load hoisting. In the asphalt pavement section of the East Route of Hainan Huandao Expressway, the self-made maintenance equipment is used to carry out the test. The test results show that the self-made maintenance equipment meets the design requirements. Based on the application of early strength cement emulsified asphalt concrete, new technology and matching equipment for rapid maintenance, this paper provides an effective method to solve the problem of rapid pavement repair in high temperature and rainy area of Hainan.
