【摘要】：隨著交通量的增長(zhǎng)、軸載的加重及交通渠化現(xiàn)象，，目前車轍是高速公路主要的破壞形式之一，嚴(yán)重著影響路面的服務(wù)水平；半剛性基層路面早期損壞較普遍，其中之一就是半剛性基層路面的反射裂縫問題，大大降低了道路的使用壽命。另外，強(qiáng)度高、耐沖刷的剛性基層越來(lái)越受到重視，舊水泥混凝土路面加鋪瀝青層的應(yīng)用也越來(lái)越多，但是同樣存在著反射裂縫問題，嚴(yán)重制約著該結(jié)構(gòu)的發(fā)展。為了重點(diǎn)解決瀝青路面的車轍問題及反射裂縫問題，本文開展了大粒徑瀝青碎石的研究。大粒徑瀝青碎石具有良好的抗車轍能力與抗反射裂縫性能，本文在國(guó)內(nèi)外研究成果基礎(chǔ)上，對(duì)級(jí)配類型、改性劑PR摻量因素影響大粒徑瀝青碎石的高溫穩(wěn)定性、水穩(wěn)定性、抗反射裂縫性能及透水性能進(jìn)行對(duì)比分析研究。 本文首先總結(jié)國(guó)內(nèi)外研究，提出對(duì)大粒徑瀝青碎石按照級(jí)配類型及空隙率進(jìn)行分類，主要分為開級(jí)配大粒徑瀝青碎石、半開級(jí)配大粒徑瀝青碎石及密級(jí)配大粒徑瀝青碎石，并確定將OLSM、AM、ATB依次作為研究對(duì)象。根據(jù)3種大粒徑瀝青碎石類型，選取相應(yīng)的礦料級(jí)配范圍，并進(jìn)行集料級(jí)配設(shè)計(jì)。根據(jù)大粒徑瀝青碎石特點(diǎn)，確定改性劑PR摻量為0、0.2%、0.4%。然后進(jìn)行相關(guān)試驗(yàn)分別確定不同級(jí)配類型不同PR摻量的最佳瀝青用量。然后分別確定大粒徑瀝青碎石的高溫穩(wěn)定性、水穩(wěn)定性、抗反射裂縫性能及透水性能的評(píng)價(jià)方法，主要研究級(jí)配類型、改性劑PR摻量因素對(duì)其上述各個(gè)性能影響。最后將3種大粒徑瀝青碎石在不同PR摻量下的路用性能按照提出的評(píng)價(jià)等級(jí)進(jìn)行綜合評(píng)價(jià)。.結(jié)合海文高速試驗(yàn)段所處的氣候條件及交通情況，對(duì)比優(yōu)選出不摻加PR的OLSM-25為最適宜鋪筑的材料。根據(jù)室內(nèi)試驗(yàn)，結(jié)合試驗(yàn)段情況，研究了大粒徑瀝青碎石的施工工藝及施工質(zhì)量控制問題。
[Abstract]:With the increase of traffic volume, the aggravation of axle load and the phenomenon of traffic channelization, rutting is one of the main failure forms of freeway at present, which seriously affects the service level of pavement, and the early damage of semi-rigid base pavement is more common. One of them is the reflection crack of semi-rigid base pavement, which greatly reduces the service life of road. In addition, more and more attention is paid to the rigid base with high strength and erosion resistance, and the application of asphalt overlay on the old cement concrete pavement is more and more, but there is also the problem of reflection crack, which seriously restricts the development of the structure. In order to solve the rutting problem and reflection crack problem of asphalt pavement, the research of large-size asphalt macadam is carried out in this paper. Large-size asphalt macadam has good rutting resistance and anti-reflective crack performance. On the basis of domestic and foreign research results, the factors of gradation type, modifier PR content affect the high temperature stability and water stability of large-size asphalt macadam. The performance of anti-reflection crack and its water permeability were compared and analyzed. This paper firstly summarizes the research at home and abroad, and puts forward the classification of large size asphalt macadam according to gradation type and porosity, which are mainly divided into open gradation large size asphalt macadam, semi open grained large size asphalt macadam and dense grained large size asphalt macadam. OLSMG AMATB was chosen as the research object in turn. According to the three types of large size asphalt macadam, the corresponding gradation range of mineral aggregate is selected and the aggregate gradation design is carried out. According to the characteristics of large size asphalt macadam, the content of modifier PR is determined to be 0 0. 2 and 0. 4%. Then the best asphalt dosage with different PR content was determined by correlation test. Then, the evaluation methods of high temperature stability, water stability, anti-reflection crack performance and water permeability of large-size asphalt macadam are determined respectively. The main research is about the gradation type and the effect of modifier PR content on the above properties. Finally, the road performance of three kinds of bituminous macadam with large particle size under different PR content was evaluated synthetically according to the proposed evaluation grade. According to the climatic conditions and traffic conditions of Haven high-speed test section, OLSM-25 without PR was selected as the most suitable material for paving. According to indoor test and test section, the construction technology and construction quality control of large size asphalt macadam are studied.
