【摘要】：隨著我國(guó)公路養(yǎng)護(hù)高峰的即將來(lái)臨，深入研究瀝青路面再生技術(shù)，對(duì)保護(hù)生態(tài)環(huán)境、提高資源利用率、降低公路建設(shè)成本具有重要的意義，同時(shí)，促進(jìn)公路事業(yè)的可持續(xù)發(fā)展。本文在基于國(guó)內(nèi)外瀝青再生技術(shù)深入研究的基礎(chǔ)上，選用廠拌熱再生技術(shù)，研究廠拌熱再生技術(shù)的適用性和廠拌熱再生瀝青混合料的路用性能。 本文針廠拌熱再生技術(shù)的特點(diǎn)進(jìn)行研究，從組分遷移理論和相容性理論對(duì)老化瀝青的再生機(jī)理進(jìn)行分析，分析再生劑的性能要求與指標(biāo)標(biāo)準(zhǔn)，并對(duì)再生劑與瀝青的配伍性進(jìn)行深入研究。在此基礎(chǔ)上，從再生瀝青標(biāo)號(hào)、再生料摻量、最佳瀝青用量和再生瀝青混合料級(jí)配等關(guān)鍵點(diǎn)入手，，確定廠拌熱再生瀝青混合料的配合比設(shè)計(jì)。結(jié)合試驗(yàn)路鋪筑，系統(tǒng)分析了再生劑與舊瀝青適應(yīng)性、舊瀝青混合料的變異性與離析、拌和溫度、拌和時(shí)間、再生劑摻和工藝對(duì)廠拌熱再生瀝青混合料的影響，提出了廢舊瀝青混合料廠拌熱再生的質(zhì)量控制要點(diǎn)和施工工藝。 結(jié)合工程需求，提出再生劑的性能要求，瀝青再生試驗(yàn)結(jié)果表明，采用外摻法，摻量為11%的再生瀝青技術(shù)指標(biāo)能夠滿足規(guī)范對(duì)70#A級(jí)瀝青的技術(shù)要求。結(jié)合再生瀝青混合料的路用性能試驗(yàn)，得出：隨著舊料摻量的增加，再生瀝青混合料的水穩(wěn)定性能和低溫抗裂性能變差，高溫穩(wěn)定性隨著舊料摻量的增加，先增大后減小，40%左右，高溫穩(wěn)定性能最佳。通過(guò)試驗(yàn)路進(jìn)行驗(yàn)證，再生瀝青混合料的路用性能均能滿足施工規(guī)范要求。
[Abstract]:With the coming of the highway maintenance peak in China, it is of great significance to study the asphalt pavement regeneration technology to protect the ecological environment, improve the utilization of resources and reduce the cost of highway construction. In order to promote the sustainable development of highway industry, based on the in-depth research of asphalt recycling technology at home and abroad, this paper selects the hot recycling technology. The applicability of hot recycling technology and the road performance of hot recycled asphalt mixture were studied. In this paper, the characteristics of heat regeneration technology for needle mill were studied. The regeneration mechanism of aging asphalt was analyzed based on component migration theory and compatibility theory, and the performance requirements and index standards of regenerating agent were analyzed. On the basis of this, the key points such as the grade of recycled asphalt, the amount of recycled mixture, the optimum amount of asphalt and the gradation of recycled asphalt mixture are studied. The mix ratio design of hot recycled asphalt mixture was determined. The adaptability of recycled agent and old asphalt, the variability and segregation of old asphalt mixture, mixing temperature and mixing time were systematically analyzed in combination with the paving of test road. The influence of the mixing technology of regenerative agent on the reclaimed asphalt mixture is discussed. The quality control points and construction technology of the waste asphalt mixture are put forward. According to the engineering requirements, the performance requirements of the regenerating agent are put forward. The test results of asphalt regeneration show that the admixture method is adopted. The technical specifications of recycled asphalt with the content of 11% can meet the technical requirements of 70 #A grade asphalt. Combined with the road performance test of recycled asphalt mixture, it is concluded that: with the increase of the amount of used materials. The water stability and low temperature crack resistance of recycled asphalt mixture become worse. The high temperature stability increases first and then decreases about 40% with the increase of the amount of used materials. The high temperature stability is the best. The road performance of recycled asphalt mixture can meet the requirements of construction code.
