【摘要】：透水性瀝青路面具有減少水霧和眩光、降低噪聲、抗滑性好等優(yōu)點,近年來引起道路工作者的廣泛關(guān)注。由于透水性瀝青路面空隙率大,所以其混合料的必須使用粘度高的高粘改性瀝青。高粘改性瀝青質(zhì)量的優(yōu)劣直接影響透水性瀝青路面的性能,所以制備出性能優(yōu)異的高粘改性瀝青對提高透水性瀝青路面性能至關(guān)重要。本文通過室內(nèi)試驗,以Singapore殼牌70#瀝青為母體瀝青,利用SBS、廢橡膠粉和萜烯樹脂對其改性制備高粘改性瀝青。研究了SBS、廢橡膠粉和萜烯樹脂不同摻量對高粘改性瀝青的軟化點、針入度、延度和60℃粘度的影響規(guī)律,從而確定各改性劑的的最佳摻量,制備出適用于透水性瀝青路面的高粘改性瀝青。選用SINOTPS高粘改性瀝青、RMC高粘改性瀝青和殼牌高粘改性瀝青作為對照組,通過針入度指數(shù)和針入度粘度指數(shù)對四種高粘度改性瀝青的感溫性能進行研究,試驗結(jié)果表明自主研制高粘改性瀝青的溫度敏感性最低。采用RTFOT老化試驗對四種高粘度改性瀝青的老化性能進行研究,老化后四種高粘改性瀝青的針入度和延度降低,60℃粘度增大。采用動態(tài)剪切流變試驗對四種高粘度改性瀝青的原樣及RTFOT老化后試樣的流變性能進行研究,結(jié)果表明自主研制的高粘改性瀝青具有良好的高溫性能。以20%的空隙率為目標(biāo)空隙率,確定了2.36mm篩孔的通過率為12%,從而確定了OGFC-13的礦料級配。利用析漏試驗和飛散試驗確定四種高粘改性瀝青混合料的最佳油石比。研究了四種高粘改性瀝青混合料的高溫穩(wěn)定性、低溫抗裂性、水穩(wěn)定性、抗滑性、滲水性。結(jié)果表明,四種高粘改性瀝青混合料都能滿足透水性瀝青路面的技術(shù)要求,且自主研制高粘改性瀝青混合料的綜合性能更為突出。
[Abstract]:The permeable asphalt pavement has reduced water mist and glare, reduce noise, anti slide advantages, attracted wide attention in recent years. Because the road workers of permeable asphalt pavement void, so the mixture must use high viscosity high viscosity modified asphalt. The high viscosity modified asphalt quality directly influence of the performance of the permeable asphalt pavement, so preparing excellent high viscosity modified asphalt to improve the permeability of asphalt pavement is very important. Through the test, the Shell Singapore 70# as the matrix asphalt asphalt, using SBS, waste rubber powder and terpene resin to prepare high viscosity modified asphalt. Study on the SBS penetration softening point of modified asphalt and high viscosity of waste rubber powder and terpene resin with different content, extension of influence degree and 60 degrees of viscosity, so as to determine the best modifier with the amount of preparation for water Asphalt pavement of high viscosity modified asphalt. Using SINOTPS high viscosity modified asphalt, RMC modified asphalt and Shell high viscosity high viscosity modified asphalt as the control group, the penetration index of penetration and viscosity index research of four kinds of high viscosity modified asphalt temperature properties, experimental results show that the developed high viscosity modified asphalt. The lowest temperature sensitivity by RTFOT aging test research on four types of high viscosity modified asphalt after aging aging performance, four kinds of high viscosity modified asphalt penetration and ductility decrease of 60 DEG C, the viscosity increases. The dynamic shear rheological tests on rheological properties of samples and the original RTFOT four kinds of high viscosity modified asphalt after aging research, results show that the self-developed high viscosity modified asphalt has good high-temperature performance. As the goal to 20% voidage voidage, determined by the rate of 2.36mm mesh is 12%, which is The gradation of OGFC-13. Using the leak test and cantabro test to determine four kinds of optimum asphalt high viscosity modified asphalt mixture ratio. Four kinds of high temperature stability and high viscosity modified asphalt mixture, low temperature crack resistance, water stability and skid resistance, water permeability. The results showed that four high viscosity modified asphalt mixture can meet the requirements of permeable asphalt pavement technology, and developed the comprehensive performance of high viscosity modified asphalt mixture is more prominent.
