【摘要】：傳統(tǒng)的熱拌瀝青混合料HMA已被廣泛應(yīng)用于道路工程的建設(shè)中,由于其較高的施工溫度,在施工過程中會(huì)釋放出大量的粉塵及CO2等有害氣體,對(duì)環(huán)境造成污染,危害施工人員的身體健康。溫拌瀝青混合料WMA,是通過在瀝青混合料中添加溫拌劑,以實(shí)現(xiàn)降低混合料的拌合與壓實(shí)溫度為目的,但又不損失路用性能的一種新型的道路建筑材料。由于溫拌瀝青混合料的施工溫度相對(duì)較低,所以可以減少大量有害氣體的排放,具有良好的環(huán)保效果。本文的研究在于給中西部地區(qū)溫拌瀝青混合料的施工提供一定的理論指導(dǎo),并推薦適合中西部地區(qū)的溫拌劑。選用降粘型溫拌劑RH與表面活性溫拌劑JY-W1進(jìn)行研究,研究結(jié)論如下:添加RH溫拌劑能夠有效降低SBS改性瀝青的黏度,并使SBS改性瀝青的軟化點(diǎn)與當(dāng)量軟化點(diǎn)分別升高5.8%與0.6%,表明RH溫拌劑提高了瀝青的高溫性能;同時(shí),SBS改性瀝青的延度增長(zhǎng)52.4%,當(dāng)量脆點(diǎn)減小4.7,表明RH溫拌劑改善了瀝青的低溫性能。添加JY-W1溫拌劑后,SBS瀝青的軟化點(diǎn)與當(dāng)量軟化點(diǎn)分別升高9.8%與2.0%,表明JY-W1溫拌劑提高了瀝青的高溫性能;同時(shí),SBS瀝青的延度增長(zhǎng)12.6%,當(dāng)量脆點(diǎn)減小4.0,說明溫拌劑JY-W1有利于瀝青的低溫性能。以馬歇爾標(biāo)準(zhǔn)試件的孔隙率為控制目標(biāo),在達(dá)到與熱拌瀝青混凝土同等壓實(shí)度的前提下,確定RH溫拌瀝青混合料的拌合及壓實(shí)溫度分別為155℃與145℃,JY-W1溫拌瀝青混合料的拌合與壓實(shí)溫度分別為152℃與142℃。與熱拌SBS瀝青混合料相比,添加RH與JY-W1溫拌劑分別降低混合料的拌合與擊實(shí)溫度15℃與18℃。在確定的拌合與壓實(shí)溫度下,對(duì)溫拌瀝青混合料的高低溫性能與水穩(wěn)定性能進(jìn)行了研究。研究結(jié)果表明,與熱拌SBS瀝青混合料相比,添加RH溫拌劑使瀝青混合料的動(dòng)穩(wěn)定度增長(zhǎng)46.08%,浸水馬歇爾穩(wěn)定度MS0與凍融劈裂實(shí)驗(yàn)強(qiáng)度比TSR分別增長(zhǎng)2.75%與2.87%,低溫劈裂抗拉強(qiáng)度與最大彎曲破壞應(yīng)變分別增長(zhǎng)2.19%與60.58%,可見,RH溫拌劑提高了瀝青混合料的高低溫性能與抗水損害能力。添加JY-W1溫拌劑使瀝青混合料的動(dòng)穩(wěn)定度增長(zhǎng)51.41%,凍融劈裂實(shí)驗(yàn)強(qiáng)度比TSR與浸水馬歇爾穩(wěn)定度MS0分別減小1.41%與0.47%,低溫彎曲破壞應(yīng)變與劈裂抗拉強(qiáng)度分別增長(zhǎng)46.44%與1.25%,說明JY-W1溫拌劑提高了瀝青混合料的高低溫性能,對(duì)水穩(wěn)定性能有負(fù)面影響。最后,對(duì)溫拌瀝青混合料的環(huán)保性與經(jīng)濟(jì)性進(jìn)行了分析,結(jié)果顯示,與熱拌SBS瀝青混合料相比,每生產(chǎn)1t瀝青混合料,添加RH、JY-W1溫拌劑可以使CO2排放量分別減少0.73kg/t與0.83kg/t,熱能分別減少0.13×108J與0.16×108J,燃油成本分別降低4.71元和5.78元。同時(shí),摻加RH與JY-W1溫拌劑導(dǎo)致每噸瀝青混合料的造價(jià)成本分別增加25.59元和33.42元。總體來說,兩種溫拌劑各有優(yōu)缺點(diǎn),二者的拌合與壓實(shí)溫度僅存在3℃的差值,擊實(shí)效果均良好。添加RH溫拌劑有利于瀝青的低溫性能、混合料的高低溫性能以及水穩(wěn)性能,而添加JY-W1溫拌劑在改善瀝青的高溫性能、混合料的高溫性能方面比較突出,但對(duì)水穩(wěn)定性能有負(fù)面影響。綜合比選,推薦應(yīng)用RH溫拌劑。
[Abstract]:The traditional hot mix asphalt mixture HMA has been widely used in the construction of road engineering. Due to its high construction temperature, a large amount of dust and CO2 and other harmful gases will be released during the construction process, causing pollution to the environment and endangering the health of the builders. The temperature mixed asphalt mixture, WMA, is added to the asphalt mixture. A new type of road building material, which is used to reduce the mixing and compacting temperature of the mixture, does not lose the road performance. Because the temperature of the mixed asphalt mixture is relatively low, it can reduce the emission of a large number of harmful gases and has good environmental protection effect. The research of this paper is given to the central and western regions. The construction of warm mix asphalt mixture provides some theoretical guidance, and recommends the warm mixing agent suitable for the central and western regions. RH and JY-W1 of surface active warm mixing agent are studied. The conclusion is as follows: adding RH warm mixing agent can effectively reduce the viscosity of SBS modified bitumen, and make the softening point and equivalent softening point of SBS modified asphalt. The increase of 5.8% and 0.6% respectively indicates that the RH warm mixing agent improves the high temperature performance of asphalt; at the same time, the ductility of SBS modified asphalt increases by 52.4% and the equivalent embrittlement point is reduced by 4.7. It indicates that the RH warm mixing agent improves the low temperature performance of asphalt. After adding JY-W1 warm mixing agent, the softening point of SBS asphalt and the equivalent softening point are 9.8% and 2% respectively, indicating that the JY-W1 warm mixing agent is improved. At the same time, the ductility of SBS asphalt increased by 12.6% and the equivalent brittleness point decreased by 4, indicating that the warm mixing agent JY-W1 was beneficial to the low temperature performance of asphalt. The porosity of the Marshall standard specimen was used as the control target and the mixing and compaction temperature of the RH warm mix asphalt mixture was determined on the basis of the same compactness as the hot mixed asphalt concrete. The mixing and compaction temperature of JY-W1 warm mix asphalt mixture at 155 and 145, respectively 152 and 142, respectively. Compared with hot mixed SBS asphalt mixture, adding RH and JY-W1 warm mixing agent to lower the mixing and compaction temperature 15 and 18 degrees, respectively, the high and low temperature properties of the mixture of warm mix asphalt under the determination of mixing and compaction temperature The results show that the dynamic stability of asphalt mixture is increased by 46.08% by adding RH warm mixture, and the experimental strength of Marshall stability MS0 and freeze-thaw splitting is increased by 2.75% and 2.87%, respectively, compared with hot mix asphalt mixture, and the tensile strength and maximum bending failure strain at low temperature are increased respectively. It can be seen that RH warm mixing agent can improve the high and low temperature performance and water resistance ability of asphalt mixture. Adding JY-W1 warm mixing agent makes the dynamic stability of asphalt mixture increase by 51.41%, the experimental strength of freeze-thaw splitting is 1.41% and 0.47%, respectively, and the Marshall stability MS0, respectively, and the fracture strain and splitting tensile strength at low temperature. The increase of 46.44% and 1.25% respectively indicates that JY-W1 warm mixing agent improves the high and low temperature performance of asphalt mixture and has a negative effect on the stability of water. Finally, the environmental protection and economy of the mixture of warm mix asphalt are analyzed. The results show that, compared with the hot mix SBS asphalt mixture, each production of 1t asphalt mixture, adding RH, JY-W1 warm mixing agent can be added. The CO2 emission is reduced by 0.73kg/t and 0.83kg/t respectively. The heat energy is reduced by 0.13 x 108J and 0.16 x 108J respectively. The fuel cost is reduced by 4.71 yuan and 5.78 yuan respectively. At the same time, the cost of each tonne of asphalt mixture is increased by 25.59 yuan and 33.42 yuan respectively by adding RH and JY-W1 warm mixing agent. In general, two kinds of warm mixing agents have their advantages and disadvantages, and two mix and mix. The compaction temperature only has the difference of 3 C, and the effect of compaction is good. Adding RH warm mixing agent is beneficial to the low temperature performance of asphalt, the high and low temperature properties of the mixture and the stability of water, while adding JY-W1 warm mixing agent to improve the high temperature performance of asphalt, the high temperature performance of the mixture is more prominent, but it has a negative effect on the stability of the water. Comprehensive comparison and selection, It is recommended to use RH warm mixing agent.
