【摘要】：近年来,随着我国各类机动车保有量逐年上升,由此产生的废旧橡胶轮胎数量也逐年增多,这必将给环境保护带来越来越大的压力,废橡胶轮胎的处理已受到人们的高度关注。将废旧轮胎橡胶粉再生利用铺筑道路,可以改善道路工程的质量,延长路面的使用寿命,符合我国建设节约型社会、建设生态文明、发展循环经济的国策。本文自主研制一款小型橡胶沥青加工设备,自主研发一种新型环保橡胶沥青,推荐新型环保橡胶沥青混合料间断级配和最佳沥青用量,研究环保橡胶沥青混合料的路用性能及其经济效益,为推广修筑环保橡胶沥青路面提供技术支持。本文自主研制一种小型橡胶沥青加工设备,它包括搅拌装置、加热装置和电控装置。采用本设备加工的橡胶沥青性能良好、质量稳定、符合规范要求,具有全程工艺可控、加热与搅拌一体化、操作方便、搅拌效果好等优点,是一款实用的橡胶沥青加工设备。自主研发一种新型环保橡胶沥青,其特点在于将废旧橡胶粉、废机油循环利用,并加入聚乙烯、氧化锌、4,4’-二硫化二吗啉、芳烃油等改性剂,通过研究各种改性剂占橡胶粉比例,分析橡胶粉掺量和目数对新型环保橡胶沥青性能的影响,提出一种新型环保橡胶沥青的配方。提出了环保橡胶沥青混合料的间断级配设计理论与工程设计方法,选用湿拌法ARHM-13(W)型橡胶沥青混凝土级配作为环保橡胶沥青混合料的级配。采用自主研发的新型环保橡胶沥青为沥青原材料,对3种不同级配的环保橡胶沥青混合料配合比进行优化设计,推荐新型环保橡胶沥青混合料矿料级配和最佳沥青用量。通过比较SMA-13改性沥青混合料和AC-13C普通沥青混合料的路用性能,发现环保橡胶沥青混合料具有良好的高温稳定性能、水稳定性能、低温抗裂性能和抗滑性能。环保橡胶沥青路面低碳环保、寿命成本低、噪音小,路用性能优良,行驶舒适安全,经济和社会效益显著,修筑环保橡胶沥青路面具有广阔的应用前景。
[Abstract]:In recent years, with the increase of the number of various kinds of motor vehicles in China, the number of waste rubber tires is also increasing year by year, which will bring more and more pressure to environmental protection, and the treatment of waste rubber tires has been highly concerned by people.Reusing waste tire rubber powder to build road can improve the quality of road engineering, prolong the service life of road surface, and accord with the national policy of constructing economical society, building ecological civilization and developing circular economy in our country.This paper independently developed a small rubber asphalt processing equipment, independently developed a new type of environmental protection rubber asphalt, recommended the new environmental protection rubber asphalt mixture discontinuous grading and the best asphalt dosage.This paper studies the road performance and economic benefit of environmental protection rubber asphalt mixture, and provides technical support for popularizing and constructing environmental protection rubber asphalt pavement.In this paper, a small rubber asphalt processing equipment is developed, which includes mixing device, heating device and electric control device.The rubber asphalt processed by this equipment has the advantages of good performance, stable quality and accord with the standard requirements. It has the advantages of controllable whole process process, integration of heating and stirring, convenient operation and good mixing effect. It is a practical rubber asphalt processing equipment.A new type of environmental friendly rubber asphalt has been developed, which is characterized by recycling waste rubber powder, waste oil, and adding modifiers such as polyethylene, zinc oxide 4o 4, dimorpholine disulfide, aromatics oil, etc.By studying the ratio of various modifiers to rubber powder and analyzing the influence of rubber powder content and number on the performance of new environmental protection rubber asphalt, a new formulation of environmental protection rubber asphalt was put forward.The discontinuous gradation design theory and engineering design method of environmental protection rubber asphalt mixture are put forward. The wet mix ARHM-13 / W) rubber asphalt concrete gradation is selected as the grading of environmental protection rubber asphalt mixture.Using the new environmental protection rubber asphalt developed by ourselves as the asphalt raw material, three kinds of environmental protection rubber asphalt mixture mixture mix proportion optimization design is carried out, and the new environmental protection rubber asphalt mixture mineral aggregate grading and the best asphalt dosage are recommended.By comparing the pavement performance of SMA-13 modified asphalt mixture and AC-13C common asphalt mixture, it is found that the environmental protection rubber asphalt mixture has good high temperature stability, water stability, low temperature crack resistance and skid resistance.Environmental protection rubber asphalt pavement low carbon environmental protection, low life cost, low noise, good road performance, comfortable and safe driving, significant economic and social benefits, the construction of environmental protection rubber asphalt pavement has a broad application prospects.
