Ultrathin asphalt mixture based on environment-friendly rubber powder and preparation method thereof
The invention relates to an ultrathin asphalt mixture based on environment-friendly rubber powder and a preparation method thereof. The ultrathin asphalt mixture comprises the following components inparts by weight: 80-95% of aggregate, 4-10% of mineral powder, 0.1-0.6% of fibers and 4-8% of environment-friendly rubber powder modified asphalt. The grading type of the aggregate is improved AC-10,and the ratio of the environment-friendly rubber powder to the matrix asphalt in the environment-friendly rubber powder modified asphalt is 0.05-0.40. The ultrathin asphalt mixture based on the environment-friendly rubber powder prepared by the invention is excellent in comprehensive performance; the anti-rutting performance, the high-temperature performance, the water damage resistance, the mechanical property, the durability and other use performance are greatly improved, and the ultrathin asphalt mixture has the advantages of excellent low-temperature performance, high self-cohesiveness, good water seepage resistance, high cost performance, small harm to health of construction operators and high environmental friendliness. The thickness of the prepared environment-friendly rubber powderultrathin asphalt pavement can be 1.5-3.5 cm, the construction cost is remarkably reduced, the cost can be saved by 20% or above, the vehicle running noise is reduced, the cost performance is high, and the ultrathin asphalt mixture has wide market application prospects.
本发明涉及一种基于环保橡胶粉的超薄沥青混合料及其制备方法，该超薄沥青混合料包括如下重量份组分：集料80‑95％、矿粉4‑10％、纤维0.1‑0.6％和环保橡胶粉改性沥青4‑8％；其中，集料的级配类型为改进型AC‑10，环保橡胶粉改性沥青中环保橡胶粉和基质沥青的比例为0.05‑0.40。本发明制得的基于环保橡胶粉超薄沥青混合料综合性能优异，抗车辙性能、高温性能、抗水损害性能、力学性能、耐久性等使用性能大幅度提高，具有优良的低温性能，自身粘聚性强，抗渗水性好，性价比较高，对施工作业人员健康危害小，环境友好性高。由此制得的环保橡胶粉超薄沥青路面的厚度可为1.5‑3.5cm，显著降低工程造价，成本可节约20％以上，降低车辆行驶噪声，性价比高，具备广泛的市场应用前景。
