Full-regeneration RAP refined material ultrathin wearing layer mixture and preparation method thereof
The invention provides a fully-regenerated RAP refined material ultrathin wearing layer mixture and a preparation method thereof, and relates to the technical field of preventive maintenance of pavements. The mixture provided by the invention comprises the following components in parts by weight: 100 parts of mixed aggregate, 3-5 parts of carbon black, 3-5 parts of limestone powder and 7-12 parts of resin, the mixed aggregate comprises a coarse-grade aggregate, an intermediate-grade aggregate and a modified fine aggregate, and the mass ratio of the coarse-grade aggregate to the intermediate-grade aggregate to the modified fine aggregate is (72-50): 20: (8-30); the particle size range of the coarse-grade aggregate is 5-10 mm, the particle size range of the intermediate-grade aggregate is 3-5 mm, and the particle size range of the modified fine aggregate is 0-3 mm. After the coarse-grade aggregate, the intermediate-grade aggregate and the modified fine-grade aggregate are compounded according to a specific proportion, the prepared mixture has high-temperature stability and low-temperature crack resistance, and the comprehensive performance of the wearing layer mixture is improved by improving the grain composition in the mixture.
本发明提供了一种全再生RAP精分料超薄磨耗层混合料及其制备方法，涉及路面预防性养护的技术领域。本发明提供的混合料以重量份数计，包括以下组分：100份的混合集料、3‑5份炭黑、3‑5份石灰岩粉和7‑12份树脂；所述混合集料包括粗级集料、中级集料和改性细集料组成，且所述粗级集料、所述中级集料和所述改性细集料的质量比为(72‑50)：20：(8‑30)；所述粗级集料的粒径范围为5‑10mm，所述中级集料的粒径范围为3‑5mm，所述改性细集料的粒径范围为0‑3mm。本发明通过将粗级集料、中级集料和改性细级集料以特定比例进行复配后，所制成的混合料能够兼具高温稳定性和低温抗裂性能，并通过改善混合料中的颗粒级配，提高磨耗层混合料的综合性能。
