Composite modified emulsified asphalt ultrathin wearing layer and construction method thereof
The invention discloses a composite modified emulsified asphalt ultrathin wearing layer, the thickness of the wearing layer is 5-10mm, and the wearing layer is prepared from the following raw materials: mineral aggregate, cement, emulsified asphalt and water, the mineral aggregate meets the following grading requirements: the mass percentages of the mineral aggregate passing through square hole sieves of 9.5 mm, 4.75 mm, 2.36 mm, 1.18 mm, 0.6 mm, 0.3 mm, 0.15 mm and 0.075 mm are respectively 100%, 80%-93%, 17%-30%, 8%-20%, 6%-14%, 5%-11%, 4%-9% and 3%-7%; the use amount of the cement is 1.5% of the mass of the mineral aggregate, the use amount of the emulsified asphalt is 9.3%-11.7% of the mass of the mineral aggregate, and the use amount of the externally doped water is 2%-3% of the mass of the mineral aggregate. The ultrathin wearing layer disclosed by the invention can be constructed at normal temperature, is thin in paving thickness and has better performance.
本发明公开了一种复合改性乳化沥青超薄磨耗层，该磨耗层的厚度为5～10mm，包括以下原料：矿料、水泥、乳化沥青和水；矿料满足以下级配要求：通过9.5mm、4.75mm、2.36mm、1.18mm、0.6mm、0.3mm、0.15mm和0.075mm方孔筛的质量百分率分别为100％、80％～93％、17％～30％、8％～20％、6％～14％、5％～11％、4％～9％、3％～7％；水泥的用量为矿料质量的1.5％，乳化沥青的用量为矿料质量的9.3％‑11.7％，外掺水的用量为矿量质量的2％‑3％。本发明超薄磨耗层能在常温下施工，加铺厚度薄，且具有较佳性能。
