Paving construction method of asphalt overlay
The invention relates to the technical field of asphalt construction, in particular to a paving construction method of an asphalt overlay. The method comprises the following steps: 1) paving a first mixture on the surface of the asphalt pavement, wherein the first mixture is obtained by mixing waterproof modified asphalt and filler; the waterproof modified asphalt is prepared from the following components in parts by weight: 60 to 95 parts of matrix asphalt, 20 to 30 parts of SBS (Styrene Butadiene Styrene) rubber, 10 to 20 parts of glass fiber felt, 10 to 20 parts of hydroxypropyl acrylate, 5 to 10 parts of maleic anhydride grafted polypropylene and 5 to 10 parts of EVA (Ethylene Vinyl Acetate), (2) rolling the first mixture to obtain a waterproof layer with the thickness of 0.5-1 cm; 3) paving a second mixture on the surface of the waterproof layer, wherein the second mixture is obtained by mixing matrix asphalt and fine aggregate; and (4) rolling the second mixture to obtain the wearing layer with the thickness of 1.5-2cm.
本发明涉及沥青施工技术领域，具体而言，涉及一种沥青罩面的摊铺施工方法。该方法包括1)在沥青路面表面摊铺第一混合料，所述第一混合料由防水改性沥青和填料混合得到；所述防水改性沥青以重量份计，包括基质沥青60～95份、SBS橡胶20～30份、玻纤毡10～20份、丙烯酸羟丙酯10～20份、马来酸酐接枝聚丙烯5～10份以及EVA 5～10份；2)碾压所述第一混合料得到0.5cm～1cm的防水层；3)在所述防水层表面摊铺第二混合料，所述第二混合料由基质沥青与细集料混合得到；4)碾压所述第二混合料得到1.5cm～2cm的磨耗层。
