Construction process of curing-free water-stabilized base
The invention discloses a construction technology of a curing-free water-stabilized base. The construction technology comprises the following steps that S1, a lower bearing layer is prepared; s2, measuring and setting out; s3, mixing of the mixed material, wherein the cement stabilized macadam is intensively mixed in a mixing station, and a full-automatic batching stabilized soil mixing machine is adopted as a mixing machine; the mixture comprises a polycarboxylate superplasticizer, a calcium sulphoaluminate expanding agent and an early strength agent; s4, conveying the mixture; s5, paving: continuously paving by a paving machine; if the production capacity of the mixer is relatively low, paving at the lowest speed when the paver is used for paving the mixture, and prohibiting the paver from stopping to wait for the mixture; the paving speed of the paver is generally 1m/min; and S6, rolling compaction: rolling compaction is carried out by following a three-wheel or double-steel-wheel road roller, a vibratory road roller and a pneumatic tire roller behind each paver, and the length of rolling compaction at a time is 50-80 m. According to the invention, the mixture comprises a polycarboxylic acid water reducer, a calcium sulphoaluminate expanding agent and an early strength agent; through the expansion effect of the reagent, the paved pavement can be used without curing.
本发明公开了一种免养生水稳基层施工工艺，包括以下步骤：S1：下承层准备；S2：测量放样；S3：混和料的拌合：水泥稳定碎石在拌和站集中拌合，拌合机采用全自动配料稳定土拌合机；混合料包括聚羧酸减水剂、硫铝酸钙类膨胀剂、早强剂；S4：混合料运送；S5：摊铺：摊铺机宜连续摊铺；如拌和机生产能力较小，在用摊铺机摊铺混合料时，应采用最低速度摊铺，禁止摊铺机停机待料；摊铺机的摊铺速度一般宜在1m/min；S6碾压：每台摊铺机后面，应紧跟三轮或双钢轮压路机，振动压路机和轮胎压路机进行碾压，一次碾压长度为50m～80m。本发明，混合料包括聚羧酸减水剂、硫铝酸钙类膨胀剂、早强剂；通过上述试剂的膨胀作用，无需进行养生，铺设的路面即可使用。
