The invention discloses a low temperature construction method for a micro-surfacing layer. The low temperature construction method comprises the following steps that (1) raw materials are mixed and stirred, and then are spread on a clean and tidy road surface and compacted; the raw materials comprise, by weight, 100 parts of aggregate, 11-16 parts of SBS modified emulsified asphalt, 3-8 parts of water and 1-3 parts of ordinary portland cement, the temperature of the SBS modified emulsified asphalt during mixing and paving is 25-50 DEG C; and (2) after the SBS modified emulsified asphalt is completely demulsified, compacting and curing are conducted on the micro-surfacing layer, the traffic is opened after the asphalt reaches a certain strength. The low temperature construction method for the micro-surfacing layer is suitable for highway construction and maintenance under low temperature conditions and has been implemented in construction of the Anji Daxi tunnel pavement in Huzhou, Zhejiang province under the ambient temperature of 2 DEG C-10 DEG C, the construction effect of the normal temperature such as 20 DEG C or above is completely achieved, and application requirements are fully satisfied by the performance of the micro-surfacing layer.
