Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: during construction in winter, due to the low temperature, the heat loss of the road is fast, which makes the water stabilization layer dry slowly, which easily affects the strength of the water stability layer, resulting in a decline in road quality

Abstract

The invention relates to a winter road construction method, and relates to the field of road construction, the winter road construction method comprises the step of laying of a cement stabilizing layer, and the step of laying of the cement stabilizing layer comprises the substeps of cement stabilizing layer laying preparation, cement mixing, cement paving and leveling, cement stabilizing layer rolling and cement stabilizing layer heat preservation maintenance. The thermal insulation maintenance of the cement stabilizing layer refers to laying a thermal insulation piece on the cement stabilizing layer by adopting a thermal insulation piece laying device. The thermal insulation layer is laid on the cement stable layer, so that the loss of heat on the road is reduced, the drying of the cement stable layer is accelerated, the influence of temperature on the strength of the cement stable layer is reduced, and the purpose of improving the road construction quality is achieved.

Description

technical field [0001] The present application relates to the field of road construction, in particular to a winter road construction method. Background technique [0002] The road is the infrastructure for all kinds of trackless vehicles and pedestrians. [0003] In related technologies, such as the Chinese patent with the publication number CN108755319A, a road construction method is proposed, which includes the following steps, S1: excavating a foundation pit for pipeline placement on the soil roadbed; S2: laying geotextiles in the foundation pit, geotextiles Both ends of the foundation pit are exposed; S3: choose to place the support plate or place the pipeline directly according to the type of pipeline; S4: fill the foundation pit with yellow sand, the yellow sand will cover the pipeline, and then tamp the yellow sand; S5: pour the yellow sand Lay the backfill intermittently on the ground, and tamp the backfill after each laying until the backfill is flush with the ope...
