Road construction method
The invention discloses a road construction method, which relates to the technical field of highway pavement construction. The road construction method employs a pavement material prepared from the following raw materials by weight: cement, stone sand, fly ash, water and an additive. The road construction method comprises the following steps: A, building a heat-preserving shed on a construction road section and allowing temperature in the heat-preserving shed to be 20 to 25 DEG C; B, stirring the pavement material in the heat-preserving shed, heating the water to 40 to 50 DEG C, injecting the heated water into a mixer and mixing the water with the cement, the stone sand, the fly ash and the additive under stirring so as to obtain the pavement material; and C, laying the pavement material onto a road pavement, compacting the pavement material, covering the pavement material with a plastic film and covering the plastic film with a heat-insulation layer, wherein covering time is 10 to 15 d. The road construction method is applied to construction in a low temperature environment and overcomes the problems of difficult compaction, too great porosity and too great water permeability coefficient compared with the prior art.
