Problems solved by technology

However, when the cement macadam base is compacted, there will be lateral extrusion and movement, resulting in lower side elevations and larger transverse slopes, and the degree of compaction on both sides of the road base cannot be guaranteed.
Often follow-up repairs are required, resulting in a great waste of manpower, materials and machines

Abstract

The invention relates to a cement stabilized macadam base construction method. The method comprises the following steps: S1, preparing a roadbed; S2, surveying and setting out; S3, installing an edgeprotection side form; S4, paving a cement and macadam mixture; S5, performing compaction; and S6, maintaining. The construction method has the effects that the quality of the cement macadam roadbed slope is guaranteed, and the quality of the constructed cement macadam roadbed is guaranteed.

Description

technical field [0001] The present application relates to the field of road construction, in particular to a cement-stabilized gravel base construction method. Background technique [0002] Most of the high-grade highways in my country use cement-stabilized gravel bases. Cement-stabilized crushed stone has good mechanical properties, and its initial strength is high and accompanied by age growth, and its mechanical strength can also be adjusted according to actual engineering needs. Cement-stabilized macadam is characterized by high strength, good water stability, good frost resistance, and erosion resistance. It is an excellent pavement base material. However, cement stabilized macadam materials also have certain shortcomings, mainly because cement stabilized macadam is more brittle, which leads to strong sensitivity to humidity and temperature, and it is easy to cause cracks due to changes in temperature and humidity and reflect to the road surface, resulting in The stre...
