Paving construction method for large-thickness wide-width water stable layer
The invention discloses a paving construction method for a large-thickness wide-width water stable layer, relates to the technical field of civil engineering, and aims to solve the problems of low interlayer adhesion degree, infirm adhesion, poor integrity, easiness in cracking under heavy load, need of a large amount of construction time and low paving efficiency in layered paving in the prior art. The method is characterized by comprising the following steps that S1, the weight ratio of graded gravel to cement in a cement stabilized gravel lower base layer is 100: 4.7, the maximum dry density is 2.399 g/cm < 3 >, the optimal water content is 5.3%, and the grain size ratio of the graded gravel is 16-31.5 mm: 9.5-19 mm: 4.75-9.5 mm: 0-4.75 mm: 27%: 29%: 16%: 28%; S2, the weight ratio of graded gravel to cement in a base layer of the cement stabilized gravel is 100: 5.7, the maximum dry density is 2.421 g/cm < 3 >, the optimal water content is 5.6%, and the particle size ratio of the graded gravel is that 1631.5 mm: 9.519 mm: 4.759.5 mm: 0-4.75 mm = 31%: 26%: 18%: 25%; S3, surveying and setting out; S4, constructing a lower base layer of the cement stabilized gravel; S5, constructing a base layer in the cement stabilized gravel; and S6, performing maintenance and finished product protection.
