What is the specific given cement stabilized macadam layer per meter? The following proportions of cement are for reference:

P.o42.5 dose: 107kg.

Stone powder: General dosage: 1050kg.

Gravel: 5-3 1.5 continuous grading dosage: 1087kg.

Water: 63 kg

Matters needing attention in calculation:

1, the strength of cement stabilized macadam layer (cement dosage) is given by the design unit.

2. The mixture ratio of cement stabilized macadam layer shall be determined by the laboratory according to the design requirements combined with specific materials.

3. The mixture ratio of cement stabilized macadam layer on the construction site shall be subject to the material grading table issued by the laboratory.

4. It should be noted that the mixture ratio of cement stabilized macadam is the weight ratio. The strength designed by the design unit generally only represents the percentage of cement consumption (that is, xx% water-stable materials).

Matters needing attention in the construction of water-stable layer:

1, the water-stable mixture ratio should be mixed in the laboratory in advance to determine the cement content and the proportion of coarse and fine aggregate. At the same time, determine the maximum dry density. When the equivalent is large, water can be added to the stable mixing station to improve the efficiency. ?

2, can use artificial, grader and paver construction methods, before the initial setting of cement, with roller to achieve the design degree of compaction. After the construction is completed, water should be sprinkled to keep the water stable.

3. Before the construction of the water-stable layer is started, but the asphalt structure layer is not paved, the construction site between the adjacent sections such as unfinished special bridges, long tunnels and special geological sections should build the transport access road by itself, and the sections that have been handed over to the subgrade should not be used as construction passages.

4. The left and right construction of the water-stable layer of the same road section should be staggered. In layered construction, the construction of the other half should be started after the continuous construction of the first and second floors is completed and maintained in place.

5. After each section of rolling is completed and passes the compaction inspection, the curing shall be started immediately. When the asphalt is diluted with kerosene, it should be sprayed in time after the water-stable layer is covered with geotextile for 3~4 days, and the traffic can only be opened after the construction of the lower seal layer is completed and the water-stable layer reaches the strength of 7 days.
