Anonymous users2024-02-11As long as there is no effect on compaction, it is possible to fill the thickness in the second layer, and if the additional layer cannot be compacted, it must be compacted in two times.
I hope my answer can help you.

If it is too small (less than 12 13cm), the water-stabilized layer cannot form a structural layer, and it is easy to cause problems when paving and compaction; It should not be too large (more than 22 25 cm), too large paving may be fine, and compaction may not meet the requirements. The minimum thickness should be greater than or equal to 12 cm.
Hydraulic stabilized layer is the abbreviation of cement stabilized gravel layer, cement stabilized gravel layer is graded gravel as aggregate, using a certain amount of cementitious material and sufficient mortar volume to fill the void of aggregate, according to the principle of embedded extrusion paving and compaction. Its compaction is close to compactness, and its strength mainly depends on the principle of intercalation and locking between the gravel, and at the same time, there is enough mortar volume to fill the voids of the aggregate. Its initial strength is high, and the strength increases with the age and quickly forms a plate, so it has high strength, impermeability and frost resistance.
The amount of water-stabilized cement is generally 3% 6% of the mixture, and the unconfined compressive strength can be reached in 7 days, which is higher than that of other subgrade materials. After the water is stable and survives, it is not muddy in the rain, and the surface is solid, which is an ideal base material for high-grade pavement.

Anonymous users2024-02-07If the compaction of the water-stabilized layer is not enough, it must be reworked: within 6 hours of paving, the pressure can be supplemented. After six hours, it had to be dug up and reworked.
First of all, the normal construction should be the acceptance of the lower structural layer before continuing to carry out the construction of the upper structural layer. It is necessary to collect the qualification and then carry out the next work is also to reduce economic losses, you only need to rework one layer of structure, but now Mu Xun has to rework the structure of two or even three layers late, which is a waste of money and resources. Therefore, we must strictly follow the design requirements and construction requirements in the construction process, if we find that there are inconsistencies in the construction drawings on the site, we must contact the designer in time and respond to Party A, so as to solve the problem in time and avoid some unnecessary losses.

The water in the thermos pot is not drinkable the next day because the overnight boiled water contains nitrite. Some experts have found that the nitrite content in boiled water is higher than that in raw water. Moreover, the nitrite content of boiling water that has been boiled for too long or more than 24 hours has been boiled for many times.
On September 30, Niralta finally renewed the second layer, after entering, there were three stones inside, on which there were four pendants, the second in the upper left corner was true, with which the largest stone was broken, so that it became two, put the four stones in the square under the compass, and open the pull. The password of the potato number is in four places, the first password is a note on the sofa, the second is the card on the ground, then the mirror on the wall, click on him, the third is the password, the fourth is in the diary, turn a few pages, what Ram said. There is a hammer in the tower, and there is a hammer to point the largest stones, smash the stones, and then put them on the square.
