How to set the quota for brushing asphalt cold bottom oil in roofing practice?

Refer to the diagram below. <>

Cold base oil. It is with a thinner.

Gasoline, diesel, kerosene.

benzene, etc.). It is mostly used at room temperature for the bottom layer of waterproof projects, so it is called cold bottom oil.

Cold base oil has low viscosity and good flowability. Painted on the substrate surface such as concrete, mortar or wood, it can quickly penetrate into the pores of the base layer, and after the solvent volatilizes, it will be firmly bonded to the substrate. The coating film formed by the cold base oil is relatively thin, and it is generally not used as a waterproof material alone, but only as a supporting material for some waterproof materials.

in the paving of waterproof linoleum.

Previously coated on concrete, mortar, wood and other substrates, it can quickly penetrate into the pores of the substrate, and after the solvent volatilizes, it will be firmly combined with the substrate.

The cold base oil can seal the capillary pores of the base layer and make the base layer form a waterproof ability; The function is to treat the interface of the base layer, so that the asphalt linoleum is easy to pave, so that the surface of the base layer becomes hydrophobic, and creates favorable conditions for bonding similar waterproof materials.

According to the different roof waterproof layers, flat roofs have a variety of methods such as rigid waterproofing, membrane waterproofing, paint waterproofing and powder waterproofing roofing. The membrane waterproof roof is made of multi-layer materials superimposed, and its basic structural level is composed of structural layers and slopes according to the structural requirementsRigid waterproof roof refers to the roof with rigid materials as the waterproof layer, such as waterproof mortar, fine stone concrete, and matching

The layer is brushed with two layers of cold base oil as a binding layer, and one cloth and two oils or two hot asphalt vapor insulation layers are made on the joint layer.

Question 1: How to set the quota of modified emulsified asphalt adhesive layer? Modified emulsified asphalt permeable layer set Beijing budget 2001 quota book VII road 3-46, sticky layer set quota 3-44 subheadings.

The permeable layer is sprinkled on the upper surface of the inorganic material, which mainly plays the role of bonding between the inorganic material and the asphalt concrete on the bottom oil surface, and the adhesive layer mainly plays the role of bonding between the oil surface and the oil surface (a layer of clay oil is sprinkled between the two layers of pavement such as medium particles and fine particles.

Question 2: Which quota is the asphalt sealing layer sleeve for municipal professional road engineering You are looking for emulsified asphalt, corresponding to the specifications and models on the drawings.

Question 3: How to apply the quota of the viscous oil layer of the fuel injection amount Sticky layer:

1), double-layer or three-layer hot-mix hot-paved asphalt mixture pavement before paving the upper layer, the asphalt layer below it has been polluted; 2), pave asphalt layer on the old asphalt pavement or cement concrete pavement;

3) The side of the curb, rainwater inlet, inspection well, etc. in contact with the newly paved asphalt mixture;

Question 4: What quota should be applied to the asphalt lower sealing layer?

Question 5: What quota does the municipal asphalt road generally need to set Asphalt pavement is asphalt concrete, so it is just necessary to distinguish the particle size and ratio of asphalt concrete. There are differences in quotas in different places, and the price should be set according to the design requirements.

Question 6: Does the adhesive layer of the asphalt mixture surface layer refer to the adhesive oil layer The adhesive layer refers to the structural layer used for bonding, of course, the structural layer is very thin, usually only thick. Sticky layer oil refers to the material used as a sticky layer, and the concept of sticky layer is different

Emulsified asphalt, ordinary asphalt, modified asphalt, etc.

Question 7: What is the difference between adhesive layer oil and permeable layer? The viscous layer oil is fast-cracking or medium-cracking emulsified asphalt, modified emulsified asphalt, and fast-cracking or medium-cracking liquid petroleum can also be used;

Permeable oil selects permeable liquid asphalt and emulsified asphalt.

Layered construction can make them expand and contract separately when they encounter thermal expansion and cold contraction, and will not cause serious cracking due to excessive thickness.

Question 8: What is the difference between the oil sealing layer, permeable layer and viscous oil layer of asphalt pavement, and what is the sequence of construction Asphalt pavement design specifications stipulate that above all kinds of bases, permeable asphalt should be set, and above the semi-rigid base, the lower sealing layer should be set, and between the asphalt concrete surface layer, a bright skin sticky layer should be set.

The construction sequence is the permeable layer, the lower sealing layer, and the adhesive layer.

Question 9: What is the difference between petroleum asphalt oil sealing layer, permeable layer and sticky oil layer in road construction? What is the construction sequence of the three?

1.The permeable layer is a thin layer of a certain depth between the asphalt surface course and the non-asphalt material base layer that penetrates the surface of the base layer; Factory. The adhesive layer is a thin layer between the asphalt layer and the asphalt layer; 3.

The sealing layer is a thin layer on the asphalt surface course or base layer that closes the surface void.

Summary. Epoxy coating is equivalent to paint or coating, has two functions, wear-resistant and anti-corrosion, painted on the steel bar to play an anti-corrosion role, painted on the ground is wear-resistant, here because it is the ground, of course, it plays a wear-resistant role.

The primer needs to know the material to determine how to set the sub-item, if it is the same as the material in the middle coat, it is generally the same as the above, and the sub-item does not need to be set separately.

Set of epoxy resin self-leveling floor sub-order, including primer, middle coat and top coat process.

3 Thick epoxy coating; 2. Putty (according to the specific situation, thick C20 concrete trapped shed is dismantled and smoothed with the thick C15 concrete and book; 5. The plain soil is compacted, and the solid coefficient of the jujube is pressed.

Ring rolling talk about oxygen coating is equivalent to paint or coating, there are two for repentance, wear-resistant and anti-corrosion, painted on the steel bar to play an anti-corrosion role, painted on the ground is wear-resistant, here because it is the ground, of course, it plays a wear-resistant role.
