Crack stick construction

Anti-crack construction effect

Crack stick

Product introduction

Crack stick (also known as crack stick) is composed of asphalt base polymer, high-strength tensile tire base, high temperature resistance and compatibility with asphalt high-strength compounded fabric. Stick in the cracks or the spalling of the asphalt concrete surface, can reduce and cut off its effect on the temperature shrinkage stress of pavement, thus reduce the reflection crack through the surface of the trend, laying and road because of the isolates abrasion at the grass-roots level and the upper layer, so that the top layer from the effects of multidirectional displacement and the shear stress, for roads, Bridges, airports, etc.

The main performance

1, the isolation effect. Laying crack and the crack surface and asphalt layer isolation, to avoid the direct contact with asphalt layer cracking level, crack tensile stress at the grass-roots level cannot directly transfer the asphalt concrete pavement, reduce the bonding force between the base and surface, but polymer anti-crack stick can enable the lower level very good adhesion into a whole, jointly bear the role of vehicle load, is enough to prevent the interface on the lower level of relative displacement and keep continuous.

2, reinforcement effect. Crack has a certain strength, can absorb a certain amount of tensile stress in the crack, when the crack tensile stress increases and is greater than the crack of tensile strength, crack resistance to deformation, the surface began to crack under the tensile stress in the stick to pass up. Crack stick level will bear all the tensile stress in the crack, crack obviously have the effect of reinforcement, in this sense, it improved the tensile strength of pavement structure layer.

3, energy dissipation cushion. Crack is a certain extensibility of material, high polymer has good low temperature flexibility, laid between the asphalt surface, equivalent to set up an elastic layer, crack tensile stress at the grass-roots level through the anti-cracking polymer spread to a wide range, so as to relieve stress intensity cracks, flexible interlayer can partly tensile energy absorption effect.

4, water seepage control effect. Crack stick seepage-proof layer polymer can form a complete, can partition to the subgrade pavement water penetration, in order to ensure the strength of the base, the base materials properties not deteriorate further. Crack stick for asphalt surface can effectively inhibit cracks propagated up, in the practical engineering play a role of crack resistance of crack and energy absorption effect.

Q:What are the basic principles of civil material selection?
Security: There is no doubt that in the specified period of time, there is a certain quality assurance
Q:What is the relationship between the development of civil engineering and the material and the theory?
There are three major mechanics in civil engineering; theoretical mechanics; material mechanics; structural mechanics. The discovery of mechanics has also reduced the cost of engineering.
Q:The relationship between material development and civil engineering development
The development of civil engineering depends on the development of materials, the application of new materials, reducing the cost of civil engineering costs. Such as the emergence of light steel structure, the emergence of insulation board building energy has been a breakthrough, and so on. There are three major mechanics in civil engineering; theoretical mechanics; material mechanics; structural
Q:Why is material durability so important in civil engineering?
Because the house is not living for a day or two
Q:For the civil engineering students, material mechanics need to grasp to what extent?
Are you civil Material mechanics is the branch of the three major mechanics, of course, important, the design of the basis of the need to clearly grasp the material mechanics, such as the size of the beam design and check these in the engineering practice are directly used, many famous university entrance examination course is material Force rather than knot force can see its importance
Q:The role of materials in civil engineering
The material determines the form of a building or a structure. The material determines the form of the project. For example, the Sui Zhaozhou bridge is made of stone, stone is brittle material, despite the superb design skills, the material determines the span of Zhaozhou Bridge can not be too large, only 30 meters. This is already the stone used in the ultimate bridge! The application of modern high-performance concrete and high-strength steel bar is only possible to make the Hangzhou Bay Bridge, single span of more than 100 meters. The tower is also the case, the brick material of the Wild Goose Pagoda was 58 meters, while the modern material of the Dubai Tower has 818 meters. So the material is to restrict or determine the development of civil engineering.
Q:What is the difference between building materials and civil engineering materials?
The contents of civil engineering materials include green building materials, basic properties of civil engineering materials, air and hard inorganic cementitious materials, cement, concrete, mortar, wall materials and roofing materials, steel and aluminum, wood, asphalt and asphalt mixture Materials, waterproof materials, insulation sound insulation sound insulation materials, building decoration materials
Q:What is the actual state of the bar in civil engineering?
(3) to understand and master the cross-section of the cross-section of the torque, torque diagram; (4) mastery of the straight and straight (2) to understand and master the thin-walled cylinder torsion; (5) master the deformation of the straight rod when the deformation, stiffness conditions; (6) to understand and master the straight rod when the strain energy .4 bending stress symmetrical bending of the The calculation of the concept and the calculation of the beam; the shear force equation of the beam and the moment equation, the shear force diagram and the bending moment diagram; the internal force of the plane frame and the curved rod; the normal stress and the normal stress strength condition on the beam cross- (1) to understand and master the concept of symmetrical bending and beam calculation diagram; (2) master the beam of the shear equation and bending moment equation, the shear force diagram of the shear stress, shear stress strength conditions; (3) to understand and master the plane frame and the internal force of the curved rod; (4) master the beam cross-section of the normal stress, normal stress strength conditions; (5) to understand and master the beam cross-section (6) Understand and master the reasonable design of the beam 5. Displacement of the displacement beam when the beam is bent; Define the differential equation and its integral; Define the displacement of the beam; Nuclear, to improve the stiffness of the beam measures; beam bending energy within the beam.
Q:Characteristics of Modern Civil Engineering Materials
Understand the development trend of civil engineering materials With the development of human civilization and science and technology, civil engineering materials continue to improve and improve. Modern civil engineering, although the traditional soil, stone and other materials have been gradually dominated by new materials replaced. At present, cement concrete, steel, reinforced concrete is an irreplaceable structural material; new alloys, ceramics, glass, organic materials and other synthetic materials, various composite materials in the civil engineering fold occupies more and more important position.
Q:What is the difficulty of civil engineering materials?
Easy to say is easy, are memories of things, but did not learn a few good
