A telescopic strip for suppressing cracks in pedestrian crossings and its application method and purpose
A technology of telescopic strips and sidewalks, applied in the directions of roads, roads, pavement details, etc., can solve the problems of rarely seen application and continuation of such technologies, the overall strength of pavement slabs, and the poor temperature sensitivity of steel strips. The effect of relieving transverse tension, relieving shrinkage and expansion stress, and strengthening consolidation performance

Embodiment 1
[0018] A stretchable strip, the raw material formula of which is as follows: 100 parts by weight of SBS thermoplastic elastomer, 0.1 part by weight of antioxidant (2,6-tertiary butyl-4-methylphenol), and 0.4 parts by weight of shellac resin. The raw materials are made into stretchable strips with a width of 0.8 cm by conventional polymer processing and molding techniques.
[0019] The application method of the telescopic strip is as follows: the middle and lower layer of the crosswalk is constructed in sections and layers, each section is 15m; the construction is from bottom to top, and the joint width between the two sections is reserved for 0.9cm; the middle and lower layer is completed After construction, insert the telescopic strip into the joint between the section and the section mouth, and finally use one-time construction to complete the construction of the upper layer of the colored asphalt mixture.
Embodiment 2
[0021] A stretchable strip, its raw material formula is as follows: 100 parts by weight of SBR thermoplastic elastomer, 0.2 parts by weight of antioxidant (tetrakis [β-(3,5-tertiary butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester), 0.3 parts by weight of shellac resin. The raw material is made into a stretchable strip with a width of 1.0 cm by using a conventional polymer processing and molding process.
[0022] The application method of the telescopic strip is as follows: the middle and lower layer of the crosswalk is constructed in sections and layers, each section is 18m; the construction is from bottom to top, and the joint width between the two sections is reserved for 1.2cm; the middle and lower layer is completed After construction, insert the telescopic strip into the joint between the section and the section mouth, and finally use one-time construction to complete the construction of the upper layer of the colored asphalt mixture.
Embodiment 3
[0024] A stretchable strip, the raw material formula of which is as follows: 50 parts by weight of thermoplastic elastomer made of SBR, 50 parts by weight of thermoplastic elastomer made of SBS, 0.5 part by weight of antioxidant (dihydroquinoline), and 0.5 part by weight of shellac resin. The raw materials are made into stretchable strips with a width of 1.5 cm by conventional polymer processing and molding techniques.
[0025] The application method of the telescopic strip is as follows: the middle and lower layer of the crosswalk is constructed in sections and layers, each section is 15m; the construction is from bottom to top, and the joint width between the two sections is reserved for 1.7cm; the middle and lower layer is completed After construction, insert the telescopic strip into the joint between the section and the section mouth, and finally use one-time construction to complete the construction of the upper layer of the primary color asphalt mixture.
