CRTS Ⅱ type slab track plate joint from the seam between the wound repair methods

CRTS Ⅱ type slab track plate between the joint seam from a wound repair method, repair materials CRTS Ⅱ type plate without a frantic jumble track plate width between joints of concrete and the seam track plate from wound repair appropriate USES organic silicone material, its performance should meet the requirements of schedule 16-1. Wide joints and track plate away from the seam repairing concrete material performance demands the schedule number 16-1 unit projects detection method 1 table dry time min 45 gb/T134772 stick (or less Curing) Time h flow 33 degrees or less mm04 elastic recovery rate % 805 tensile modulus of 23 ℃ or higher MPa 0 or less. 3 - 20℃≤0. 36 stretching quantity ( - 10℃） 657 mm or greater and loss of concrete bonding area of bonding area is not greater than 20%, colloid cohesion have local failure 8 MPa 0 or less tensile strength without treatment. Thermal aging (4 80℃，168h） ≤0. 8 ultraviolet ( 300W，168h，41℃） ≤0. 8 flooding ( 4 d) ≤0. 49 elongation without % 400 thermal aging (or 80℃，168h） P 300 ultraviolet ( 300W，168h，41℃） P 300 flooding ( 4 d) 40010 or higher mass loss % 6 or less note: GB/T13477 building sealing material test method 2, the main repair machines manually grouting machine, steel wire brush, vacuum cleaner, etc. Third, repair procedure 1. Using a wire brush, vacuum cleaner clean from inside the seam sundry, such as cracks and maintain the internal dry. 2. Use the tools such as shovel to press the organic silicon resin repair material into leave seam within 20 mm above. 3. After being curing repair materials, surface finishing, cleaning the scene. Four, the environmental requirements construction optimum temperature 5 ~ 30 ℃, snow and rain day construction is not allowed.
