Embodiment 1

[0053] In this embodiment, the FGT resin crack repair material produced by Jiangsu Zhongyitong Road New Material Co., Ltd. is used.

[0054] 1) Evaluation of penetration performance

[0055] Weigh 280g of clean sand with a particle size of 0.3-0.6mm, and put the sand into a cylinder with a cross-sectional area of ​​3.056cm 2 in container 1, see attached figure 1 , the height of the loaded sand sample is h=5.4cm, so that the bulk density reaches 0.017kg / cm 3 , at a height of L cm from the upper surface of the sand sample, slowly pour 80 grams of FGT resin crack repair material. sand, and weigh the uncondensed sand quality as M=150 grams, then the permeability H of the FGT resin crack repair material:

[0056]

[0057] Because H is within the range of 100%≥H≥20% of the specified value, the permeability of the FGT resin crack repairing material used in Example 1 is satisfactory.

[0058] 2) Evaluation of curing time

[0059] First prepare a steel plate with a clean surfac...

Embodiment 2

[0077] In this embodiment, the DS resin crack repair material produced by Jiangsu Changlu Traffic Engineering Co., Ltd. is used.

[0078] 1) Evaluation of penetration performance

[0079] Weigh 280g of clean sand with a particle size of 0.3-0.6mm, and put the sand into a cylinder with a cross-sectional area of ​​3.056cm 2 In the container, the height of the sand sample loaded is h=5.4cm, so that the bulk density reaches 0.017kg / cm 3 , slowly pour 80 grams of DS resin crack repairing material at a height of L cm from the upper surface of the sand sample, such as figure 1 As shown, when the crack repairing material is solidified until it no longer penetrates into the sand sample, take out the sand sample from the container, collect all the uncondensed sand, and weigh the mass of the uncondensed sand as M=120 grams, then the FGT resin crack repairing material The permeability performance H:

[0080]

[0081] Because H is within the scope of the specified value 100% ≥ H ≥ 20...

Embodiment 3

[0101] In this embodiment, the AE resin crack repair material produced by Jiangsu Zhonglu Traffic Science and Technology Co., Ltd. is used.

[0102] 1) Evaluation of penetration performance

[0103] Weigh 280g of clean sand with a particle size of 0.3-0.6mm, and put the sand into a cylinder with a cross-sectional area of ​​3.056cm 2 In the container, the height of the sand sample loaded is h=5.4cm, so that the bulk density reaches 0.017kg / cm 3 , at a height of L cm from the upper surface of the sand sample, slowly pour 80 grams of AE resin crack repair material, such as figure 1 As shown, when the crack repairing material is solidified until it no longer penetrates into the sand sample, take out the sand sample from the container, collect all the uncondensed sand, and weigh the mass of the uncondensed sand as M=100 grams, then the AE resin crack repairing material The permeability performance H:

[0104]

[0105] Since H is within the range of the specified value 100%≥H≥...

Abstract

The invention discloses an evaluation method for the properties of a road resin type crack repair material. The evaluation method comprises the following steps of step 1, evaluating the properties including permeability, solidification time, strength repair ratio and fatigue property recovery rate of the crack repair material; step 2, comparing the permeability, the solidification time, the strength repair ratio and the fatigue property recovery rate which are measured in step 1 to corresponding preset values; and step 3, analyzing a comparison result of step 2, and when the properties all reach a preset value range of the corresponding property index values, determining a total evaluation result of the crack repair material to be qualification, or otherwise determining the total evaluation result to be disqualification. The evaluation method has the beneficial effects that a resin type crack repair material classification property evaluation method and comprehensive evaluation methodare given, and the operability is strong, so that the quality of the road resin type crack repair material is well controlled, and the pavement crack repair quality is ensured to be stable and reliable.

Description

technical field [0001] The present invention relates to the evaluation method of pavement and bridge deck pavement material, especially relate to a kind of test evaluation method of the performance of road resin crack repairing material. Background technique [0002] Crack is one of the main disease forms of materials such as pavement and bridge deck pavement, and it is also the most typical primary disease. Resin material, as a new type of crack repair material, has been widely promoted and applied in the field of pavement crack repair in recent years, and has achieved good results. [0003] The domestic road structure includes the base layer and the surface layer, and the total thickness is relatively thick. According to research and engineering investigations, the surface layer and the base layer are often cracked at the same time, so crack repair materials are required to penetrate from the road surface through the cracks in the surface layer to the cracks in the base la...
