Special sealing material for asphalt pavement water seepage detection and preparation method thereof

Abstract

The invention discloses a special sealing material for asphalt pavement water seepage detection and a preparation method of the special sealing material, and the special sealing material for asphalt pavement water seepage detection comprises the following raw material components in parts by mass: 45-55 parts of a calcium-based lubricating grease, 20-30 parts of talcum powder and 20-30 parts of graded machine-made sand. The special sealing material for asphalt pavement water seepage detection can be used for preparing sealants with different thicknesses according to field conditions, and is convenient to operate; the contact part of the pavement and the water seepage instrument can be well filled and bonded, and the sealing effect is enhanced; repeated utilization can be achieved, and costis saved; after using, the materialcan be shoveled away from the road surface using a small sholve without polluting the road surface; the special sealing materialcan be stored and used for a long time and can be used as required, and the test success rate is greatly improved.

Description

technical field [0001] The invention relates to a special sealing material for asphalt pavement water seepage detection and a preparation method thereof, belonging to the field of sealing materials for road surface water seepage detection. Background technique [0002] In the quality inspection of asphalt pavement, water seepage is an important inspection index. In the existing detection methods, the sealing material used is generally putty or plasticine. However, in practice, it is found that the existing sealing materials have the following problems: 1) poor controllability of thickness, not easy to press or knead; 2) poor adhesion to the road surface, which often leads to failure of experiments and wastes a lot Materials and time; 3) It cannot be reused, it will become a very thin paste when it meets water, it cannot be used for the next test, and it will solidify after drying, so it can only be discarded; 4) It needs on-site configuration, which is poor in convenience; ...

Problems solved by technology

However, in practice, it is found that the existing sealing materials have the following problems: 1) poor controllability of thickness, not easy to press or knead; 2) poor adhesion to the road surface, which often leads to failure of experiments and wastes a lot Materials and time; 3) It cannot be reused, it will become a very thin paste when it meets water, it cannot be used for the next test, and it will solidify after drying, so it can only be discarded; 4) It needs on-site configuration, which is poor in convenience; 5) It is very troublesome to use putty as a sealing material. It needs to be prepared before each use, and it is not easy to operate and easily pollutes the road surface; 6) The cost of plasticine is too high to be reused, which increases the cost of testing, and it is not easy to integrate with the road surface. Bonding, the composition is relatively dense, and the sealing effect is poor, resulting in a low test success rate
