[0002] With the development of transportation, road construction and maintenance are becoming increasingly important. Under low temperature conditions, the durability of roadbed materials directly affects the service life and safety performance of roads. Freeze-thaw resistance test is of great significance for selecting suitable materials and improving road quality. Testing the performance and durability of materials in low temperature environments provides technical support for road construction and maintenance, and improves the service life and safety performance of roads. By conducting freeze-thaw resistance tests on roadbed materials, we can better understand and master the performance characteristics of roadbed materials in low temperature environments, and provide scientific basis and technical support for practical applications.

[0003] In the process of testing the freeze-thaw resistance of different materials, the roadbed materials need to be cast and formed. There are certain limitations in the casting and demolding process, and the operators need to cooperate closely to ensure the uniformity and molding quality of the materials. The molding and demolding process requires a certain amount of time and energy, and the flatness of the casting process will also affect the test results in the later stage, thereby affecting the freeze-thaw resistance of the material. These problems will have an adverse effect on the test results. Therefore, we propose a material freeze-thaw resistance test mold to ensure the accuracy and reliability of the test results.

[0017] When preparing the freeze-thaw resistance test of the roadbed material, select suitable roadbed materials according to the test requirements, determine the appropriate mix ratio, stir and mix the materials to be tested into roadbed material mortar 7, and then prepare the casting mold. First, the baffle 3 is horizontally symmetrically arranged in the inner cavity of the concave plate 1, and one side of the concave plate 1 is limited by the block 2. At the same time, the inner plate 4 is vertically symmetrically arranged on the other side of the baffle 3. The baffle 3 is clamped and fixed by the inner plate 4 and the block 2, and then the bolt 5 is passed through the inner plate 4 to fix it. The baffle 3 and the inner plate 4 form a square groove mold, and then the thick gravel layer 7 is evenly spread in the square groove of the baffle 3 and the inner plate 4, and then the roadbed material mortar 7 is poured on the surface of the thick gravel layer 7, and the stirred roadbed material mortar 7 is poured into the square groove. After the pouring is completed, it is necessary to wait for a period of time for the roadbed material mortar 7 to fully solidify, and then the baffle 3 and the inner plate 4 are removed by reverse operation, and the complete casting test material is slowly pushed out, and the test material slides against the concave plate 1 to complete the mold casting process of the overall roadbed material.

[0018] The upper surface of the baffle plate 3 on one side is symmetrically fixedly connected with a support block 9, and the baffle plate 3 on the other side is the same. A support rod 10 is fixedly connected between the inner walls of the two support blocks 9 on the same side. The outer wall of the support rod 10 is sleeved with a sleeve plate 11.
