HTLB-3B intelligent pavement interlayer adhesion pull-out tester

Product Information

The study of the characteristics of interlayer bonding materials in asphalt pavement structures has been a hot research topic both domestically and internationally in recent years. If the tensile and shear strength of the asphalt surface layer is insufficient, it is prone to pavement damage such as displacement, rolling, and rutting. The various corresponding experimental equipment developed by various units cannot adapt well to the on-site working environment. After carefully researching the on-site working environment and customer feedback, our company has developed a brand new complete set of pavement interlayer bonding strength testing equipment. Compared to other products on the market, it is lightweight and easy to use, with a built-in axial loading mechanism (no need for a jack or reaction frame during on-site testing). The device comes with a built-in power lithium battery pack, without the need for a generator or onboard battery, and can undergo no less than 30 continuous tests under full charge conditions. The device comes with a 5-inch color display screen, a user-friendly interface, and a self-developed load control algorithm with high measurement accuracy. There is no abnormal noise when the motor is running, and it has upper and lower limit protection and overload protection functions during operation. The equipment has the characteristics of saving experimental data and exporting data, and both in terms of functionality and configuration, it surpasses similar products in the market.
