PAV-1 Asphalt Pressure Aging System
This system employs high temperature and compressed air within a pressure vessel to accelerate the aging of asphalt, thereby simulating the oxidative aging that occurs during its service life on roads. It is suitable for evaluating the antioxidant aging resistance of different asphalts under specified test temperature and pressure conditions.
SYD-2806H Fully Automatic Asphalt Softening Point Tester
It is suitable for determining the softening point of various types of asphalt, including road petroleum asphalt, coal tar asphalt, and liquid petroleum asphalt, and is the preferred instrument for asphalt manufacturers, highway and bridge construction entities, as well as relevant colleges, universities, and research institutions.
SYD-0654 Emulsified Asphalt–Aggregate Adhesion Tester
It is suitable for testing the adhesion between cationic emulsified asphalt and aggregates, thereby evaluating their resistance to water damage. This instrument features an elegant design, a compact structure, user-friendly operation, and excellent stability, making it the preferred choice for highway and bridge construction agencies, as well as relevant universities and research institutions.
HZ-15 Multifunctional Concrete Core Drilling Machine
It is used in concrete works such as construction projects, highways, airports, ports, and docks. This machine is multi‑functional, capable of both core drilling and cutting and polishing core samples, significantly enhancing work efficiency while reducing equipment investment, making it an ideal instrument for engineering inspection.
SYD-4508G-1 Asphalt Ductility Tester
1. Equipped with an industrial-grade touch screen, featuring advanced technology, high-end design, and excellent performance. 2. Controlled by a 32-bit ARM microcontroller, it automatically regulates the water bath temperature and autonomously acquires and processes tensile and force data.
SYD-0722 Asphalt Mixture Extractor
It is suitable for on-site rapid testing by road construction supervisors, asphalt mixture manufacturers, and construction contractors.
SDL-II Type Concrete Electrical Flux Meter
The electrical‑charge method rapidly assesses concrete permeability by measuring the electric charge passed through the concrete. This approach is suitable for evaluating the permeability of medium‑strength concrete. The equipment is widely used in durability design of concrete structures, mix‑design optimization, and quality‑control and acceptance of construction works.
HG-1000 Concrete Penetration Resistance Tester
It is primarily used to determine the setting time of concrete by measuring penetration resistance. This instrument complies with the GB/T 50080-2002 standard for testing the properties of ordinary concrete mixtures.
DYE-300 Electro-Hydraulic Concrete Flexural and Compressive Testing Machine
This testing machine is suitable for determining the flexural strength of concrete specimens measuring 150×150×550 mm and 100×100×400 mm, as well as the compressive strength of cement mortar and other construction materials. Equipped with electric‑hydraulic loading, load measurement via a transducer, and digital display of force values, it is an essential testing and inspection device for engineering organizations in the construction, materials, highway, and bridge sectors.
Designed by the Cement Institute of the China Building Materials Academy, this is the standard equipment specified in the national standard “Methods for Testing the Strength of Cement Mortar (ISO Method) GB/T 17671-1999,” and is suitable for mixing cement mortar specimens during specimen preparation.
HZ-20 Concrete Core Drilling Machine
This machine is powered by a gasoline engine (an imported original unit) and is equipped with a synthetic diamond‑tipped thin‑walled core drill bit. It is primarily used as testing equipment for concrete and asphalt pavements in applications such as highways, airports, ports, wharves, and dams. The machine can extract cores up to 700 mm deep and is especially suited for high‑grade highways, enabling the extraction of cores from hardened concrete, limestone foundations, and similar materials for compressive and flexural strength testing.
HMP-100 Concrete Finishing Machine
The machine meets the quality requirements for grinding and polishing test specimens as specified in CECO 3, 88, and YBJ 209-86—Technical Specifications for Determining Concrete Compressive Strength by Core Sampling—and complies with the surface‑smoothing standards for test specimens. Consequently, it is widely used on-site for preparing core samples by grinding and polishing.
