Asphalt electric heating scraper, electric heating roll‑material scraper, electric heating scraper—available in stock.
The pendulum tester is a dynamic pendulum‑impact type instrument. It was developed based on the fundamental principle that “the loss of potential energy of the pendulum equals the work done to overcome friction between the rubber pad mounted at the end of the pendulum arm and the road surface as it slides along it.”
I. Product Overview The dimensional stability testing apparatus for base materials used in asphalt waterproofing membranes is manufactured in accordance with GB/T 18840-2002 “Base Materials for Asphalt Waterproofing Membranes” and is intended for conducting thermal dimensional stability tests on such base materials. II. Main Technical Parameters 1. Gripper clamping width: 100 mm, equipped with a hook. 2. Total mass of the lower gripper and counterweight for Type I products: 3000 g. 3.

LYY-8 Type Asphalt Ductility Tester
The low-temperature asphalt ductility tester is suitable for measuring the ductility of asphalt and liquid asphalt distillation residues, as well as evaporative residues from asphalt emulsions, across various specifications and grades. It is widely used in manufacturing, road construction, and research institutions, particularly for testing modified asphalts, and complies with the JTG E20‑2011 standard.
Asphalt Flash and Fire Point Tester, Cleveland Open Cup Apparatus
It employs a furnace design to ensure test safety; the heating power is continuously adjustable, meeting the requirements of the experiment.
Sample weight: 4500 g; recommended sample weight: 1000–1500 g
Fully Automatic Asphalt Extractor
It is primarily used for determining the asphalt content (or asphalt-to-aggregate ratio) in asphalt mixtures prepared with viscous petroleum asphalt via centrifugal separation, and can also perform preliminary aggregate grading. It is suitable for assessing the quality of commercial asphalt during pavement construction and for measuring the asphalt content in both asphalt and asphalt mixtures during condition surveys of existing pavements. This equipment is essential for construction firms, testing laboratories, research institutions, and educational establishments in the highway transportation sector.
Reinforcement bending testing machine
The rebar bending testing machine is specialized equipment used for conducting cold-bending tests as well as flat‑face and reverse‑face bending tests on reinforcing steel. Its principal technical parameters comply with the requirements of GB/T 1499.2-2018 “Steel Bars for Reinforced Concrete—Part 2: Hot‑rolled Ribbed Steel Bars,” YB/T 5126-2003 “Test Procedure for Flat‑Face Reverse Bending of Steel Bars,” and ISO 10065:1990 regarding the specifications and requirements for cold‑bending tests and flat‑face reverse‑bending tests.
