In the landscape of modern pavement engineering, the Emulsified Bitumen Cohesion Adhesion Tester stands as a critical tool for ensuring the longevity and safety of slurry seal and micro-surfacing applications. As a premier supplier, Xi'an Zealchon Electronic Technology Co., Ltd. integrates over 15 years of deep-sector experience to provide "Information Gain" that transcends standard specifications.
Standardized by ASTM D3910 and ISSA (International Slurry Surfacing Association), the cohesion test determines the torque value required to shear a specific cured sample of emulsified asphalt mixture. This metric is not merely a number; it is a predictor of the "Set Time" and "Traffic Time," allowing contractors to minimize road closure durations while maximizing structural durability.
Utilizing CNC lathes, milling machines, and argon arc welding to ensure every tester meets sub-millimeter tolerances.
Developed in collaboration with Chang'an University Highway College, bridging theoretical research with field application.
Deployed by government agencies and commercial labs worldwide, from the humid tropics of SE Asia to the heat of the Middle East.
Our "Xiya" trademark is recognized for filling critical gaps in pavement testing instruments with provincial-level accolades.

Proprietary Testing Instruments
Standards Compliant & Certified
The global road maintenance industry is pivoting towards Sustainable Infrastructure. Emulsified bitumen, being cold-mixed, significantly reduces carbon emissions compared to hot-mix asphalt. Our technical roadmap focuses on:
As a leading supplier and pricelist provider, we ensure that our hardware is not just a purchase but an investment in future-proof data reliability.
Developed nations are shifting from "New Construction" to "Asset Management." Our testers facilitate precise preventative maintenance, extending road life by 5-10 years.
We provide region-specific calibration services, ensuring compliance with local transport authority mandates in Europe, North America, and beyond.
Located in Xi'an, the heart of Chinaβs high-tech manufacturing, we leverage rapid prototyping and efficient logistics to reduce lead times by 30% compared to Western counterparts.
It identifies the "quick-set" properties of the mixture. Without an accurate cohesion tester, traffic may be allowed on the road too early, causing aggregate loss and surface failure.
Each unit undergoes a multi-point calibration process against certified standards. Our cooperation with top engineering universities ensures our torque sensors are of laboratory grade.
Depending on customization (e.g., specialized voltage, digital export modules), standard lead times range from 2 to 4 weeks, backed by our efficient Xi'an logistics hub.
Yes, we offer comprehensive digital support, including video training and remote technician assistance, as well as on-site commissioning for large-scale laboratory setups.
