The TD605M-A type asphalt elongation and elastic recovery standard test mold is a special experimental instrument used to test the elastic elongation properties of asphalt materials, especially emulsified asphalt. It is widely used in highway engineering testing institutions, research institutes, quality supervision departments and asphalt production enterprises.

Asphalt Ductility Test Mold

Model:TD605M-A

I. Product Introduction

This product is designed and manufactured according to the requirements of JTG 3410 "Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering" and references ASTM D113 and AASHTO T 51 international test methods. It is used to prepare standard asphalt elongation and elastic recovery specimens. The mold adopts a standard figure-eight (dumbbell-shaped) structure, ensuring uniform stress during tensile testing and effectively guaranteeing the accuracy and repeatability of test data.

This mold is mainly used for testing the elastic recovery performance of emulsified asphalt under tensile conditions and is one of the important experimental devices for evaluating asphalt flexibility, deformation recovery ability, and road performance.

V. Product Maintenance and Care

To ensure the service life and testing accuracy of the mold, please note the following:

Apply slightly more oil than to the iron mold to facilitate smooth demolding.

After applying oil, place a small piece of waste paper over the small holes to prevent the test material from clogging them.

Clean the mold promptly after each test and store it dry.

Avoid impacts and improper handling to prevent affecting the mold's accuracy.
