Product Description
Cold-mix asphalt mixture is a new type of road material, which has the advantages of simple construction, environmental protection and energy, and is gradually attracting the attention of road construction projects.This paper aims to discuss the feasibility and application prospect of cold-mix asphalt mixture in road construction by studying its performance test and application.
Purpose and method of performance test of cold-mix asphalt mixture
The purpose of the performance test of cold-mix asphalt mixture is to evaluate its feasibility and applicability in road construction by testing its performance indexes.The main performance indexes include shear strength, compressive strength, bending strength, water resistance stability, etc.
In the test, it is first necessary to determine the proportion scheme of the test sample, including the type of asphalt, the ratio of asphalt and aggregate,and the selection of additives.
Then, the test samples were prepared according to the designed ratio scheme.
Next, the test samples are tested for various performance indexes, such as compaction degree, shear strength, compressive strength, etc.
Finally, data analysis and performance evaluation are carried out according to the test results.
