Abstract:

In order to evaluate the flexural-tensile property of cement stabilized coal gangue roadbase materials, flexural-tensile strength and flexural-tensile modulus of materials, whose cement dosage range from 4% to 7%, were tested on the automatic servo universal material testing machine with one-third loading method. Based on the test data, correlation equations between cement dosage and flexural-tensile strength and flexural-tensile modulus were established. Results show that: cement dosage is an important influence factor of flexural-tensile property, both flexural-tensile strength and flexural-tensile modulus increase linearly with the increase of the cement dosage. Cement stabilized coal gangue roadbase materials have a good flexural-tensile property and suitable for base in the pavement structure.
