Environment-friendly crack-resistant pavement base composition and preparation method thereof
The invention provides an environment-friendly crack-resistant pavement base composition which is prepared from the following raw materials in parts by weight: macadam, carbide slag, fly ash, phosphogypsum and water. The composition can also comprise Xinjiang coal slag of which the particle size is 60-80 meshes. The preparation method of the base comprises the following steps: mixing macadam with the particle size of 0.1-5mm, macadam with the particle size of 5-10mm and macadam with the particle size of 10-30mm, adding water, mixing to prepare a graded macadam mixture, and carrying out sealed curing for 10-15 hours; mixing with the carbide slag, fly ash, phosphogypsum and selectively Xinjiang coal slag to obtain an industrial waste residue mixture; and mixing the industrial waste residue mixture and graded macadam mixture with a dust mixer while adding water, thereby obtaining the environment-friendly crack-resistant pavement base. The pavement base can slightly expand instead of shrinking, so that the stable macadam base has favorable water stability and compactness.
