Application of Basalt Fiber Chip Sealing Technology in Preventive Road Maintenance
Aiming at ensuring the quality of preventive road maintenance construction,the application of Basalt Fi-ber Chip Sealing technology in preventive road maintenance is studied by taking a certain grade 1 highway as an ex-ample.The construction technology uses modified asphalt and basalt fiber as the main materials,and determines the reasonable mix ratio and the construction process of basalt fiber chip sealing layer,and completes the pavement con-struction in strict accordance with the construction standards and construction parameters.The test results show that the depths are all above 0.55 mm,the minimum friction coefficient is 70.6,and the maximum is 75,which meet the construction standard.
