Abstract
The invention relates to an asphalt thin-layer surface mixed material which is mainly prepared from the following raw materials in parts by weight: 100 parts of basalt stone, 4-10 parts of pressure-sensitive modified asphalt, 2-6 parts of cement, 2-6 parts of water and 1-3 parts of an additive. An asphalt thin-layer surface can be made from the raw materials and can be paved in a cold stirring cold paving mode, and the thickness is greater than conventional construction thickness, so that harm such as water seepage and densification track can be effectively avoided.
Description
(1) technical field
The present invention relates to the technology of paving the way, be specifically related to a kind of pitch thin overlay mixing material.
(2) background technology
Ultra-thin asphalt wearing course technology, is mainly used in the preventive maintenance of high-grade pitch or cement pavement and the corrective maintenance of slight disease.Utilize tampered paver in construction process, just can synchronously complete modified emulsifying asphalt spray and hot asphalt mixture pave.Rolling again through Steel Roller, early disease road surface just can take on an entirely new look.By calculating in theory, general express highway pavement work-ing life is at least more than 6 years, but excellent Ultra-thin asphalt wearing course is 8-10 work-ing life.Meanwhile, wearing course surface irregularity can increase the sliding resistance of wheel; Noise reduction, water permeability good, can greatly reduce rainy day common water smoke, improves visibility meter.Although wearing course only have two centimeters thick, can combine closely, pass disease with original road surface, this has larger practical value to energy-saving and cost-reducing.Pitch thin overlay generally selects heat construction, easily causes later stage compactness inadequate, thus produces the problems such as infiltration, densification type rut.
