Asphalt paving adopts a whole set of Work machine, comprises bitumen feed machine, slope spreading machine tractor, slope spreading machine, incline configuration formula road roller, inclined-plane rubber tyred roller, inclined-plane road roller tractor, mobile operation car, sprinkling truck, excavator, loader, in runway both sides standing tree template before paving, template thickness is than paving thickness on average low 5mm, the guide rail of long 30m is placed in the both sides, terminus position row track that pave, ensure the stability of terminus position slope spreading machine, circuit hardened verge is placed bitumen feed machine, and tractor is placed on road to Ti Ding, bitumen feed machine, tractor and slope spreading machine are equipped with sychronisation, make bitumen feed machine, the moving ahead with slope spreading machine on circuit that move ahead of tractor keeps synchronous, and use incline configuration formula road roller and tractor totally two groups of machineries carry out rolling operation, and construction point top and the bottom, track are rolled, before the bituminous mixture that paves, and reply cutting optimal, transverse joint interface, the side contacted with new black top compound, adopts hand fit's pitch sprinkling car to spray one deck sticking layer oil, inclination angle is greater than to the chamfered portion of 35 °, uses twice painting of high viscosity special sticking layer oil employment work point to spill.
For the curved surface that makes to pave has overall ride comfort, the every runway of high loop surface must pave continuously.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention can adapt to the camber asphalt paving that curvature constantly changes, and can reach again overall ride comfort effect, solves domestic camber asphalt paving blank.
2, slope spreading machine has adjustable every block screed feature, controls to pave any line style cross section by computer.
3, the principle of the invention is simple, feasibility is strong, practical, precision high (± 2mm), can meet skid pad high speed circuit and other high-precision curved asphalt paving construction requirements.

Detailed description of the invention
See accompanying drawing, skid pad high speed circuit curved surface pitch rolling method, before high speed circuit bituminous pavement paving on runway shuttering, ensure the uniformity of the overall coefficient of loose laying of paving concrete pavement, and pave by width of roadway divided lane, for ensureing that runway overall coherence is without transverse joint when paving, incline configuration formula machinery is adopted to roll along direction of traffic.Every layer of construction longitudinal seam staggers, and do not affect overall ride comfort, and facing joint position is on marker line, and presses driveway partition, the concrete step that rolls is:
For the circuit that cross section is cubic parabola curved surface, asphalt paving adopts a whole set of Work machine, comprise bitumen feed machine (10), slope spreading machine tractor (12), slope spreading machine (11) (curved surface scraper plate) (7), incline configuration formula road roller (19, 20), inclined-plane rubber tyred roller (21, 22), inclined-plane road roller tractor (15, 16, 17, 18), Mobile lifting car (23), excavator (13), Small-scale Flat rams (14), loader (24), 5t vibratory roller (25), sprinkling truck (26).
Every day is changed the data that pave before construction, regulates scraper plate controller (9), utilize scraper plate controller (9) to make curved surface scraper plate (1) be adjusted to the desired line style of curved surface by Data Control case (8).In runway both sides standing tree template before paving, template thickness is than paving thickness on average low 5mm, and paving, 30m guide rail is placed in both sides, terminus position row track, ensures the stability of terminus position slope spreading machine.At circuit hardened verge (6) upper placement bitumen feed machine (10), carry top road (1) upper placement slope spreading machine tractor (12), bitumen feed machine (10), slope spreading machine tractor (12) and slope spreading machine (11) are equipped with sychronisation, make bitumen feed machine (10, moving ahead of slope spreading machine tractor (12) keep synchronous with slope spreading machine (11) moving ahead on circuit.For the curved surface that makes to pave has overall ride comfort, the every runway of high loop surface must pave continuously.Use incline configuration formula road roller (19,20) and inclined-plane rubber tyred roller (21,22) totally two groups of machineries carry out rolling operation, and construction point top and the bottom, track are rolled.Intact for guaranteeing upper and lower surface layer bonding, before the bituminous mixture that paves, reply cutting optimal, transverse joint interface, the side contacted with new black top compound, adopt hand fit's pitch sprinkling car to spray one deck sticking layer oil.Inclination angle is greater than to the chamfered portion of 35 °, uses twice painting of high viscosity special sticking layer oil employment work point to spill.For making transverse joint along connecing, 5t vibratory roller (25) is adopted to roll seaming position in the start, end that pave.
