4. the job practices of claim 1 road surface low-noise micro-surfacing functional layer is characterized in that it is made up of following step:
(1) cleaning road surface
Earth, weeds, greasy dirt and other foreign material on the cleaning road surface;
(2) laying-down
Direction marks control line along paving;
(3) cover that paves
Little table place paver vehicle is opened to the construction starting point, aim at control line, put down the case that paves, the adjustment case that paves makes its periphery be adjacent to former road surface, by the weight proportion of setting will gather materials, the cation-modified mulseal of SBR, rubber powder, filler, water and additive inject in the case that paves, and stir into the emulsion mortar of flow regime, the emulsion mortar is paved on the road surface with little table place paver vehicle;
(4) roll
When compound just adopts 10 tons rubber-tyred roller water spray to roll 1-2 time during one-step forming, thickness is 8～10mm;
(5) initial curing
1. forbid all vehicles and pedestrians;
2. at the seal of crossing intersection part, carry out the stucco protection;
3. when the cohesion of antiskid wearing layer during greater than 2.0NM, open to traffic;
4. on-the-spot cleaning;
(6) quality inspection
Except that " the highway subgrade road surface on-the-spot test rules " JTJ059-95 by Ministry of Communications's issue detects, also the fc-specific test FC vehicle is passed through test segment, pass-by noise in its car is detected, transfer after the assay was approved and use.
