Thin layer overlaying surface construction method suitable for pavement overhaul and intermediate maintenance and preventive conservation
The present invention provides a thin layer overlaying surface construction method suitable for pavement overhaul and intermediate maintenance and preventive conservation, a synchronous construction process meeting the thin layer overlaying surface technology can be formulated by adjusting and upgrading on the basis of the traditional ultra-thin wearing layer construction process according to the characteristic of a thin layer overlaying surface, especially an extremely-thin wearing layer with the thickness of 0.8 to 1.5cm, the thin layer overlaying surface construction method mainly includes preparation before construction, original pavement disease damage treatment, fine milling napping processing, milling process knife head cooling water spray control, pavement cleaning, mixture mixing, mixture transportation, mixture paving, mixture rolling compaction, detection after forming and opening to traffic, the construction process conditions are clever and flexible to control, by the process using a fine milling machine for processing an old subgrade surface and emulsified asphalt and mixture synchronous paving, construction of the thin layer overlaying surface especially the extremely-thin wearing layer can be effectively realized, the major technical indicators of the constructed extremely-thin wearing layer are equivalent to that of an ultra-thin layer with the thickness of 20mm abroad, the cost is reduced by 25%, and a contribution is made for popularization and application.
