Document Type and Number:
WIPO Patent Application WO/2011/027926
Kind Code:
A1
Abstract:
Provided is a temperature-adjusted and modified recycled ASCON composition for reusing 100% of waste ASCON for road pavement, and a method for manufacturing same, wherein the composition is used in asphalt pavement as a material for the wearing course, surface course, binder course, and base course, and the method comprises: feeding 100 wt % of waste ASCON aggregate having up to a 53 mm particle size distribution into a mixer via a feeding inlet for new aggregate; adding 0.1 to 20 wt % of a recycling modifier and 0.1 to 20 wt % of a temperature-adjusting additive to the waste ASCON via the feeding via the inlet for new aggregate; and homogeneously mixing said materials at 5 to 180°C for 0.5 to 3 minutes. The recycling modifier improves the physical properties of recycled ASCON, while the temperature-adjusting additive adjusts the temperatures for producing and constructing recycled ASCON. The present invention may provide economic, social and technological conveniences by improving the overall recycling technology of waste ASCON. The conveniences may be achieved by virtue of: cost-saving in production by using only waste ASCON without any new materials; saving waste disposal costs; preventing the destruction of nature to obtain aggregate; reducing the consumption of new asphalt; preventing environmental pollution through the reuse of waste products; preventing the early occurrence of plastic deformation and fatigue cracks due to improving the quality of the recycling modifier; economic benefits from the prolonged lifespan of road pavement; the possibility of being used as a material for the wearing course and surface course of major roadways; saving energy in the production and construction of recycled ASCON by adding the temperature-adjusting additive; and reducing greenhouse gas emissions.
