An asphalt pavement modification system and method for improving aging resistance of asphalt pavement and a method of manufacturing reclaimed asphalt pavement. The asphalt pavement modification system and method include using one or more antioxidants and one or more recycling agents in a blended binder to provide improved short term and long term performance of the asphalt pavement. The method of manufacturing reclaimed asphalt pavement includes mixing at least one antioxidant with at least one recycling agent to form a binder that constitutes a portion of the reclaimed asphalt pavement. One of the antioxidants may be zinc diethyldithiocarbamate.

A manufacturing method of a plugged honeycomb structure including a plugging material preparing step of mixing a ceramic raw material, a pore former, a thickener, an organic binder, a dispersing agent, and water and preparing the plugging material which is slurried, to form the plugging portions, wherein the plugging material preparing step includes: a powder mixing step of mixing the ceramic raw material, the pore former, the organic binder and the dispersing agent each of which is constituted of powder, at predetermined blend ratios, a thickener mixing step of adding and mixing the thickener to a powder mixture obtained by the powder mixing step, and a kneading step of adding the water to a thickener added mixture obtained by the thickener mixing step, to perform kneading.

The present disclosure relates to a high-strength concrete and a preparation method thereof. The high-strength concrete includes lignin, recycled fine powder, cement, water, sand, gravels and a water reducing agent. The recycled fine powder is recycled fine powder of discarded concrete, and is prepared by separating solid waste of discarded buildings, then performing impurity removal and crushing processing, and grinding same by a ball mill into dust with a particle size of less than 0.16 mm. The lignin is discarded wood lignin, which is prepared by crushing the wood, stirring and extracting a sodium hydroxide aqueous solution with a mass concentration of 5% for 1 to 2 hours at the temperature of 80 DEG C. to obtain a black lignin alkali solution, adding a hydrochloric acid solution with a mass concentration of 30% into the alkali solution for stirring, and making the pH reduced to 7.0 for standing and layering.

The present invention relates to a process for producing a pore-containing granulate, comprising the following steps: a) producing a foamed mass using sand, hydraulic binder, foaming agent and water, b) pouring the foamed mass into a filling mould, c) partially curing the mass over a first period of time at ambient pressure to form a green block having a first target strength, and d) demoulding the green block, the process comprising the further steps e) splitting the green block into at least two sub-blocks, l) further curing the sub-blocks over a second period of time at ambient pressure until a second target strength is reached and g) breaking the sub-blocks to form pore-containing granulate with a desired particle size distribution. Furthermore, the present invention relates to a process for the production of a pore-containing artificial stone which contains the granulate as an additive.
