Description
Technical field
The present invention relates to a kind of novel road-making material, specifically, is a kind of waste tire rubber powder modified asphalt and preparation method thereof.
Background technology
Since the reform and opening-up, the communications and transportation cause of China has obtained great achievement highly visible.Country has proposed the great strategic task of development Modern Traffic transport trade---and put forth effort to advance resource-conserving, environmentally friendly communications and transportation development, implement " material economy and recycle special campaigns plan ", advocate the cyclic utilization of waste energetically.
As everyone knows, petroleum pitch has many good performances as a kind of mineral rubber ramming material, has become the main paver of construction fields such as highway, airport at present.But because the asphaltene molecule amount is less, wider distribution, so its mechanical property is big to the susceptibility of temperature, low temperature easily becomes fragile, and high temperature easily dissolves, and its elasticity, ageing-resistant performance and fatigue performance are also very poor.
Definition according to China's " asphalt highway construction technique normalizing " (JTG F40-2004), modifying asphalt is meant additives (properties-correcting agent) such as admixture rubber, resin, high molecular polymer, rock asphalt, levigated rubber powder or other materials, and the performance that makes pitch or asphalt is improved and the asphaltic binder made.
Rubber asphalt is that the rubber powder of content more than 15% (more than 180 ℃) under the condition of high temperature reacts the modifying asphalt agglutinate that obtains with molten the expanding of pitch.Rubber powder with asphalt high-temperature thorough mixing state under absorb molten the expanding of lightweight oil content face in the pitch, form the very high gel-film of asphalt content at the rubber powder particle surface simultaneously, the rubber powder particle links together by gel-film, forms a compatible body of solid-liquid that viscosity is very big.Adopt waste tire rubber powder, can improve bituminous crack resistance at low-temperature, high temperature stability performance, ageing resistance, anti-fatigue performance, elasticity, viscosity etc. effectively, strengthen the cling property of asphalt, and reduced the driving noise on road surface effectively, increased traveling security and comfortableness.
