Abstract

The invention provides porous ceramsite and asphalt concrete. The porous ceramsite and asphalt concrete is prepared from components in percentage by mass as follows: 45%-55% of nano-TiO2 sintering-free porous ceramsite, 4.5%-5.5% of SBS modified asphalt and 39.5%-50.5% of supplementing mineral aggregate. The porous ceramsite and asphalt concrete can be applied to laying of automobile exhaust degradation type ultra-thin wearing courses of pavements and has economic benefit, environmental protection benefit and social benefit.

Description

(1) Technical field [0001] The invention belongs to the technical field of road surface materials in road engineering, and in particular relates to a porous ceramsite asphalt concrete and its application in laying an ultra-thin wearing layer degraded by automobile exhaust. (2) Background technology [0002] With the sharp increase in the number of cars in our country, a large amount of exhaust gas emitted by cars has seriously polluted the atmospheric environment, greatly increasing the frequency of "smog" weather. [0003] At present, in addition to the introduction of various exhaust emission control administrative regulations and oil product improvement measures, researchers have also proposed various exhaust gas-degradable new pavement materials and new technologies, including exhaust-degradable asphalt, asphalt mixture, cement, etc. Mortars, coatings and coils, etc. The tail gas degradation efficiency and scope of application of these new materials and new technologies...
