Description
Technical field
The invention belongs to the Materials Science and Engineering field, be specifically related to a kind of paving structure of road surface.
Background technology
Along with development and national economy, the high-grade highway construction of China, particularly expressway construction is advanced by leaps and bounds.Owing to the climatic environment of complexity and abominable reasons such as transportation condition, many high-grade highways come into operation soon, early stage damage has in various degree just appearred, main diseases such as the bad and cracking of rut, damage by water occur as asphalt concrete pavement, disconnected plate appears in cement concrete pavement, ftracture, come to nothing and damage such as purt mud.Keep in repair though dropped into substantial contribution every year, often mend very and mend, not only the later period maintenance investment is big, and has influenced the traffic capacity of traffic and the comfortableness of driving, causes harmful effect socially.In addition, along with the quickening of Urbanization in China and the raising of people's living standard, the function of use of road pavement has also proposed very high requirement, such as the safety of travelling, comfortableness and environment friendly etc.How can provide a kind of technical ability to satisfy pavement performance and endurance quality, the novel road surface structure that can satisfy function of use has again become present research focus.
Asphalt concrete material and cement concrete material are two kinds of main ground surface materials of high-grade highway, and these two kinds of typical ground surface materials have been widely used in the road structure of urban road and high-grade highway.But,, cause the intensity of asphalt pavement structural layer and rheological characteristic to be acted upon by temperature changes very big because bituminous material is the very strong material of a kind of response to temperature.During summer high temperature, the reduction of bituminous material viscosity causes that cohesive force weakens between aggregate particle, if under horizontal force action, very easily make to produce between the bituminous mixture particle and slide and displacement, the shear deformation breaks down that causes asphalt pavement structural layer to form wave, gather around bag and so on has reduced the comfortableness of driving a vehicle.On the high-grade highway of canalized traffic, asphalt concrete pavement is easy to generate excessive plastic strain and forms rut.In the winter time during low temperature, though the intensity of asphalt concrete pavement structural meterials increases to some extent, because of the raising non-deformability of bituminous material viscosity greatly reduces, show fragility, the result causes the asphalt pavement structural layer cracking.Characteristics such as Concrete Pavement Materials has that non-deformability is strong, long service life and routine servicing expense are low produce deficiencies such as repairing difficulty after the disease but this road structure has driving comfort difference and road structure.
In recent years, domestic cement mortar grouting formula semi-rigid pavement is studied, and carried out the laying of test section.The good characteristic separately of these two kinds of typical ground surface materials is given full play on this kind road surface simultaneously, can solve the rut, damage by water of asphalt concrete pavement bad and cracking and cement concrete pavement disconnected plate, ftracture, come to nothing and disease such as purt mud.But because this kind road surface all is laid on the wearing layer on road surface, exist following problem at present: 1) half of the preparation flexible general modulus of resilience is bigger, causes the road surface rigidity to increase, and the road surface is easy to crack; 2) rigidity on road surface increases, and planeness descends, and has influenced the comfortableness of driving; 3) aesthetic property on road surface is subjected to very big influence.
Therefore, invent a kind of half-flexible pavement material with suitable mechanical property, and with this half-flexible pavement material as deck, the combined type road paving structure that exploitation has draining, noise reduction, function wearing layer such as anti-skidding has important practical significance.
