This case analyzed the energy consumption and carbon emissions of highways cement pavement structure and
asphalt pavement structure during their life cycle under the same traffic volume and weather conditions and demonstrated the reliability of the calculation results.
With the rapid development of modern transportation in the world, the
asphalt pavement structure has become one of the most preferred structures of highways due to its advantages for comfortable driving and fast traffic opening [1].
Fatigue is one of most important distresses in
asphalt pavement structure due to repeated load of heavy traffic services which occur at intermediate and low temperatures as shown in Figure 11.
An
asphalt pavement structure consists of three layers.
And, the continuously reinforced concrete and asphalt composite pavement (CRC+AC) is featured by high integral structure strength, superior driving comfort, long service life, and low maintenance cost, which is deemed as the development direction of the long-life
asphalt pavement structure of the heavy-load transportation expressway [1-3].
Density requirements in Kansas vary based on location within the
asphalt pavement structure and the expected axle loadings.
Modeling of
Asphalt Pavement Structure with Geosynthetics Interlayer Using of Finite Element Method, in Proc.
Using full-scale performance and laboratory tests, the researchers demonstrated that asphalt modified with crumb rubber could significantly slow or stop the growth of fatigue cracks in a composite
asphalt pavement structure. A hybrid technique to modify asphalt with a combination of crumb rubber and conventional polymers, called terminally blended crumb rubber, exhibited good fatigue cracking resistance relative to the control binder.
Having analysed the volume and composition of heavy traffic of the test section in 710 m length and 27 different experimental pavement structures, it was determined that the largest destructive impact on
asphalt pavement structure is caused by a two-axle truck tractor with three-axle semitrailer and heavy-weight vehicles with three axles and four axles.
