Then the text constructs behaviour simulation and uses the ameliorated AHP and fuzzy comprehensive evaluation to evaluate the construction process according to the fuzzy system, which concludes the grade of control of pavement construction.
So a new pavement construction is put forward against normal asphalt concrete pavement,whose construction has following character: the surface layer of asphalt pavement uses big peecenbagee of void asphalt concrete(the peecenbagee of void ranges from 15%~25%), the thickness is about 4~5 centimeter,the middle layer uses compact gradation asphalt concrete, upon which tack coat is laid out for better combination between layers and better prevention from leaking downward of rain.
According to the cement concrete pavement construction situation, the quality disease is analyzed, the crack of road surface, material, gradation, water cement ratio, construction noise and the influences on quality are analyzed, and the reasons which creat the appearance quality are expounded.
This paper expounds the general principles of the economic analysis of the pavement construction, introduces the cost composition and calculation mo del in the life cycle of the pavement, and puts forward the pavement's economic evaluation method through the actual example.
Eight different asphalt binders representing a wide range of applications for pavement construction were tested in uniaxial tension, bending, and shear stresses.
Properties of Ironstone Lateritic Gravels in Relation to Gravel Road Pavement Construction
This method is most promising for road and airport pavement construction in tropical regions where fine textured lateritic soils (red clays and silts) occur over large areas.
The problem of achieving reproducible laboratory test data under field conditions is perhaps the most challenging aspect of utilizing local gravels for pavement construction in tropical and sub-tropical conditions.
Experiences in road construction in the tropics within the past 50 years or so have established that local materials specifications and pavement construction technologies have to be developed in relation to the climatic conditions.
