Method of constructing highways using two or more layers of bituminous coatings spread onto a foundation is claimed in which the layer is contact with the foundation is an aggregate coated with 4-5.2 (4-4.4)% of its own wt. of bitumen to a thickness of 10-14 cms. The aggregate is pref...
In order to detect interface flaws between bituminous and hydraulic layers of composite pavements, three-dimensional finite element simulations of the deflection under a standard axle load were carried out. The pavement layers are considered as linear elastic and the interface behaviour follows three ...
The rutting of bituminous pavements is the phenomenon most encountered on roadways of desert regions, where the temperature is too high and which will cause a decrease in the stiffness modulus of asphalt mixture. In this experimental work, the results of resistance to the rutting phenomenon obtained...
Brazil’s large territorial extension and the predominance of transportation mode in it have been demanding from Road Engineering suistainable ways of building infrastructure. Deficit of materials in certain regions of the country, high cost of associated transport and a need to reuse waste are pushi...
This paper presents the results of the first phase of a research project dealing with the constitutive description of the behaviour of well-graded granular materials when used for base or subbase layers in flexible pavement structures (so-called “unbound granular materials”, UGMs). Monotonic and...
9. A composite lattice assembly for reinforcing bituminous layers comprising: a fleece member; a first set of lattice threads arranged on the fleece member; a second set of lattice threads are least partially crossing over the first set; and a plurality of Raschal threads securing the lattice ...
1) inspection of depth of road layers 结构层厚度检测2) structural course thickness 结构层厚度 1. By analyzing the relationship between the maximum size,structural course thickness and the mix- ture performance of bituminous mixture,this article tested the porosities and performance of several kinds...
On the basis of the Kai Yang Expressway construction practice, the application of single hot bituminous surface treatment with premixed macadam to the lower seal coat is discussed and a foundation for the further study of bituminous seal coat design and construction given. 通过开阳高速公路下封层的...
Bituminous road surfacing - using higher bitumen proportions and less thickness of layersMethod of constructing highways using two or more layers of bituminous coatings spread onto a foundation is claimed in which the layer is contact with the foundation is an aggregate coated with 4-5.2 (4-4.4)...
Equipment for reconstruction of bituminous road surface layers involves one or more microwave transmitters installed in apparatus for movement over layers in order to radiate themWith a slow advance speed, the equipment with the aid of one or more microwave transmitters (1) the road surface layers ...
