Specifically, the effect of (a) type and replacement ratio of reclaimed aggregate, (b) chloride boundary conditions, (c) initial aggregate chloride concentration, and (d) thickness of contaminated aggregate shells on time to corrosion cracking was investigated herein.
The results showed that geocell reinforces the unbound aggregate thus reducing the deformation along with the reduction in the required thickness of the aggregate layer of unpaved roads.
It is evident from the studies that geogrids contributed to improved performance as well as reduction in thickness of the aggregate layer.
Finally, the benefits of geosynthetic reinforcement was quantified, within the context of the AASHTOWare Pavement ME Design guide, in terms of increasing the resilient modulus of base course layer and/or reducing the thickness of base aggregate layer in pavement structure.
This paper investigates the influence of particle shape on overestimation of ITZ thickness for aggregate shapes which have the same sphericity values as Platonic particles; specifically, spheroids of differing geometries.
Two new concepts, surplus thick-ness of sand and thickness of paste around aggregate, were introduced in the processes of sand filling gravel void and paste filling aggregate void respectively.
And the influence factors of base layer on pavement performances include the resilient modulus, material type, thickness of base, gradation of aggregate, moisture content, and the property of subbase layer, which are divided into internal and external causes.
For micrometastasis and ITCs analysis, we examined three serial sections, each 10 μm thick (with an aggregate thickness of 30 μm), from each of the paraffin blocks of the lymph nodes, which were used for CAM5.2 immunohistochemical examination as described below.
In addition, the model predicts that the chloride diffusivity of concrete composite materials depends on the chloride diffusion coefficient of the matrix and ITZ, volume fraction of the aggregate and ITZ, with the volume fraction of the ITZ influenced by aggregate size distribution, the volume fraction of aggregate and thickness of the ITZ.
The effects of the mesostructural parameters (i.e., the shape, gradation and volume fraction of aggregates and the thickness and permeability of ITZ) on the permeability of concrete are comprehensively investigated.
