Existence of strongly proper dyadic subbases [PDF]
Logical Methods in Computer Science, 2017 We consider a topological space with its subbase which induces a coding for each point. Every second-countable Hausdorff space has a subbase that is the union of countably many pairs of disjoint open subsets.

The usage of marginal aggregate as subbase layer
Jurnal Ilmiah SINERGI, 2023 Aggregate holds the main role in determining the quality of pavement layers. Unfortunately, the locally available aggregates sometimes did not pass one or more requirements stated in the standard, making these aggregates technically unable to be used ...

SUBBASE STABILIZATION WITH FLY ASH
Facta Universitatis. Series: Architecture and Civil EngineeringDue to increased activities in civil engineering, and especially in the transport infrastructure, and thus an increase in the use of additional construction materials, innovative solutions are needed in finding alternative materials for the preservation ...

Effect of Soaking on the CBR-Value of Subbase Soil [PDF]
Engineering and Technology Journal, 2011 The effect of soaking on the top and bottom CBR value of a sub-base is studied in this paper. Fourteen CBR samples were prepared at 95% relative modified AASHTO compaction .Two CBR samples were prepared for each soaking period of 0,4,7,14,30 and 60 days.
