2020 - English
For the last several years, the attention has been devoted to the development of ecofriendly construction materials with the aim to reduce the environmental impact of construction. The integral part of this development is to find applications for which the recycled materials could be used efficiently. The presented study deals with the development of recycled aggregate fibre reinforced concrete which is going to be used for an innovative precast concrete pavement system. The system is being developed recently at Czech Technical University in Prague with the aim to provide a system for airfield pavement with rapid construction and recycled material utilization. The investigated material is going to be used for construction of a sub-base course which is underneath a surface course of precast concrete elements. Within the scope of the work,standard laboratory tests were conducted with the aim to observe mechanical properties of recycled aggregate fibre reinforced concrete. The obtained findings showed that the material exhibits ductile behaviour likely due to very long polypropylene fibres used for strengthening concrete matrix. On the contrary, the tested material has low modulus of elasticity in comparison with conventional concrete. Subsequently, the pilot construction of the sub-base course was carried out in order to examine both concrete mixture preparation and concrete course installation in practice. The obtained findings showed that a compaction ratio of the material is about 20%. Moreover, a flat surface of the sub-base course was hard to achieve considering the used manufacturing technology. Keywords: pervious concret; fiber reinforced concrete; airfiled pavement; recycled aggregate; flexural strength Available in digital repository of ČVUT.

Frontier Detection in Consecutive Grid Maps with Set Reduction
2020 -
The paper deals with the problem of frontier detection. The main contribution of the paper is an approach for reducing a set of detected frontiers. All maps in the paper are assumed to be 2D occupancy grid maps. The detection algorithm is based on computing fused map from the maps obtained in the last two-time steps. Frontiers are detected in the fused map instead of the current map. Moreover, the set of detected frontiers is then reduced by applying two restriction rules. The proposed algorithm is verified in the experiment performed in the simulation environment. The results are compared with a basic naive detection approach and with an approach which does not apply the reducing step. Available in the ZČU Library.
