Sažetak
TThis article examines the effective road reconstruction technologies applied during construction processes to ensure the required final quality of construction
work. The construction quality and especially the overall
levelness of roads are influenced by several factors. These
factors include high-quality implementation of road
structural layers, including active zones, which can be
adversely affected by the undisciplined application of
technology, insufficient engineering and poor geological
surveys. Suitable and effective reconstruction technology
provides the required quality of construction work yet does
not significantly extend construction time. The authors
propose stabilisation using cement or lime during reconstruction. This stabilisation method is used if the structure
of the bedrock layers is finely granular. The stabilisation
process consists of excavating the unacceptable bedrock
layer and mixing it with additives and water. A principally different bedrock stabilisation method consists of
completely replacing it with a gravel layer, which is used
when individual base layers are diverse and stabilisation
using additives would not guarantee the required results,
i.e. improved strength characteristics. In some cases, the
existing base layers are not suitable for use as road base
layers because of their characteristics, such as volumetric instability. For this reason, they must be replaced with
more suitable materials. This topic is documented by a
practical example.
