“…Nowadays, as mentioned in the study of Matuszkova and coll., it is crucial to reduce the costs of transport, given that exceeding the maximum permitted masses of vehicles/vehicle combinations can lead to the excessive damaging of the road network. Other factors to consider include the risk of exceeding the maximum permitted masses, which can increase the risk of a technical problem in the vehicle or a hazardous change in its driving performance [23].…”

Global Assessment of Bridge Passage in Relation to Oversized and Excessive Transport: Case Study Intended for Slovakia

The development of an economy and, in particular, the construction of new infrastructure as well as industrial enterprises creates demand for the road transport of oversized freight that exceeds the maximum permissible total mass of vehicle combinations with its share on the axles. Failure to comply with the defined technological processes and a deficiency in the assessment of permitting such forms of transportation can have a large adverse effect, predominantly on the lifetime of bridges in a road network, which can have international implications as well. There is no legislation adopted by the EU Member States, which would at least partially unify the authorisation procedures of these forms of transportation and, therefore, it results in problems when crossing borders and leads to differences related to the assessment of bridge passages. If there is no systematic inspection of this kind of transportation, it can lead to permanent damage of these bridges as well. Currently, and not only in Slovakia but also in other states, the assessment of bridge passage for certain routes is used for heavy and oversized transportation. It means that if we use 100 transports, 100 assessments of individual routes are needed, although some are the same routes or the same vehicles/vehicle combinations used for a number of transports. Thus, the authors designed a global assessment for bridge passage in relation to heavy and oversized road transport while verifying it in the conditions of the EU Member State from Central Europe–Slovakia. Roads are full of different types of vehicles/vehicle combinations for which the axle loads and distances of the axles (wheelbases) are important. Thus, there were vehicle/vehicle combinations parameters (big data) observed, for which the routes relating to heavy and/or oversized transportation were assessed from 1 January 2016 to 31 December 2020 in Slovakia. The global assessment of bridge passage introduces an entirely new approach within the procedure for obtaining a special permission for road use as well as within transport use itself. Given the low presence of freight with an abnormal axle load or enormous total mass, it is appropriate to define the limited conditions under which it would be possible to implement the global assessment in practice as well.

Subdrain layer is a type of pavement that can reduce excess water from rainwater so that it can seep into the ground. The purpose of this research is to find the relationship between the optimal water velocity to pass through the base layer and maximum carrying capacity. Sieve analysis was carried out to obtain aggregate gradation variations by modifying the Bina Marga Standards 2010. There are 5 different types of gradations used based on the reduction in the percentage of filler specifications of 8%, 5%, 4%, 3%, and 0%. Calculation of fillers is used to find out the weight of aggregate each sieve size. In addition, the compaction test was carried out on ASTM D Modified 1883 - 87 to obtain optimum water content by using from the maximum dry density curve. The results of compaction the maximum dry density varies with the range 1,911-1,981 gr/cm3. The results of the maximum dry density show that the optimum water content varies between 9-10%. Next, the test sample is reused for CBR testing which aims to determine the carrying capacity of the test sample. Results tend to decrease when the filler is reduced. Obtained CBR test results is in the range of 62-74%. The sample is reused for the infiltration test to find the speed of the water capable of passing the test sample. Based on the results of the infiltration test, the constant infiltration rate varies from 3.143 to 6.750 mm/minute. The constant speed tends to increase when the percentage of filler decreases.
