Pile driving machine for road infrastructure

In today’s world, everything is moving faster and faster, that’s why the WALDEVAR team is determined to be one of the main drivers of infrastructure development and improving the safety of roads and highways in Romania and beyond.

In the activity of road infrastructure development, you need equipment that uses the latest technologies to achieve operational efficiency.

Our company supplies professionals WALDEVAR HWL 400R semi-mobile crawler machine. This is a machine for inserting piles into the ground and can be used to fix the railings on the side of the road.

Thus, road safety will be significantly improved on the road with long-term benefits in road operation.

The HWL 400R pile driver can be used for digging holes in the ground and drilling piles in the ground. Thus, regardless of the complexity of the infrastructure work, WALDEVAR equipment will offer a constant performance at a competitive price.

WALDEVAR’s priorities include compliance with the performance and quality indicators established by the regulation of the public and private domain administration service, but also the application of efficient management methods, leading to a reduction in operating costs. Last but not least, the organization, planning and monitoring of the execution of the works in a systematic and timely manner to ensure the development of road traffic in conditions of safety and comfort, while preserving the road heritage.

Passive safety systems for road infrastructure

Passive road safety equipment is positioned in locations that have serious consequences in the event of a vehicle leaving the roadway uncontrollably. These are items that can be hit by a vehicle. However, the equipment is built and tested to ensure that the impact of the vehicle with such a structure is less severe compared to the dangerous roadside elements.

The need to install safety equipment arises when the safety of the area cannot be improved by other methods. Some off-road hazards may be removed, or the risk may be reduced by government intervention. However, in many situations the danger cannot be removed and it is more economical to install safety elements such as railings.

Road builders can install railings on the edges of the roadway or on the central axis separating the road. Their goal is to block a vehicle out of control to leave the road. The parapet is created only to manage the oblique impact.

The railing systems can be installed longitudinal and median. Depending on their use, the parapets can be temporary or permanent. The two types differ in the anchorage variant with the road surface and the degree of impact protection.

Safe and efficient road infrastructure at European level

The European Union has a strategy for land transport that promotes efficient, safe and environmentally friendly mobility.

Therefore, the objectives of European road transport policy aim to promote freight and passenger services, in a fair framework from a competition perspective. EU objectives also include the promotion of environmentally friendly technical standards that ensure fiscal and social harmonization at European level, as well as ensuring that road transport rules are complied with efficiently and without discrimination.

Existing legislation applicable to road transport services lays down common rules on access to the profession and the market, working time standards, together with common rules on barrier charges for heavy transport vehicles. The European Commission is also promoting the increase in the number of safe car parks along the trans-European road network.

Diminishing the impact of road infrastructure projects on the environment

The main impact on the environment comes from the daily traffic (fuel consumption of cars and trucks) during the road use phase.

The road resistance associated with the asphalt texture has the highest potential impact because it is directly correlated with the level of fuel consumption of the car. A 10% reduction in rolling resistance could lead to 1-2% improvements in fuel consumption, according to a study cited by the EU.

Traffic congestion could be caused by factors outside the scope of public works (rush hour traffic, accidents, car breakdowns, difficult weather conditions) or caused by direct works such as lane closures, roads construction activities or road infrastructure repairs. The fuel consumption of cars can be influenced by both queues and implicit traffic at low speeds, in the construction or maintenance phase of roads.

The stage of the road infrastructure cycle with the second greatest environmental impact is the construction phase, in which the hotspots are related to the resources used and the emissions and impact of the ecosystem associated with the production of materials, including extraction and transport.

The use of resources is influenced by the amount of waste generated during the product manufacturing process, on-site construction and maintenance processes, which can be significant as a proportion of the general material flows on a construction site.

This highlights the importance of design and specification for resource efficiency. The most significant road infrastructure elements to be addressed are earthworks and ground works, base and sub-base, along with operations to stabilize concrete slabs. In this sense, the recycling and reuse of construction materials can help reduce the impact on the environment and the development of a circular economy.

A related consideration in the case of construction materials with high volume and weight is related to the transport of aggregates (natural, recycled or secondary) to production sites. The transport of these materials is usually done by truck, which results in carbon emissions, which are generally higher or equal to those for the production of these materials. If these materials are traveled more than 25 km, the resulting emissions can significantly contribute to the environmental impact in the production phase for the main road elements. Minimizing transport-related emissions can help promote the use of lower-impact modes of transport, such as rail or sea, for the transport of these materials.

Finally, the use of recycled materials, such as aggregates from construction and demolition waste, can contribute to the development of a market for such materials, in line with the EU’s circular economy objectives, and can provide benefits associated with resource efficiency.
