Understanding the Importance of Bridge Expansion Joints and Tactile Indicators

In the past, streets were mainly constructed to transport goods and services, neglecting the aspect of human accessibility. As a result, cities overlook the fact that every individual is a pedestrian at some point in their daily routine and that roadways serve as the primary means of transportation. Therefore, we must place importance on roadwork. However, it should be noted that the construction of roads can be dangerous, with workers risking their lives every year. Without proper caution, these workers are vulnerable to severe accidents.

The selection of safer vehicles, the implementation of standardised checklists and procedures, and education of employees are essential measures to ensure optimal safety and efficiency.

Therefore, it is our responsibility to uphold a level of excellence in our efforts to protect the citizens of Australia. However, we must also recognise that there is still work to be done in collaboration with contractors, government officials, and the community to ensure the safety and well-being of all individuals on our roads.

Today, in this blog post, we will learn about two different road safety systems that are a must for the roads in Australia.

Bridge Expansion Joints

Nowadays, bridges face a lot of strain and pressure. This is why expansion joints are utilised to withstand this mechanical stress. They are primarily employed in the bridge construction process. It is also an element that ensures the longevity of the bridge. The expansion joints on the bridge effectively aid in the movement and rotation of the superstructure. Only a tiny portion of the intricate construction is visible when properly installed.

The reason why bridge expansion joints must be installed correctly and safely is because of the following reasons:

• It provides safety that keeps the bridge in place.

• Assist in safeguarding the concrete structures beneath the joints.

• Utilising a high-quality bridge expansion can result in cost savings.

• Aids in reducing heat cycle contraction and expansion.

• Shields the concrete buildings from harm caused by traffic in cars.

• It helps prevent concrete slippage and natural shrinkage.

Types of expansion joints:

The two significant types of bridge expansion joints that are necessary for the construction and maintenance of bridges are:

• Open joints: These bridge expansion joints enable unrestricted water and debris passage. They are a poor option since they cause debris accumulation. 

• Close joints: These bridge expansion joints are effective enough to stop water and debris from entering the structure. However, they must be specifically created to improve the function and characteristics of the intended joint.

Each of these common types has a particular application technique and set of guidelines that must be followed to guarantee the joint's functionality. Expansion joints are crucial to the lifespan of a bridge and must be installed and maintained correctly to work effectively. 

Tactile Indicators 

Another common technique widely used for Australians' public safety is tactile indicators. It is estimated that the number of people with vision impairment is expected to double within the next 25 years as Australia's population continues to age. Thus, it should come as no surprise that those who are blind or visually impaired frequently have a variety of challenges when navigating built environments, such as poor orientation, trouble getting their bearings, and a higher risk of falling. 

This is where tactile indicators come into place!

Tactile ground surface indications (TGSIs), often known as tactile indications or tactile, are floor safety elements that help the blind and visually impaired move through public areas with assurance and safety. They are mainly used for two public safety reasons: directional guidance and warning against impending danger or obstacles.

Different materials are used to construct these items, which are made up of high bars or studs. To warn visually impaired people, contractors drill mushroom-shaped studs or mats into the ground surface.

As the environment can pose a series of threats and risks for those who are blind or visually impaired, the Australian Standards have created several projects and recommendations to increase accessibility and equality for everyone. 

So today, in Australia, public areas are designed and planned optimally with tactile indicators in Adelaide to provide critical directional information and warnings of approaching risk.

These are commonly installed at:

• Escalators

• Crosswalks, 

• Bus stop or train station

• Ramps or ramp landings

• Stairs

• Open spaces

• Building entrances

Final Thoughts

Navigating the built environment can be challenging for Australians without vision impairments and those living in high-traffic areas. Whether it's a new project or a renovation, as a community, we should prioritise ensuring everyone has safe and equal access.
