Step 3: Excavation and Groundworks

Let’s now venture into the heart of the operation – the excavation and groundwork phase. This step is where the rubber meets the road, translating plans into tangible progress. Here, we navigate through each intricate procedure, elucidating the rationale and strategic insights that govern these processes.

3.1 Excavation

In the excavation phase, we initiate the hands-on groundwork, a pivotal phase in transforming our plans into reality. Leveraging specialized machinery, we meticulously carve out the designated areas, setting the stage for the ensuing structural works. Real-world insights from successful projects highlight the importance of adopting environmentally friendly excavation techniques, which mitigate adverse impacts on the surrounding ecosystem.

Excavation and Groundworks

In the preparation phase, it is essential to eliminate all weeds and any undesired organic materials, as well as remove the topsoil. Additionally, soft spots in the ground should be excavated down to the formation level, which serves as the lowest point to commence building a proper foundation. These excavated areas should then be filled with compacted sub-base material to ensure stability.

 

In cases where weed growth is a concern, it is advisable to treat the excavated subgrade with a general weedkiller like Glyphosate, although it’s unlikely that weeds will penetrate the upper layers of the construction. For situations where deep-rooted and persistent weeds pose a problem, or if there are doubts about the strength and quality of the subgrade, the use of a Geo-membrane can be considered. This Geo-membrane serves as a barrier to prevent weed penetration and provides additional reinforcement to address potential sub-grade issues.

3.2 Subsoil Drainage

During this stage, we engineer a robust drainage system that safeguards the project against water-related complications. Examples from the field illustrate how expertly designed drainage systems prevent water-logging and ensure the longevity of the road infrastructure, showcasing the symbiosis between site engineering and sustainable development.

3.3 Utility Relocation

Occasionally, roundabout projects necessitate the relocation of existing utility infrastructure.

Through this segment, I provide a glimpse into the scientific and artistic dimensions of crafting retaining walls that are both sturdy and aesthetically complementing the roundabout’s design.

Step 5: Road Construction

The fifth phase of our journey in site engineering of a road roundabout project entails the meticulous construction of the road itself. It is a step where the synergies of various elements come into play, paving the way for a structure that promises both durability and finesse. As we forge ahead, let’s delve deeper into each facet that contributes to building a road that stands the test of time and serves the community proficiently.

5.1 Sub-base Layer

Our first task is to lay a robust sub-base layer, the unsung hero that provides structural support to the subsequent layers, such as the Type 1 sub-base.  Using scientifically vetted materials, we ensure that the sub-base is compacted adequately to withstand the traffic loads it will eventually bear. It’s a stage where we combine science and precision to craft a layer that promises durability. In this endeavour, site engineering plays a pivotal role in selecting materials that not only offer structural integrity but also align with environmental sustainability, a testament to our commitment to crafting infrastructures that are in harmony with nature.

The sub-base layer typically serves as the primary load-bearing component of a pavement system. Its primary purpose is to distribute the weight of the pavement and any traffic that traverses it evenly across the sub-grade beneath. An effectively constructed sub-base layer offers several advantages, including aiding in proper drainage, preventing settling, and eliminating channelization – a common issue seen in low-quality block paving installations, where depressions or “ruts” form due to repetitive traffic patterns, such as daily travel to a garage.

Channelization is also noticeable on roadways, especially near traffic lights and uphill sections. The sub-base layer is engineered to counteract these issues and maintain a stable surface.

The sub-base layer functions by dispersing a concentrated load over a larger area. The interlocking structure between adjacent particles of the sub-base material ensures that even a relatively thin layer of appropriately crushed aggregate can significantly enhance the ground’s capacity to support heavy loads.

It’s crucial not to underestimate the load-bearing capacity of a 100mm sub-base layer. With just a few centimeters of the right type of material, compacted correctly, it can transform an unstable sub-grade prone to rutting into a robust surface capable of accommodating cars and other vehicles. This transformation occurs through a process known as “Load Spreading,” where the granular material spreads the concentrated loads over a much wider area, enabling the support of substantial loads without experiencing settling or permanent deformations.

5.2 Base Layer

As we progress, the next milestone is the installation of the base layer. Here, I guide you through the intricacies of ensuring that it adheres to the requisite thickness and quality standards. Utilizing cutting-edge technology, we lay a base that promises resilience and longevity. It’s a process that embodies precision, where each inch laid is a step towards crafting a roadway that promises smooth journeys for years to come.

This layer serves as a crucial load-bearing component of the pavement and ideally should measure at least 40mm in thickness, with a preference for a 50mm thickness. The material used for this binder course is coarser in texture compared to the wearing course. It typically consists of 20mm or 28mm aggregate mixed with a bitumen binder, commonly referred to as Dense Bitumen Macadam (DBM). In situations like public highways and other high-traffic areas, the binder course may have an additional base layer beneath it.

 

For binder courses ranging from 50mm to 80mm in thickness, a 20mm DBM material is recommended. When the binder course needs to be thicker, within the range of 70mm to 150mm, opting for 28mm DBM material is advisable. It’s essential to lay the binder course material evenly, maintaining a reasonable level with a tolerance of ± 10mm. This material should then be thoroughly rolled and compacted before proceeding with the application of the wearing course. In cases where larger areas need to be covered, specialized paver machines designed for bituminous material application are often employed. This method typically results in a more accurate and level surface compared to manual laying techniques.

5.3 Wearing Course

Tarmac Wearing Course

At this juncture, we, are often referred to as the binder. This layer is the face of the road, a tactile interface between the surface course and the infrastructure. Through my guidance, you’ll comprehend the technology that governs the laying of this layer, ensuring a surface that offers uniformity and supreme quality. 

When the surface course is scheduled to be applied immediately after or shortly following the base course, these layers will naturally bond together. However, in cases where a significant delay, lasting more than one week, is anticipated between the completion of the base course and the installation of the wearing course, it becomes necessary to seal the base course using a specialized sealing grit.

Sealing grit is composed of bitumen-coated grit particles, typically around 3mm in size. It is evenly spread across the compacted surface of the base course and then brushed in, filling any gaps or voids within the base course. This process serves the purpose of preventing these gaps from being filled with mud or any other undesirable contaminants during the waiting period.

Before applying the final wearing course, which could be several weeks or even months later, it’s essential to coat the base course with a bonding emulsion. This step ensures proper adhesion between the base and wearing courses, enhancing the overall durability and performance of the pavement.

5.4 Surface Course

The surface course is the topmost layer of a bituminous pavement, the part that is visible and subjected to traffic. Its smoothness is crucial, particularly for higher-speed roadways, though it holds significance for residential driveways as well. Typically, a macadam surface course comprises small, durable aggregates, usually measuring 6mm or 10mm, bound together with bitumen or asphalt.

Alternatively, an asphalt surface course, sometimes referred to as a sand carpet or asphalt carpet, can be employed. This material is manufactured in a batch plant following a specific recipe, which includes selected sands and grits mixed into an asphalt matrix. Coated chippings are then spread and rolled into the asphalt during the compaction process. Depending on the project’s size and accessibility, this surface course may be applied either by machinery or manually.

For the wearing course, it’s essential that it reaches a minimum thickness of 20-25mm when compacted, and it should maintain a level within a tolerance of ± 6mm. The finished surface should exhibit no roller marks. It is recommended to have a minimum fall of 1:80 for tarmac areas, although a fall within the range of 1:40-1:60 is preferable to ensure proper drainage.

5.5 Quality Checks

As we approach the finale of the road and roundabout construction phase, quality checks stand as a gatekeeper, ensuring that each layer complies with the predetermined standards. Through a series of rigorous inspections and tests, we ascertain that the road is poised to meet the expectations set forth. In this segment, I will take you through the various quality control mechanisms that are in place, offering a lens into the world of site engineering where quality is not just a requirement, but a commitment. These checks stand as a testimony to the diligence and expertise that go into crafting road roundabout projects that are synonymous with excellence and safety.
