Alongside the new models in its range, the company also presents new technological concepts that outline the paths to be followed in the future.

Simex for Cold In-Situ Recycling of Surface Asphalt Layers: the ART 1000 Technology Released in the New GEN II Version

At Bauma 2025, the new version of ART 1000, the patented technology developed by Simex for in-situ regeneration of deteriorated asphalt, will be presented in its latest GEN II version.

Simex ART is an innovative technology that focuses on surface-level interventions for the functional recovery of road deterioration. It does not require the removal of milled material or the addition of virgin bituminous mix, instead utilizing only the existing on-site material. Most importantly, it avoids the complete interruption of vehicular traffic, ensuring the road is immediately passable after restoration.

During the milling phase, the equipment uses an eco-friendly chemical rejuvenator to cold-recycle the bituminous aggregate produced. Specifically, ART consists of two drums: the first for milling and mixing, and the second for crushing and disintegration.

In its working phase, the ART 1000 combines the following processes:

• Milling of the deteriorated road section

• Controlled injection of rejuvenators proportional to the working depth and the carrier's speed

• Reduction of the milled material to the correct grain size

• Final mixing to create the recycled bituminous mix ready for compaction

After regeneration, the bituminous mix is deposited directly into the milled track and is ready to be leveled and compacted with a roller or vibrating plate.

It should also be noted that, as in the case of repairs after the installation of fiber optics, the presence of cement mortars in limited proportions compared to the total volume of milled asphalt does not compromise the success of the final restoration.

In addition to the logistical advantages on-site and in terms of traffic flow, the ART 1000 technology offers other key benefits that are worth highlighting:

1. Reduction of costs associated with the purchase and transport of new raw materials, utilizing exclusively the bituminous mix available on-site.

2. Environmental sustainability: the recovery and regeneration of 100% of the on-site material, as well as a reduction in construction traffic, which is implied by the supply of new materials and the removal of excavated materials.

3. Fast and durable surface restoration, allowing for proper planning of interventions at sustainable costs.

NEW! ART 1000 – GEN II: Onboard Technology and Regeneration Control

Video Display and Full Control Over Regeneration Dynamics

In the past year, Simex has enhanced the onboard electronics of the ART 1000 to better meet the daily needs of road construction sites.

The onboard electronics have been further developed with the addition of a new video interface to improve connectivity between the operator and the ART 1000 technology. This interface displays real-time values such as linear meters (progress), liters per meter (additive dosage), and actual liters (additive consumption). It is possible to manually set a precise amount of rejuvenator (with a sensitivity of 0.1 l/min) according to the manufacturer's specifications and the site's environmental conditions. The Simex software calibrates and adjusts the rejuvenator dosage according to the change in the carrier's speed, based on parameters entered by the operator at the start of the job. The control display is paired with an LED indicator installed above the equipment in an ergonomic position, making it easy for the operator to monitor and ensure the correct speed for effective material mixing. The 8 LED light scale gradually lights up: the first two indicate a speed that is too low, and the last two indicate a speed that is too high. The middle range, highlighted in green, suggests the ideal speed for proper regeneration of the milled material.

Easily Removable Additive Tank for Easy Maintenance

The 100-liter rear tank is now removable from the side, and thanks to a drainage cap located at the bottom, it can be easily emptied if necessary. Additionally, the lateral movement of the tank allows access to the second drum compartment (crusher) from above, for cleaning and maintenance.

Redesigned Material-Size-Control-Grille for Easy Removal

The grille that determines the correct grain size of the material exiting under the second drum is also easily removable from the side for proper maintenance and cleaning at the end of the day. The removable tank and grille have been designed to ensure safe and easy access to the crusher drum of the equipment.

The Evolution in the World of Utilities: Simex Accelerates the Development of New Cutting Discs for Matching with a Wide Range of Wheel Saws. The Goal: Increased Productivity and Precision with Reduced Wear.

Fiber Optic Networks: Simex at the Forefront of Developing New Wheel Saws for Mini and Micro-Trenching Applications.

Unlike traditional trenching, mini and micro-trenching offer much faster execution, significantly less waste material, and considerably lower restoration times and costs. Additionally, the ability to use smaller machines reduces the size of construction sites, benefiting road traffic, especially in urban areas. Since 1995, when Simex launched its first wheel saw in the Italian market, the company has been at the forefront of creating equipment for trenching of various widths and depths. Specifically, Simex has always focused its efforts and investments on mini and micro-trenching, particularly for the installation of fiber optic networks.

A mini-trench typically refers to an excavation with a minimum width of 50 mm and a maximum of 150 mm, with a depth between 300- and 400-mm. Micro-trenching, on the other hand, is distinguished by its cutting width, which ranges between 16 and 25 mm, and a maximum depth of 250 mm. Today, Simex offers 15 models of wheel saws specifically designed for narrow trenching applications. These machines are divided into three product ranges: RW and T for mini and midi loaders, and the RWE line for excavators of different sizes.

NEW! The Introduction of New Cutting Discs for Wheel Saws: PCD Tools, Available for Both Monolithic and Sector Wheels.

For micro-trenching cutting applications, the most widely used solution has traditionally been rotating conical carbide-tipped tools. While this type of tool is widely and effectively used in milling and digging heads, it begins to show its limits in micro-excavation or cutting applications. The miniaturization of the traditional solution inherently causes significant stress on the tool's surface due to the high localized contact force. As a result, tungsten carbide conical tools, although relatively inexpensive, suffer from rapid wear and limited lifespan, often requiring daily replacement by operators.

To overcome this limitation, Simex has introduced a special tool where the tungsten carbide is externally coated with a sintered polycrystalline diamond (PCD) deposit.

The hardness provided by the diamond surface significantly extends the tool's lifespan during excavation applications, allowing for longer work distances without the need for frequent maintenance. The sintered diamond's properties also allow for higher peripheral speeds of the cutting disc, meaning faster rotation, which translates into increased daily productivity for the operator. Additionally, the cutting edge profile has been changed from conical to cylindrical, offering better cutting characteristics and ensuring cleaner excavation with a sharper, cleaner cutting profile.

To address the issue of the PCD tool inserts being brazed onto the base disc, Simex has introduced a sector (segment) variant that improves serviceability, enabling operators to regenerate these segments and avoid disc replacement (no waste).

The new tools are compatible with all compact wheel saws, specifically designed for micro-trenching applications in fiber optic network installations for final connections to buildings, where compact machinery is required. These models include RW 150, 300, and 350. The unique feature of these machines lies in their versatility: they are designed for mounting on mini and midi excavators (1.5 to 10 tons) as well as for use on mini loaders, with the addition of a lateral translator.

The smallest model, RW 150, in the boom version, is called RWE 15, and ensures small-section cuts and excavations on hard and compact surfaces such as asphalt and concrete, with widths of 25, 30, 40, and 50 mm, at depths of 100, 125, or 150 mm.

Models RW 300 and 350 (RWE 30 and 35 in excavator configurations), similar to the smaller RW 150, can also be paired with an excavator arm and offer operators several operational advantages. They are equipped with a self-leveling tilting system: thanks to a jointed support that rotates on the drum axis, the skids always remain stable on the ground, ensuring consistent excavation depth regardless of the road surface irregularities. Additionally, the design of the discharge openings and the mechanical/manual excavation emptying system ensure proper expulsion of the milled material, leaving the trench clean at the set depth. The various available cutting discs allow for trench widths of 25-30-40-50-80 mm, with adjustable depths of 200-250-300-350 mm through manual-mechanical adjustment.

Drum Cutters: Application Versatility and a New Line for Narrow Trench Excavation

In the past year, Simex has further expanded its already wide range of drum cutters by refining existing models and addressing the more complex working situations to meet the demands of an ever-evolving market. Versatility is precisely what makes the drum cutter a versatile piece of equipment applicable in different contexts.

TF Double Drum Cutter Heads

The double drum cutter heads have seen both an expansion of the range – with the addition of the TF 2500 for excavators from 40 to 55 tons – and a revision of the TF 600 and TF 400 models, which have been updated to the TF 650 and TF 450. The update comes from the need to standardize these models with the larger models, featuring a double filter on both the supply line and drainage line, both integrated to protect the hydraulic system from external impurities that could damage or reduce the performance of both the excavator and the equipment. Additionally, the redesigned frame allows the excavated material to exit the trench without the risk of getting stuck in the structure, now allowing flexible hoses to be connected on both the sides and front of the equipment.

NEW! TFN 2600 NARROW DRUM CUTTER: A Special Model to Be Revealed at Bauma

Simex is launching a new drum cutter model with a new design and reduced distance between the drums, realized for maximum performance in trench excavation. The increased torque and high cutting force, all within a more compact structure, will optimize performance both on the ground and on the walls.

Continuous Cutting Drum Cutters TFC and Universal Drum Cutters TFU

The TF technology finds its natural complement in the TFC range, for excavators in the 1.2-12 ton category. This system features a double drum with a central chain that provides a continuous cutting profile without interruption in the middle between the drums. Highly appreciated for scarification and vertical profiling work, they are also frequently used for root and stump crushing or soil tilling.

Recently introduced to the range, with the TFU models Simex combined drum cutter technology with wheel saws for excavator arms, creating equipment that can be configured according to the customer's needs. The universal drum cutters can be equipped with either a drum cutter or a cutting disc. In the first configuration, the machine is ideal for scarifying and profiling hard, compact surfaces such as asphalt and concrete. In the second configuration, the wheel saw model can perform small excavations, cuts, and trenches with widths ranging from 30 to 200 mm, for working depths up to 450 mm.

A new approach to screening: Introducing a new range of buckets to maximize performance in landscaping, soil cleaning, and compost aeration

Simex is exploring new areas of material separation directly on-site, focusing on cost savings, site dynamism, and environmental sustainability.

Selective separation and screening of materials directly on-site is becoming an increasingly important topic for earthmoving operators, opening new market scenarios and developments. Treating waste materials on-site, when possible, brings numerous benefits, especially in terms of saving time and money—two key elements that drive all construction site dynamics. Simex, analyzing its target market, has identified two main application areas that have seen significant growth in recent years:

HEAVY DUTY – Screening of demolition waste aggregates.

LANDSCAPING & SOIL REGENERATION – Soil cleaning from debris for horticulture and green area restoration.

In both cases, the goal is to preserve all "valuable" materials that can be recovered and reused directly on-site or more easily transported off-site. In the case of demolition waste aggregates, material rehabilitation on-site significantly reduces disposal costs and cuts costs related to the purchase and transport of new raw materials. In the second case, soil recovery, it is important to highlight that, in many construction sites, with adequate screening work, on-site soil can be cleaned of stones, roots, and debris, disposing of only the inert portion. The cleaned soil, free from debris and screened with Simex screening buckets, is immediately usable, aerated, and of the right size for subsequent planting.

NEW! VSE TORNADO: A new line of screening buckets specifically designed for soil cleaning and aeration, even when wet and muddy

Simex expands the horizons of screening with the launch of a new range of screening buckets for excavators, designed for light applications such as landscaping, green area maintenance, gardening, and small urban construction sites where space constraints require minimal equipment size. This new product allows screening, reducing, cleaning, and aerating in a single pass: organic waste and soil, accelerating the composting process, and producing a screened material of the ideal size for restoring green areas and subsequent planting. The minimal waste produced significantly reduces the costs of disposal at specialized centers.

All details will be revealed on the first day of the fair.

FIT: Special configurable screening tools 

The patented FIT tool system features independent, removable, and replaceable screening elements. Each disc or blade attaches to the central element and the shaft without any welding. This results in up to 75% savings in maintenance costs (compared to the previous system). The replacement process does not require disassembling the shafts; each element is individually replaceable in just a few minutes, directly on-site. The system provides high versatility for operators, adapting to the type of material being screened. Simex offers four configurations, but other combinations are possible with interchangeable discs of different shapes and sizes.

The new products will be revealed on the first day of the fair. We look forward to seeing you on April 7th at Hall C5, Stand 325, to discover together the solutions that define the future.
